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.
不锈钢生产的快速增长势必对原材料市场产生影响，带来镍价以及废钢、矿石、煤炭价格的不断上涨，使不锈钢生产者日益感到了成本升高的压力，不锈钢生产的利润越来越小。这就迫使全世界不锈钢的生产厂家 大力整合生产力的基础上，不断开发新工艺 、新技术、发展高生产能力的装备，以期达到在改进产品质量的同时，提高生产效率，降低生产成本，提高产品市场竞争力的目的。
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.
