Method for producing a refractory material from aluminum residues

A method for making a refractory material comprising the steps of:

• providing aluminum residues of aluminum recycling;
• providing carboxylmethyl cellulose adhesive solution;
• mixing the aluminum residues with the adhesive solution so that the adhesive solution takes up 5 wt % to 10 wt % of the mixture;
• granulating the mixture into grains;
• filling the grains in a mold;
• pressing the grains with a uni-axial compressive force in the mold into a green body;
• moving the green body from the mold;
• and
• calcinating the green body at 1100° C. to 1400° C. in a furnace, thus sintering the green body into a refractory material,
• wherein the resulting refractory material has a composition in weight percent of 63.52 to 80.8% Al2O3, 12.19 to 30.84% SiO2, 3.66 to 4.44% MgO, 0.54 to 1.05% Fe2O3, 0.56 to 0.72% CaO, 0.33 to 0.56% Na2O, 0.36 to 0.49% K2O, 0.06 to 0.2% CuO, and 0.03 to 0.07% Cr2O3.
