轧制H型钢时，***轧机作为***机架使用，带有两个水平辊和两个立辊，对轧件的腹板和翼缘四面碾压。轧制普通型钢时，***轧机转换成两辊机架，即不带立辊，只带有两个水平辊，对轧件进行轧制.

When rolling H steel, the universal mill is used as a universal frame, with two horizontal rolls and two vertical rolls, which are rolled over the web and flange of the rolled piece. When rolling ordinary steel, the universal rolling mill is converted into a two roll frame, that is, without a vertical roll, with only two horizontal rolls, rolling the rolled piece.

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.

短应力线轧机有什么特点？

短应力线轧机具有体积小、重量轻、轧机刚度大、轴承使用寿命长等优点。近年来该轧机在小型轧机上使用越来越广泛。随着短应力线轧机在线快速换辊装置的出现，使轧机***减少，导致其应用将会更普遍。

What are the characteristics of a short stress line mill?

Short stress line mill has the advantages of ***all volume, light weight, large rigidity of rolling mill and long service life of bearing. In recent years, the rolling mill has been used more and more widely in ***all rolling mill. With the emergence of on-line fast roll change device for short stress line rolling mill, the investment of rolling mill is reduced, and its application will be more common.
