The new trend of "steel demand" promotes the steel industry to improve quality and efficiency

"In the steel production process, the short-flow process of 'scrap + electric furnace' is one of the most effective ways to reduce carbon." Tian Yong, deputy general manager of Angang Group, said that in addition, replacing coke with hydrogen as the main fuel in the traditional long-process process can also effectively reduce carbon.

According to statistics, by the end of September, a total of 96 steel enterprises had completed ultra-low emission transformation and evaluation and monitoring, involving crude steel production capacity of about 453 million tons.

-- Digitalization empowers the entire steel manufacturing process. Bring together 26 production lines, integrate 210 sets of related systems, and collect more than one million points of data... The digital twin intelligent operation system created by Nanjing Iron and Steel Co., LTD., for tens of millions of tons of steel enterprises, restores the real production line to achieve digital production and visual manufacturing.

"Through intelligent algorithms and system models, the system can shorten the development cycle, reduce energy consumption per ton of steel, improve the efficiency of industrial chain collaboration, and reduce the cost of industrial chain cooperation." Nanjing Iron and Steel Co., Ltd. executive vice president Xu Xiaochun said.

At present, steel enterprises are actively promoting the deep integration of digitalization, intelligence and other new generation information and communication technologies with the entire process of steel manufacturing. Csa data show that the application density of robots in the steel industry has reached 54 units (sets) / 10,000 people, 90% of steel enterprises have established a production and manufacturing execution and energy control system, and enterprises above 5 million tons have basically established a control connection system.

"In recent years, we have comprehensively implemented supply-side structural reform in the steel industry, focused on resolving excess capacity, and vigorously promoted green and low-carbon transformation, laying a solid foundation for realizing the modernization of the steel industry and promoting the high-quality development of China's economy. China's steel industry has shown a good development pattern." Vice Minister of industry and Information Technology Wang Jiangping said.
