摘要
取向硅钢高温退火的各阶段控制对产品质量至关重要。装炉时钢卷整齐的一面是否与底板接触、钢卷内化合水在特定温度和时间内有无排出干净、高保温阶段有无彻底净化钢质、降温速率和出炉钢卷的温度是否控制在工艺要求范围之内,这些都是高温退火时产品表面和板形质量的控制重点。
Control each of stage of high temperature annealing is central to the quality of oriented silicon steel.These are all key control to surface and shape quality control,such as,whether the neat side contact with the floor when charging,whether the combined water in coil has been cleared at particular temperature and time,whether the impurities have been purified at the stage of high temperature
