在带钢热连轧机上使用着许多辊道，它们被分成若干段，每一段辊道或者以***的或者以与轧辊同步的速度和方向运送轧件。

为使轧件能够在辊道中心运行，采用鼓形辊，并且交替地使左右两边的水平面稍微倾斜，或者使辊子的轴线与轧件运行方向的交角交替地比直角稍微偏斜一些。

Many roller tables are used on hot strip mills. They are divided into several segments, each section of rollers or parts transported independently or at the same speed and direction with the rollers.

In order to make the workpiece can be run in the center of the drum shaped roller, roller, and alternately on both sides of the horizontal plane or slightly tilted, the roller axis and the running direction of the rolling angle alternately than some slightly skewed angle.

为使铸坯平稳迅速地运送，有时将这个区的辊道设计成可升降的。辊道按驱动方式可分为集中传动辊道和单独传动辊道两种。集中传动辊道由一台电机带动一组辊子，通过电机一减速机一链轮传动，或者通过电机一减速机～长轴一伞齿轮传动方式传动。

In order to deliver the billet ***oothly and quickly, the roller table in this area is sometimes designed to be lifted and lifted. The roller table can be divided into two types: the drive roller and the separate drive roller. The driven roller table is driven by a motor to a set of rollers, driven by a motor, a reducer or a sprocket, or through a motor, a reducer, a long shaft and a bevel gear tran***ission mode.

辊子一般采用无缝钢管制成，也有用铸铁管或其他材料制造的，辊子轴固定在支架中。辊子与轴之阀装有滚动轴零。铸造车间常用的辊子有三种：轻型（Φ73）、中型（Φ105）和重型（Φ155）。其中前两种用的较多。

The roller is usually made of seamless steel tube, also made of cast iron pipe or other material, and the roller shaft is fixed in the bracket. The rollers and shaft valves are equipped with rolling axis zero. There are three kinds of rolls used in the foundry workshop: light (73), medium (105) and he***y (155). The first two are more used.
