3月末,本钢在成功稳定批量生产冷轧O5汽车面板后,以研制、生产出5吨热镀锌汽车面板,在华晨一次试验成功,通过认证,将用于“中华尊驰”轿车左右翼子板制件,共483件。这标志着本钢成为国内仅有几家能生产热镀锌汽车面板的钢铁企业。为了解决汽车车身的锈蚀问题,汽车板经历了从传统的冷轧薄板到涂镀薄板的巨大变化。汽车用涂镀薄板既要具备优良的耐蚀性,还要满足其他不同性能的要求,诸如冲压成形性、焊接性、磷化处理性以及
At the end of March, after successful and steady mass production of cold-rolled O5 automotive panels, Bengang successfully developed and produced 5 tons of hot-dip galvanized automobile panels. After a successful trial at Brilliance, it passed the certification and will be used in the “Zhonghua Zunzi” sedan Fender parts, a total of 483. This marks that Benxi Iron and Steel become the only domestic can produce hot-dip galvanized automotive panel steel companies. In order to solve the problem of automobile body corrosion, automobile panels have undergone tremendous changes from traditional cold-rolled sheets to coated sheets. Automotive coated sheet is required to have excellent corrosion resistance, but also to meet the requirements of other different properties, such as stamping formability, weldability, phosphating and
