不锈钢渣的资源处置研究进展

Research Progress on Resource Disposal of Stainless Steel Slag

近年来,我国不锈钢粗钢产量位于世界前列,其在冶炼过程中产生的不锈钢渣逐渐增多,由此造成的资源浪费和环境污染问题日益突出。本文系统介绍了不锈钢渣的资源分布、来源、理化性质、环境污染特性、处理工艺及无害化处置,并综述了不锈钢渣在有价金属回收、水泥、混凝土、微晶玻璃、砖、陶瓷、农业等方面的资源化利用现状,最后简单分析了我国不锈钢渣相关标准和知识产权情况。

In recent years,the output of stainless steel crude steel in China is in the forefront of the world,and the stainless steel slag produced in the smelting process is increasing gradually.So,the problems of resource waste and environment pollution is increasingly prominent.This paper introduces the stainless steel slag recources distribution,sources,physicochemical property,environment pollution characteristics,treatment process and harmless disposal.At the same time,the stainless steel slag in recycling valuable metals,cement,concrete,ceramic glass,brick,ceramics,agriculture and so on,are summarized.Finally,standard and intellectual property of stainless steel slag are analyzed.
