Maintenance technology of metallurgical machinery and equipment

The comprehensive development of the economic system has led to the rapid rise of the metallurgical industry, and the metallurgical industry also occupies a leading position in driving the development of the national economy and industry. The key to ensuring the output and quality of metallurgical mining is the efficient and stable operation of metallurgical machinery and equipment. In actual operations, mechanical equipment will have wear and tear failures and equipment failures caused by extreme environments, which will affect the working efficiency and service life of the equipment. How to prevent such failures in advance and how to quickly repair them after encountering failures are the focus of this study.

1  Improving the maintenance technology level of metallurgical machinery and equipment is of vital importance to ensuring production efficiency and quality

1.1  Promoting the effective improvement of metallurgical production efficiency

With the widespread application of mechanical equipment, the production method based on manual and simple equipment has been replaced by modern mechanical operations. With the help of the fast characteristics of mechanical equipment, people have effectively improved production efficiency. The introduction of modern technology has greatly improved the efficiency of metallurgical operations. For metallurgical enterprises, equipment maintenance and maintenance are crucial. If the equipment cannot be detected and analyzed in time, failures will occur, which will affect the operation of the entire metallurgical production chain.

1.2  Ensure the quality and production efficiency of metallurgical products

In order to achieve the production development of metallurgical enterprises, it is necessary to obtain certain material resources so that they can operate more efficiently. So, how many people should be equipped in metallurgical enterprises? All of these must be taken into consideration. From this, it can be inferred that the production process of an enterprise requires not only a team of skilled workers, but also a complete set of automated equipment, otherwise the entire production process will be difficult to complete smoothly. In order to ensure the normal operation of metallurgical enterprises, it is necessary to strengthen the management and use of mechanical equipment to ensure the quality and efficiency of metallurgical products. With the changes of the times, the development needs of the metallurgical industry have exceeded the scope of traditional production models. In order to improve production efficiency and product quality, it is necessary to improve the original production model. Its low operating efficiency consumes a lot of human resources, and also has a negative impact on mining costs, thereby reducing mining quality. Therefore, only modern management methods can ensure the normal operation of production. For this matter, the person in charge must have a thorough understanding and optimize and improve from multiple angles. In order to ensure the normal operation of the mine, a complete management system should be established to strengthen the management of equipment and maximize its role. By using advanced equipment maintenance technology and scientific production processes, the production chain can be optimized, which is more conducive to the economic construction of the enterprise.

2  Problems that need to be solved in the maintenance and management of metallurgical machinery and equipment

2.1  The performance of the device failed to meet the expected level

In the actual metallurgical construction process, most technicians failed to fully consider the aging of mechanical equipment and failed to follow the relevant specifications of high-tech production for construction, which may lead to some defects in the performance and quality of the products produced. Secondly, due to the lack of advanced smelting equipment and processes, the economic benefits of the enterprise have suffered a serious impact, which is an issue that cannot be ignored. In addition, due to the long-term use of metallurgical machinery and equipment, it has suffered varying degrees of damage, which in turn affects the normal operation of the entire project. Therefore, in order to ensure the quality and production efficiency of metallurgical machinery, it is necessary to strengthen its maintenance and maintenance. In addition, once a metallurgical machinery and equipment fails, it will not only affect normal use, but also cause certain economic losses. With the extension of service life, the degree of wear of metallurgical machinery and equipment will gradually increase, and eventually it will not be able to meet the needs of high-intensity production, and will gradually be eliminated. In addition, due to the relatively harsh operating environment of metallurgical machinery and equipment, once a failure occurs, it will cause great economic losses and even affect the normal operation of the entire factory and even the society. At present, my country’s metallurgical industry is facing huge challenges. If timely countermeasures are not taken, it will bring immeasurable economic losses to the country. Therefore, how to ensure the safe and stable operation of metallurgical equipment is an urgent problem to be solved. In order to ensure that the existing metallurgical process equipment is updated and upgraded within a certain service life, it must be innovated and improved in a timely manner to adapt to the ever-changing environment and needs.

