              鋼錠或鋼坯在常溫下很難變形,不易加工,需要進行加熱到1100℃到1250℃進行軋制,這種軋制工藝叫做熱軋。在常溫下的軋制一般理解為冷軋.


              Ingot or billet are difficult to be deformed at normal temperature and are not easy to be processed. They need to be heated to 1100 and 1250 C for rolling. This rolling process is called hot rolling. Rolling at normal temperature is generally understood as cold rolling.


              采用控制軋制工藝時,為了防止原始奧氏體晶粒過分長大,一般采用較低的加熱溫度和開軋溫度。由于開軋溫度高,變形后的奧氏體晶粒會發生再結晶而細化,如在這個階段停止變第八節控制軋制技術形,軋件即隨溫度下降而產生相變。

              In order to prevent the original austenite grain growing too much, the lower heating temperature and rolling temperature are generally adopted in the rolling process. Due to the high rolling temperature, the austenite grain after the deformation will be recrystallized and refined. For example, the eighth section  rolling technology is stopped at this stage, and the phase change is produced as the temperature drops.


              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.


              軋鋼機的技術現在越來越精細了,不同的類型,不同的物料都有不同的相對應的軋鋼機設備,這也就讓我們的物料更細致化了,且它們每一個地方的。



              The technology of rolling mill is now more and more fine, different types, different materials have different corresponding rolling mill equipment, which makes our materials more detailed, and they are perfect every place.
