一、前言热轧硅钢在冷轧前,必须经过酸洗或退火过程,其目的是为了除磷和软化,改善其电磁性能。原日本新日铁公司为武钢硅钢片厂设计的酸洗机组,速度最大为33m/min,原材料厚度为2.0~2.3mm,宽800~1100mm,设备及工艺设计允许厚度为1.8~2.5mm的热轧带卷喂入。现在原料公称厚度为2.2mm,宽1050mm。根据生产运行的经验以及对设备能力的核算,认定该机组的电气设备及其供电
I. Introduction Hot-rolled silicon steel before cold-rolled, must be pickling or annealing process, its purpose is to remove phosphorus and softening to improve its electromagnetic properties. Japan’s Nippon Steel Company for WISCO steel plant designed pickling unit, the maximum speed of 33m / min, the raw material thickness of 2.0 ~ 2.3mm, width 800 ~ 1100mm, equipment and process design allows the thickness of 1.8 ~ 2.5mm heat Roll roll feeding. Nominal thickness of the material is now 2.2mm, width 1050mm. According to the experience of production and operation of the equipment capacity of the accounting, that the unit’s electrical equipment and power supply
