实验证明,用熔融炉尾气流态化预还原磁选后的转炉渣是可行的。与高炉炉尘一样,在10分钟内,其还原度可达70％以上,满足了终还原的要求。流态化预还原附碳处理后的磁选转炉渣的影响因素的主次顺序为:温度→线速→附碳量→压力。其中线速和温度的影响最为显著,而附碳量的影响不大,这是由转炉渣自身的特性所决定的。 Experiments show that it is feasible to pre-reduce the converter slag after the magnetic separation by using the flue gas of the melting furnace. Like blast furnace dust, the reduction degree can reach more than 70% in 10 minutes, which meets the requirement of final reduction. Pre-reduction of fluidized pre-carbon treatment with magnetic slag converter slag the order of the main factors: temperature → line speed → carbon content with pressure →. Among them, the influence of wire speed and temperature is the most significant, while the effect of carbon content is not significant, which is determined by the characteristics of converter slag itself.
