軋鋼方法按軋制溫度的不同可分為冷軋與熱軋；按軋制是軋件與軋輥的相對運動關系不同可分為縱軋，橫軋和斜軋；按軋制產品的成型特點還可分為一般軋制，和特殊軋制。此外，由于軋制產品種類繁多，規(guī)格不一。

Rolling method can be divided into cold rolling and hot rolling according to the rolling temperature. According to rolling, the relative motion relatihip between rolling piece and roller can be divided into longitudinal rolling, cross rolling and cross rolling. According to the forming characteristics of rolling products, it can also be divided into general rolling and special rolling. In addition, there are many kinds of rolling products and different specificati.

軋鋼生產對原料有一定的技術要求比如鋼種，斷面形狀和尺寸，重量表面質量等。這些技術要求的考慮是保證鋼材質量所必須的。也是確定和選擇坯料時應具體要考慮的內容。

Steel rolling production has some technical requirements for raw materials such as steel, section shape and size, weight surface quality and so on. These technical requirements are cidered to be necessary to ensure the quality of the steel. It is also the content that should be cidered when determining and selecting the blank.

軋鋼機在輥系的裝配上，主要的應該是軸承的使用，雖然短圓柱的軸承在壽命上都比較長，而且承載的能力也比較大，但是，其不可以承受軸向力，因為使用的是雙列較的接觸軸承.

The main part of the rolling mill assembly of the roll system should be the use of the bearing. Although the bearing of the short cylinder is long in life, and the capacity of the bearing is relatively large, it can not bear the axial force, because the use is a double row of contact bearing.

因為四列的短圓柱軸承在外圈上是可以脫落的，所以，也可以將內圈之間安裝于軋輥在輥頸上，并將外圈安裝在軸承座的內部。 我們從軋鋼機整個裝配的過程來看，軋鋼機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.
