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.

机架是轧钢机的主要部件，它在轧钢过程中承担金属变形给予的负荷。因此要求机架有足够的强度和刚度，以保证设备安全和产品质量。型钢轧机的机架形式较多，常见的机架形式有开口式机架、闭口式机架和半闭口式机架3种。

The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to h***e sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.

四棍轧机的工作辊直径较小，传递轧制力矩，轧延压力由直径较大的支承辊承受。这类设备的主要优点是相对刚度较大，压下量大、轧延力小，可轧制较薄的板材，也包括有可逆和连轧两种。

The working roll diameter of the four bar mill is ***all, and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness, large reduction, low rolling force, thin rolled sheets, and reversible and continuous rolling two.

五辊轧机，轧机***厂家介绍，这种轧机也可以进行更为细致的分类，其中一种可以可以用于轧制比较难变形的金属和合金带材，另外一种常用于轧制厚度公差很小的不锈钢、碳钢和有色金属带材。

Five-high mill, mill professional manufacturers, this kind of mill can also be more detailed classification, one can be used for rolling more difficult to deform metal and alloy strips, another is often used for rolling thin tolerance of stainless steel, carbon steel and non-ferrous metal strips.
