【摘要】 研究了浸铝溶胶、锆溶胶镁铬砖的气孔特性变化及对抗渣性能的影响。结果表明:浸溶胶后镁铬砖的气孔率减小、气孔孔径分布变好,确定合适的溶胶浸渍次数为3～4次;浸溶胶会提高镁铬砖的抗渣性能,铝溶胶更能提高材料的抗渣渗透性而锆溶胶则更能改善材料的抗渣侵蚀性。更多还原

【Abstract】 Pore characteristic evolution and slag resistance of magnesia chromite brick impregnated with amumina sol and zirconia sol were studied.The results indicate that the porosity decreases and pore size distribution becomes better after the specimens impregnated with sols.The appropriate impregnation times is 3 or 4.The slag resistance characteristic is improved after the specimens impregnated with sols.Alumina sol can be beneficial to enhance the slag anti-penetration and zirconia sol is better to improve the slag anti-corrosion.更多还原
