本文借助已建立的传热计算仿真模型，对连铸机的现行工艺进行了模拟计算分析，考察了影响连铸机最佳拉速的限制性环节，在此基础上，对不同拉速和过热度进行了传热模拟计算，找到了连铸机工况最佳拉速与中间包钢水过热度的关系；以凝固传热的冶金准则为约束条件，设定铸坯表面目标温度，采用单值搜索法，找到了连铸机二冷区的合理给水量，建立了二冷配水优化模型
In this paper, with the established simulation model of heat transfer calculation, the current technology of continuous casting machine is simulated and analyzed, the limiting factors that affect the optimum drawing speed of continuous casting machine are investigated. On the basis of this, The heat transfer simulation was carried out and the relationship between the optimum drawing speed and the superheat of the tundish was found. Based on the metallurgical rules of the solidification and heat transfer, the target temperature of the slab surface was set, Value search method to find a reasonable secondary water supply area of continuous casting machine, the establishment of a secondary cooling water distribution optimization model
