转炉含磷钢渣循环利用技术的研究现状及展望

 为了实现转炉含磷钢渣高效循环利用,系统分析了转炉含磷钢渣的生产状况、组成成分、磷元素的来源和迁移富集机理、矿相结构以及脱磷技术的研究现状。并以此为基础,通过对转炉含磷钢渣循环利用技术的探讨总结,表明目前的钢渣循环利用技术存在着磷资源利用效率低和钢渣能量损耗大的缺点。因此,依据钢渣磷质量分数高低决定其利用方式并在循环利用环节尽可能降低钢渣能量损失是一种必然的趋势。基于前人的研究基础,进一步对实现低磷渣和高磷渣的高效循环利用进行了展望,从而为钢铁企业提高转炉含磷钢渣循环利用率和降低原料生产成本提供理论依据和技术参考。

Research status and prospect of recycling technology of converter slag containing phosphorus

In order to realize the efficient recycling of converter phosphorus containing steel slag,the production status,composition,source,and migration and enrichment mechanism of phosphorus,mineralogical structure,and research status of dephosphorization technology of converter slag are systematically analyzed.On this basis,through the discussion and summary the recycling technology of converter phosphorus-containing steel slag,it shows that the current steel slag recycling technology has the disadvantages of low phosphorus resource utilization efficiency and large energy consumption of steel slag.Therefore,it is an inevitable trend to determine the utilization mode according to the phosphorus content of steel slag and reduce the energy loss of steel slag as much as possible in the recycling process.Based on the previous research,the prospect of efficient recycling of low phosphorus slag and high phosphorus slag is further prospected,so as to provide theoretical basis and technical reference for iron and steel enterprises to improve the recycling rate of converter phosphorus-containing steel slag and reduce the production cost of raw materials.
