特别是输出辊道，过去多采用上述方法对中，但是近有把辊距缩小的倾向，因而采用后一种斜辊布置方式的辊道正在减少。这是为了在轧制薄规格的带钢时避免使带钢在辊道上因终轧速度高而造成折叠。此外，对于辊道的速度和辊子直径也要充分考虑好。

In particular, the output roller table used to use the above methods in the past, but recently there is a tendency to narrow the distance between rolls. Therefore, the roller table with the latter one is decreasing. to avoid folding the strip on a thin strip of strip to avoid the high finishing speed of the strip on the roller. In addition, the speed of the roller and the diameter of the roller should be fully cidered. 单独传动辊道为一个电机带动一个辊子。这种辊道结构简单，操纵灵活，维修方便。皮带输送机从经济上节省占地等方面进行考虑一般不设置输送线并行的输送方式在特别重要的环节当中也有采用并行两条输送，其中一条备用，用都是采用多条输送机进行串联。根据铸坯的断面尺寸计算选择辊子直径和辊身长度，切割区后的辊道辊间距取决于定尺长度。切割前辊道速度与拉坯速度一致，切割后要迅速输送铸坯，辊道速度一般为20～30m/min。

A single drive roller is used as a motor to drive a roller. The roller table is simple in structure, flexible in operation and convenient in maintenance. According to the section size of the slab, the diameter of the roller and the length of the roller are calculated. The roller spacing after the cutting area depends on the length of the length. Before cutting roller speed and casting speed, after cutting to transfer slab, roller speed is 20 ~ 30m/min. 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 gravity 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 gravity effect, so it is also called the gravity roller table. The rolling mill of a small mill, especially the roller table on the lift table, can use the gravity roller without using the rotating roller table. Some of the lengthening parts of the working rollers also use the gravitational roller. 新式的高速热轧机及连续式热轧机一般都采用单独传动系统。Itsweightaccountsforabout40%ofthetotalweightofthewholerollingworkshop。单独传动优点很多，它的制作简单，由于不需要传动齿轮及传动轴，从而大大简化了辊道的机械结构，使装拆、检修和润滑等问题也都大大简化了，而且对辊子相互位置之准确度的要求也没有集体传动时那样严格。

The new type of high speed hot rolling mill and continuous hot rolling mill generally use a separate transmission system. Individual drive has many advantages, making it simple, because it does not need the transmission gear and the transmission shaft, which greatly simplifies the mechanical structure of the roller, the assembly and disassembly, maintenance and lubrication problems are greatly simplified, and the accuracy of the location of each roller re are not as strict collective transmission.
