Embodiment 1
[0040] Embodiment 1 A kind of pavement brick for glass kiln
[0041] Formula: 30 parts of natural zircon sand, 30 parts of alumina powder, 1.6 parts of soda ash, 1.5 parts of fluorite powder, 2 parts of silica powder and 8 parts of titanium dioxide.
[0042]Preparation method: specifically comprise the following steps:
[0043] (1) Mix the components in the formula dosage evenly in proportion, then heat and melt in an electric arc furnace to obtain a molten liquid, and cast the molten liquid into the sand mold of the incubator at 1820°C;
[0044] (2) The molten solution is insulated and annealed in an incubator for 12 days and then out of the case to obtain the rough product of the paving brick;
[0045] (3) After the rough product obtained in step (2) is sand-cleaned, the riser is cut and each surface is ground, it is packaged to obtain the finished paving brick.
[0046] The insulation box described in step (1) and step (2) is filled with insulation material, and the insul...
