Calcium titanium-aluminate prefabricated part for vanadium smelting reverberatory furnace lining and preparation method thereof
The invention relates to a calcium titanium-aluminate prefabricated part for a vanadium smelting reverberatory furnace lining and a preparation method thereof. According to the technical scheme, 60-75 wt% of calcium titanium-aluminate particles, 10-20 wt% of calcium titanium-aluminate fine powder, 2-7 wt% of titanium dioxide micro powder, 5-10 wt% of alpha-Al2O3 micro powder and 1-6 wt% of rho-Al2O3 micro powder are used as raw materials; 0.05-0.30 wt% of water reducing agent and 3.5-6.0 wt% of water of the raw materials are added; stirring is conducted for 5-8 minutes, vibration forming is achieved, maintenance is carried out for 18-24 hours under the natural condition, demolding is performed, heat preservation is conducted for 18-24 hours at the temperature of 90-110 DEG C, and accordingly the calcium titanium-aluminate prefabricated part for the vanadium smelting reverberatory furnace lining is obtained. The calcium titanium-aluminate prefabricated part has the advantages of being low in production cost, and capable of saving resources and protecting the environment. The obtained calcium titanium-aluminate prefabricated part for a vanadium smelting reverberatory furnace is high in high-temperature strength, good in acidity vanadium slag corrosion resistance and good in permeability.
