關(guān)于機(jī)械產(chǎn)量，二十世紀(jì)七十年代后期，控制冷卻技術(shù)的發(fā)展使得鋼板軋制中的TMCP技術(shù)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(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).

使用熱軋的第二個優(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.
