什么是铸造轧辊，铸造轧辊主要有哪些种类？

铸造轧辊是指将冶炼钢水或熔炼铁水直接浇注成型这一生产方式制造的轧辊种类。

铸造轧辊按材质又可分为铸钢轧辊和铸铁轧辊两类；按制造方法又可分为整体铸造轧辊和复合铸造轧辊两类。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method， it can also be divided into two types: integral casting roll and compound casting roll.

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，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，sleeper报价， 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，沈阳sleeper， while the weight of backup roll of wide plate mill has exceeded 200 t***. When selecting the roll， first， according to the requirements of the mill's basic strength for the roller， we select the main material for safety loading (various grades of cast iron， cast steel or forged steel，sleeper谁家好， etc.).

被轧制的钢种

被轧制的钢种是选择轧辊的关键因素，其抗变形能力随坯料化学成分不同而改变，主要表现在轧制的各阶段变形的负荷大小和变化。必须根据确定的强度和硬度选择轧辊。

Rolled steel

The rolled steel is the key factor to select the roll. Its deformation resistance varies with the chemical of the billet. It is mainly manifested in the load and change of deformation in each rolling stage. The roll must be selected according to the determined strength and hardness.
