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.
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，辽源rolling mill，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，450rolling mill， 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.
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，500rolling mill，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.
