Abstract
The present invention provides a supporting brick for a glass kiln, wherein the raw materials comprise, by mass, 50-60% of tabular corundum, 10-20% of alpha-Al2O3 micro-powder, 5-6% of zirconite, 10-15% of mullite, 2-5% of aluminium dihydrogen phosphate, 1-4% of clay, and 2-3% of zirconium dioxide. The supporting brick preparation method comprises: mixing tabular corundum, mullite, zirconite and aluminium dihydrogen phosphate, adding other raw materials and water, carrying out high speed mixing to obtain a mixed material, reducing the pressure in a vacuum box to achieve 140-120 Pa, pressing to obtain a high-density semi-finished product, drying and sintering the semi-finished product, and discharging out from the kiln. According to the present invention, high temperature rapid transformation resistance and chemical component corrosion and wear resistance in a glass liquid are substantially increased, the use age is significantly prolonged, the bubble exhaust time of the glass product is reduced, and the glass corrosion resistance time is prolonged.
