Product Description
High alumina lightweight insulating refractory brick for glass furnace block
Insulating fireproof bricks Description
Insulating fireproof bricks are sintered mainly with supper-fine bauxite chamotte, and proper additive by a method of EPS ignition loss, their main advantages include high intensity, low thermal conductivity, excellent thermal stability, very small reheat linear change, outstands erosion and corrosion resistance etc. They are an ideal kind of energy-conserning products which can be widely used as lining or insulating layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry, etc. Recommended service temperature: less than 1400℃.
lightweight High Alumina Refractory Insulating Fire Brick
--Characterized by low bulk density,maximum service temperature is 1350C.
--High cold crushing strengh,size precision and hold the most stable and lowest thermal conductivity of all insulating refractory bricks at present.
--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,productivity and significant economic results can be achieved.
