轧辊的分类方法有多种，主要有：（1）按产品类型分有带钢轧辊、型钢轧辊、线材轧辊等；（2）按轧辊在轧机系列中的位置分有开坯辊、粗轧辊、精轧辊等；（3）按轧辊功能分有*鳞辊、穿孔辊、平整辊等。
There are many classification methods like roller are: (1) according to the type of product with strip roller， steel roller， wire roller; (2) according to the roll in rolling mill series in the of divided blooming rolls， roughing roll， finishing roll; (3) according to the function of a roller descaling Kong Gun，通化crane rail， wearing roller， flat roll etc.
轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，并通过袖承座和压下装置把轧制力传给机架。铂头和连接轴相连接，crane rail生产，传递轧制扭矩。轴头有三种主要形式；梅花轴头、万向轴头、带键槽的或圆柱形轴头。
The roll is of two parts of the roller body，crane rail价格， the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum， a universal shaft， or a cylindrical shaft with a keyway.
既避免机械加工，又无补焊热应力热影响，修正厚度也不受**，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 **oid 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 **ailable， so as to ensure a hundred percent contact and cooperation of the corrected parts.