2.2  Due to the lag in equipment management methods, serious polarization has occurred in society

At present, many metallurgical enterprises in my country have not yet reached a high level in equipment management, and this situation is common among managers. Most employees do not pay enough attention to equipment management and do not clearly understand its importance. These employees consider themselves to be middle-level managers of the company, rather than the main person in charge of the equipment management department, so they often only focus on improving work efficiency and economic benefits at work. This concept has greatly affected the enthusiasm and initiative of employees. The main reason for this phenomenon is that managers fail to fully understand the actual production situation of the enterprise, so there is a certain disconnect between the relevant management systems and countermeasures formulated and the actual output. At the same time, some enterprises also lack the awareness of the application of mechanical equipment fault analysis and diagnosis technology, which has caused a series of safety accidents. Therefore, to completely solve this problem, it is necessary to carry out source control in mechanical equipment management to ensure its effectiveness. At present, most steel enterprises in my country have realized the transformation of the professional management mode of mechanical equipment, but the maintenance of mechanical equipment has not attracted enough attention. Although grassroots employees have the ability to fully understand the actual production situation of the enterprise, due to the limited power, they cannot really solve the problem, which leads to the inability of many mechanical equipment to operate scientifically and reasonably, and ultimately makes the maintenance and management of metallurgical mechanical equipment face many problems, making it difficult to ensure future production efficiency.

2.3 The installation of the device has defects

In the installation process of metallurgical equipment, the main challenge is the lack of installation personnel with professional skills, the management level needs to be improved, and the quality of the personnel responsible for installation needs to be strengthened. Therefore, in order to ensure the smooth completion of the project, it is necessary to strengthen the management of the installation process of mechanical equipment. Because some construction units failed to pay enough attention to the inspection and supervision of the installation quality of mechanical equipment, the construction effect failed to achieve the expected goal. Because the construction personnel did not master the correct installation method, the performance of the equipment after installation could not be brought into the best state. In the actual installation process of mechanical equipment, parts are often confused and lost, which shows that the staff has certain omissions and carelessness in their attitude towards work. Many technicians did not strictly follow the specifications and standards, so that the installation results deviated from the original design goals, which in turn affected the overall performance and service life of the equipment. The normal operation of the equipment will be adversely affected by the installation environment, including but not limited to high humidity, excessive temperature and other factors. During the installation of the machinery, safety accidents may also occur due to the insufficient technical level of the operators, thereby reducing the service life of the equipment. Due to the influence of the above factors, many metallurgical enterprises have not been able to effectively improve the efficiency of equipment installation, and have not reasonably planned the working time, which has led to a serious weakening of the use efficiency of the equipment.

3  Apply control strategies to maintain the normal operation of metallurgical machinery and equipment

3.1  Routine maintenance

In the daily production and construction process, special attention should be paid to the use of metallurgical equipment that is sensitive to changes in the external environment. Because the equipment has been in a harsh environment for a long time, it will cause corrosion and wear, which will reduce its service life. After a period of operation, the equipment needs to carry out a series of maintenance work, including replacing damaged parts, applying lubricating oil to areas susceptible to wear, and adjusting the operating accuracy of the equipment to extend its service life. In order to ensure the normal operation of the equipment, it is necessary to do a good job of relevant maintenance work, eliminate faults in time, and keep it in good condition. During use, it is important to pay attention to daily operations and avoid operating in high temperature and high pressure environments to ensure the safety of operation. If possible, regularly clean and clean its internal parts. When the machine is idle, it must be dusted and purified to ensure that it is clean and flawless. For metallurgical machinery and equipment that have been put into use, a series of activities such as cleaning, maintenance and repair should be carried out regularly. For those metallurgical equipment that is in use or not in use, regular and regular maintenance must be carried out to ensure that it operates at a highly stable level. In the process of making metallurgical products, attention should be paid to raw material quality control to avoid product quality degradation caused by raw material quality problems. Only in an efficient working environment can the production and construction of metallurgical products be ensured to meet the market environment requirements proposed by them. For the metallurgical industry, it is necessary to do a good job in the repair and maintenance of metallurgical machinery and equipment to ensure its good operating condition, so as to create greater economic benefits for the enterprise. With the continuous evolution of the market environment for the operation of metallurgical machinery and equipment, periodic data has shown a trend of diversification and complexity. Therefore, maintenance technicians must strengthen the in-depth analysis of data.

