温度对钢渣蒸压粉化性能的影响

钢渣在蒸压条件下的膨胀粉化是改善其稳定性的一个重要方法。通过扫描电镜(SEM)和X射线能谱分析(EDXA),并结合X射线衍射(XRD)、光学显微镜(OM)等检测手段对不同温度下钢渣的微观结构特征进行了分析,分析了微观结构和钢渣蒸压粉化性能之间的关系。结果表明,温度对钢渣的蒸压粉化性能影响明显,钢渣的蒸压粉化率随着烘烤温度的升高,先升高后降低,当预热到1 000℃并保温30 min时蒸压粉化率达到最大值,从而为钢渣的进一步深入研究提供了依据。

Effects of Temperature on Autoclave Pulverization Performance of Steel Slag

The expansion pulverization of steel slag in the autoclave is an important way to improve its stability. In this paper, the scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), X-ray diffraction (XRD), optical microscopy (OM) and other means of detection at different temperatures of the micro-structural characteristics of steel slag are described, analyzed the microstructure and autoclave pulverization of steel slag relationship. The results showed that the temperature on the autoclave pulverization performance of steel slag significantly, so as to further in-depth study of the steel slag provided the basis.
