通过Nb+Ti IF钢在1700mm机组上进行的铁素体区热轧试验,表明在现有设备能力条件下,此钢完全可进行铁素体区轧制,若在较高温度(720℃)下卷取,则钢卷中部的伸长率将能达到53%。
The hot rolling of ferrite zone on 1700mm unit by Nb + Ti IF steel shows that the steel can be completely ferritic rolled under the existing equipment capacity. If the temperature is higher than 720 ℃, Under the coiling, the elongation of the middle of the coil will be able to reach 53%.