3.2  Perform post-maintenance and repair

When metallurgical machinery and equipment are worn or technically faulty, relevant personnel will carry out targeted repairs to ensure the long-term stable operation of the equipment. This is the so-called post-maintenance. It is one of the important safeguards to ensure the normal operation of the equipment, and it is also a very practical and economical maintenance method. Under normal circumstances, the requirements for this type of maintenance technology are quite high. In order to effectively eliminate the safety hazards of the equipment and accurately locate the fault location, targeted maintenance must be carried out according to the type of fault. Therefore, the daily maintenance and repair of metallurgical machinery and equipment have an important impact on the production efficiency and safety performance of the enterprise. Due to the heavy load, high impact load, low speed and other characteristics of heavy rolling mills, problems such as the destruction of the equipment oil film and the torsional deformation of the bearing structure are very easy to occur. Therefore, for this type of mechanical equipment, relevant personnel must carry out corresponding inspections. At the same time, in order to ensure the normal operation of mechanical equipment, reasonable and effective maintenance strategies should be adopted to ensure that its service life is extended. In addition to management, maintenance work also needs to start from the perspective of science and technology, and constantly update maintenance technology to improve the use efficiency of equipment. At present, many enterprises in my country have established their own maintenance systems and achieved good results. In order to meet the needs of industrial development, a new type of maintenance technology is adopted, that is, through a scientific and effective management system, the equipment operation status of network planning technology is displayed on the computer screen. In the specific practice process, it is also necessary to formulate practical measures in combination with the actual situation on site to ensure that the equipment is in a good state. Therefore, clear measures can be established to achieve the goals of maintenance and control. Maintenance personnel can also use advanced computer technology to analyze and deal with various problems, thereby ensuring the normal and stable operation of the entire system. Under such a technical background, maintenance personnel can deeply understand the relationship between each link and sequence, so as to more clearly grasp the operation of the entire system. At the same time, they can also timely grasp the information such as the operation status and cause of failure of the equipment, so as to provide a scientific basis for formulating a reasonable and feasible maintenance plan. The network structure diagram can fully present the observation data status generated by each equipment operation link, thereby providing a comprehensive information display.

3.3  Carry out predictive maintenance

In production practice, the accuracy of preventive maintenance is relatively low, and there is a certain lag in post-maintenance. In contrast, predictive maintenance has greater advantages by effectively detecting metallurgical machinery and equipment to determine its specific conditions. Predictive maintenance has good practicality. It can detect and eliminate some potential faults in advance, thereby reducing unnecessary losses. Since it can monitor the device in real time, it can automatically issue an alarm based on the displayed data status to ensure that the device fault is detected in time. This paper mainly analyzes and discusses the predictive maintenance technology of metallurgical machinery and equipment. On this basis, corresponding early warning and data support are proposed to assist maintenance personnel to understand the root cause of the fault more comprehensively, thereby improving the overall efficiency of maintenance work.

3.4  Improve the technical management level of metallurgical machinery and equipment to achieve a more perfect effect

In the production process, metallurgical enterprises must continuously promote the innovation of metallurgical machinery and equipment production technology, comprehensively upgrade the equipment management technology of metallurgical machinery and equipment production sites, and actively carry out the supervision and management of metallurgical machinery and equipment production quality. In order to ensure the normal operation of metallurgical machinery, relevant equipment maintenance work must be done well. When carrying out equipment maintenance, the first task is to clarify the degradation position of the equipment, fully understand the degradation speed and maintenance cycle of the equipment, and fully consider the impact of equipment failure on the product. Secondly, according to the problems that may occur during the operation of the equipment, corresponding preventive measures should be formulated to ensure the safe and smooth production. Under normal circumstances, when the key equipment on the production line fails or has a minor impact on production, but the failure will cause serious damage to the equipment or cause casualties, regular maintenance and management measures must be taken. Once a major failure or accident occurs, effective countermeasures should be taken in time to solve it and ensure that the equipment is in a safe operating state. In the absence of any negative impact on production and equipment, post-maintenance is a feasible measure. In addition, for the common problems in the production process and management of metallurgical machinery and equipment in my country at this stage, an in-depth analysis was conducted, and a series of preemptive measures were taken to deal with them one by one. Finally, more advanced and more suitable metallurgical machinery and equipment maintenance and management technical solutions were adopted. These solutions can be put into practice by metallurgical machinery and equipment operators and maintenance personnel, thereby comprehensively improving the efficiency and quality of metallurgical machinery and equipment maintenance work.

4  Future development prospects of the metallurgical machinery and equipment industry

The metallurgical machinery industry should strengthen the training of talents that combine theory and innovation, which is the cornerstone of the development of the metallurgical machinery industry. Provide learning opportunities and international learning and exchange platforms for industry personnel, introduce internationally advanced machinery and equipment and maintenance technologies, and reward and introduce cutting-edge technical talents. Provide a broader development space for metallurgical machinery talents and enhance their sense of professional achievement and honor. Only with the continuous innovation of technical talents can the long-term development of the metallurgical machinery and equipment industry be better promoted.

Metallurgical machinery and equipment will produce waste emissions, noise, thermal radiation and other pollution during operation. How to reduce the energy consumption of metallurgical equipment, combine green and environmentally friendly production with metallurgical machinery and equipment, how to recycle and reasonably utilize industrial waste, create a production model that integrates the environment and operations, and improve the working quality and efficiency of metallurgical machinery and equipment are the future development directions of the metallurgical machinery industry.

The performance of metallurgical machinery and equipment combined with laser cladding technology will be more stable and the service life will be longer.

5  Conclusion
