Titanium-reinforced corundum refractory material and preparation method thereof
The invention relates to a titanium-reinforced corundum material and a preparation method thereof, and belongs to the field of refractory materials. According to the product, the titanium-reinforced corundum synthetic raw material is prepared from slag obtained after rutile concentrate is reduced by metallic aluminum through regulation and control of chemical components and physical components. The content of Fe in used rutile minerals is high, obtained metal is ferrotitanium alloy, and metal inclusions in slag are reduced through electric smelting. Main chemical components (expressed by positive-valence oxide content) of the product are Al2O3 and TiO2, and the product contains a small amount of MgO, Fe2O3, CaO, SiO2 and Na2O. The main crystalline phase is corundum, and the secondary crystalline phase is titanium trioxide, and other phases are spinel and calcium hexaluminate. The apparent porosity is less than or equal to 10%; and the volume density ranges from 3.5 g/cm < 3 > to 3.9 g/cm < 3 >. The product realizes efficient utilization of slag, and a refractory material with high performance and high application value is obtained. Meanwhile, the material has environmental protection significance and economic value.
