摘　　要：对Si的质量分数在1.5%~2.0%的中牌号无取向硅钢,在不同卷取温度下氧化层对酸洗效果的影响进行了研究。结果表明:690℃高温卷取时,热轧板表层存在一层致密的氧化层,厚度在2~4μm,酸洗后,仍存在1~3μm氧化层;570℃低温卷取时,热轧板表层也存在一层致密的氧化层,厚度在2~4μm,但酸洗后,几乎不存在氧化层,且酸洗效率大幅提升。The effect of oxide layer at different coiling temperatures on pickling of non-oriented silicon steel with mass fraction of Si between 1.5%and 2.0%was studied.The results showed that:a dense oxide layer of 2-4μm thick was existed on the surface of the hot rolled plate when coiling temperature at 690℃,and after pickling the oxide layer was still 1-3μm thick;but when the coiling temperature at 570℃,the existing 2-4μm thick oxide layer on the surface of the hot rolled plate was almost disappeared after pickling,and the pickling efficiency was greatly improved.
