輥系快速整體更換不需吊車，采甩軋輥牽引小車和橫移臺(tái)車結(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.

軋機(jī)前后有對(duì)中導(dǎo)衛(wèi)的升降輥道，可保證軋件正確進(jìn)入軋機(jī)。三架軋機(jī)的輥系和軸承座同步更換，更換平臺(tái)在軋線外側(cè)，換輥時(shí)間長只用20min。這種機(jī)架兼有開口式機(jī)架和閉口式機(jī)架的優(yōu)點(diǎn)，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(jī)都采用這種形式的機(jī)架。傳動(dòng)側(cè)的牌坊，通過液壓方式，由張力螺桿鎖定，操作側(cè)的牌坊為“可拉出”式，軋件導(dǎo)衛(wèi)固定在水平軋機(jī)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(shí)毛坯的位置固定，因此不需設(shè)置側(cè)向支撐毛坯的導(dǎo)向尺?？傊?，它適用于軋制復(fù)雜外形結(jié)構(gòu)，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(shí)，板式軋機(jī)有空行程，故影響到生產(chǎn)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.
