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.
短应力线轧机具有如下优点：
⑴容易实现负公差轧制，因为轧机的高刚度保证了产品的。
⑵可实现轧机左右两个轴承的对称调整，这对于稳定轧制条件，提高作业率，节省检修和更换导卫、横梁时间等具有重要意义。
Short stress line mill has the following advantages:
It is easy to realize negative tolerance rolling mill, because of the high rigidity to ensure high precision products.
The symmetric adjustment can achieve about two rolling bearings, the stable rolling condition, improve operation efficiency, s***ing maintenance and replacement has important significance to guide and beam time etc.
按轧制品种、轧机型式和公称尺寸来命名。“公称尺寸”的原则对型材轧机而言，是以齿轮座人字齿轮节圆直径命名。
It is named according to the varieties of rolling, the type of rolling mill and the nominal size. The principle of "nominal size"
For rolling mills, they are named after the gear ring and the pitch diameter of the herringbone gear.
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.
