"The development of new quality productivity is an inherent requirement and an important focus to promote the high-quality development of the steel industry." On September 26, at the fourth National steel industry "new knowledge, new technology, new ideas" exchange conference, academician of the Chinese Academy of Engineering, CPPCC Standing Committee, Vice Chairman of Hebei Province CPPCC Standing Committee, Central Committee of the Democratic League, Chairman of the Hebei Provincial Party Committee, President of North China University of Science and Technology Zhang Fucheng said, and Hebei steel industry as an example, introduced the steel industry new ideas, new technologies, new actions.

Zhang Fucheng believes that the development of new quality productivity is the fundamental way out for the high-quality development of the steel industry, new workers are the key force to promote the development of new quality productivity of the steel industry, new labor materials are the material basis for the development of new quality productivity of the steel industry, and new labor objects are the power source for the development of new quality productivity of the steel industry. It is necessary to build a new type of production relations commensurate with the new quality productivity.

Zhang Fucheng said that the new quality productivity is the leading role of innovation, get rid of the traditional economic growth mode, productivity development path, with high-tech, high efficiency, high quality characteristics, in line with the new development concept of advanced productivity. It is necessary to deeply understand that the development of new quality productivity is the fundamental way out for the high-quality development of the steel industry.

Zhang Fucheng said that the new type of workers is the key force to promote the development of new quality productivity in the steel industry, and the new type of workers are mainly characterized by strong scientific thinking, green concepts, learning ability and dedication. "The structural problem of talents in China's steel field is more prominent, showing an olive type, especially the serious shortage of leading talents, and the shortage of talents in emerging fields such as green and intelligent manufacturing." Zhang Fucheng admitted. He believes that the new type of workers in the steel industry mainly includes three types: first, strategic scientists who have a forward-looking vision and grasp the development needs and trends of the steel industry; The second is the first-class scientific and technological leading talents and innovation teams that can break through the disruptive and key core technologies in the steel field; Third, engineering and application talents who have mastered new production tools, artisans from large countries and workers with outstanding technical and labor skills.

"New labor materials are the material basis for the development of new quality productivity in the iron and steel industry. The new labor materials are mainly intelligent, green and high-end, and have stronger scientific and technological attributes." Zhang Fucheng said that among them, the new generation of information technology infrastructure, cross-field comprehensive infrastructure and advanced production tools represented by high-end intelligent manufacturing equipment are important cornerstones for the development of new quality steel productivity; New technologies such as big data, artificial intelligence, and cloud computing, as well as new processes spawned by scientific and technological innovation and new energy development and utilization, are strong driving forces for the development of new quality steel productivity.

Zhang Fucheng said that the new type of labor object is the driving force for the development of new quality productivity in the steel industry. The extension and expansion of a wider range of new labor objects can stimulate productive forces and develop new driving forces. For example, the upstream and downstream big data and intelligent management platform of the steel industry constitute data elements, realize the supply chain expansion of the steel industry, and ultimately realize the production management innovation of the steel industry, improve the total factor productivity of the steel industry, and contribute steel strength to strategic emerging and future industries.

In addition, Zhang Fucheng believes that the steel industry also needs to build a new type of production relations that is compatible with the new quality productivity, and the new type of production relations are contained in the three major fields of government, effective market and organic society. Among them, the government needs to do a good job in macro-control, control steel trade risks, and high-level foreign cooperation; Efficient market requires efficient allocation of steel production factor resources, promoting the formation of new steel market players, and promoting technological innovation of steel; An organic society needs to build a coordinated system of government, industry, university, research, financial services, build a mechanism that determines remuneration according to contributions, and respect labor, knowledge, talent and creativity.

Zhang Fucheng believes that the new technology in the steel industry is developing vigorously around three aspects: green and low-carbon metallurgical technology, intelligent digital development, and mechanical metallurgy regulation of steel organizational properties.

In terms of green low-carbon metallurgy technology, there are blast furnace carbon cycle low-carbon smelting technology, all-green hydrogen zero carbon emission ultra-short process metallurgy technology, molten salt electrolysis near zero carbon emission ultra-short process low-energy smelting technology, sintered flue gas carbon monoxide and nitric oxide intelligent emission reduction technology.

In the iron and steel industry intelligent digital development status, Zhang Fucheng said that at present, a number of iron and steel enterprises in the way of "software" to establish a digital virtual body exactly corresponding to the physical entity. By creating a virtual model of the steel production process to achieve real-time monitoring, predictive analysis and optimal control of the physical production system, it not only achieves cost reduction, efficiency improvement and safety improvement, but also promotes the intelligent and green development of the steel industry.

Zhang Fucheng introduced by example, in China, Shagang developed the whole process digital process simulation platform, realized the digitalization and intelligence of the whole process of steel, and shortened the product development cycle by more than 30%; Based on real-time monitoring and data analysis, Baosteel achieves on-line, real-time, indexation and quantitative diagnosis of furnace condition. Based on digital twin, industrial big data, etc., Hesteel carries out research on key technologies of intelligent manufacturing around the whole process of steel and achieves digital empowerment.

In foreign countries, ThyssenKrupp uses digital twin technology, combined with artificial intelligence and machine learning, to optimize energy consumption and production efficiency in the steel production process, while realizing remote monitoring and maintenance of production equipment; JFE intelligent slag removal system integrates machine vision, intelligent sensors, deep learning and automatic control technology, which can accurately identify the distribution of iron slag, and dynamically plan the slag removal path to achieve fully automated operation.

In addition, Zhang Fucheng said that the iron pre-process digital twin technology, continuous casting and rolling process digital twin technology, iron and steel material composition intelligent design technology, iron and steel organization performance intelligent prediction technology, iron and steel manufacturing enterprise gas pollutant emission intelligent detection technology, iron and steel manufacturing enterprise carbon emission intelligent detection technology, scrap intelligent quality inspection technology, based on machine vision scrap composition intelligence

Predictive technology and other steel data intelligence technology are contributing to the high-quality development of enterprises to reduce costs and increase efficiency.

"The ultimate goal of steel materials is excellent and stable performance, and its performance depends on the microstructure, mechanical metallurgy is an effective way to control the microstructure of steel materials, therefore, mechanical metallurgy is one of the only way to achieve high-end steel materials." Zhang Fucheng said that at present, the mechanical metallurgy control of steel microstructure properties technology mainly includes austenitic track steel manufacturing technology, bainite track steel manufacturing technology, pearlite track steel manufacturing technology, micro and nano twin structure low alloy steel manufacturing technology, multi-stage micro-structure low alloy steel manufacturing technology, multi-scale layered structural steel manufacturing technology.
