对于中阀辊道，除了要求对中之外，为了进行精轧人口温度控制，辊道哪家好，要求轧件能在中间辊道上往复运动，并且为了提高末架粗轧机和精轧机的速度控制精度，以前常用的集体传动方式正在被单独传动方式代替。
For the valve roller， in addition to the requirements of， in order to finish rolling temperature requirements of population， in the middle of the roller on the reciprocating motion， and in order to improve the frame at the end of roughing mill and finishing mill speed precision， instead of the commonly used collective tran***ission mode being separate tran***ission mode.
为使铸坯平稳迅速地运送，辊道设备，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，圣霖国际辊道， 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.
空转辊道——通常借助轧件重力来推动，所以辊道之平面多做成与水平面之间有斜度，以利用重力作用，因此又称为重力辊道。一般小型轧机的辊道，辊道，特别是升降台上的辊道，尽可采用重力辊道而不必采用转动辊道。有些工作辊道的延长部分也有采用重力辊道的。
The idle roller table is usually driven by the gr***ity of the rolled piece， so the plane of the roller table is made of a gradient between the horizontal plane and the horizontal plane， so as to make use of the gr***ity effect， so it is also called the gr***ity roller table. The rolling mill of a ***all mill， especially the roller table on the lift table， can use the gr***ity roller without using the rotating roller table. Some of the lengthening parts of the working rollers also use the gr***itational roller.
