The production technology of stainless steel refining outside the furnace (especially AOD), continuous casting and wide cold rolling mill, obtained the substantial progress of new science and technology of stainless steel production line of thin slab continuous casting and rolling mill, strip casting, metal smelting and rolling of stainless steel continuous annealing and pickling production.
The development of production technology in order to cope with the market competition of the new requirements of stainless steel products increased, these new requirements not only in performance and surface characteristics of steel grades, specifications, requirements, and continuously improve production efficiency, reduce production costs.
不銹鋼生產的快速增長勢必對原材料市場產生影響，帶來鎳價以及廢鋼、礦石、煤炭價格的不斷上漲，使不銹鋼生產者日益感到了成本升高的壓力，不銹鋼生產的利潤越來越小。這就迫使全世界不銹鋼的生產廠家 大力整合生產力的基礎上，不斷開發新工藝 、新技術、發展高生產能力的裝備，以期達到在改進產品質量的同時，提高生產效率，降低生產成本，提高產品市場競爭力的目的。
Rapid growth of steel production is bound to have an impact on the market of raw materials, bring the price of nickel and rising scrap steel, ore, coal prices, the stainless steel producers increasingly feel the increasing cost pressure, the production of stainless steel increasingly small profits. This forced the stainless steel all over the world manufacturers strong integration of productive forces, the development of new technology, new technology, development of high capacity equipment, in order to improve product quality, improve production efficiency, reduce production cost, improve the market competitiveness of the purpose.
The production of cold rolled stainless steel strip plays an important role in the production of stainless steel. About 70% of the stainless steel has been transformed into cold rolled strip, which is the main form of market consumption. According to the traditional process, from hot rolled stainless steel strip to cold-rolled stainless steel products production cost roughly 360 euros /t, which costs accounted for the main part of the cold rolling process, especially the 20 roller reversible rolling mill John Lone entertainment city estate, cold-rolled cost to half, roughly 180 euros /t. Therefore, it is very important to develop and adopt new technology and new technology of stainless steel cold rolling production to improve production efficiency, reduce production costs and improve the comprehensive competitiveness of products in the market.
