Aluminum-magnesium-carbon brick prepared from regenerated tabular corundum and preparation method thereof
The invention discloses an aluminum-magnesium-carbon brick prepared from regenerated tabular corundum and a preparation method thereof. The aluminum-magnesium-carbon brick comprises the following rawmaterials in parts by weight: 15-20 of regenerated tabular corundum 5-3 mm, 25-35 of regenerated tabular corundum 3-1 mm, 10-15 of regenerated tabular corundum 1-0 mm, 8-12 of 97.5 fused magnesite 1-0mm, 0.5-1 of metal aluminum powder 180-mesh, 0.5-1 of metal silicon powder 180-mesh, 0.5-1 of modified silicon carbide powder 320-mesh, 20-25 of 93 brown fused alumina 180-mesh, 2.6-2.8 of 197 crystalline flake graphite and 2.6-2.8 of 710 phenolic resin. The aluminum-magnesium-carbon brick has the advantages that the aluminum-magnesium-carbon brick is high in volume density and low in porosity, slag corrosion resistance and thermal shock resistance of the aluminum-magnesium-carbon brick are improved by replacing 85 high-alumina bauxite with chrome corundum, and cost is greatly reduced by using recycled chrome corundum as a main raw material;.
本发明公开了一种利用再生板状刚玉制备的铝镁碳砖及其制备方法，它包括以下重量份的原料：再生板状刚玉5‑3mm，15‑20；再生板状刚玉3‑1mm，25‑35；再生板状刚玉1‑0mm，10‑15；97.5电熔镁砂1‑0mm，8‑12；金属铝粉180目，0.5‑1；金属硅粉180目，0.5‑1；改性碳化硅粉320目，0.5‑1；93棕刚玉180目，20‑25；197鳞片石墨，7‑10酚醛树脂2.6‑2.8。1)本发明所述的铝镁碳砖的配方，具有较高的体积密度和较低气孔率，采用铬刚玉代替85高铝矾土提高了产品的抗渣侵蚀性能和热震性能，而且采用回收铬刚玉作为主要原料大大降低了成本。
