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.

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.

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，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.

皮带输送机的常规设计方法所存在的问题带式输送机常规设计方法实际上是一种安全或是偏于保守的设计方法。例如。选用的输送带安全系数、运行阻力系数偏大，从而造成选用的电动机功率过大，带宽过宽或是抗拉强度要求较高。

The conventional design method of belt conveyor is a safe or cervative design method. For example. The safety factor and the running resistance coefficient of the selected conveyor belt are too large, resulting in excessive power selection, wide bandwidth or high tensile strength.
