宁钢钢渣资源化利用的创新与实践

Innovation and practice of recycling utilization of steel slag in Ningbo steel

钢渣是钢铁工业的主要固体废物,目前我国有效综合处理率仅为30%,大量的钢渣堆积造成资源浪费、环境污染。宁钢在转炉钢渣滚筒法处理、渣钢磁选提取、尾渣生产钢渣微粉等工作中积极创新与实践,率先实现钢渣低成本高效率零排放,钢渣100%循环利用,社会效益和经济效益显著。

Steel slag is the main solid waste in the steel industry. At present, the effective comprehensive treatment rate in China is only 30%. A large amount of steel slag is accumulated, resulting in waste of resources and environmental pollution. Ningbo steel actively innovates and practices in the work of converter steel slag hot and suffocating, slag steel magnetic separation and tail slag production of steel slag powder, taking the lead in achieving low cost and high efficiency zero discharge of steel slag, 100% recycling of steel slag, social benefits and economic benefits significant.
