初轧机、钢坯连轧机、大型型钢和轨梁轧机、热轧板带钢轧机破鳞和轧边机、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, 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.
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.
当轧制其它型材时，可以用水平机架更换***机架。水平机架的轧辊有很深的孔型，而***机架没有。
较大直径的水平轧辊确定型钢的的形状，而较小直径的一对立辊用于轧制边部。当坯料穿过传统机架和***机架精轧轧辊时，可以获得很好的表面光洁度和尺寸公差。
When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.
Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with ***aller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
