轧制H型钢时，轧机作为机架使用，带有两个水平辊和两个立辊，对轧件的腹板和翼缘四面碾压。轧制普通型钢时，轧机转换成两辊机架，即不带立辊，只带有两个水平辊，对轧件进行轧制.

When rolling H steel， the universal mill is used as a universal frame， with two horizontal rolls and two vertical rolls， which are rolled over the web and flange of the rolled piece. When rolling ordinary steel， the universal rolling mill is converted into a two roll frame，大庆rolling mill， that is， without a vertical roll， with only two horizontal rolls， rolling the rolled piece.

驱动电机斜置在锯机底座上，通过伞齿轮及主传动轴带动锯片，锯片由液压装置锁紧在传动轴上。锯片进锯由液压驱动，进锯速度根据锯切阻力由比例阀调节。当轧件断面较大、锯切阻力高时，进锯速度慢，反之，进锯速度块。

The driving motor is inclined on the base of the saw machine， and the saw blade is driven through the bevel gear and the main drive shaft，420rolling mill， and the saw blade is locked on the drive shaft by the hydraulic device. The sawing saw is driven by hydraulic pressure， and the speed of the saw is adjusted by the proportional valve according to the cutting resistance. When the section of the rolled piece is large and the cutting resistance is high， the speed of the saw is slow， and conversely， the speed block of the saw.

楔横轧机类型有辊式、板式和单辊弧式楔横轧机。三种类型的楔横轧机相比，板式楔横轧机模具制造较为简单，模具的调整比较容易，750rolling mill，因而轧件的精度较高，并且工艺可靠.

The cross wedge rolling mill has roller type， plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill， the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy， so the precision of the workpiece is high and the process is reliable.
