Periclase magnesia-alumina spinel brick and preparation method thereof
The invention discloses a periclase magnesia-alumina spinel brick and a preparation method thereof. The periclase magnesia-alumina spinel brick is prepared from, by mass, 45%-70% of fused magnesite, 6%-30% of magnesia-alumina spinel, 1%-3% of light calcined magnesia, 2%-9% of Al2O3 micro powder, 1%-4% of metal Al powder, 0%-2% of metal Mg powder and 3%-5% of liquid-state phenolic resin binder. The technical problems that energy consumption is large, cost is high, or the content of MgO is high and thermal shock resistance is poor in the production process of the calcined magnesia spinel refractory product in the prior art are solved, and the technical effects of being low in production energy consumption, low in cost and small in pollution of the periclase magnesia-alumina spinel brick are achieved.
