A brief analysis of the development of metallurgical machinery and automation in China

    In recent years, the research and development of metallurgical machinery in our country have made great achievements. In 2008, Anshan Iron and steel company built 2.15 meters hot rolling mill and 2.13 meter continuous rolling mill, and put it into use. Large heavy plate mill has basically been made domestically.
    
    With the rapid development of China's economy, the development of various industries in the national economy can not be separated from the support of the metallurgical industry. The metallurgical industry has a very important strategic significance for the stable development of our national economy. The modern metallurgical industry of our country started relatively late. From the 70s of the last century, through the introduction of foreign technology and equipment, the metallurgical industry has been digested and absorbed on this basis. The metallurgical industry of our country has made great achievements and has gradually established an independent and relatively complete metallurgical industry system. It is of great significance to the development of China's national economy. At the same time, the domestic research on metallurgical machinery and equipment has made progress. With the development and expansion of China's metallurgical industry, the level of metallurgical machinery and the degree of automation in our country have been greatly improved, and it has gradually developed towards the direction of large-scale, comprehensive and integrated. Since the new century, with the development and continuous maturity of the computer technology as the core information technology, the automation of China's metallurgical industry has gained a great leap forward development.

    In recent years, great achievements have been made in the research and development of metallurgical machinery in our country. In 2008, Anshan Iron and steel company built 2.15 meters hot rolling mill and 2.13 meter continuous rolling mill, and put it into use. The rolling mill has basically been made in China. At present, the research of metallurgical equipment in our country is gradually developing towards the direction of independent research. The research and development of cold continuous rolling mill has made breakthrough progress, and the conventional metallurgical equipment can be basically made in China. With the rapid development of metallurgical machinery and equipment in China, the development of metallurgical automation technology has brought wide development space, laid a solid foundation, basically realized the automation of raw material production and coking production, which greatly promoted the development of China's metallurgical industry. With the development of China's computer technology and the wide use in various fields, a large number of computer technology has been introduced in the process of metallurgical automation in China, which has raised the efficiency of management, reduced the cost, improved the overall development level of the metallurgical industry, and laid a solid foundation for the stable and rapid development of the national economy in our country. The foundation of the reality.

    As early as 2006, the automation system integration project in metallurgical industry was dominated by control (large PLC) and transmission. The integrated business of automatic system is involved in the links of raw materials, sintering, coking, blast furnace, converter, electric furnace (Lian Gang), refining furnace, continuous casting, rolling mill, heating furnace, heating furnace, ferroalloy electric furnace, aluminum electrolysis and so on. Among them, PLC is especially the mainstream control system in metallurgical industry. In metallurgical industry, the automation of steel rolling is very high. It includes automatic combustion control model, rolling rhythm control model, rolling mill automatic width control model, finishing model of finishing rolling, shape setting and control model, exit temperature control model of finishing rolling, coiling temperature control model, coiling setting model and so on. PLC, hardware and software control are very important. It brings new opportunities for the development of metallurgical automation.

    The development of computer technology has made a qualitative leap in modern mechanical automation. At present, it is possible to develop a new generation of intelligent PCNC CNC system, which adapts to the complex manufacturing process and has closed loop control system structure. The intelligent new generation PCNC CNC system has the computer technology, network technology, CAD/CAM, and server. The control, adaptive control, dynamic data management and dynamic integration of high and new technologies, such as tool compensation and dynamic simulation, are integrated to form a close loop control system of manufacturing process. The application of this new technology in metallurgical machinery manufacturing will bring new opportunities for the development of metallurgical industry.
