Received Date: 20o9 a o3-30 Maanshan Iron and Steel New steel for automobile outer panel is a successful automotive vehicle outer panel board production of key products, production is difficult, very high surface quality requirements. Maanshan Iron and Steel Company steel rolling production line of four new area of product development at the beginning rehabilitation, to locate high-end products, in 2007, before the commissioning of the trial production stage, to give priority to the development of deep-leveling steel plate as a test car research goals. Automotive sheet steel in deep leveling trial process, from hot metal pretreatment, BOF, refining, continuous casting, hot rolling, continuous annealing lines sour rolling to the whole process, all processes of production equipment, technology, production organization, operation time and time again the level of technical research, so as to effectively ensure the deep-drawing performance car plate special steel, plate type and surface quality. The end of 2008, Maanshan Steel leveling New production of deep-sheet auto sheet steel used in the commercial vehicle company JAC light truck body stamping plant test to obtain one outside the board, which in turn fill the Maanshan steel production motor vehicles, the history of the blank sheet. Maanshan Iron and Steel coil supply volumes of the original, has not been screened directly off the metal stamping, forming by drawing, punching, flanging, plastic trimming and other four processes, stamping, automotive outer panel by the site inspection, regardless of surface quality or quality of drawing deformation can meet the quality requirements of light trucks outside the board, one successful product off the assembly line. Maanshan Steel leveling motor vehicles deep steel plate production success, not only marks the Maanshan Iron and Steel explores a new area to adapt to rapid development of high-end products of success, but also the leap into the automobile body in one fell swoop Maanshan Iron and Steel products development company ranks . Wei-line feed ferritic stainless steel production in China has developed rapidly accounted for nearly 30% of the total stainless steel production in China in the past, the main thing is the development of austenitic stainless steel, austenitic stainless steel corrosion resistance and good processability, the user preferences application. The cable body of stainless steel production is very low, poor performance, the application less. Stainless steel production in China in recent years than conventional development, to be greatly increased nickel content, nickel prices soaring international market, resulting in the rapid production increase in the cost of austenitic stainless steel, straight-line rise in sales prices, thereby facilitating the production and consumption in terms of ferritic stainless steel expectations and development. Major domestic steel producers have strengthened ferritic stainless steel research and development work, so that the production of ferritic stainless steel increasing variety, quality has been steadily increasing proportion of its production increase by leaps and bounds this. 2008, ferritic stainless steel production in China has reached about 200 million t, accounting for 29.4% of total stainless steel, an increase of 3 percentage points, so that the structure of varieties of stainless steel for the first time close to the international level of developed countries. In 2008, China developed the T4003, 441,443,444,446, B430LNT, TCS345, B4003M, 470L1 and a series of new ferritic stainless steel products, widely used in transportation, power, construction, household appliances, kitchen and other areas .
