Low heat conduction Heat Insulation Refractory Fire clay insulating brick For Thermal Boiler
Fire Clay insulation brick refers to light refractory products containing Al2O3 30%-46%, which is mainly based on clay clinker or light clinker and plastic clay. It is usually produced by combustible method, or porous structure can be formed by chemical method or foam method. Production process characteristics The insulating refractory is characterized by high porosity, generally 40%-85%; low bulk density below 1.5 g/cm3; low thermal conductivity, generally below 1.0 W (m.k). It can reduce heat loss, save energy and reduce the quality of thermal equipment. The mechanical strength, wear resistance and slag erosion resistance of heat insulation refractory are poor, so it is not suitable for the load-bearing structure of kiln and direct contact with slag, charge, molten metal and so on.Advantage reduce heat loss,

ApplicationFire Clay insulation brick is widely used, mainly used in various industrial kilns without contact with molten matter and no corrosive gas insulation material, using temperature of 1200-1400℃. Mainly used in thermal boiler, glass kiln, cement kiln, chemical fertilizer gas furnace, blast furnace, hot blast furnace, coking furnace, electric furnace, casting and pouring steel brick. clay insulation bricks can also be used as thermal surface refractories or other refractories to support thermal insulation, for melting furnaces, firing kilns, flues, refining units, heating units, regeneration units, gas furnaces and pipes, equalizing furnaces, annealing furnaces, reaction chambers and other industrial thermal equipment.Service: We have our own factory with advanced technical equipments, complete production lines from raw material to delivery.
