摘　　要：唐钢高强汽车板有限公司开发Ti-IF钢初期,产品出现性能稳定性差、r值波动大的缺点,后通过全流程一贯化管理,实现Ti-IF钢的性能稳定控制,r值优良。具体措施包括:炼钢过程控制微合金元素;热轧过程控制低温加热、高温终轧、高温卷取;冷轧过程控制大的压缩比,并高温退火。Ti-IF steel(Interstitial free steel)has the disadvantages of poor performance stability and large fluctuation of r value of the finished product.Through the whole process of consistent management,it can achieve stable performance control and excellent r value.The specific measures include:controlling microalloy elements in steel-making process;controlling low-temperature heating,high-temperature finishing rolling and high-temperature coiling in hot rolling process;controlling large compression ratio and high-temperature annealing in cold rolling process.
