Refractory Mullite Insulating Firebricks with 0% MgO Content and 30-60% Al2O3 Content
Refractory mullite Insulating Firebricks /good thermal insulation bricks
Refractory mullite Insulating Firebricks are made from good quality and superpure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chemical demands.
The total weight of the furnace body and walls thickness can be reduced effectively,thermal efficiency and working condition can be improved,energy consumption can be lowered,produtivity and significant economic results can be achieved.
Feature of Refractory mullite Insulating Firebricks
·Light weight brick good for energy conservation.
·Low thermal conductivity and excellent heat resistance.
·Good volume stability at high temperature.
Production Process of Refractory mullite Insulating Firebricks brick:Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment
