Discussion on Application and Development of High Gradient Magnetic Separation Technology in Steel Industry

摘要

Since entering the 21st century,the environmental pollution trom steel industry has become a hot topic.Because the high gradient magnetic separation (HGMS) technology has high energy utilization rate,no pollution and great economic and social benefits,it has been studied and applied extensively.In China,as the mining of low-grade iron ore is being emphasized,and the waste of resources and environmental pollution are becoming increasingly serious,HGMS technology will attract more and more attention.This article has reviewed the application of HGMS technology in iron ore purification,coal desulfurization,and the treatment of sewage,waste gas and solid waste in steel plants and has forecasted the prospects of this technology's application.%进入21世纪以来,钢铁工业对环境的污染已成为社会的热门话题.由于高梯度磁分离技术能源利用率高、无污染,具有巨大经济效益和社会效益,因此得到广泛研究与应用.在我国,由于低品位铁矿石的开采受到重视,资源浪费及环境污染日趋严重,高梯度磁分离技术的应用将越来越受到重视.本文综述了高梯度磁场分离技术在铁矿提纯、煤脱硫以及钢厂污水、废气和固体废弃物处理等方面运用的现状,并对前景做出了展望.
