Feasibility Study on V Fe Alloy Slag as Abrasive Material

The possibility of using V-Fe alloy slag as abrasive material was investigated. The chemical constitution and microstructure of the V-Fe alloy slag were examined. It is found that the slag contains about 90% Al2O3 existing as corundum with high hardness (> 30 GPa) and high bulk density (> 3.6 g/cm(3)). The V-Fe alloy slag can be applied to abrasive material instead of brown alumina (or black alumina).

高钒铁合金渣作为耐火材料的可行性研究与应用

对用攀钢生产的高钒铁合金渣作为耐火材料的可行性进行了研究，并在攀钢耐材公司生产的炉外精炼用耐火材料中得到了应用．结果表明：该合金渣的主要化学成分为Ａｌ２Ｏ３（含量为９０％左右），主要矿物相为刚王，耐火度＞１７９０℃，体积密度＞３．６ｇ／ｃｍ３，可代替特级钒土骨料用于不定形耐火材料的生产。
