摘要
介绍了旋转抗渣试验方法,研究了无碱玻璃对3种含锆耐火材料(熔铸AZS砖、致密锆英石砖和颗粒氧化锆砖)的侵蚀作用,采用该方法对试验后的试样利用SEM和EDAX对其物相组成和显微结构进行了分析。结果表明:无碱玻璃熔体的渗入及含锆耐火材料中的ZrO2的熔蚀是材料蚀损的主要原因;致密锆英石砖由于组成和结构的优化,抗无碱玻璃侵蚀性要优于另外两种砖。
Effect of E-glass corrosion on three kinds of zirconic refractories （electrocast AL2O3-ZrO2-SiO2 brick, dense zircon brick and grain zirconia） was investigated by a gyration slag-resistance method, and phase composition and microstructure of the samples were examined by Scanning Electron Microscope （SEM） and X-ray diffraction. The results showed that corrosion was mainly caused by infiltration of E-glass melt and corrosion of ZrO2, and dense zircon brick revealed better corrosion resistance to E-glass than the others.
