初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机*鳞和轧边机、型钢轧机的轧边机，还有小型型钢、线棒材轧机的粗轧机架等轧机使用的轧辊，大多采用整体铸造方法生产，这类轧辊使用层较厚，孔型较深。

The rolling mill of rolling mill，圣霖国际吊车轨价格， billet rolling mill， large type steel and rail beam mill， hot rolled strip mill break scale， rolling edge mill， type steel universal mill， and rolling mill used in *all steel and wire rod mill are mostly produced by the whole casting method， which is thicker and deeper.

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，圣霖国际吊车轨，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，圣霖国际吊车轨价格， 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.

19世纪下半叶欧洲炼钢技术的进步要求轧制更大吨位的钢锭，无论是灰铸铁或冷硬铸铁轧辊的强度均已不能满足要求。含碳量为0.4%～0.6%普通铸钢轧辊相应诞生。重型锻压设备的出现更使这种成分的锻造轧辊的强韧性得到进一步****。

In the second half of the nineteenth Century， the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon conte*f 0.4% to 0.6% is born accordingly. The emergence of he*y forging equipment makes the strength and toughness of the forging roll of this component further improved.
