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，辊道哪家好，这一组辊道叫辅助工作辊道，辊道生产商，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，辊道，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，圣霖国际辊道，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 ?he been used as a common component with a standard length， which can be used directly in the design.

空转辊道——通常借助轧件重力来推动，所以辊道之平面多做成与水平面之间有斜度，以利用重力作用，因此又称为重力辊道。一般小型轧机的辊道，特别是升降台上的辊道，尽可采用重力辊道而不必采用转动辊道。有些工作辊道的延长部分也有采用重力辊道的。

The idle roller table is usually driven by the grity of the rolled piece， so the plane of the roller table is made of a gradient between the horizontal plane and the horizontal plane， so as to make use of the grity effect， so it is also called the grity roller table. The rolling mill of a small mill， especially the roller table on the lift table， can use the grity roller without using the rotating roller table. Some of the lengthening parts of the working rollers also use the gritational roller.
