Refractory sagger and preparation method thereof
The invention discloses a refractory sagger and a preparation method thereof, and belongs to the technical field of refractories. The refractory sagger is prepared from the following raw materials in parts by weight: 25-35 parts of 30# white corundum, 20-30 parts of 150# white corundum, 15-20 parts of alumina powder and 15-25 parts of kaolin. The refractory sagger formula is simplified, the production cost is accordingly reduced, and sintering carriers available for multiple fields are prepared through the simplified formula, an uncomplicated process and a reasonable matching ratio. The refractory sagger provided by the invention can resist a temperature of 1450 DEG C and can be used repeatedly for more than 90 times or above; in addition, ceramic products have certain stability when being sintered in the sagger, and the white corundum of the ceramic products is not liable to fall off, so that the service life of the sagger is prolonged.
