| 摘 要： | 研究了O′－Sialon/BN和O′－Sialon/ZrO2复合材料抗溶融金属和保护渣侵蚀，结果表明：O′－Sialon/BN复合材料抗钢水侵蚀的动力学分为两段控制：前期为界面化学反应控制，后期为扩散控制，O′－Sialon/ZrO2复合材料具有良好的保护渣侵蚀性能，这是由于ZrO2在硅酸盐溶体中的溶解度较低，随着ZrO2的增加，抑制了O′－Sialon与CO，以及渣中其他组元的反应，从而提高了O′－Sialon抗的侵蚀性。

| Abstract: | Erosions of O'-Sialon/BN in molten Steel and O'-Sialon/ZrO2 in protective slag of continuous casting were investigated. According to eperimental results and theoretical analysis, erosion kinetics of the O'-Sialon/BN in molten steel was controlled by tWo steps: the first one is controlled by a chemical reaction taking place on the interface; the second one is controlled by diffusion through boundary layers. The O'- Sialon/ZrO2 composites had good erosion resistance to continuous casting protective slag because the solubility of ZrO2 in silicate melt is limited and the increment of ZrO2 content will prevent O'-Sialon from reacting with dissolved CO and other components in slag. |
