Low-temperature fired titanium-rich corundum composite silicon carbide brick and preparation method thereof

The invention discloses a low-temperature fired titanium-rich corundum composite silicon carbide brick and a preparation method thereof. The titanium-rich corundum composite silicon carbide brick is prepared from the following raw materials: 3-1mm brown fused alumina, 1-0mm brown fused alumina, 3-1mm titanium reinforced corundum, 1-0mm titanium reinforced corundum, 200-325 meshes titanium reinforced corundum, 200-325 meshes silicon carbide, silica fume, metal silicon micropowder and binding clay. In addition, a binding agent is added. Aggregate in the ingredients is mixed, and a mixed material A is obtained; mixing the fine materials to obtain a mixed material B, adding the mixed material A into the mixed material B, and mixing to obtain a total mixed material; and sequentially carrying out compression molding, drying and sintering on the total mixed material to obtain the titanium-rich corundum composite silicon carbide brick. The product provided by the invention has the characteristics of low firing temper
