Capacity analysis of steelmaking-continuous casting section based on different products mixes

Capacity is an important technical and economic indicator to evaluate the production and operating state of steel plants. Aiming at the problems about the capacity of steelmaking-continuous casting section, firstly, the operation time of steelmaking, refining and continuous casting process for different steel grades is found out by resolving the production process of a BOF special steel plant. Then, the bottleneck process under different production mixes is found by discussing the relation among the productive capacity of steelmaking-continuous casting system, the capacity of different processes and the products mixes. Finally, the improvement measures for promoting the capacity are proposed aiming at breaking through the restriction of bottleneck process. A general method to research on the capacity of steelmaking-continuous casting section is developed, which helps to determine reasonable index of products mix and give full play to the capacity of steelmaking-continuous casting section.
