【摘要】 石墨电极的品种、产量和质量主要受电弧炉炼钢技术的制约，随着大炉容ＡＣ（交流）电弧炉和ＤＣ（直流）电弧炉技术的进步，促使石墨电极向大规格、高功率和超高功率的方向发展。以针状焦作原料，采用容器焙烧、高压浸渍，内串石墨化和专用组合机床加工等新工艺，是生产高品质电极的可靠技术保障。更多还原

【Abstract】 Abstract The kinds,quantities and quality of graphite electrodes are restricted principally by the steelmaking technology.Owing to the technical improvement of AC electric-are furnace and DC electric are furnace with high-capacity,graphite electrodes have been developing toward the direetion of large-specification HP and UHP.It is the use of needle coke as raw material and new technologies,e.g.vessel baking,high-pressure impregnanting longitudinal wise graphitizing and special combining of machine tools etc that is the reliable technology guarantee of the high-quality electrodes.更多还原
