保持工作輥的上輥和下輥相對于軋機中心線對稱且在軸線方向上移動。這種的工作輥移動的設計，是用來改變工作輥和支撐輥的偏移需要大的移動量。這種大移動量的采用需要大量的改裝費用，并且需要解決很多問題.

The upper and lower rolls of the work roll are symmetrical and move in the direction of the axis of the rolling mill. The movement of this work roll is designed to change the shift of work rolls and support rolls to require large amounts of movement. The use of this large shift of momentum requires a lot of modification costs, and many problems need to be solved.

輥系快速整體更換不需吊車，采甩軋輥牽引小車和橫移臺車結合的換輥方式，導衛(wèi)橫梁安裝在軋機軸承座上，更換軋輥時,導衛(wèi)及橫梁隨輥系整套從牌坊窗口中拖出，一次換輥時間僅為20min.

You don't need to replace the whole fast roller roller way for mining crane, trolley and swing roller traversing trolley with the guide beam is installed on the bearing seat of rolling mill, roll changing, guide and beam with roll set pulled from the housing window, a roll change time is only 20min.

短應力線軋機有什么特點？

短應力線軋機具有體積小、重量輕、軋機剛度大、軸承使用壽命長等優(yōu)點。近年來該軋機在小型軋機上使用越來越廣泛。隨著短應力線軋機在線快速換輥裝置的出現(xiàn)，使軋機投資減少，導致其應用將會更普遍。

What are the characteristics of a short stress line mill?  

Short stress line mill has the advantages of small 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 small 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.
