炼钢生产需要耗用大量脱氧剂,其中以硅铁和铝使用最为普遍。近年来,由于能源紧张,硅铁和铝的供应十分紧缺,不但价格猛涨,还很难得到正常的供应。各炼钢厂为此千方百计试验各种节约铝、硅脱氧剂的新工艺措施,同时也致力于探求合适的能替代硅铁或铝的新型脱氧剂。上海碳素厂根据钢厂的这一需要,与一些钢厂合作,积极开发石墨电极生产过程中的下脚废料碳化硅,替代硅铁合金作炼钢脱氧剂取得成功,具有很大的经济和社会效益。根据上钢三厂等单位的试用表明,以碳 Steelmaking requires the use of a large amount of deoxidizer, of which ferrosilicon and aluminum are most commonly used. In recent years, due to energy shortage, the supply of ferrosilicon and aluminum is very scarce, not only the price soared, but also difficult to get the normal supply. To this end, the steelworks tried every possible means to save the new aluminum and silicon deoxidizer process measures, but also committed to finding a suitable alternative to ferrosilicon or aluminum deoxidizer. According to this need of steel mills, Shanghai Carbon Plant cooperated with some steel mills to actively develop the scrap silicon carbide used in the production of graphite electrodes and succeed in producing steel deoxidation agent instead of ferrosilicon alloy, which has great economic and social benefits . According to the trial of Shangshang Steel Factory and other units showed that with carbon
