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, 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.

在锻造和轧制生产中，钢坯一般在完全燃烧火焰的氧化气氛中加热。采用不完全燃烧的还原性火焰（即“自身保护气氛”）来直接加热金属，可以达到无氧化或少氧化的目的。这种加热方式称为明火式或敞焰式无氧化加热，成功地应用于转底式加热炉和室式加热炉。

In forging and rolling production, billets are usually heated in the combustion atmosphere of complete combustion flame. The direct combustion of metal can be achieved by the incomplete combustion of reduced flame (i.e., the "self protective atmosphere"), which can achieve the of no oxidation or less oxidation. This heating method is called open flame or open flame oxidation free heating, which has been successfully applied to rotary hearth furnace and chamber heating furnace.

楔横轧工艺的基本原理是，将加热后的棒材送入两个同向旋转的带有楔性凸起的模具中间，棒材在模具的带动下，作与模具反向的回转运动，同时材料发生径向压缩变形和轴向延伸变形，从而成形阶梯轴类零件。

The basic principle of the cross wedge rolling process is to send the heated bar into the middle of two same revolving moulds with wedge-shaped protrusi. The rod is driven by the mold to make the reverse rotation movement with the mold. At the same time, the material has radial compression deformation and axial extension deformation, thus forming a staircase type part.

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，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.
