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.

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。這種機架兼有開口式機架和閉口式機架的優(yōu)點，裝卸、換輥方便，制造容易，并有較高的剛度，故一般大中型的型鋼軋機都采用這種形式的機架。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.

軋制時毛坯的位置固定，因此不需設置側向支撐毛坯的導向尺?？傊?，它適用于軋制復雜外形結構，精度要求高，零件品種變換很多的情況。但其行程大小受到限制，所以，變形程度也受到影響，同時，板式軋機有空行程，故影響到生產率和變形程度都不能很大。

The of the blank is fixed during rolling, so there is no need to set the guide bar of the side supporting blank. In short, it is suitable for rolling complex shape structure with high accuracy and many varieties of parts. But the stroke size is limited, so the degree of deformation is also affected. At the same time, the plate mill has an empty travel, so the productivity and deformation can not be very large.
