保持工作輥的上輥和下輥相對(duì)于軋機(jī)中心線對(duì)稱(chēng)且在軸線方向上移動(dòng)。這種的工作輥移動(dòng)的設(shè)計(jì)，是用來(lái)改變工作輥和支撐輥的偏移需要大的移動(dòng)量。這種大移動(dòng)量的采用需要大量的改裝費(fèi)用，并且需要解決很多問(wèn)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(chē)，采甩軋輥牽引小車(chē)和橫移臺(tái)車(chē)結(jié)合的換輥方式，導(dǎo)衛(wèi)橫梁安裝在軋機(jī)軸承座上，更換軋輥時(shí),導(dǎo)衛(wèi)及橫梁隨輥系整套從牌坊窗口中拖出，一次換輥時(shí)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(yīng)力線軋機(jī)有什么特點(diǎn)？

短應(yīng)力線軋機(jī)具有體積小、重量輕、軋機(jī)剛度大、軸承使用壽命長(zhǎng)等優(yōu)點(diǎn)。近年來(lái)該軋機(jī)在小型軋機(jī)上使用越來(lái)越廣泛。隨著短應(yīng)力線軋機(jī)在線快速換輥裝置的出現(xiàn)，使軋機(jī)投資減少，導(dǎo)致其應(yīng)用將會(huì)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.
