 研究了终轧温度对超低碳Ti IF钢的组织性能和连续退火板织构的影响。试验采用810 ℃、850 ℃、890 ℃和910 ℃4种不同终轧温度。结果表明，终轧温度直接影响退火试样的组织性能和织构特征。在810 ℃和910 ℃低温终轧时，退火组织较均匀，力学性能较好，退火后有利织构ND//{111}显著增强，r值较高。而在850 ℃和890 ℃终轧温度下轧制时，其退火板显微组织不是很均匀，性能和织构特征都相对较差。

Effect of Final-rolled Temperature on Microstructure and Drawability of Ti-IF Steel

The effects of final rolled temperature on microstructure, properties and texture of continuously annealed ultra low carbon Ti IF steel have been investigated. The final rolled temperature was 810 ℃, 850 ℃, 890 ℃ and 910 ℃ recpectively. The results show that there is a close relationship between the microstructure, properties, texture on the one hand and final rolled temperature on the other hand. When final rolling in 810 ℃ and 910 ℃, fine grained microstructure, good mechanical properties were obtained and the annealed texture was enhanced. When final rolling in 850 ℃ and 890 ℃, the annealed microstructure was coarse , properties and texture were not good enough.
