Metallurgical equipment manufacturing power, intelligent and green development!

Metallurgical equipment is mainly for steel and non-ferrous metal processing industry to provide metal smelting, rolling, casting and other production special equipment. Metallurgical equipment manufacturing industry products are mainly divided into the following categories: iron making equipment, steel making equipment, metal rolling machinery, metallurgical ordinary casting equipment, roll metal special equipment parts.

Metallurgical equipment as a supporting product of the steel and non-ferrous metal industry, its product performance not only meets the needs of the steel and non-ferrous metal industry in terms of technical requirements, but is equally important in terms of production safety and stability, so the development of the metallurgical equipment industry and the formulation of quality standards have an important impact on the steel and non-ferrous metal industry.

China has become a powerful country in metallurgical equipment manufacturing, but there is a big gap with the international advanced level in the key technology of large sets of cold and hot tandem mills

China is an industrial manufacturing power, steel production ranks first in the world, is the world's largest metallurgical equipment application market, the main equipment in weight 90% of the realization of localization, has the whole process independent design, independent integration of the construction of ten million tons of modern steel base capacity, but the level of domestic equipment manufacturing industry is low, products are mainly low-end, over-reliance on foreign technology, There are many problems in its development, such as lack of core technology, low innovation and R & D capability, such as lack of innovation in technology or equipment independently developed in China; There are shortcomings in large steelmaking and rolling equipment; Problems such as poor management (disorderly competition and internal friction among relevant domestic companies in terms of foreign projects).

With the development of modern social information technology, electronic technology and control theory technology, the international metallurgical equipment production integration technology has been greatly improved, and the following technical breakthroughs have been made in the large-scale complete sets of cold and hot tandem mill technology:

(1) The main drive of the mill adopts microprocessing to realize digital control;

(2) Rolling line to achieve classification full computer control and comprehensive automation;

(3) The practical application of modern control theories such as vector control principle, adaptive control principle and self-seeking optimization regulation.

These core technologies will greatly improve the equipment level of modern large-scale complete cold and hot tandem rolling mill. The domestic large-scale complete sets of cold and hot tandem rolling mill is still the traditional three-electric control, multi-stage computer control of the whole line and various production process mathematical models and other technologies, and there is a big gap with the international advanced level, and depends on Italy, Germany, Japan and other foreign technology is higher.

Exhibition is the main development trend of metallurgical equipment industry in the future

Intelligence is one of the future development trends of the metallurgical equipment manufacturing industry, which has the role of high efficiency, low consumption, high quality and environmental protection for the steel and non-ferrous industry manufacturing industry. However, because the intelligent level of China's manufacturing industry is in its infancy, there are still many difficulties in metallurgical equipment manufacturing automation technology, including online continuous measurement, real-time optimization of targets, comprehensive closed-loop control, etc., and there is still a certain gap in the application efficiency of equipment production compared with foreign countries. In the next step, China should carry out high-end intelligent remanufacturing with high technology content, high reliability requirements, and high added value as the core characteristics, improve the technical management level of mechanical and electrical products remanufacturing and the quality of industrial development, and achieve green growth.

Environmental protection equipment and technology is an important opportunity for the development of metallurgical equipment manufacturing industry. At present, the intensity of environmental protection governance is increasing, especially the pressure of energy conservation and emission reduction brought by the steel industry to fulfill the carbon peak and carbon neutrality, and the task of environmental protection of the steel industry is arduous. At present, the level of China's iron and steel manufacturing industry is uneven, many enterprises have not yet achieved a comprehensive stable emission of pollutants, energy conservation and environmental protection investment history of more debts, energy conservation and environmental protection facilities to be further upgraded, which is a big opportunity for metallurgical equipment manufacturing enterprises.
