辊道是轧钢车间运送轧件的主要设备，其重量占整个轧钢车间设备总重量的40%左右，是轧钢车间中使用多的设备。轧件进出加热炉，在轧机上往复轧制及轧后输送到精整工序等工作均由辊道来完成。

Roller table is the main equipment for rolling parts in rolling workshop. Its weight accounts for about 40% of the total weight of the whole rolling workshop. It is the most used equipment in rolling workshop. Rolling in and out of the heating furnace, the rolling mill on the rolling mill and after rolling to the finishing process and other work are completed by the roller.

支架多用型钢制成，有焊接和螺栓连接两种结构。为了通用和便于制造，已把上述三种常用辊子的支架作成具有标准长度的通用构件，在设计时可直接选用。

The  is made of  steel with two structures: welding and bolt connection. For the  of generaland convenient manufacturing, the above three common roller  have been used as a common component with a standard length, which can be used directly in the design.

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。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。同时双层滚筒输送机采用一台电机进行驱动，和独立的两台滚筒线相比，节约了一台电机和电控装置的开支，这样为企业节约了成本，但是要注意在设计时要注意两层滚筒线之间的高度要高于物料的高度。

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 requirements are not as strict collective transmission.

皮带输送机的结构参数的优化方法皮带输送机的结构虽然受到了种种工况的限制，而输送机的工作状态是处于满载正常运行的状态，在常规设计计算方法完成后，可以进行采用离散变量优化的网络法，对带式输送机参数进行优化设计 。

Optimization of the structural parameters of belt conveyer, the structure of belt conveyer is restricted by various working conditi, and the working state of the conveyor is in a state of full load. After the completion of the conventional design calculation method, the network method of discrete variable optimization can be used to optimize the parameters of the belt conveyor. Chemical design.
