在帶鋼熱連軋機(jī)上使用著許多輥道,它們被分成若干段,每一段輥道或者以獨(dú)立的或者以與軋輥同步的速度和方向運(yùn)送軋件。
為使軋件能夠在輥道中心運(yùn)行,采用鼓形輥,并且交替地使左右兩邊的水平面稍微傾斜,或者使輥?zhàn)拥妮S線與軋件運(yùn)行方向的交角交替地比直角稍微偏斜一些。
Many roller tables are used on hot strip mills. They are divided into several segments, each section of rollers or parts transported independently or at the same speed and direction with the rollers.
In order to make the workpiece can be run in the center of the drum shaped roller, roller, and alternately on both sides of the horizontal plane or slightly tilted, the roller axis and the running direction of the rolling angle alternately than some slightly skewed angle.
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(shí)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?zhàn)又睆揭惨浞挚紤]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.
工作輥道靠近工作機(jī)座,在工作機(jī)座前后將軋件喂入軋機(jī),軋制后接住軋件,又返回送入軋機(jī)進(jìn)行軋制,直到軋成成品后送到下一工序。工作輥道又分為機(jī)架輥道、主要工作輥道和輔助工作輥道。機(jī)架輥道是指裝在工作機(jī)座的機(jī)架中的少數(shù)幾個(gè)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.
新式的高速熱軋機(jī)及連續(xù)式熱軋機(jī)一般都采用單獨(dú)傳動(dòng)系統(tǒng)。Rollertableisthemainequipmentforrollingpartsinrollingworkshop。單獨(dú)傳動(dòng)優(yōu)點(diǎn)很多,它的制作簡單,由于不需要傳動(dòng)齒輪及傳動(dòng)軸,從而大大簡化了輥道的機(jī)械結(jié)構(gòu),使裝拆、檢修和潤滑等問題也都大大簡化了,而且對輥?zhàn)酉嗷ノ恢弥疁?zhǔn)確度的要求也沒有集體傳動(dòng)時(shí)那樣嚴(yán)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 requirements are not as strict collective transmission.
