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**过200吨。选用轧辊时首先根据轧机对轧辊的基本强度要求，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 small 20 high mill is only 100 grams， while the weight of backup roll of wide plate mill has exceeded 200 tons. When selecting the roll，sleeper厂家， first， according to the requirements of the mill's basic strength for the roller，sleeper生产厂家， we select the main material for safety loading (various grades of cast iron， cast steel or forged steel， etc.).

硬质合金辊环广泛应用于高速线材轧机的精轧机架，sleeper哪家好，以及部分高速线材轧机的预精轧机架和棒材轧机的精轧机架。硬质合金轧辊的优点是硬度高、耐磨性好，黑龙江sleeper，单槽轧钢量可以达到高速钢轧辊的两倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill， as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance， and the amount of single groove rolled steel can reach two times of the high speed steel roll.

这些应力沿辊身的散布是不均匀的、不断改变的，其原因不只有规划要素，还有轧辊在运用中磨损、温度和辊形的不断改变。

The dispersion of these stresses along the roll is uneven and constantly changing， and the reasons are not only the planning elements， but also the constant change of wear， temperature and roll shape in the use of the rolls.
