Aluminum-magnesium dry ramming material and preparation method thereof
The invention relates to the technical field of refractory materials, in particular to an aluminum-magnesium dry ramming material and a preparation method thereof, and the aluminum-magnesium dry ramming material comprises the following raw materials in parts by weight: 30-50 parts of fused magnesite; 7-10 parts of anhydrous magnesium sulfate; 8-12 parts of fused white corundum; 7 to 11 parts of active Al2O3 micro powder; 3-4 parts of a complexing agent and a retarder; 4-7 parts of an adhesive; and 3-6 parts of a sintering agent. And a proper amount of titanium dioxide is added, and the heat treatment temperature is favorable for improving the phase, sintering property and mechanical property of the ramming material. By introducing a proper amount of titanium dioxide, reactive sintering of the aluminum-magnesium dry ramming material can be remarkably promoted, and the normal-temperature and high-temperature mechanical properties are improved.
本发明涉及耐火材料技术领域，尤其涉及一种铝镁质干式捣打料及其制备方法，包括以下重量份的原料：电熔镁砂30～50份；无水硫酸镁7～10份；电熔白刚玉8～12份；活性Al2O3微粉7～11份；络合剂和缓凝剂3～4份；粘合剂4～7份；烧结剂3～6份。适量二氧化钛加入量、热处理温度有利于提高捣打料物相，烧结性能、力学性能。适量二氧化钛的引入能显著促进铝镁质干式捣打料的反应烧结，常温和高温力学性能得到改善。
