摘要
冷轧优质薄带钢时需多次中间光亮退火，当保护气体不良时会使带钢表面氮化；导致轧制时出现边裂，采用重新退火，进行退氮处理可解决这一问题。
It need several times bright annealing when cold rolling high quality strip steel. If the protect gas is not good enough, the surface of strip may be nitrogen. This will bring out edge crack when strip steel rolling.This problem can be solved by annea- ling again.
