安钢高炉渣的性能及利用研究

STUDY ON THE PROPERTY AND APPLICATION OF ANGAN BF SLAG

介绍了安钢高炉渣的产生和处理方法,利用X荧光光谱仪、X-Ray衍射(XRD)、差式扫描热量分析(DSC)、多点氮气吸附法(BET吸附法)、激光粒度分析仪及扫描电镜(SEM)对安钢高炉渣的化学组成、物化特性,热学特性以及微观结构进行了研究和分析。结果表明安钢高炉渣是以CaO、A l2O3、S iO2、MgO等为主要成份的玻璃体物质,晶化温度在930℃;炉渣粒度以小于5mm的为主,不同时间的球磨粉碎将使炉渣粒度和比表面发生变化。以安钢炉渣为主要原料,经过晶化、烧结等工艺可制得性能优良的微晶玻璃材料。

Production and treatment method of Angang blast furnace slag were introduced in this article. Chemical composition, physical characteristic, thermal characteristic and microstructure of Angang blast furnace slag were studied by X -ray Fluorescence Spectrometry, X -ray diffraction, DSC, BET adsorption, Laser granularity analyzer and SEM. The results show that the main constitution of Angang blast furnace slag is glass phase composition with CaO, MgO, Al2O3, SiO2, and the crystal temperature is 930℃. The grain size of Angang blast furnace slag is mostly less than 5mm. The grain size and surface area of blast furnace slag will change with different ball milling time. High quality glass - ceramics have been prepared after being crystallized and sintered by using Angang blast furnace slag as main materails.
