摘　　要：针对SPCC材质的冷轧罩式退火板料存在冲压裂或起皱、力学性能不合等现象,从热轧原料、冷轧累积压下率和退火工艺及精整方式等研究其对冷轧板力学性能的影响规律,结果表明:Als和C含量,退火温度和退火保温时间对SPCC冷轧罩式退火板屈服强度、抗拉强度和屈强比有显著影响;冷轧累积压下率为77%左右时,延伸率和屈强比相对比较好;随着成品厚度增大,屈服强度、抗拉强度和屈强比呈下降趋势,而延伸率却逐渐升高;平整有利于提高退火板的抗拉强度,降低屈服强度和屈强比。According to phenomenon of the SPCC material cold rolled annealing sheet in stamping crack or wnnkof Yield strength to tensile strength on the SPCC material cold roiled annealing sheet. When cold rolling ratio is 77%, the elongation and Yield strength ing,Yield strength and tensile strength is rise. The leveling is beneficial to ratio. to tensile strength ratio are the better. When thickness of product is thickenand ratio of Yield strength to tensile strength are drop. However,the tlongaimproving the annealing plate tensile strength, lower yield strength and yield
