Bar multi-cutting low-temperature finishing technology in actual production will come with some troubles, like as the head deformation of the rolled parts; multi-line cutting water cooling temperature control is not uniform and others. In 2022, Metallurgical Jingcheng Engineering Technology Co., Ltd. and Beijing Jianlong Heavy Industry Co., Ltd. cooperated to develop high-precision temperature control and slitting rolling technology, intelligent multi-wire control rolling and post-rolling classification control cooling technology of hot rolled steel bar, which realized accurate temperature control of each line rolling and increased production stability.
CMC Jingcheng independent develops stainless steel ring solution treatment furnace, overcomes the technical problem of the "solution treatment grain size uniformity". The annular solution treatment furnace adopts the flexible control mode of "proportional + pulse", and the treatment temperature can be achieved up to 1200℃, and the performance indexes such as grain size and intergranular corrosion resistance of the coil after solution treatment can reach high standards, and the grain size difference at each point is less than two levels, and the material organization and composition are uniform, eliminating the material Processing hardness.
On September 15, 2022, South China Metallurgical Corporation officially released the overall solution of intelligent Blast Furnace. Based on the blast furnace centralized control center, through a number of intelligent technologies, the intelligent blast furnace can dynamically display the evolution of airflow, charge, furnace shape and safety form inside the furnace, present the economic index of production operation and safety status of equipment and personnel in multiple dimensions, and complete comprehensive monitoring, evaluation and diagnosis of blast furnace production. The safety, stability and efficiency of the intelligent blast furnace are significantly improved compared with ordinary blast furnaces, meanwhile can reduce energy consumption and CO2 emissions clearly.
In April 2022, the intelligent Ironmaking Center project of Anshan Iron and Steel Company, which was designed and built by Anshan Iron and Steel Group Engineering and Technology Company independently and under general contract, was successfully connected to the grid. This project is the world's largest pre-iron integrated intelligent ironmaking center, which is an integrated smart centralized control system with cross-process, cross-region and cross-interface. It breaks the data barriers among processes, realizes the collaborative production and barrier-free communication among coking, sintering, pellet and iron-making processes,and realizes the transformation from empirical management to digitalized and lean management.
The Cold Rolling Integrated Control Platform developed by CMLS, which has all five core capabilities of Industrial Internet, including ubiquitous perception, intelligent decision-making, agile response, global coordination and dynamic optimization, it can realize the integration of production control while continuously optimizing the process and production level through data analysis, it can realize the coordination of production and operation; the integration of product value flow, while it can open up the whole process of product from raw material transportation, manufacturing and service. The integration of product value stream, which opens up the whole process of products from raw material transportation, manufacturing and service, eliminates process waste to achieve overall optimization of product value stream and improve economic efficiency; the integration of the whole life cycle of assets is to achieve optimization of the whole life cycle from plant design, construction, commissioning, operation and maintenance.
