主要工作辊道紧靠工作机架，它将轧件喂入轧机和接受轧出轧件，因此它是经常参加工作的辊道，故称主要工作辊道。
轧件长度超过主要工作辊道时，由另一组工作辊道参加工作，这一组辊道叫辅助工作辊道，或称为延伸辊道。
The main work table is close to the work rack. It will feed the rolling piece into the rolling mill and accept rolling and rolling parts. Therefore, it is a roller table that often works. So it is called the main work roller table.
When the length of the rolled piece exceeds the main work roller Road, another group of working rollers is involved in the work. This group of rolls is called the auxiliary work roller, or the extension roller.
支架多用型钢制成，有焊接和螺栓连接两种结构。为了通用和便于制造，已把上述三种常用辊子的支架作成具有标准长度的通用构件，在设计时可直接选用。
The is made of steel with two structures: welding and bolt connection. For the of generaland convenient manufacturing, the above three common roller h***e been used as a common component with a standard length, which can be used directly in the design.
包胶滚筒的寿命是比较长的，像这种要求就是要寿命长的，因为包在滚筒上边也不是很方便取下来呀，所以这就又验证一点.
The life of the rubber drum is long, and the requirement is long life, because it is not very convenient to take the package on the top of the drum, so this will verify the first point again.
