| 摘 要： | 攀钢在氧气顶吹转炉冶炼重轨钢过程中,熔池中钢水氢含量一直保持在很低的水平,并且在出钢、浇铸等工序中氢含量增加很少其中冶炼终点平均氢含量2.0(旱季)到2.4ppm(雨季),钢水包中2.8ppm,锭模中平均2.1(旱季)到2.3ppm(雨季),与钢水经真空RH处理的水平相当氧气顶吹转炉冶炼和攀枝花地区干旱的自然气候条件造成这种极低的氢含量是攀钢重轨钢无白点现象的主要原因

| Abstract: | The hydrogen content in the molten heavy rail steel is always very low duringmelting by LD process and a slightly increases in tapping and pouring at Panzhihua Iron andSteel Co. The average H_2 content varies from 2.0 (dry season) to 2.4 ppm (rainy season) atsmelting end, 2.8 ppm in ladle and 2.1 (dry season) to 2.3 ppm (rainy season) in ingot mould,which is corresponding to that of the molten steel with RH vacuum process. The low H_2 con-tent in molten steel is the main reason for no flake in heavy rail steel owing to melting by LDprocess and dry climate at Panzhihua region. |
