冷轧家电板是冷轧高端产品之一,屈服强度达到280 MPa以上的高强度家电板越来越受到用户青睐,本文针对罩式退火工艺生产高强度家电板实践中遇到的问题进行探讨分析,得出通过提升退火均匀性并结合平整延伸率的控制能够使强度级别达到用户要求,而对于表面活性及下游磷化或陶化过程中的锈蚀问题,不宜采取调整原料成分的方式,而应调整清洗剂、平整液。
Cold-rolled household appliances is one of the high-end cold-rolled products, the yield strength of more than 280 MPa of high-strength appliance board more and more favored by users, this paper for the hood annealing process of production of high-strength appliance board in the practice of the problems encountered in exploration and analysis , Obtained by improving the uniformity of annealing combined with the control of the formation of elongation to the intensity level to meet user requirements, and for the surface activity and downstream phosphating or ceramic process of rust, should not be taken to adjust the composition of raw materials, but should Adjust cleaning agent, leveling fluid.
