摘　　要：对比分析了高牌号无取向硅钢和碳钢热加工过程表面产生的氧化铁皮结构,在某硅钢常化酸洗生产线上,进行了一系列酸洗实验,研究了酸洗温度、酸液浓度、抛丸密度对酸洗时间和效果的影响,认为高牌号无取向硅钢表面氧化铁皮难于酸洗的原因是其特殊的结构造成的;得出了适用于高牌号无取向硅钢工业化生产的酸洗工艺参数。The oxide skin structures of high grade non-oriented silicon steel and carbon steel produced by hot rolling were comparative analyzed.A series of pickling experiments were carried out on a normalizing and pickling production line of silicon steel.The influences of pickling temperature,acid concentration and shot blasting on pickling time and effect were investigated.It is considered that the difficulty in pickling the oxide sheet on the surface of high grade non-oriented silicon steel was due to its special structure.The parameters of pickling process suitable for industrial production of high grade non-oriented silicon steel were given.
