上轧辊为液压式平衡装置，电动压下，压下量480mm，压下速度60mm／s，正常轧制时下辊固定，上辊压下。换品种和使用较小直径的轧辊时，下轧辊用垫片组调节其水平度.
The upper roller is the hydraulic balance device, the electric press down, the press down 480mm, the down speed 60mm / s, the normal rolling roll fixed and the upper roller. When changing varieties and using ***aller diameter rolls, the lower roll can be adjusted by the gasket group.
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, that is, without a vertical roll, with only two horizontal rolls, rolling the rolled piece.
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.
