辊道是轧钢车间运送轧件的主要设备，其重量占整个轧钢车间设备总重量的40%左右，是轧钢车间中使用多的设备。轧件进出加热炉，在轧机上往复轧制及轧后输送到精整工序等工作均由辊道来完成。

Roller table is the main e for rolling parts in rolling workshop. Its weight accounts for about 40% of the total weight of the whole rolling workshop. It is the most used e in rolling workshop. Rolling in and out of the heating furnace, the rolling mill on the rolling mill and after rolling to the finishing process and other work are completed by the roller.

双层滚筒输送机同样也具备了滚筒的优点。具有输送量大，维护方便等原因。应用于各行业的成品包装箱、周转箱等输送。要求被输送物的底部是平整的。而且每三只滚筒要与底部接触。

Double drum conveyor also has the advantages of drum. It has a large amount of transportation, convenient maintenance and so on. It is applied to the transportation of finished packing boxes and turnover boxes in various industries. The bottom of the conveyer is required to be flat. And every three rollers should be in contact with the bottom.

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.
