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 equipment 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 equipment 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.
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.
出坯辊道是切割区辊道之后至冷床之前的辊道，由若干辊子组成，快速将切割后的定火铸坯输送至横移区辊道。
紧接着出坯辊道的是横移区辊道，该区辊道接受出坯辊道来的铸坯，将铸坯输送至固定挡板之前，由横移机构将每流铸坯输送到冷床或其他区域。
The billet is before and after cutting roller roller roller and cooling bed, of a plurality of rollers, the rapid fire set after cutting billet conveying roller to tr***erse.
Then a blank roller is tr***ersing roller, the roller roller to accept a billet, billet before delivery to the fixed baffle, by tr***ersing mechani*** each flow casting billet transporting to the bed or other areas.
同时双层滚筒输送机采用一台电机进行驱动，和***的两台滚筒线相比，节约了一台电机和电控装置的开支，这样为企业节约了成本，但是要注意在设计时要注意两层滚筒线之间的高度要高于物料的高度。
At the same time, a double layer roller conveyor is driven by a motor. Compared with the two independent lines, it s***es the expenses of an electric motor and electronic device. This s***es the cost for the enterprise, but attention should be paid to the height of the two layers of the roller line when the design is higher than the material.
