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，650rolling mill，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 small 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，520rolling mill， or four - roll type rolling mills. It is applied in the middle part of steel， wire and strip steel.

在经过改进之后，目前的轧机设备采用的是被动一轧一拖式生产方式，可以实现两道轧制成型，不仅解决了速度配合问题，而且改变了传统的四道轧制方式，生产效率明显提高。

After the improvement， the current? mill equipment adopts a passive one rolling and towing mode of production， which can realize two rolling forming. It not only solves the problem of speed matching， but also changes the traditional four way rolling method，大连rolling mill， and the production efficiency is? improved.

轧制时毛坯的位置固定，因此不需设置侧向支撑毛坯的导向尺。总之，它适用于轧制复杂外形结构，精度要求高，零件品种变换很多的情况。但其行程大小受到限制，850rolling mill，所以，变形程度也受到影响，同时，板式轧机有空行程，故影响到生产率和变形程度都不能很大。

The of the blank is fixed during rolling， so there is no need to set the guide bar of the side supporting blank. In short， it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited， so the degree of deformation is also affected. At the same time， the plate mill has an empty trel， so the productivity and deformation can not be very large.
