保持工作輥的上輥和下輥相對(duì)于軋機(jī)中心線對(duì)稱且在軸線方向上移動(dòng)。這種的工作輥移動(dòng)的設(shè)計(jì)，是用來改變工作輥和支撐輥的偏移需要大的移動(dòng)量。這種大移動(dòng)量的采用需要大量的改裝費(fèi)用，并且需要解決很多問題.

The upper and lower rolls of the work roll are symmetrical and move in the direction of the axis of the rolling mill. The movement of this work roll is designed to change the shift of work rolls and support rolls to require large amounts of movement. The use of this large shift of momentum requires a lot of modification costs, and many problems need to be solved.

閉口式機(jī)架為一整體鑄件制成。這種機(jī)架形式在型鋼車間中小型軋機(jī)上應(yīng)用較多。其優(yōu)點(diǎn)是強(qiáng)度和剛度較高，輥跳值較小，產(chǎn)品精度較高。其主要缺點(diǎn)是制造比較困難，裝卸、換輥不方便。軋制壓力較大、對(duì)軋件尺寸要求比較嚴(yán)格時(shí)常采用閉口式機(jī)架。Therodisdrivenbythemoldtomakethereverserotationmovementwiththemold。如初軋機(jī)、型鋼連軋機(jī)和型鋼成品軋機(jī)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(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堋Ｒ簿褪钦f，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.
