摘要
通过介绍日本高强度管线钢的开发现状、工艺现状、各种高强度管线钢的特点以及生产使用情况可以看出,日本管线钢主要生产企业新日铁、JFE和住友公司已确立了高强度管线钢炼钢—轧钢—制管的闭环生产体制,以生产促进研发。其生产的管线钢向高强度、大壁厚、抗大变形和高耐酸性能方向发展,海底管线用钢和耐酸管线钢的强度等级已达到X70,具有优良抗大变形性能的管线钢最高强度级达X120。
Through introduction of development situation, process status and all kinds of pipeline steel with high strength characteristics, as well as production and application. The conclusion showed Japanese main steel marker enterprises such as NSC,JFE and SMI had established mechanic of pipeline steel production course from steel making, steel rolling to pipe manufacture, to boost research by production. Their pipeline steel development orientation with high strength, heavy wall thickness, anti-transformation and resistance to acid corrosion,the strength of ocean pipeline steel and resistance to acid corrosion steel have achieved X70,the top strength of pipeline steel with good anti-transformation characteristic have reached X120.
