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。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。四棍軋機的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。

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.

機架是軋鋼機的主要部件，它在軋鋼過程中承擔金屬變形給予的負荷。因此要求機架有足夠的強度和剛度，以保證設備安全和產(chǎn)品質(zhì)量。型鋼軋機的機架形式較多，常見的機架形式有開口式機架、閉口式機架和半閉口式機架3種。

The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to have sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.

軋機的輥系在換輥前可以預安裝并調(diào)整好，軋機停車后只需較短時間即可換上新輥系。而新輥系經(jīng)少量試軋后即能軋出合格產(chǎn)品。因此這種軋機可調(diào)性能好，成材率高。

短應力線軋機可制成二輥式、三輥式或四輥式多種形式的軋機。在型鋼、線材和板帶鋼生產(chǎn)中部有應用。

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