Mullite Insulation Fire Brick
Mullite insulation brick is manufactured with tiny air space similar to honeycomb and the bricks have an excellent insulating property. Mullite insulating bricks can be used in industrial furnace and kilns such as for hot face furnace lining or outer back-up heat lining insulation with features of resisting high temperature and saving heat energy efficiently.
Light Weight Fire Clay Insulation Brick
Fire Clay Insulation Brick can be used in melting furnace, refine equipments, heating equipment, regenerative apparatus, gas furnace, soaking pit, annealing furnace, reaction chamber and other industrial hot working equipment with xcellent performance of high strength, even bulk density, low thermal conductivity and low impurity.
High Alumina Insulation Refractory Brick
High Alumina Insulation Refractory Bricks are mainly used to construct and protect linings of Blast Furnace, Hot Air Furnace, Air Furnace, Reverberatory Furnace and Rotary kiln and etc with high temperature strength, high thermal stability and good chemical slag erosion resistance.
Alumina Bubble Brick
Alumina Bubble Brick is a quality refractory material for resisting high temperature and special demands of positions for furnace and kiln and can be used for service linings in manufacturing high-purity quartz for the electronics industry.
