摘要:
转炉冶炼结束后，熔融态钢渣的温度在1600℃以上，其内蕴含大量的显热，若在高温下充分利用这部分热量，对钢渣进行综合回收利用，不仅可以降低钢渣的排放量，还可降低生产成本、避免资源浪费，具有较好的经济和环境效益。本文提出在添加合适的改质剂以及增加电加热装置的基础上，使用回收有价元素后将余渣直接制成高附加值的有价材料的工艺流程，来进行熔融态钢渣的全面回收利用，将实现熔融态钢渣资源利用的最大化。
After the refining process in the converter, the temperature of molten slag reach to more than 1600˚C, among which there is a large amount of sensible heat. If we make full use of the heat in the high temperature to realize the comprehensive recycling utilization, we can not only reduce the emission of slag, but also lower the production costs and avoid the waste of resources, which can bring better economic and environmental benefits. In this paper, based on adding proper modifier and increase the electric heating device, the use of recovery of valuable elements in the residue directly into high value-added process price materials, comprehensive recovery of the molten steel slag utilization, will maximize the molten steel slag resources utilization.
