基于产品结构的炼钢-连铸区段产能解析

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

生产能力是衡量钢厂生产运营状况的重要技术经济指标。通过对国内某全连铸转炉特殊钢厂生产过程的解析,确立了不同钢种在炼钢、精炼、连铸3个主体工序的运行时间参数。在此基础上探讨炼钢-连铸区段中各工序产能与生产产品结构、炼钢-连铸区段的系统产能与工序产能的关系,分析不同产品结构下制约系统产能的瓶颈工序,对此提出提高系统产能的相应改进措施。形成了具有普适性的炼钢-连铸区段产能研究方法,为钢厂确定合理的产能和产品结构指标以及充分发挥整个炼钢-连铸区段系统的生产能力提供一定指导和理论依据。

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.
