輥道是利用圓筒式的輥子之轉(zhuǎn)動來輸送軋件的運輸設(shè)備。它把軋制生產(chǎn)過程的各個工序互相聯(lián)結(jié)起來。實現(xiàn)操作機械化，大大改善勞動條件，提高生產(chǎn)效率，為實現(xiàn)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.

特別是輸出輥道，過去多采用上述方法對中，但是近有把輥距縮小的傾向，因而采用后一種斜輥布置方式的輥道正在減少。這是為了在軋制薄規(guī)格的帶鋼時避免使帶鋼在輥道上因終軋速度高而造成折疊。此外，對于輥道的速度和輥子直徑也要充分考慮好。

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.

用這種支架時，輥子安裝完畢需用鋼絲進行鎖緊（即相鄰3～5個輥子軸用鋼絲串在一起）。輥子Φ155的支架采用槽鋼，輥子軸用壓板和螺栓固定在槽鋼翼緣上。

When the bracket is used, the roller is installed with the steel wire to be locked (that is, the 3~5 roller shafts are strung together with steel wire). The support of the roller 155 is used in the channel steel, and the roller shaft is fixed on the flange of the channel steel with the press plate and bolt.

皮帶輸送機的常規(guī)設(shè)計方法所存在的問題帶式輸送機常規(guī)設(shè)計方法實際上是一種安全或是偏于保守的設(shè)計方法。例如。選用的輸送帶安全系數(shù)、運行阻力系數(shù)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.
