              輥道是利用圓筒式的輥子之轉動來輸送軋件的運輸設備。它把軋制生產過程的各個工序互相聯結起來。實現操作機械化,大大改善勞動條件,提高生產效率,為實現自動化操作提供條件。



              The roller is the transport equipment that uses the rotation of the cylindrical roller to transport the rolled piece. It joins each of the processes in the rolling process. Mechanization of operation is realized, labor conditi are greatly improved, production efficiency is improved, and conditi for realizing automatic operation are provided.


              工作輥道靠近工作機座,在工作機座前后將軋件喂入軋機,軋制后接住軋件,又返回送入軋機進行軋制,直到軋成成品后送到下一工序。工作輥道又分為機架輥道、主要工作輥道和輔助工作輥道。機架輥道是指裝在工作機座的機架中的少數幾個工作輥。

              The work roll is close to the working stand, and the workpiece is fed into the rolling mill before and after the machine seat. After rolling, the workpiece is received and rolled back to the mill for rolling, until the finished product is sent to the next process.

              The work roller table is also divided into the roller table, the main working roller and the auxiliary working roller.

              The rack roller is a few work rolls in the frame of the working frame.




              皮帶輸送機的常規設計方法所存在的問題帶式輸送機常規設計方法實際上是一種安全或是偏于保守的設計方法。例如。選用的輸送帶安全系數、運行阻力系數偏大,從而造成選用的電動機功率過大,帶寬過寬或是抗拉強度要求較高。



              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.


              皮帶輸送機的結構參數的優化方法皮帶輸送機的結構雖然受到了種種工況的限制,而輸送機的工作狀態是處于滿載正常運行的狀態,在常規設計計算方法完成后,可以進行采用離散變量優化的網絡法,對帶式輸送機參數進行優化設計 。



              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.
