420rolling mill价格合理 圣霖国际诚实守信

轧机前后有对中导卫的升降辊道，可保证轧件正确进入轧机。三架轧机的辊系和轴承座同步更换，更换平台在轧线外侧，换辊时间***长只用20min。H型钢在冷床上直立冷却后，由辊道送至变节距辊式矫直机进行长尺矫直，经成排台架成排后，由冷锯机切成6～24m定尺。传动侧的牌坊，通过液压方式，由张力螺杆锁定，操作侧的牌坊为“可拉出”式，轧件导卫固定在水平轧机的轴承座上。

A lift roller of the guide in the time before and after the mill, rolling mill can ensure the correct entering. The roll system of three rolling mills is replaced synchronously with the bearing seat, and the replacement platform is on the outside of the rolling line. The longest time for changing the roll is only 20min. The movable side arch is locked by tension screw, and the operation side arch is "pull-out" type, and the rolling guide is fixed on the bearing seat of the horizontal rolling mill.

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.

据说在14世纪欧洲就有轧机，但有记载的是1480年意大利人达·芬奇（Leonardo da Vinci）设计出轧机的草图。1553年法国人布律列尔(Brulier)轧制出金和银板材,用以制造钱币。此后在西班牙、比利时和英国相继出现轧机。

It is said that there are rolling mills in Europe in the fourteenth Century, but it is recorded that in 1480, Leonardo Da Vinci (Italian Italian designer Da Finch) designed the draft for rolling mills. In 1553 the French law Adler cloth (Brulier) rolled gold and silver plate, used in the manufacture of coins. Since then, rolling mills h***e been rolled out in Spain, Belgium and Britain.
