摘要
本文研究在冷轧后的低碳钢薄板连续退火工艺中，过效时工序处理制度对组织及性能的影响，确定了过时效期间的冶金过程，最后对比实际生产工艺规程，提出了过时效工序各参数的允许范围。
The effects of overaging process on the structure and properties of continuous annealing low-carbon sheet steel are studied.The metallurgy process during ove raging is determined Finally the allowable scopes of parameters during overaging are proposed in the light of the rules of operation in production line.
