Light refractory brick for high-temperature furnaces
The invention discloses a light refractory brick for high-temperature furnaces. The light refractory brick for high-temperature furnaces is prepared by the following steps: (1) burdening: selecting sulfur residue powder, clay, a pore forming material and alumina as raw materials, wherein the proportion of the sulfur residue powder to the clay is 1.1-1.3, the pore forming material is a mixture of saw dust and polyvinyl chloride balls, the addition of the saw dust is 12-14% of the total weight of the sulfur residue powder and the clay, the addition of the alumina is 10-15% of the total weight of the sulfur residue powder and the clay and the addition of the polyvinyl chloride balls is 1-2% of the total weight of the sulfur residue powder and the clay; (2) mashing; (3) mixing by using a secondary mixing process; (4) ageing the mixture; (5) sintering at 1400-1500 DEG C; (6) preserving the temperature for 4-6h; (7) molding; (8) maintaining. The light refractory brick for high-temperature furnaces is relatively high in cold crushing strength and thermal shock resistance frequency and good in heat-conducting property.
