摘要/Abstract

摘要： 珠钢用150 t EAF-LF-50-60 mm板坯连铸机-热连轧工艺和Nb-Ti复合微合金化技术开发了9．50 mm带X60管线钢 (％:0．03～0．07C,1．2～1．6Mn,Nb+V+Ti≤0.15)。检验结果表明,钢带组织为铁素体+少量珠光体,晶粒度11．5～12．0级,带状组织≤1．5级,屈服强度440-505 MPa,0℃夏比冲击功为140～270 J,其综合性能满足API-5L技术标准和工程使用要求。

Abstract: The 9.50 mm strip of X60 pipeline steel (0.03~0.07C,1.2~1.6Mn,Nb+V+Ti≤0. 15)has been developed by 150 t EAF-LF-50~60 mm cast slab-hot continuous rolling process and Nb-Ti compound-alloying technology at Zhujang Steel. Examination results showed that the structure of strip was ferrite + minor pearlite with grain size rating 11.5~12.0 and banded structure rating ≤1.5, the yield strength of was 440~505 MPa, charpy impact energy at 0 ℃ was 140~270 J. Its comprehensive properties meet the requirement of API-5L technical standard and engineering application.
