摘　　要：介绍了攀钢RH—MFB轻处理LCAK钢和车轴钢 ,自然脱碳和MFB吹氧强制脱碳处理IF钢 ,本处理重轨钢以及MFB加热钢水和真空室的工艺 ,分析讨论了真空降压方式、MFB吹氧对脱碳速度 。The light treatment of LCAK and axle steels,the treatment of IF steel with vacuum decarbonization and vacuum oxygen decarbonization,and the deep vacuum treatment of rail steel and MFB heating molten steel and vessel were carried out in RH-MFB at PZH Steel.the effect of the model of decreasing pressure in the vessel and MFB oxygen blowing was analyzed on the carbonization rate.The influence of the vacuity in the vessel was discussed on the final carbon content in the molten steel.
