摘要

叶片钢1Cr12Ni2Mo2VN电极坯母材（/%:0.10C，0.24Si，0.81Mn，0.013P，0.002S，11.75Cr，2.63Ni，1.70Mo，0.32V，0.033N）的生产流程为30 t EAF-VOD-LF-2.67 t铸锭-退火-Φ250 mm锻坯。通过将ANF-6二元渣改成高纯度、低杂质NEUD06预熔四元渣

平均熔速由5.27 kg/min降低至3.5~4.0 kg/min等工艺措施

成功地生产出Φ430mm叶片钢1Cr12Ni2Mo2VN电渣锭（/%:0.10~0.12C，0.75~0.86Mn，0.21~0.24Si，0.011~0.014P，0.0001S，11.76~11.82Cr，2.54~2.61Ni，1.63~1.71Mo，0.31~0.32V，0.039N）。检验结果表明，电渣锭的组织为马氏体+0.5%~1.5% δ-铁素体，非金属夹杂物总和为1.5~2.0级，[O
