冷轧板带轧辊的辊身呈微凸，当它受力弯曲时可保证良好扳形；型钢轧机轧辊的辊身上有轧槽，根据型钢轧制工艺要求，安排孔型。钢管轧制中采用斜轧原理轧制的轧辊有圆锥形、腰鼓形或盘形。

The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, it can ensure good shape. There are grooves on the roller body of the section mill roll, and the pass is arranged according to the rolling re of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.

轧辊的品种和制造工艺随冶金技术的进步和轧钢设备的演变而不断发展。中世纪轧制软的有色金属时使用强度低的灰铸铁轧辊。18世纪中叶英国掌握了轧制钢板用的冷硬铸铁轧辊的生产技术。

The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling e The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.

既避免机械加工，又无补焊热应力热影响，修正厚度也不受捆绑，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 avoid 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 available, so as to ensure a hundred percent contact and cooperation of the corrected parts.
