The development of production technology of Cold-rolled stainless steel strip
Contact nowOver the past 10 years, technology in the production of stainless steel, refining furnace (especially AOD), continuous casting and more wide-high cold rolling mill on the basis of thin slab continuous casting and rolling mill, continuous casting steel, iron smelting and rolling of stainless steel annealing pickling line for the production of stainless steel, such as the forefront of the new technology achieved substantive progress.
Production and technological development in response to market competition to improve the stainless steel products the new requirements, these new requirements not only in steel, specifications, performance and surface characteristics, but also continuously improve production efficiency and reduce production costs. The rapid growth of stainless steel production is bound to have an impact on the raw materials market, bringing nickel and scrap prices, ores, coal prices rising, stainless steel producers to increasingly feel the pressure of increased costs, stainless steel production profits is getting smaller and smaller. This forced the stainless steel producers around the world to integrate on the basis of productivity, and constantly develop new techniques and new technology, the development of high-capacity equipment to achieve in improving the quality of products, improve production efficiency and reduce production costs, improve product The purpose of market competitiveness.
Cold-rolled stainless steel strip in the production of stainless steel production in a very important position. Around 70% of the conversion into cold-rolled stainless steel strip, as the main consumer market product form. According to the current line of traditional crafts, from the hot-rolled stainless steel strip to cold-rolled stainless steel products production costs roughly 360 euros / t, the cost of cold-rolled processes accounts for the main part, especially in a 20 roller reversible production of the mill, cold Rolling to half of the cost, roughly 180 euros / t. Therefore, vigorously developing, using cold-rolled stainless steel production of new techniques and new technology to improve production efficiency and reduce production costs, improve product in the market's comprehensive competitiveness is crucial.
Based on the traditional technology route, contrast, focuses on rolling annealing and pickling line (cold-rolled stainless steel will be the five independent processes - coil preparation, hot strip annealing and pickling line, cold-rolled, cold-rolled strip annealing and pickling line of peace and integration into a continuous production line) and the independent line of cold-rolled (ie set up a separate multi-stand cold rolling mill, hot rolled strip in front of configuration annealing and pickling line, after rolling configuration with a comprehensive fine the entire device, such as formation, tensile straightening, trimming and inspection of cold-rolled strip annealing and pickling line) advantage. What should be used depends on what line of stainless steel manufacturers in all of the specific conditions. However, in the high-capacity and high surface quality, large-scale, continuous in the direction of development, is stainless steel production plant and equipment factory in the direction of development efforts.
