目前我国钢渣综合利用仍处于较低水平,钢渣中的游离氧化钙导致体积安定性不良,影响其在建筑材料中的应用。本文提出采用还原法分离钢渣中的铁元素,同时利用硅质、铝质等辅助组分调整了尾渣的组成。实验结果表明:钢渣含铁量降低促使其化学组成显著变化,硅质、铝质添加剂对重熔钢渣的安定性有改善作用。 At present, China’s comprehensive utilization of steel slag is still at a low level, the free calcium oxide in the slag leads to poor volume stability, affecting its application in building materials. In this paper, the reduction method is used to separate iron from steel slag, and the composition of tailings is adjusted by using auxiliary components such as silicon and aluminum. The experimental results show that the decrease of iron content in steel slag causes its chemical composition to change significantly, and the addition of silicon and aluminum additives can improve the stability of remelted steel slag.
