针对某钢厂新建板坯连铸机,采用板坯连铸浇铸过程静态仿真软件CCPS OFFLINE中的二冷优化设计模块,基于合理制定的目标表面温度曲线进行了二冷系统的优化设计,通过反向仿真计算获得了不同铸坯厚度规格和钢种组别所对应的二冷水表,并对一些重要的二冷参数进行了详细分析,包括比水量、回路水量分配比例以及喷嘴的流量范围和调节倍率.该方法具有可靠的理论基础和良好的实用价值,可广泛地应用于板坯连铸二次冷却系统的设计工作之中.
Aiming at the new slab caster in a steel mill, the second cooling optimization design module in the static simulation software CCPS OFFLINE of slab continuous casting and casting was adopted. The second cooling system was optimized based on the reasonable target surface temperature curve. The secondary chilled water meters with different slab thickness specifications and steel groups were obtained from the simulation. Some important secondary cooling parameters were analyzed in detail, including the ratio of specific water, the proportion of circulating water flow and the flow range and adjustment of the nozzle This method has a reliable theoretical basis and good practical value, which can be widely used in the design of secondary cooling system of slab continuous casting.
