中文摘要：
分别以98电熔镁砂和95烧结镁砂为原料，按骨料与基质料的质量比70：30配料，并外加不同量环保型无机结合剂Na2SiO3·9H2O制成试样，200℃=3h烘干后，分别于1100℃3h和1550oC3h进行热处理。通过常温性能检测、显微结构观察，研究了镁砂原料的种类及结合剂Na2SiO3·9H2O的添加量（质量分数分别为4％、5％、6％、7％）对镁质干式料性能的影响，并采用静态坩埚法评价了试样的抗渣性能。结果表明：（1）以电熔镁砂为原料的试样，其常温物理性能优于烧结镁砂的；（2）结合剂Na2SiO3·9H2O的适宜添加量为5％；（3）Na2SiO3·9H2O结合的试样其抗渣性能优于酚醛树脂结合的；（4）渣蚀过程以渗透为主，在渗透的过程中，方镁石与熔渣反应，使熔渣的黏度增大，减缓了其进一步渗透。
英文摘要：
Magnesia based dry vibration mix was prepared using fused magnesia and sintered magnesia as the main staring materials, respectively,environmental friendly inorganic salt Na2SiO3·9H2O as binder. The mass ratio of aggregate and matrix is 70：30. After dried at 200 ℃ for 3 h,the specimens were fired at 1100 ℃ and 1550℃ for 3 h. Effects of magnesia type and additions （4% ,5% ,6%,7%,repectively） of Na2SiO3·9H2O on the properties of the specimens were investigated by testing the physical properties, observing the microstructure of the specimens, and slag resistance of the specimens were evaluated by static crucible test. The results showed that. （1） the physical properties of the specimen with fused magnesia were better than those with sintered magnesia; （2） the optimum addition of Na2SiO3·9H2O was 5% ; （3） the slag resistance of the specimen bonded by Na2SiO3·9H2O was better than that bonded by phenol resin; （4）the main corrosion of the slag to specimen was penetration. Because of the periclase dissolution into molten slag, increasing the viscosity of the slag ,the further penetration of the slag was retarded.
