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.

軋制技術的有關問題:

般在板邊緣較薄，扎或縱厚度偏差就叫做板凸度。如果板凸度足夠大，板厚偏差可以達到一定值，以至于鋼板不適用于在嚴格要求板厚精度的場合。當厚度偏差增大（在板寬方向上厚度不同）導致在材料設計后產(chǎn)品損失中應考慮增加板厚邊緣。

It is thinner on the edge of the plate, and the deviation of the ligation or longitudinal thickness is called the plate convexity. If the plate convexity is large enough, the thickness deviation of the plate can be reached to a certain value so that the steel plate is not suitable for the situation where the thickness of the plate is strictly required. When the thickness deviation increases (the thickness is different in the width of the plate), the thickness edge of the plate should be added to the loss of the product after the material is designed.

閉口式機架為一整體鑄件制成。這種機架形式在型鋼車間中小型軋機上應用較多。其優(yōu)點是強度和剛度較高，輥跳值較小，產(chǎn)品精度較高。軋機的輥系在換輥前可以預安裝并調(diào)整好，軋機停車后只需較短時間即可換上新輥系。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.

按軋制品種、軋機型式和公稱尺寸來命名?！肮Q尺寸”的原則對型材軋機而言，是以齒輪座人字齒輪節(jié)圓直徑命名。

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.
