包钢带钢厂450mm热轧窄带钢车间采用较先进的步进式加热炉。1988年以来,对金属部件进行防腐处理,取得显著的技术经济效益。在生产过程中,炉子的水封槽、水冷梁等金属设备处于温度高、废气含硫量高、湿度大等恶劣环境中,加之设计制造上的一些不合理因素,使水封槽、水冷梁等部件大量腐蚀,甚至穿孔,焊缝开裂,漏水严重,被迫频繁 Baotou Steel 450mm hot-rolled narrow strip workshop using more advanced step furnace. Since 1988, the anticorrosive treatment of metal parts made significant technical and economic benefits. In the production process, the furnace water seal groove, water-cooled beams and other metal equipment in the high temperature, high sulfur content in exhaust gas, humidity and other harsh environments, coupled with some of the design and manufacture of unreasonable factors, so that water tank seal, water-cooled beam And other parts of a large number of corrosion, and even perforation, weld cracking, serious water leakage, forced to frequent
