關于機械產(chǎn)量，二十世紀七十年代后期，控制冷卻技術的發(fā)展使得鋼板軋制中的TMCP技術得到廣泛發(fā)展。

With regard to mechanical production, the development of cooling technology in the late 1970s made the TMCP technology develop widely in steel plate rolling.

開坯機為兩輥水平軋機，坯料送至軋機前后，根據(jù)軋制程序表進入相應的軋槽可逆軋制，并通過翻鋼裝置將軋件夾緊進行翻轉。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).

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堋Ｒ簿褪钦f，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.
