Cooperative utilization method of high-iron red mud and molten steel slag
The invention relates to a synergistic utilization method of high-iron red mud and molten steel slag, belongs to the technical field of solid waste utilization, and mainly aims to treat the high-iron red mud and the steel slag and recover molten iron. By adopting the mode of'high-iron red mud drying dehydration + high-iron red mud reduction volatilization roasting + oxygen-enriched molten pool smelting ', the advantages of energy media such as coal gas and steam of a steel plant can be brought into full play, meanwhile, steel slag of the steel plant can be cooperatively treated, red mud and molten steel slag can be cooperatively treated, molten iron and harmless slag are produced, and the purpose of treating waste with waste is achieved.
本发明涉及一种高铁赤泥和熔融钢渣协同利用方法，属于固废利用技术领域，以处理高铁赤泥、钢渣并回收铁水为主要目的，本发明依托钢铁厂处理赤泥，引入有色冶炼系统的富氧熔池熔炼技术，通过采用“高铁赤泥干燥脱水+高铁赤泥还原挥发焙烧+富氧熔池熔炼”的方式，既可以充分发挥钢铁厂的煤气、蒸汽等能源介质优势，同时也可以协同处理钢厂的钢渣，协同处理赤泥和熔融钢渣，产出铁水和无害渣，达到以废治废的目的。
