Product Introduction
Mullite insulation bricks are mainly used in the linings of various high-temperature furnaces for insulation, in order to improve the insulation effect of high-temperature furnaces and reduce energy consumption.
Product Advantage
- The lightness of mullite insulation brick is its remarkable characteristic. Its low density reduces the weight of the furnace, reduces the burden on the furnace structure, and makes installation and maintenance easier.
- Mullite insulation brick can also directly contact the flame without the need for an additional protective layer, further simplifying the furnace structure and saving costs.
