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(lái)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(wèn)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.

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(guò)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).

開口式機(jī)架由機(jī)架底座和上橫梁組成。

開口式機(jī)架是型鋼車間常見的一種機(jī)架形式。這種機(jī)架的優(yōu)點(diǎn)是制造簡(jiǎn)單，裝卸、換輥方便。其缺點(diǎn)是強(qiáng)度和剛度較低，軋輥輥跳值較大，影響產(chǎn)品精度，故只適用于大型軋機(jī)。

The open frame is of the frame base and the upper cross beam.  

The open frame is one of the most common forms in the steel workshop. The advantages of this frame are simple manufacturing, loading and unloading, and convenient for roll change. Its disadvantage is that its strength and stiffness are low, the roll roll value is larger and the precision of the product is affected, so it is only suitable for large rolling mill.

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(shuō)，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(lái)，也就相當(dāng)于減少了鑄造過(guò)程中的缺陷問(wèn)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.
