冷轧钢卷罩式炉再结晶退火主要任务是将经过冷轧的钢卷进行再结晶光亮退火,以满足用户对钢卷不同力学性能的要求。采用紧卷退火方式,在保护气氛中加热。保护气体一方面作为热介质把热量传递给钢卷,另一方面保护气体H2具有还原性使钢卷表面光亮。但是由于工艺不当及设备故障造成 Recrystallization annealing of cold-rolled coil hood furnace The main task is to recrystallize the bright-annealed coil after cold-rolling to meet the user’s requirements on different mechanical properties of coil. Tight coil annealing method, heating in a protective atmosphere. The protective gas, on the one hand, transfers the heat to the coil as a heat medium and, on the other hand, the protective gas, H2, has a reducing effect so that the surface of the coil is bright. However, due to improper technology and equipment failure caused
