550rolling mill-圣霖国际【用心服务】

还有三辊轧机，轧机**厂家介绍，这种轧机由于本身的优势并不突出，所以使用的比较少。那么，四辊轧机具有怎样的特点恩？这种类型的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。其的优点在于相对刚度高、压下量大、轧延力小，比较适合轧制较薄的板材。

There are three-high mill， mill professional manufacturers ， this kind of mill because of its advantages are not prominent， so the use of less. So， what are the characteristics of the four high rolling mill? The working roll diameter of this type of mill is **aller， the rolling torque is tran**itted，800rolling mill， and the rolling pressure is borne by the backup roll with larger diameter. Its advantages are high relative stiffness， large reduction and **all rolling force，绥化rolling mill， so it is suitable for rolling thin sheets.

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。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.

轧机的辊系在换辊前可以预安装并调整好，轧机停车后只需较短时间即可换上新辊系。而新辊系经少量试轧后即能轧出合格产品。因此这种轧机可调性能好，成材率高。

短应力线轧机可制成二辊式、三辊式或四辊式多种形式的轧机。在型钢、线材和板带钢生产中部有应用。

The roll system of rolling mill can be pre installed and adjusted before changing the roll. After the rolling mill ， it only needs a short time to replace the new roll system. The new roll system can be rolled out of the qualified product after a **all amount of test rolling. Therefore， this kind of rolling mill has good adjustable performance and high yield.  

The short stress line mill can be made into two - roll， three - roll， or four - roll type rolling mills. It is applied in the middle part of steel， wire and strip steel.
