保持工作辊的上辊和下辊相对于轧机中心线对称且在轴线方向上移动。这种的工作辊移动的设计，是用来改变工作辊和支撑辊的偏移需要大的移动量。这种大移动量的采用需要大量的改装费用，并且需要解决很多问题.
The upper and lower rolls of the work roll are symmetrical and move in the direction of the axis of the rolling mill. The movement of this work roll is designed to change the shift of work rolls and support rolls to require large amounts of movement. The use of this large shift of momentum requires a lot of modification costs, and many problems need to be solved.
在轧机设置了上轧辊动态轴向调整。轧机调零后，可以测量和存储上探头到上辊轴及下探头到下辊轴的距离。轧制过程中立辊如失去平衡而引起上辊或下辊的窜动，上辊会与下辊同步调整，从而保证上、下腹板对中并控制腹板和翼缘的尺寸。
There is a dynamic axial adjustment of the upper roll on the universal rolling mill. After the rolling mill is zero, the distance between the upper roll shaft and the lower probe can be measured and stored. During the rolling process, if the neutral rolls lose balance, the upper roller or the lower roll will move. The upper roller will synchronize with the lower roller, so as to ensure the upper and lower plate alignment and the dimensi of web and flange.
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.
