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.

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.

軋機(jī)在軋制過程中由軋制力所引起的內(nèi)力沿機(jī)座各承載零件分布的應(yīng)力曲線，稱作應(yīng)力線。為了提高軋機(jī)剛度，減少機(jī)架及各承載零件的變形，采取各種技術(shù)措施后，將這種應(yīng)力線縮短了的軋機(jī)，稱為短應(yīng)力線軋機(jī)。它是高剛度軋機(jī)中的一種。

The stress curve of the rolling force, which is caused by the internal force of the rolling force, along the bearing parts of the frame, is called the stress line. In order to improve the rigidity of rolling mill and reduce the deformation of rack and bearing parts, after taking various technical measures, the mill which shortens the stress line is called short stress line mill. It is one of the high rigidity rolling mills.

軋機(jī)專業(yè)廠家介紹，其實(shí)從實(shí)際生產(chǎn)作業(yè)來看，關(guān)于冷軋機(jī)的安全生產(chǎn)主要包括三個(gè)方面，分別為：定期檢修、日常安全操作以及日常的培訓(xùn)管理等。

In fact, from the actual production operation, the safety production of the cold rolling mill mainly includes three aspects, which are the regular maintenance, the daily safety operation and the daily training etc.
