What Are The Characteristics Of Special Phosphate Bonded High Alumina Brick

The special phosphate bonded high aluminum composite brick is developed and produced on the basis of the production process of phosphate high aluminum brick. It is composed of a wear-resistant working meal and a light heat insulation layer. The density of the wear-resistant layer is greater than 2.80g/cm3, and the strength is greater than 80MPa; the density of the light insulation layer is less than 1.9g/cm3, and the strength is greater than 25MPa. The organic combination of the two makes the special phosphate bonded high aluminum composite brick have more remarkable characteristics than the phosphate high aluminum brick. It not only retains the original good wear resistance and thermal shock resistance, but also increases the good heat preservation and energy saving effect, reduces fuel consumption, reduces the load of the kiln body, and reduces heat loss.
