摘要: 摘 要 为推动大宗废弃物和新型废弃物的综合利用,开发热态炉渣余热高效回收和资源化利用技术,以某含钛高炉渣及矿山铁尾矿为原料,利用高炉渣排渣时的高温熔融改性制备微晶铸石,系统研究了不同原料 配比对微晶铸石性能的影响。结果表明:当含钛高炉渣配比为41.7%,铁尾矿配比为58.3%,可得主要晶相为透辉石、辉石,且其耐酸度、耐碱度、抗折强度等性能均达到相应国家标准的微晶铸石产品。通过利用高炉 渣排矿时的余热,将含钛高炉渣与铁尾矿制备微晶铸石产品,为矿山铁尾矿与高炉钛渣的综合利用提供了新思路。

Abstract: In order to promote the comprehensive utilization of large amount of waste and new-type waste and develop efficient recovery and resource utilization technology of hot slag waste heat, titanium bearing blast furnace slag and mine iron tailings were used as raw materials to prepare microcrystalline cast stone by melting at high temperature during slag discharge. The influence of different raw material ratio on the properties of microcrystalline cast stone was systematically studied. The results showed that when the ratio of titanium bearing blast furnace slag and iron tailings is 41.7% and 58.3%, the main crystalline phases are diopside and pyroxene. The titanium bearing blast furnace slag and iron tailings are prepared into microcrystalline cast stone products by using the waste heat of blast furnace slag discharging, which provides a new idea for the comprehensive utilization of mine iron tailings and blast furnace titanium slag.

Key words: titanium bearing blast furnace slag, high temperature melting, microcrystalline cast stone, comprehensive utilization
