Cement Klin Phosphate Bonded High Alumina Light Refractory Brick
The Description:
Phosphate bonded high alumina brick is a compact or a high bauxite clinker as the main raw material, phosphate solution or aluminum phosphate solution as the bonding agent, after semi-dry press molding, heat treatment at 400~600ºC and made of chemical bonded refractory brick. It is a non-fired brick, in order to avoid large shrinkage of products in the process of use, ingredients generally need to introduce heating expansion raw materials, such as blue stone, silica and so on. Compared with the fired high-alumina brick combined with ceramic, its stripping resistance is better, but its load softening temperature is low, the erosion resistance is poor, so it is necessary to add a small amount of fused corundum, mullite, etc., to strengthen the matrix.
