軋制H型鋼時，軋機作為機架使用，帶有兩個水平輥和兩個立輥，對軋件的腹板和翼緣四面碾壓。軋制普通型鋼時，軋機轉換成兩輥機架，即不帶立輥，只帶有兩個水平輥，對軋件進行軋制.

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.

軋機前后有對中導衛(wèi)的升降輥道，可保證軋件正確進入軋機。Therefore,alargeandmedium-sizedsteelmillisadoptedinthisform。三架軋機的輥系和軸承座同步更換，更換平臺在軋線外側，換輥時間長只用20min。傳動側的牌坊，通過液壓方式，由張力螺桿鎖定，操作側的牌坊為“可拉出”式，軋件導衛(wèi)固定在水平軋機的軸承座上。

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.

短應力線軋機具有如下優(yōu)點：

⑴容易實現(xiàn)負公差軋制，因為軋機的高剛度保證了產(chǎn)品的。

⑵可實現(xiàn)軋機左右兩個軸承的對稱調(diào)整，這對于穩(wěn)定軋制條件，提高作業(yè)率，節(jié)省檢修和更換導衛(wèi)、橫梁時間等具有重要意義。

Short stress line mill has the following advantages:

It is easy to realize negative tolerance rolling mill, because of the high rigidity to ensure high precision products.  

The symmetric adjustment can achieve about two rolling bearings, the stable rolling condition, improve operation efficiency, saving maintenance and replacement has important significance to guide and beam time etc.
