单垛式罩式退火炉是一种利用保护气氛(3～5％H_2,95～97％N_2)作导热介质,对冷轧薄板进行间接加热的再结晶式光亮退火设备。其作用是消除带钢经过冷压力加工后所产生的材质硬化,以满足用户对产品质量的各项技术要求。因此,从技术上、工艺规范上、设备上和管理上,对罩式炉的生产全过程予以科学的控制是非常重要的。不然,就会使钢卷出现退火缺陷,如氧化问题。一旦带钢表面形成了氧化膜,必然给用户再加工带来麻烦(如喷、涂、镀等工艺)。当然,
The single stack annealing furnace is a kind of recrystallization annealing equipment which utilizes the protective atmosphere (3-5% H 2, 95-97% N 2) as the heat transfer medium to indirectly heat the cold-rolled sheet. Its role is to eliminate the strip after the cold-pressed material hardened to meet the user’s product quality of the technical requirements. Therefore, from the technical, technical norms, equipment and management, the whole process of production of the hood furnace to the scientific control is very important. Otherwise, there will be annealed defects in the coil, such as oxidation problems. Once the strip formed on the surface of the oxide film, will inevitably bring trouble to the user re-processing (such as spray, coating, plating and other processes). of course,
