摘　　要：影响超低碳冲压产品性能的因素较多,文章摸索了不同强化元素含量、退火温度等参数及平整工序对冲压产品性能的影响规律,结果表明:随着碳、锰、磷含量的增加,产品屈服强度呈上升趋势,且碳含量对不同厚度的产品影响程度存在差异;随着退火段温度升高,产品主要经历回复、再结晶形核、晶粒长大三个阶段;退火段钢带运行速度降低,抗拉强度随之降低。There are more factors influencing the performances of ultra low carbon stamping products.In this paper,the influence rule of such parameters as contents of different strengthening elements and annealing temperature as well as levelling process on the performances of stamping products is explored.The results showed that the yield strength of product tended to increase with the increase of contents of carbon,manganese and phosphorus as well as the influence degrees of carbon content on the products with different thicknesses were different;with the increase of annealing temperature,the products mainly underwent such three stages as reverting,recrystallization nucleation and grain growth;tensile strength decreased with the running speed of steel strip in annealing decreased.
