Refractory brick and preparation method thereof
The invention discloses a refractory brick and a preparation method thereof. The refractory brick is prepared from, by weight, 50-60% of fused magnesia particles, 0-15% of fused magnesia powder, 0-20% of fused spinel particles, 0-20% of fused spinel powder, 0-9% of fused spinel micro powder and 1-6% of compound admixtures; secondary spinel is generated through the amphigama of the fused spinel micro powder and sintering activity in the high-temperature use process, volume expansion caused by an electric smelting method or a sintering method is avoided, and the medium-temperature strength and normal-temperature strength are improved; the critical grain size of the components is increased, a firm framework structure is provided for the refractory brick, and high-temperature strength is improved; the refractory brick and the preparation method thereof are used for solving the technical problem that in the prior art, an refractory brick cannot integrate environmental protection and strength; the refractory brick is environmentally friendly and high in strength.
