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 conditi are greatly improved, production efficiency is improved, and conditi for realizing automatic operation are provided.

工作辊道靠近工作机座，在工作机座前后将轧件喂入轧机，轧制后接住轧件，又返回送入轧机进行轧制，直到轧成成品后送到下一工序。工作辊道又分为机架辊道、主要工作辊道和辅助工作辊道。机架辊道是指装在工作机座的机架中的少数几个工作辊。

The work roll is close to the working stand, and the workpiece is fed into the rolling mill before and after the machine seat. After rolling, the workpiece is received and rolled back to the mill for rolling, until the finished product is sent to the next process.

The work roller table is also divided into the roller table, the main working roller and the auxiliary working roller.

The rack roller is a few work rolls in the frame of the working frame.

链板输送机以标准链板为承载面，由马达减速机为动力传动；我们可以通过多列链板并行，使链板输送机做的很宽并形成差速，利用多列链板的速度差使多列输送在无挤压的情况下变为单列输送。

The chain plate conveyer takes the standard chain plate as the bearing surface, and the motor reducer is driven by the motor. We can make the chain conveyor be very wide and form the differential speed through the multi chain chain plate.
