摘要
本文用L_(16)(4)~5正交表安排试验,所获数据用极差,图解、方差和回归计算方法找出该钢的最佳电磁搅拌参数900/1000 A/2.0 Hz/程序Ⅱ15 s-5 s-15s。经生产验证获得良好的冶金效果,船板钢铸坯中心线偏析指数降至1.0～1.5级。
L_(16)(4)~5 orthogonal method was used for optimization of electromagnetic stirring parameters.The optimal parameter of 900/1000 A/2.0 HZ/program Ⅱ 15″-5″-15″ have been found by means ofextreme difference,diagrams,square difference and regression,Good metallurgical results havebeen verified by application of these parameters in production practice.The index of central segre-gation in continuously cast slabs of ship plate steel reduced to grate 1.0～1.5.
