IF钢铁素体区热轧工艺参数对深冲性能的影响

 采用润滑轧制，在不同压下率、终轧温度及退火制度下，研究了IF钢铁素体区热轧时，不同工艺参数对IF钢深冲性能的影响。结果表明：在实验范围内，随压下率增加，r值提高；终轧温度下降，r值略微增加；高温退火可使变形铁素体充分再结晶，从而提高r值。ODF织构分析结果与检测结果是一致的。

Effect of Ferrite-Region Hot Rolling on Drawability of IF Steel

The effect of technology data for different reduction, different rolling temperature and annealing temperature on ferrite-region hot rolling of IF steel was researched under the condition of lubrication. The results show that the r-value increase with increasing the reduction, the r-value increases slightly with decreasing the finishing temperature, and the full recrystallization of deformed ferrite can be obtained by high temperature annealing hence r-value is increased . ODF texture analysis result is consistent with the mealsured one.
