摘要:
通过适当的控轧控冷工艺,太钢在2250热连轧机组上成功开发了极限规格22.22 mm×1 550mm×C 的X70 级热轧卷板,所开发的管线钢30°方向屈服强度达到520 MPa,-20 ℃冲击功达到280 J, 0 ℃平均落锤撕裂面积为90%,性能均达到了试制目标,可用于制造大直径、大壁厚的螺旋埋弧焊管,可承载10 MPa以上的高压输气。
Abstract:
Through appropriate process of control rolling and cooling,the X70 grade pipeline steel of limit thickness 22.22 mm×1 550 mm×C  was developed by TISCO.The yield strength of the coil(30°to the rolling direction) is 520 MPa, the charpy V-notch impact absorbed energy reaches 280J at -20 ℃;the average shear area of DWTT is 90% at 0 ℃.The property of pipeline steel has reached trial production target,and this steel can be made into large SSAW pipe to transport high pressure gas over 10 MPa.
