通常对粗轧辊以强度、抗热裂为主要要求；小型20辊轧机的工作轧辊重仅 100克左右，而宽厚板轧机的支承辊重量已超过200吨。选用轧辊时首先根据轧机对轧辊的基本强度要求，sleeper谁家好，选定安全承载的主体材料（各种级别的铸铁、铸钢或锻钢等）。
Usually， the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of **all 20 high mill is only 100 grams， while the weight of backup roll of wide plate mill has exceeded 200 t. When selecting the roll， first，白山sleeper， according to the requirements of the mill"s basic strength for the roller，sleeper报价， we select the main material for safety loading (various grades of cast iron， cast steel or forged steel， etc.).
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，sleeper哪家好，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 requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.
由于轧制过程是连续的过程，因此操作人员需要不断检测轧辊状况，使生产出来的产品满足用户对更严格的公差和表面质量的要求。
As the rolling process is a continuous process， the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface quality requirements of the products produced.
