超快冷工艺对X100管线钢14.8 mm热轧带卷力学性能的影响
试验研究终轧温度790 ~ 850℃,轧后用超快冷与层流冷却相结合,40~60℃/s冷却至580℃,卷取温度380℃时X100管线钢(/%:0.05C,0.25Si,1.97Mn,0.008P,0.002S,0.26Cu,0.36Cr,0.38Ni,0.22Mo,0.03V,0.02Ti,0.09Nb,0.029Als) 14.8 mm热轧带卷的组织和力学性能.结果表明,该钢带卷的晶粒度为13.5级,带状组织0 ~0.5级,组织为粒状贝氏体+马氏体,并含有0.2~0.8 μm马氏体/奥氏体岛,-20℃冲击功265~277 J,具有良好的综合力学性能,满足《天然气输送管道X100螺旋缝埋弧焊管用热轧板卷技术条件》标准要求.
