摘要
以冶金工业固废为原料制备微晶玻璃为解决冶金固废堆积污染环境问题,推动冶金行业绿色可持续发展提供了有效途径。本文在概述冶金固废制备微晶玻璃两种常见方法基础之上,重点综述了高炉渣、钢渣、赤泥、铁合金渣和粉煤灰等固废共有的SiO_(2)、Al_(2)O_(3)及CaO等基础组分及Fe_(2)O_(3)、Cr_(2)O_(3)、TiO_(2)和稀土氧化物等杂质以及核化、晶化或烧结温度及时间等工艺参数,对以辉石基微晶玻璃为典型代表的微晶玻璃显微结构和理化性能的影响机理的研究现状。此外,对冶金固废微晶玻璃介电特性等功能特性的研究,以及液态钢渣余热利用和微波加热等非常规加热制备技术的应用进行了分析讨论。最后,指出目前冶金固废制备微晶玻璃主要存在问题,并对未来发展方向进行展望。
Preparing the glass-ceramic by metallurgical solid wastes can provide an effective way to reduce the environmental pollution caused by the accumulation of metallurgical solid waste and promote the green and sustainable development of metallurgical industry.This paper will firstly overview two common methods for preparing glass-ceramic from metallurgical solid waste.On this basis,it will focus on the current status of the influence of basic components(SiO_(2),Al_(2)O_(3)and CaO)and the impurities(Fe_(2)O_(3),Cr_(2)O_(3)and TiO_(2))from various metallurgical solid wastes,such as blast furnace slag,steel slag,red mud,ferroalloy slag and fly ash,as well as the process parameters(nucleating,crystallizing and sintering temperature as well as soaking time)on the microstructure and physicochemical properties of glass-ceramics represented by pyroxene-based glass-ceramics.In addition,the research on the functional characteristics,such as the dielectric properties,and the utilization of the waste heat from liquid steel slag as well as the introduction of unconventional heating technologies such as microwave heating are analyzed.Finally,the current problems in the preparation of glass ceramics from metallurgical solid waste are outlined,and the prospects for the future development tendency are forecasted.
