武钢一米七工程硅钢片厂,从日本引进了两台森吉米尔ZR22BS—42二十辊轧机,工作辊尺寸为φ63.5×1180毫米。由于冷轧硅钢的生产对尺寸精度及产品性能要求都很严,而且硅钢又脆又硬,工作条件恶劣,最大压力达400吨,最高轧制速度达450米/分,因此要求工作辊的材质要好,尺寸精度要高。工作辊是该轧机最重要的工具,消耗量大,以年产七万吨成品计算,年需要量600根, WISCO one meter seven engineering silicon steel sheet plant, from Japan introduced two Sendzimir ZR22BS-42 twenty-high rolling mill, work roll size φ63.5 × 1180 mm. As the production of cold-rolled silicon steel to the dimensional accuracy and product performance requirements are very strict, but also brittle and hard silicon steel, harsh working conditions, the maximum pressure of 400 tons, the maximum rolling speed of 450 m / min, so the work roll material Better, higher dimensional accuracy. Work roll is the most important tool for the mill, consume a large amount of annual output of 70,000 tons of finished products, the annual needs of 600,
