研究了Cu2S抑制剂在薄板坯连铸连轧流程生产取向硅钢全流程中的析出特点。结果表明:典型成分取向硅钢主抑制剂Cu2S在全工序进程中析出粒子呈不断长大的趋势,粒子分布密度与体积分数在高温退火前也不断增加,高温退火净化后,剩余粒子变大,分布密度大大降低,对应体积分数也降低。 The precipitation characteristics of Cu2S inhibitor in the process of producing oriented silicon steel by thin slab continuous casting and rolling process were studied. The results show that Cu2S, a typical inhibitor of oriented silicon steel, tends to grow in the whole process. The particle distribution density and volume fraction also increase before high temperature annealing. After annealing at high temperature, the residual particles become larger and larger Decreased density, the corresponding volume fraction is also reduced.
