              整個軋鋼生產(chǎn)過程總是有以下幾個基本工序組成的:

              坯料準(zhǔn)備,包括表面缺陷的清理,表面氧化鐵皮的去除和坯料的預(yù)先熱處理等。坯料的加熱,是熱軋生產(chǎn)工藝過程的重要工序。


              The whole rolling process of steel rolling is always composed of the following basic processes:

              Preparation of the billet, including the cleaning of surface defects, the removal of the iron oxide skin on the surface, and the pre heat treatment of the blank. The heating of the billet is an important process in the process of hot rolling.



              軋制速度控制:即軋制時對各道次軋輥的線速度以及每道中不同階段的軋輥的速 度的具體規(guī)定,也叫速度規(guī)程。

              Rolling speed : that is to say, the speed regulation is also specified for the speed of each roller and the speed of each roller  different stages in rolling.


              鋼錠或鋼坯在常溫下很難變形,不易加工,需要進(jìn)行加熱到1100℃到1250℃進(jìn)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.


              軋鋼機(jī)的技術(shù)現(xiàn)在越來越精細(xì)了,不同的類型,不同的物料都有不同的相對應(yīng)的軋鋼機(jī)設(shè)備,這也就讓我們的物料更細(xì)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.
