使用熱軋的第二個(gè)優(yōu)點(diǎn)就在于其可以適當(dāng)?shù)母纳平饘僖约昂辖鸩牧系募庸すに囆阅?。也就是說(shuō)，其可以把較大的晶粒進(jìn)行破碎，同時(shí)可以減少裂紋的出現(xiàn)，這樣一來(lái)，也就相當(dāng)于減少了鑄造過(guò)程中的缺陷問(wèn)題，450rolling mill，提高合金的加工性能。

The second advantage of hot rolling is that it can appropriately improve the processing performance of metal and alloy materials. That is to say， it can break the larger grain and reduce the appearance of the crack， which is equivalent to reducing the defects in the casting process and improving the processing performance of the alloy.

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)間最長(zhǎng)只用20min。傳動(dòng)側(cè)的牌坊，七臺(tái)河rolling mill，通過(guò)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，520rolling mill， 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.
