辊道是利用圆筒式的辊子之转动来输送轧件的运输设备。它把轧制生产过程的各个工序互相联结起来。实现操作机械化，大大改善劳动条件，提高生产效率，为实现自动化操作提供条件。
The roller is the transport equipment that uses the rotation of the cylindrical roller to transport the rolled piece. It joins each of the processes in the rolling process. Mechanization of operation is realized, labor conditions are greatly improved, production efficiency is improved, and conditions for realizing automatic operation are provided. 特别是输出辊道，过去多采用上述方法对中，但是近有把辊距缩小的倾向，因而采用后一种斜辊布置方式的辊道正在减少。这是为了在轧制薄规格的带钢时避免使带钢在辊道上因终轧速度高而造成折叠。此外，对于辊道的速度和辊子直径也要充分考虑好。 In particular, the output roller table used to use the above methods in the past, but recently there is a tendency to narrow the distance between rolls. Therefore, the roller table with the latter one is decreasing. to avoid folding the strip on a thin strip of strip to avoid the high finishing speed of the strip on the roller. In addition, the speed of the roller and the diameter of the roller should be fully considered. 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 have been used as a common component with a standard length, which can be used directly in the design. （作者： 来源：）
