軋制變形制度：即一定軋制條件下從坯料到成品的總變形量和軋制的總道次，各機(jī)組的總變形量各道次的變形量，軋制方式等。橫軋有兩種類型：一類是軋輥孔型沿軸向是不變的，沿徑向呈周期變化。對(duì)于型鋼，軋件在孔型中軋制，并且在每個(gè)孔型中軋制一道，因此，型鋼的變形制度是以孔型的形式表示的，孔型的設(shè)計(jì)確定后變形制度就確定了。

Rolling system: that under certain rolling condition the total deformation from the blank to the finished product and the total rolling pass, deformation of the total deformation of each unit of each pass, rolling etc.. For the section steel, the rolled piece is rolled in the pass and rolled in one pass. Therefore, the deformation system of the section steel is expressed in the form of pass, and the deformation system is determined after the pass design is determined.

從金屬學(xué)角度來看，熱軋與冷軋的界限應(yīng)該以金屬再結(jié)晶的溫度來區(qū)分，即低于再結(jié)晶溫度的軋制為冷軋；高于再結(jié)晶溫度的軋制為熱軋。而鋼的再結(jié)晶溫度一般在450℃～600℃范圍之內(nèi)。

From the point of view of metallization, the boundary between hot rolling and cold rolling should be distinguished from the temperature of recrystallization of metal, that is, the rolling that is lower than the recrystallization temperature is cold rolling, and the rolling that is higher than the recrystallization temperature is hot rolling. The recrystallization temperature of steel is generally within the range of 450 ~ 600.

因?yàn)樗牧械亩虉A柱軸承在外圈上是可以脫落的，所以，也可以將內(nèi)圈之間安裝于軋輥在輥頸上，并將外圈安裝在軸承座的內(nèi)部。 我們從軋鋼機(jī)整個(gè)裝配的過程來看，軋鋼機(jī)中軸承以及軸承座在受力的情況上都是比較良好的.

Because the four columns of short cylindrical bearings can be shedding in the outer ring, the inner ring can also be installed between the roller and the roll neck, and the outer ring is installed inside the bearing seat. In terms of the whole assembly process of rolling mills, the bearings and bearing housings in rolling mills are relatively good in force.

我國經(jīng)濟(jì)一直快速穩(wěn)定發(fā)展，而軋鋼設(shè)備行業(yè)也是迅速發(fā)展，在我國軋鋼機(jī)設(shè)備行業(yè)中，自動(dòng)化和計(jì)算機(jī)控制系統(tǒng)主要還是靠引進(jìn)。

China's economy has been developing rapidly and steadily, and the steel rolling equipment industry is developing rapidly. In China's steel rolling machine equipment industry, automation and computer systems are mainly
