Corundum-aluminosilicate composite refractory material, and preparation method and application thereof
The invention discloses a corundum-aluminosilicate composite refractory material, and a preparation method and application thereof. The corundum-aluminosilicate composite refractory material comprisesa refractory brick matrix and a high-temperature-resistant coating sprayed on the surface of the refractory brick matrix, wherein the refractory brick matrix is an aluminosilicate shaped refractory brick, and the high-temperature-resistant coating is prepared from, by mass, 60-75% of corundum powder, 5-20% of a binder, 10-15% of a suspending agent and 5-10% of other aids. The raw materials of thehigh-temperature-resistant coating are sprayed on the matrix in a spraying manner to obtain the corundum-aluminosilicate composite refractory material. The material has the advantages of low cost, strong erosion resistance, simple process and huge economic benefit, and is suitable for industrial large-scale production.
本发明公开了一种刚玉‑铝硅酸盐复合耐火材料及其制备方法和应用。所述刚玉‑铝硅酸盐复合耐火材料包括耐火砖基体和喷涂在所述耐火砖基体表面的耐高温涂层；其中，所述耐火砖基体为铝硅酸盐定形耐火砖，所述耐高温涂层的原料，按照质量百分比计，包括：刚玉粉60‑75％，粘结剂5‑20％，悬浮剂10‑15％，其它助剂5‑10％。通过喷涂的方式将耐高温涂层的原料喷涂在基体上，得到刚玉‑铝硅酸盐复合耐火材料。该材料具有成本低，抗侵蚀能力强，工艺简单，具有巨大的经济效益，适用于工业化大规模生产。
