摘　　要：研究了两种电弧炉钢渣(C钢渣和S钢渣)的微观结构、热稳定性和抗磨损性能,探索钢渣作为太阳能光热发电蓄热材料的适应性。应用同步热分析仪(simultaneous thermal analyzer,STA)研究了钢渣的热稳定性,用HT-1000高温摩擦磨损试验机进行摩擦实验,使用扫描电子显微镜(scanning electron microscopy,SEM)查看微观结构和化学成分,认为C钢渣和S钢渣抗磨损性能良好。The thermal properties,microstructures and wear behaviors of two electric arc furnace(EAF)slag samples(C slag and S slag)were studied.The thermal stability of slag samples were studied by thermogravimetric and differential thermal analyzer.The wear test and tribological behavior were conducted by pin-on-disc rotation tribometer.The microstructure and morphologies of worn surface before and after test were examined by a scanning electron microscopy and energy-dispersive spectroscopy.
