What are the common methods to optimize the continuous casting process

With the continuous development of technology and continuous casting process, the whole industry has made rapid progress. At present, it has developed from local relay logic control to distributed control system. In order to make the steelmaking process more efficient and refined, most of them have taken some measures.

1. Collaborative optimization of steelmaking continuous casting process

The copper mould tube manufacturer introduces the comprehensive integration of accurate control technology for smelting high-quality steel converter end point, lean control technology for continuous casting solidification and cooling process, coordination and control technology for process operation in steelmaking continuous casting process, fine production planning and scheduling technology, cooperation between production scheduling model and process process model, and interface technology between various technologies and MES, Form a system technology system and integrated solution supported by production process control, process operation coordination control and collaborative optimization of production planning and scheduling.

2. Optimize the combined blowing converter process and increase the bottom blowing intensity

The stable and efficient operation of the bottom blowing system of the combined blowing converter directly affects the comprehensive level of converter production and organization. Major scientific research institutions and production plants are constantly optimizing and improving the composite blowing process and related supporting technologies.

Optimization method of continuous casting process: by developing a new type of converter bottom blowing tuyere, optimizing the masonry structure of converter bottom refractory, updating the maintenance mode of converter bottom blowing tuyere, and implementing the slag hanging technology at the bottom blowing tuyere, the combined blowing effect in the later stage of furnace service is significantly improved, the combined blowing proportion of converter is increased from 79.2% to 100%, and the carbon and oxygen product of converter blowing is reduced from 0.0033 to 0.0023.

3. Improve the control level of inclusions and improve the quality of iron and steel

Based on the original protective pouring, it is proposed to plug asbestos at the gap between the ladle cover, block the ladle cover opening, appropriately increase the argon blowing pressure and standardize the on-site operation during the pouring process from the ladle to the tundish, so as to maintain the composition of liquid steel (calcium content, magnesium content, total aluminum and acid soluble aluminum) at a relatively stable level.

Continuous casting process optimization can improve labor conditions and improve labor productivity. Continuous casting has a high degree of automation and saves a lot of manpower. Manual operations are interspersed from the whole mold, ingot casting, demoulding and initial binding of ingots. The degree of automation is low and the working conditions of workers are poor.
