既避免机械加工，又无补焊热应力热影响，修正厚度也不受***，一起产品所具有的耐磨性及金属材料不具备的退让性，确保修正部位的接触协作。

Not only to ***oid mechanical processing, but also to weld hot stress and heat, the correction thickness is not bound, and the wear resistance of a product and the non - concession of metal materials are not ***ailable, so as to ensure a hundred percent contact and cooperation of the corrected parts.

初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机破鳞和轧边机、型钢轧机的轧边机，还有小型型钢、线棒材轧机的粗轧机架等轧机使用的轧辊，大多采用整体铸造方法生产，这类轧辊使用层较厚，孔型较深。

The rolling mill of rolling mill, billet rolling mill, large type steel and rail beam mill, hot rolled strip mill break scale, rolling edge mill, type steel universal mill, and rolling mill used in ***all steel and wire rod mill are mostly produced by the whole casting method, which is thicker and deeper.
