以不同热轧卷取温度生产的典型成分Ti-IF钢冷轧硬卷为研究材料,结合改良森吉米尔法连续热镀锌线的工艺特点,采用Gleeble-1500模拟退火方法和金相、x射线织构测试和硬度测试等分析手段,系统研究了退火过程中试验钢组织、再结晶温度和织构的变化.研究结果表明,随着热轧卷取温度的提高,完全再结晶温度降低;在880℃以下,退火温度对铁素体晶粒度影响很小,热轧低温卷取Ti-IF钢的铁素体晶粒度在11.0级以上,热轧高温卷取Ti-IF钢在lO.5级左右,当退火温度提高到920℃时,晶粒明显粗化;试验钢退火后具有较强的{223}<110>和{114}<110>织构,且热轧卷取温度和退火工艺条件对它们影响较小,随着退火温度的升高,试验钢的{111}织构有增强的趋势,特别是当退火温度较高时,退火温度在920℃时,{111}织构明显增强.
