摘　　要：研究了罩式炉退火条件对Nb+Ti-IF钢性能的影响,通过试验确定了最适合现场生产条件的退火工艺参数。试验结果表明,随着退火温度的升高,Nb+Ti-IF钢的延伸率和n值、r值呈上升趋势,而对其它性能的影响不大。最佳退火温度为740℃,最佳退火保温时间为8 h。The effects of box annealing process conditions on the properties of Nb ＋ Ti - IF steel are studied and the most suitable annealing process parameters for operating conditions on the site are determined based on tests. The tested results show that elongation values and n,r values increase with the annealing temperature increasing, which means that raising the annealing temperature has little effect on other properties of the steel. The best annealing temperature is at 740 ℃ and the optimum holding time for annealing is 8 hours.
