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

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).

閉口式機架為一整體鑄件制成。在經過改進之后，目前的軋機設備采用的是被動一軋一拖式生產方式，可以實現兩道軋制成型，不僅解決了速度配合問題，而且改變了傳統的四道軋制方式，生產效率明顯提高。這種機架形式在型鋼車間中小型軋機上應用較多。其優點是強度和剛度較高，輥跳值較小，產品精度較高。其主要缺點是制造比較困難，裝卸、換輥不方便。軋制壓力較大、對軋件尺寸要求比較嚴格時常采用閉口式機架。如初軋機、型鋼連軋機和型鋼成品軋機等。

The closed frame is made of a whole castings. This type of frame is used more in the small and medium mill in the steel workshop. Its advantages are that the strength and stiffness are high, the roll jump value is small and the precision of the product is high. Its main disadvantage is that it is difficult to manufacture, and it is inconvenient to load and load and change the roll. When the rolling pressure is larger and the requirements for the size of the rolled piece are strict, the closed frame is often used. Such as the early rolling mill, the type steel continuous rolling mill and the steel finished rolling mill, etc.

使用熱軋的第二個優點就在于其可以適當的改善金屬以及合金材料的加工工藝性能。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，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.
