| 摘 要： | 研究了O’-Sialon－ZrO2－C系材料的抗Al2O3沉积性能，并与Al2O3-C质材料进行了对比。结果表明：O’－Sialon－ZrO2－C系材料的抗Al2O3沉积性能明显优于Al2O3－C质材料，其抗Al2O3沉积机理主要为浇钢温度下O’－Sialon与钢液中夹杂的Al2O3接触并反应生成了低熔相而被钢水冲刷掉，从而阻碍了Al2O3在材料表面的沉积附着。O’－Sialon－ZrO2－C系材料的抗侵蚀能力随材料中ZrO2含量的提高而增强.

| Abstract: | Anti-alumina buildup properties of O'-Sialon-ZrO2-C materials were investigated and compared with that of the alumina-graphite material. The results show that the anti-alumina buildup properties of O'-Sialon-ZrO2-C materials are better than that of the alumina-graphite material. Dispersed alumina in molten steel reacts with O'-Sialon to form a low-melting glass which is eroded away by the molten steel. The slag resistance of the material is inferior to the Al2O3-C material, but, with increase of ZrO2 content in the material, the slag resistance of the materiaI is improved. |
