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(jié)合的換輥方式，導(dǎo)衛(wèi)橫梁安裝在軋機軸承座上，更換軋輥時,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.

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(zhuǎn)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.

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。這類設(shè)備的主要優(yōu)點是相對剛度較大，壓下量大、軋延力小，可軋制較薄的板材，也包括有可逆和連軋兩種。

The working roll diameter of the four bar mill is small, and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness, large reduction, low rolling force, thin rolled sheets, and reversible and continuous rolling two.
