轧辊是轧机的重要部件，按照轧机类型可分为领带轧机轧辊、型钢轮机扎辊和钢管轧机轧辊三大类。

板带轧机轧辊的辊身呈圆柱形，热乾板带轧辊的辊身微凹，当受热膨胀时，可保持较好的扳形。

Roll is an important part of the rolling mill. According to the type of rolling mill, it can be divided into three types: the tie mill roll, the type steel turbine ligation roll and the steel tube rolling mill roll.

The roll body of a strip rolling mill is cylindrical, and the roll body of the hot dry plate is slightly conc***e. When the heat is expanded, it can maintain a better shape.

按轧辊材质分有钢轧辊、铸铁轧辊、硬质合金轧辊、陶瓷轧辊等；按制造方法分有铸造轧辊、锻造轧辊、堆焊轧辊、镶套轧辊等；按所轧钢材状态分有热轧辊、冷轧辊。各种分类可以相应组合而使轧辊有更明确的含义，如热轧带钢用离心铸造高铬铸铁工作辊。

According to the roller material, there are steel rolls, cast iron rolls, hard alloy rolls, ceramic rollers, etc. according to the manufacturing method, there are casting rolls, forging rolls, hardfacing rolls, inlaid rolls and so on. According to the rolled steel status, there are hot rollers and cold rollers. Various classificati*** can be combined to make the roll more explicit, such as the casting of high chromium cast iron working roll for hot rolled strip.

线材轧机拥有粗轧机架和与小型型材轧机类似的中间机架。与两线轧制的小型型材轧机相比，这些轧机一般被设计成可以进行高达4线的同时轧制的切分轧制。然而，目前的发展趋势是采用单线的高速轧制。

The wire mill has a roughing mill stand and an intermediate rack similar to a ***all section mill. Compared with the two section rolling mill, these mills are generally designed for rolling up to 4 lines at the same time. However, the current development trend is single line high-speed rolling.
