摘要
介绍了首钢27.5mm厚X80管线钢的成分设计和控轧控冷工艺,以及成品组织形貌,测定了厚壁X80钢板的低温韧脆转变曲线,并分析了控轧控冷工艺对大壁厚X80钢板低温韧性的影响。
The composition,controlled rolling and controlled cooling process for 27.5mm X80 linepipe steel of Shougang were introduced.Meanwhile,the ductile-brittle transition curves were measured,and the influence of controlled rolling and controlled cooling process on the low-temperature toughness of thick-wall X80 plate was analyzed.
