Kam Tai refractory high temperature mullite sagger for sintering powder

1. Description

A corundum mullite sagger production methods, passes through the ingredients, forming and sintering, wherein a weight percentage of ingredients: Fused mullite: 1mm <diameter d ^ 2mm pellet 10- 15% 0. 5mm <diameter d ^ Imm pellets 20-25% tabular alumina 0. 076mm <diameter d San 0. 5_ pellets 20-25% particle size <0. 076mm powder 15 22% 20-25% alumina powder microsilica 0. 5-1 0% calcium aluminate cement plus 0.5 5-1 0% 1-0 hexametaphosphate 0. 3%;... formed using gravity casting forming method; forming method is as follows: (1) the mashing: first alumina powder, silica powder, calcium aluminate cement and tabular alumina fine powder is added in dry mixing compulsory mixer; hexametaphosphate added to water to prepare six partial sodium backup solution; the mixed powder and mix well hexametaphosphate solution, to prepare a slurry; (2) mixing: in the public compound, according to first add a small pellet after pellet was added to increase the order All pellets into the small left foot forming a slurry prepared by mixing; (3) casted: molded model on the vibration table, start shaking table, the slurry was poured into a molding forming model, the edge vibration side pouring off After the mold was semi-finished products.
