摘　　要：本文研究了连续温火工艺对深冲钢机械性能的影响。结果表明，均热工艺为８５０℃ × ８０ｓ或８７０℃×４０ｓ时延伸率最高，８７０℃×８０ｓ时屈服强度最低，一次冷却速度影响不明显；过时效工艺对强度影响不明显，３７０℃时效１８０－３００ｓ时延伸率较高。The effects of continuous annealing process on mechanical properties of deep drawing steel sheet are studied. The best elongation is obtained when soaking at 850 ℃ 80 s or 870 ℃ 40 s. and yield strength is the lowest when soaking at 870 ℃ 80 s. Primary cooling rate has no distinct effect. The averaging process has no obvious effect on the strength of deep drawing steal. the elongation is best when ov eraging at 370 ℃ and in the time range of 180~300s.
