連續(xù)加熱爐連續(xù)加熱爐包括推鋼式加熱爐、步進式爐、轉底式爐、分室式爐等連續(xù)加熱爐，但習慣上常指推鋼式爐。連續(xù)加熱爐多數(shù)用于軋制前加熱金屬料坯，少數(shù)用于鍛造和熱處理。

It is named according to the varieties of rolling, the type of rolling mill and the nominal size. The principle of "nominal size"

For rolling mills, they are named after the gear ring and the pitch diameter of the herringbone gear.

軋機專業(yè)廠家介紹，其實從實際生產作業(yè)來看，關于冷軋機的安全生產主要包括三個方面，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.

使用熱軋的第二個優(yōu)點就在于其可以適當?shù)母纳平饘僖约昂辖鸩牧系募庸すに囆阅?。也就是說，其可以把較大的晶粒進行破碎，同時可以減少裂紋的出現(xiàn)，這樣一來，也就相當于減少了鑄造過程中的缺陷問題，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.
