Product Description
INSULATING FIREBRICK
Luyang Insulating Firebrick is made from high-purity refractory powder and organic fillers which burn out during manufacture to
give a uniform and controlled pore sture. The brick is compressed in vacuum and sintered under high temperature. Luyang Insulating
Firebrick is widely used as hot face refractory lining or back-up insulation in various kinds of industrial furnaces.
Features
Excellent thermal shock resistance
Accurate and customized dimension
High crushing strength
Low thermal conductivity
Low heat storage
Typical Applications
Metallurgy industry
Petrochemical industry
Ceramics industry
Aluminum industry
Glass industry
