半钢炼钢化渣剂的开发和应用

Development and Application of Slag Forming Agent for Steelmaking With Semi-Steel

针对半钢在冶炼中具有硅、锰等元素生成的氧化物少,成渣困难,吹炼过程热量少的特点,研究了减少渣量、改造渣系结构、提高炉渣冶金能力的方法,制定出3种渣料配比方案。通过对初期渣形成时间、过程冶炼情况、造渣材料消耗、炉渣脱磷、脱硫效果和改造前后终渣成分的对比,3种化渣剂均能缩短半钢炼钢成渣时间,合理调整炉渣碱度,降低渣中FeO含量,改善渣系结构,提高炉渣冶金效果,是半钢炼钢有效的化渣剂。

During semi-steel smelting process, less silicon,manganese are oxidized making. Slag formation difficult. A study was carried out to find suitable technology,which can reduce slag amount,give a new slag system of high metallurgical effect. Thus three slag forming. They set down three agents were tested. The results showed, that all three agents are satisfactory in terms of slag formation time,operation of blowing, consumption of slag forming agents dephosphorization. In this way, the metallurgical effect of slag can be increased by adding such agents to obtain slag with reasonable basicity,low FeO content.
