開坯機(jī)為兩輥水平軋機(jī)，坯料送至軋機(jī)前后，根據(jù)軋制程序表進(jìn)入相應(yīng)的軋槽可逆軋制，并通過翻鋼裝置將軋件夾緊進(jìn)行翻轉(zhuǎn)。一般軋制5-7道次(多9道次)。

The blooming machine is a two roll horizontal mill, and the billet is sent to the front and rear mills. According to the rolling schedule, the roll is rolled into the corresponding rolling groove, and the workpiece is clamped and turned through the turning device. The general rolling is 5-7 times (up to 9 times).

輥系快速整體更換不需吊車，采甩軋輥牽引小車和橫移臺(tái)車結(jié)合的換輥方式，導(dǎo)衛(wèi)橫梁安裝在軋機(jī)軸承座上，更換軋輥時(shí),導(dǎo)衛(wèi)及橫梁隨輥系整套從牌坊窗口中拖出，一次換輥時(shí)間僅為20min.

You don't need to replace the whole fast roller roller way for mining crane, trolley and swing roller traversing trolley with the guide beam is installed on the bearing seat of rolling mill, roll changing, guide and beam with roll set pulled from the housing window, a roll change time is only 20min.

驅(qū)動(dòng)電機(jī)斜置在鋸機(jī)底座上，通過傘齒輪及主傳動(dòng)軸帶動(dòng)鋸片，鋸片由液壓裝置鎖緊在傳動(dòng)軸上。鋸片進(jìn)鋸由液壓驅(qū)動(dòng)，進(jìn)鋸速度根據(jù)鋸切阻力由比例閥調(diào)節(jié)。當(dāng)軋件斷面較大、鋸切阻力高時(shí)，進(jìn)鋸速度慢，反之，進(jìn)鋸速度塊。

The driving motor is inclined on the base of the saw machine, and the saw blade is driven through the bevel gear and the main drive shaft, and the saw blade is locked on the drive shaft by the hydraulic device. The sawing saw is driven by hydraulic pressure, and the speed of the saw is adjusted by the proportional valve according to the cutting resistance. When the section of the rolled piece is large and the cutting resistance is high, the speed of the saw is slow, and conversely, the speed block of the saw.

據(jù)說在14世紀(jì)歐洲就有軋機(jī)，但有記載的是1480年意大利人達(dá)·芬奇（Leonardo da Vinci）設(shè)計(jì)出軋機(jī)的草圖。1553年法國人布律列爾(Brulier)軋制出金和銀板材,用以制造錢幣。此后在西班牙、比利時(shí)和英國相繼出現(xiàn)軋機(jī)。

It is said that there are rolling mills in Europe in the fourteenth Century, but it is recorded that in 1480, Leonardo Da Vinci (Italian Italian designer Da Finch) designed the draft for rolling mills. In 1553 the French law Adler cloth (Brulier) rolled gold and silver plate, used in the manufacture of coins. Since then, rolling mills have been rolled out in Spain, Belgium and Britain.
