High Alumina 7Holes Checker Refractory Brick for Industry Furnace
The Description:
High aluminum brick is aluminum content of not less than 48% aluminum-silicon refractories, raw materials are mainly high bauxite, through raw material mixing, pressing molding, high temperature firing and a series of production processes.
It has the characteristics of good acid resistance, alkaline slag resistance, high refractoriness, high temperature stability and so on.

Product feature:
1. This lattice brick has a vertical straight pipe, which is easy to remove the blocking material.
2. The seven-hole lattice brick should be very strong, especially the upper layer, because it is subjected to high temperature, if there is iron oxide ash deposited here, it will melt with the brick and make the brick lose strength. The strength of brick is related to the thickness of brick. When the brick is thick enough, the center will not heat to the softening temperature.
3. Reduced heat loss.
4. It can ensure that the temperature difference between the inner layer and the outer layer of the furnace top brick is not large.
