By used pre-treatment technology,recycling technology,and end resource utilization technology to treat converter steel slag,achieving full utilization of converter steel slag.The pre-treat-ment technology of converter slag and desulfurization slag separates slag steel and slag iron,which were respectively used as raw materials for steelmaking and ironmaking,achieving the recycling of iron con-taining materials.Adding 1.93%tailings instead of flux in the sintered ore ensures the stability of sin-tering economic and technical indicators.By using the KR desulfurization slag hot cycle utilization technology,the iron temperature was only reduced by about10℃,and the consumption of desulfurizer was reduced by about 40%.Based on the physical and chemical characteristics of steel slag tailings,products such as steel slag micro powder,all solid waste cementitious materials,roadbed materials,and unburned bricks have been developed,improving the utilization rate and added value of tailings,and achieving cross industry collaborative utilization of steel slag tailings.
