Economical alumina-magnesia carbon brick and preparation method thereof
The invention relates to the technical field of refractory materials, and discloses an economical alumina-magnesia carbon brick and a preparation method thereof. The economical alumina-magnesia carbon brick is prepared from the following raw materials in parts by mass: 50 to 70 parts of sliding plate brick regenerated material particles, 15 to 25 parts of fused white corundum fine powder, 10 to 20 parts of regenerated magnesia carbon material, 2 to 6 parts of crystalline flake graphite, 1 to 3 parts of metal aluminum powder, 1 to 2 parts of glyceryl diacetate and 3 to 5 parts of thermosetting phenolic resin. The preparation method of the alumina-magnesia-carbon brick comprises the following steps: 1, premixing: firstly, premixing the fused white corundum fine powder, the regenerated magnesia-carbon material fine powder and the metal aluminum powder to obtain premixed powder; 2, mixing and grinding: sequentially mixing the raw materials, and mixing and grinding to obtain pug; step 3, ageing the materials; fourthly, forming is conducted, and a green brick is obtained; and 5, baking: placing the green brick in a roller kiln, and carrying out heat treatment to obtain the alumina-magnesia carbon brick. The prepared alumina-magnesia-carbon brick has the characteristics of high strength, excellent anti-scouring performance and the like.
本发明涉及耐火材料技术领域，公开了一种经济型铝镁碳砖及其制备方法，该经济型铝镁碳砖包括以下质量份的原料：滑板砖再生料颗粒50‑70份、电熔白刚玉细粉15‑25份、再生镁碳料10‑20份、鳞片石墨2‑6份、金属铝粉1‑3份、二乙酸甘油酯1‑2份、热固性酚醛树脂3‑5份，该铝镁碳砖制备步骤如下：第一步、预混：首先将电熔白刚玉细粉、再生镁碳料细粉和金属铝粉预混合，得到预混粉；第二步、混碾：将各原料依次混合，混碾得到泥料；第三步、困料；第四步、成型：得到砖坯；第五步、烘烤：将砖坯置于辊道窑中，热处理，得到铝镁碳砖；本发明制备的铝镁碳砖具有高强度、抗冲刷性优良等特性。
