High Alumina Insulation Bricks

High-alumina insulation refractory bricks have the characteristics of low bulk density, low thermal conductivity, excellent thermal insulation performance and stable quality. They can be used for the lining or insulation layer of various high-temperature furnaces. In addition to meeting the internationally adopted mechanism one-time molding and burning additive manufacturing process, our factory also retains the traditional foam lightening method and casting molding. The cross-sectional structure of the product is uniform, and the pores form a complementary and interpenetrating honeycomb, so that the product's compressive strength and thermal insulation performance are both up to the international level. All product shapes are ground and shaped, with small dimensional deviations, which can meet the special requirements of furnace masonry.

High-alumina insulation bricks are insulation refractory products made of bauxite as the main raw material, with an aluminum content of not less than 48%. The production process adopts the foam method. The burning additive method can also be used. The bulk density at the load softening temperature is 0.5-1.2g/cm3, and the thermal conductivity is 0.2-0.5W/(m.k).
