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.

中间辊道位于拉矫机和切割设备之间，用于支承和输送铸坯和输送引锭杆。拉坯时，中间辊道与拉速同步，送引锭杆时可以用较高的速度。切割区辊道为切割区四周的辊道，该辊道中有几个辊子需要升降或摆动，以防止切割时切坏辊子和切割渣粘结辊面。

The middle roller is located between the pull straightening machine and the cutting equipment, which is used to support and transport billets and to transport ingot bars. The middle roller, and casting speed synchronization, you can use a higher speed to send dummy bar.

The roller section of the cutting area is the roller table around the cutting area, and there are several rollers that need to rise or swing in the roller way, so as to prevent the roller and the cutting slag from sticking to the roller surface when cutting.

支柱一般采用型钢焊接而成，上部用螺栓与支架连接，下部用地脚螺栓与地坪固定。按用途支柱可分为对接支柱和中间支柱，两标准段支架之间采用对接支柱支承，其余（包括端部）则采用中间支柱支承。支柱的设计一般按受压柱的稳定性来控制。

The pillar is usually welded by the steel type steel, the upper part is connected with the bolt and the support, and the bottom is fixed with the ground bolt and the floor.to the use pillar, it can be divided into the docking pillar and the middle pillar. The two bracket is supported by the docking pillar, while the rest (including the ends) is supported by the intermediate support. The design of the pillar is generally by the stability of the compression column.
