Φ350～Φ500mm准超高功率石墨电极生产

Manufacture of Φ350～Φ500mm quasi-ultra high power graphite electrodes

准超高功率石墨电极性能介于超高功率石墨电极和高功率石墨电极之间,其性能指标接近超高功率石墨电极,既能满足超高功率精炼炉和高功率电弧炉炼钢对石墨电极的要求,而生产制造成本较超高功率石墨电极有较大幅度地降低,又能有效降低炼钢成本。本文对山西晋能集团大同能源发展有限公司炭素分公司使用3种国产石油焦煅烧焦分别与进口高级、普通级针状焦按一定比例相配比生产Φ350～Φ500mm准超高功率石墨电极进行介绍。成品检验结果表明,研制的准超高功率石墨电极各项理化指标均接近超高功率石墨电极,可满足超高功率精炼炉的生产需要。

The properties of quasi- ultra high power graphite electrodes are between the high power graphite electrodes and ultrahigh power graphite electrodes, close to those of ultra- high power graphite electrodes, which can meet the demand of ultrahigh power graphite electrodes for LF and high power graphite electrodes for electric arc furnace, and reduce the cost of the production of high power graphite electrodes and ultra high power graphite. The technologic processes for φ350- φ500mm quasi -ultra high power graphite electrodes were introduced, which were made from imported high-ranking/ordinary needle cokes to a scale in Shanxi Jinneng Group Datong Energy Development Co., Ltd, Carbon Branch. The results show that the properties of products obtained are close to those of ultra- high power graphite electrodes, and can meet the demand of utra- high power graphite electrodes for LF.
