開坯機(jī)為兩輥水平軋機(jī)，坯料送至軋機(jī)前后，根據(jù)軋制程序表進(jìn)入相應(yīng)的軋槽可逆軋制，并通過翻鋼裝置將軋件夾緊進(jìn)行翻轉(zhuǎn)。一般軋制5-7道次(多9道次)。

The blooming machine is a two roll horizontal mill, and the billet is sent to the front and rear mills. According to the rolling schedule, the roll is rolled into the corresponding rolling groove, and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).

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)專業(yè)廠家說，熱軋機(jī)的優(yōu)點(diǎn)主要可以歸納為三個(gè)方面。一點(diǎn)，采用熱軋可以明顯的減少能耗，降低成本。此外，熱軋時(shí)可以發(fā)揮出較高的金屬塑性，而且所產(chǎn)生的變形抗力較小，能夠有效的防止金屬出現(xiàn)嚴(yán)重的變形問題。

The mill manufacturer explains that the advantages of the hot rolling mill can be summed up in three aspects. First, the use of hot rolling can significantly reduce energy cumption and reduce costs. In addition, hot rolling can give full play to the high metal plasticity, and the deformation resistance is small, which can effectively prevent the serious deformation of the metal.

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，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，也就相當(dāng)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.
