摘要: 研究了O'-Siaion/BN和O'-Sialon/ZrO₂復合材料抗熔融金屬和保護法侵蝕.結果表明:O'-Sialon/BN復合材料抗鋼水侵蝕的動力學分為兩段控制:前期為界面化學反應控制,后期為擴散控制.O'-Sialon/ZrO₂復合材料具有良好的抗保護渣侵蝕性能這是由于ZrO₂在硅酸鹽熔體中的溶解度較低,隨著ZrO₂的增加,抑制了O'-Sialon與CO,以及渣中其他組元的反應,從而提高了O'-Sialon抗渣的侵蝕性.

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.
