在实验室条件下,对CSP流程供原料生产的冷轧低碳钢板进行不同慢速升温速度(30～50℃/h)和不同保温温度(660～700℃)的模拟退火试验,对试样的性能和织构进行测量,分析温度制度对成品板的性能、组织和织构的影响.结论认为,为使CSP流程供料的冷轧深冲板获得良好的性能和织构,当保温温度为680℃保温10 h时.慢速升温速度应控制在40℃/h左右;当慢速升温速度为35℃/h,保温10 h时,保温温度应控制在680～700℃.退火后成品板γ取向线上{111}<110>织构和{111}<112>织构的取向分布密度差随升温速度的增大而减小,但基本不受保温温度影响.
Under laboratory condition,influences of different heating rates(30-50℃/h)and different annealing temperatures(660-700℃)on properties and textures of cold rolled deep-drawing sheet produced by CSP process were investigated.The results show that when annealing temperature is 680℃,and holding time is 10 h,the heating rates should be controlled in the range from 40℃/h to 30℃/h;when heating rate is 35℃/h and holding time is 10 h,the annealing temperature should be controlled in the range between 680℃ and 700℃.The difference of orlentation distribution density of{111}<110>and(111}<112>texture decreases as the heating rates increase,but is not affected obviously by annealing temperature.
