Al2O3-ZrN-Sialon-C复相耐火材料抗渣侵性能研究
Slag Corrosion Resistance of Al2O3-ZrN-Sialon-C Refractories
摘要
Abstract
Al2O3-ZrN-Sialon-C refractories were prepared using tabular alumina,graphite,α-alumina,metallic aluminium powders,silicon metal powder,ZrN-Sialon composite powder as raw materials,phenolic resin as binder.Effect of ZrN-Sialon composite powder additions on slag corossion resistance of Al2O3-ZrN-Sialon-C refractories were studied with static crucible method.Microstructure and composition analysis of corroded refractory were carried out by Scanning Electron Microscopy(SEM)and Energy Dispersive X-ray Spectroscopy(EDS).The reaction mechanism between slag and refractory was analyzed by thermodynamic analysis.The results show that with the ZrN-Sialon composite powder addition of 9wt％,the Al2O3-ZrN-Sialon-C refractories have the optimal slag corossion resistance.The thermodynamic analysis indicate that the SiO2 and ZrO2 which is formed due to the oxidation of Sialon and ZrN could effectively decrease the apparent porosity of material that prevent the further slag corrosion and penetration.The reaction mechanism between slag and refractory is oxidation-corrosion-penetration.关键词
