摘要：Silicon oxynitride was added in shaped Al2O3-SiC-C refractory material to improve the slag resistance in this paper.Optimum adding quantity of silicon oxynitride powder was also studied. The results show that the slag resistance of Al2O3-SiC-C shaped refractory is improved when 2% or 3% Si2N2O is added. A reasonable amount of Si2N2O added into Al2O3-Si C-C shaped refractory can produce silicon oxide into the slag, which can improve the viscosity of slag and prevent the slag erosion and penetration.
