              整個軋鋼生產過程總是有以下幾個基本工序組成的:

              坯料準備,包括表面缺陷的清理,表面氧化鐵皮的去除和坯料的預先熱處理等。坯料的加熱,是熱軋生產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.



              精整,是軋鋼生產過程中后一個工序,也是較為復雜的一個工序。他對產品的質量起著終的保證作用。產品的技術要求不同,精整工序的內容也不大相同。精整的工序通常又包括鋼材的卷取,軋后冷卻,矯直,成品熱處理,成品表面清理以及各種涂色等許多具體工序。


              Finishing is the last process in the steel rolling process, and it is also a more complicated process. He has a final guarantee of the quality of the product. The technical requirements of the product are different, and the content of the finishing process is not the same. The finishing process usually includes steel coiling, cooling, straightening products, heat treatment, surface cleaning products and various color and many other specific processes.


              組織軋鋼生產工藝過程首先是為了合格的,即合乎質量要求或技術要求的產品,并且要在保證產品質量基礎上努力提高產量。這一任務的完成不僅取決于生產過程的合理性,而且取決于時間和設備的充分利用程度。


              The process of rolling steel production is first made for qualified products, which are suitable for quality requirements or technical requirements, and we must strive to increase output on the basis of ensuring product quality. The completion of this task depends not only on the rationality of the production process, but also on the full utilization of the time and the equipment.
