軋機(jī)前后有對中導(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，更換平臺在軋線外側(cè)，換輥時(shí)間長只用20min。當(dāng)厚度偏差增大（在板寬方向上厚度不同）導(dǎo)致在材料設(shè)計(jì)后產(chǎn)品損失中應(yīng)考慮增加板厚邊緣。傳動側(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.

半閉口式機(jī)架是機(jī)架與機(jī)架蓋之間采用斜楔連接的一種機(jī)架。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。

A semi closed frame is a frame with a wedge between the frame and the frame cover. The rack has the advantages of open frame and closed frame. It has the advantages of loading and unloading, easy roll changing, easy manufacture and high rigidity. Therefore, a large and medium-sized steel mill is adopted in this form.

軋機(jī)專業(yè)廠家介紹，其實(shí)從實(shí)際生產(chǎn)作業(yè)來看，關(guān)于冷軋機(jī)的安全生產(chǎn)主要包括三個方面，分別為：定期檢修、日常安全操作以及日常的培訓(xùn)管理等。

In fact, from the actual production operation, the safety production of the cold rolling mill mainly includes three aspects, which are the regular maintenance, the daily safety operation and the daily training etc.
