摘　　要：建立资源节约型、环境友好型企业已成为经济可持续发展的必要前提,钢铁厂含锌含铁尘泥处理技术的开发与研究对促进钢铁企业节能降耗具有重要意义。对宝钢来说,每年产生150万t左右的含锌含铁尘泥,如何高效地回收其中的有益元素,去除有害元素,是当前面临的一项紧迫任务。本文通过比较目前业已成熟的转底炉和竖炉两大工艺,为宝钢今后处理含铁含锌尘泥工艺方案的选择提供了思路。Building resource-conserving and environmental fi＇iendly enterprise is a precondition for the sustainable development of the economy, the development and research of treatment technology for zinc and iron containing dust and sludge in iron and steel plant are of significance for promoting energy-saving and cost-reducing of iron and steel enterprises. How to effectively recover the useful compositions and remove harmful elements from 1,500,000 tons dust is an urgent task for Baosteel sintering. By comparing such two major processes as RHF and shaft furnace at present, idea was provided for future selection of Baosteel zinc and iron containing dust and sludge treatment schemes.
