摘要
研究了某钢厂方坯连铸机钢水过热度、拉速及二冷比水量对82B铸坯内部质量的影响。得出生产中最优参数后,结合射钉试验确定末端电磁搅拌装置的位置。保持工艺参数稳定后,确定最佳电磁搅拌参数。经过改造与调整后铸坯中心偏析和缩孔明显改善,铸坯内部质量相应提高。
An effect of how much the superheat, casting speed, secondary cooling specific water flow rate of a billet casting machine affects on internal quality of 82B billet in one steel-making plant. Optimum parameters in production are obtained, while it considers the pin-shooting test to determine the end position of the final elec- tromagnetic stirring device. The optimal parameters of electromagnetic stirring steady process condition come af- ter the steady process condition. It reduces the central segregation and shrinkage after revamping, and improves the internal quality of the billet.
