摘要
采用直流电弧炉处理水淬渣,考察了焦矿比、碱矿比、反应时间以及反应温度对试验结果的影响。在焦矿比12.5%、碱矿比30%、反应温度1350℃±30℃、反应时间3 h的试验条件下,水淬渣中铁还原率达86.04%,实现了锡冶炼过程中水淬渣铁金属二次综合利用。
The granulated water quenching slag is treated by DC electric arc furnace.The effects of coke ore ratio,alkali ore ratio,reaction time and temperature to experimental results are studied.The optimal technological conditions are obtained as following： coke ore ratio 12.5%,alkali ore ration 30%,temperature 1350℃±30℃ and reaction time 3 h.Under above conditions,the reduction rate of Fe is 86.04%.The comprehensive recovery of Fe from tin smelting process is achieved.
