Ceramic combined micro-powder alumina-magnesia carbon brick and preparation method thereof
Belonging to the field of refractory material shaped carbon-containing refractory products, the invention relates to a ceramic bonded micro powder alumina-magnesia carbon brick, which comprises the following raw materials by mass: 50-70% of tabular corundum particles, 2-8% of fused magnesia, 10-30% of fused white corundum fine powder, 1-6% of ceramic bonded micro powder, 4-8% of crystalline flake graphite, 1-3% of metal aluminum powder, and the balance of thermosetting phenolic resin. The preparation method of the ceramic-bonded micro-powder alumina-magnesia carbon brick comprises the following steps: 1, premixing: firstly, pre-mixing the fused white corundum fine powder, the ceramic-bonded micro-powder and the metal aluminum powder to obtain pre-mixed 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 ceramic combined micro-powder alumina-magnesia carbon brick. The prepared alumina-magnesia carbon brick has the characteristics of high strength, excellent thermal shock resistance and the like.
本发明涉及一种陶瓷结合微粉铝镁碳砖，属于耐火材料定型含碳耐火制品领域，包括以下质量百分比原料：50‑70％板状刚玉颗粒、2‑8％电熔镁砂、10‑30％电熔白刚玉细粉、1‑6％陶瓷结合微粉、4‑8％鳞片石墨、1‑3％金属铝粉，余量为热固性酚醛树脂；该陶瓷结合微粉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、陶瓷结合微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，得到陶瓷结合微粉铝镁碳砖；本发明制备的铝镁碳砖具有高强度、抗热震性优良等特性。
