Unshaped refractory material and preparation process thereof
The invention discloses an unshaped refractory material, which is prepared from 60 to 85 parts of aggregate, 20 to 40 parts of powder, 12.5 to 16 parts of composite binding agent and 0.5 to 2 parts of additive, the aggregate comprises 20-35 parts of high bauxite, 10-30 parts of magnesium aluminate spinel, 10-15 parts of alumina powder, 5-20 parts of silica powder and 3-8 parts of silica powder, the powder contains more than 10% by mass and less than 35% by mass of MgO, and in the powder, the total mass percent of aluminate cement and aluminum dihydrogen phosphate is more than 90% relative to the total mass percent of the powder which is 100%. The admixture is fused quartz particles and is prepared from the following components in percentage by mass: 4%-6% of fused quartz sand with the granularity of 0.3-0.2 mm. According to the unshaped refractory material and the preparation process thereof, the high-temperature resistance of the refractory material is ensured by taking the high-alumina bauxite, the magnesium aluminate spinel and the alumina powder as aggregates, and meanwhile, the red mud, the limestone and the aluminum ash are used as raw materials, so that the preparation cost of the material is greatly reduced, and the practical value of preparation of the material is increased.
本发明公开了不定形耐火材料，包括骨料60‑85份，粉料20‑40份，复合结合剂12.5‑16份和外加剂0.5‑2份；所述骨料包括高铝矾土20‑35份、镁铝尖晶石10‑30份、氧化铝粉10‑15份、硅微粉5‑20份、硅微粉3‑8份，所述粉料含有10质量％以上、35质量％以下的MgO，所述粉料中，相对该粉料整体质量100％，铝酸盐水泥和磷酸二氢铝的总质量％在90％以上，所述外加剂为熔融石英颗粒按照质量配比，由以下成分组成：颗粒度为0.3‑0.2mm的熔融石英砂，含量4％‑6％。该不定形耐火材料及其制备工艺，通过高铝矾土、镁铝尖晶石和氧化铝粉作为骨料保证了耐火材料的耐高温性质，同时原材料使用到赤泥、石灰石、铝灰，极大地降低了材料的制备成本，增加了该材料制备的实用价值。
