中間輥道位于拉矯機(jī)和切割設(shè)備之間，用于支承和輸送鑄坯和輸送引錠桿。拉坯時(shí)，中間輥道與拉速同步，送引錠桿時(shí)可以用較高的速度。切割區(qū)輥道為切割區(qū)四周的輥道，該輥道中有幾個(gè)輥?zhàn)有枰祷驍[動(dòng)，以防止切割時(shí)切壞輥?zhàn)雍颓懈钤辰Y(jié)輥面。

The middle roller is located between the pull straightening machine and the cutting equipment, which is used to support and transport billets and to transport ingot bars. The middle roller, and casting speed synchronization, you can use a higher speed to send dummy bar.

The roller section of the cutting area is the roller table around the cutting area, and there are several rollers that need to rise or swing in the roller way, so as to prevent the roller and the cutting slag from sticking to the roller surface when cutting.

The roller is usually made of seamless steel tube, also made of cast iron pipe or other material, and the roller shaft is fixed in the bracket. The rollers and shaft valves are equipped with rolling axis zero. There are three kinds of rolls used in the foundry workshop: light (73), medium (105) and heavy (155). The first two are more used.

對(duì)于大型軋機(jī)來(lái)說(shuō)，尤其是熱軋機(jī)必須用動(dòng)力傳動(dòng)輥道。多的還是集體傳動(dòng)式，特別是長(zhǎng)度不大而軋件斷面很大時(shí)，適宜用集體傳動(dòng)。單獨(dú)傳動(dòng)輥道通常用于長(zhǎng)距離的軋件的傳送。

For large rolling mills, in particular, the hot rolling mill must be powered by a power drive roller. The most important is the collective transmission type, especially when the length is small and the section of the workpiece is very large, it is suitable for the use of collective transmission. The single drive roller is usually used for the transmission of long distance parts.

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)。toavoidfoldingthestriponathinstripofstriptoavoidthehighfinishingspeedofthestripontheroller。單獨(dú)傳動(dòng)優(yōu)點(diǎn)很多，它的制作簡(jiǎn)單，由于不需要傳動(dòng)齒輪及傳動(dòng)軸，從而大大簡(jiǎn)化了輥道的機(jī)械結(jié)構(gòu)，使裝拆、檢修和潤(rùn)滑等問(wèn)題也都大大簡(jiǎn)化了，而且對(duì)輥?zhàn)酉嗷ノ恢弥疁?zhǔn)確度的要求也沒(méi)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.
