摘要:

钢铁企业日常生产中产生的固体二次资源的厂内循环很大程度上加剧了钾钠铅锌等有害元素的富集,特别是对高炉本体危害及冶炼技术指标影响最大的锌元素的排除效率有限。本文对回转窑、转底炉、DK等含锌钢铁固废处理典型生产工艺进行了分析和初步研究,在此基础上提出了钢铁固废全产品化及厂内自循环的工艺路线,不仅可消化钢渣、除尘灰等钢铁固废,拓展了资源利用途径,并可提升产品附加值,为具有类似资源特点的钢铁企业提供借鉴和参考。

Abstract:

The solid secondary resources produced in the daily production of iron and steel enterprises have intensified the enrichment of harmful elements such as potassium, sodium,lead and zinc to a great extent. In particular, the removal efficiency of zinc element,which has the greatest influence on the blast furnace body damage and smelting technical index,is limited,In this paper, the typical production process of solid waste treatment of zinc containing steel in rotary kiln,rotary hearth furnace,DK, etc.,is analyzed and preliminarily studied. On this basis,the process route of full production of iron and steel solid waste and self-recycling in the plant is put forward. It can not only digest steel slag,dust removal and other solid waste,expand the utilization of resources,and improve the added value of products. It provides reference for iron and steel enterprises with similar resource characteristics.
