针对纯氧顶吹转炉法生产中、低碳铬铁工艺中存在炉龄短、耐火材料消耗高的特点,提出了延长转炉炉龄的挂渣法工艺操作。初步论述了此工艺操作的理论依据和炉渣成份对挂渣的影响,以及挂渣的具体操作。根据生产实践认为,采用合理的造渣制度和正确的挂渣法操作,对延长炉龄效果较好。 In view of the short furnace age and the high consumption of refractory materials in the process of pure oxygen top-blown converter production, the technology of extending the furnace furnace age by dross method is proposed. The theoretical basis of the operation of the process and the influence of the slag composition on the dross were discussed as well as the concrete operation of the dross. According to the production practice that the use of a reasonable slagging system and the correct operation of the dross method to extend the furnace better.
