Product introduction of mullite insulation brick JM26
Mullite insulation brick as a good refractory raw material, this kind of mineral is relatively rare, aluminum silicate at high temperature generated minerals. Mullite can be made of various types of medium insulation brick, heat insulation effect is good, has been successfully used in many industries.
Features of mullite insulation brick JM26
Lightweight Mullite brick is a new type of energy-saving refractory material, can directly contact the flame, with high temperature resistance, high thermal shock stability, high strength, low thermal conductivity and other characteristics.
Application of mullite insulation brick JM26
Light weight mullite insulation brick is mainly used in hot blast furnace top, blast furnace body and bottom, glass furnace regenerator, ceramic sintering kiln, oil cracking system lining and so on.
More relevant refractory products: Ceramic fiber blanket
