BD 0.6 Insulation Refractory Brick Mullite Insulating Brick JM23 JM26
The Description:
Shaped light heat insulation firebrick is a type of block heat insulation refractory products with porous structure and thermal insulation properties, among which the production and application of brick shaped products are more widely, so it is also called light heat insulation firebrick. Shaped mullite products mainly refer to mullite light heat insulation, which is a new type of heat insulation material with 50%~80% AL203 content and mullite (3Al203.2Si02) as the main crystal phase and combined phase. Mullite light hot brick has been widely used as the inner lining of kiln working surface in direct contact with flame in recent years because of its high high temperature strength, good high temperature stability, low thermal expansion coefficient and good thermal shock resistance
