High Temperature Resistant Low Porosity 42% Al2O3 Clay Fire Brick

High Temperature Resistant Clay Fire Brick 42% Al2o3 Low Porosity Fire Clay Brick Price

Clay insulation brick is a kind of quality refractory insulation materials for all kinds of industrial kiln application with various excellent properties of high strength, even bulk density, low thermal conductivity and low impurity. Clay insulation fire brick is produced with top grade fireclay raw materials under the high temperature according to our advance manufacturing technology. Clay insulation block can be used in melting furnace, refine equipments, heating equipment, regenerative apparatus, gas furnace, soaking pit, annealing furnace, other industrial hot working equipment and reaction chamber.

Clay Insulation Brick Description

Clay insulation fire brick is made of fire clay grog as the raw material and plastic clay as the binding agent then adding suitable combustible or foaming agent through firing. clay insulation blocks apparent porosity is high about 40~85% and bulk density is lower than 1.5 g/cm3. Clay insulation fire bricks are mainly used as insulation materials in industrial kiln to reduce heat loss of kiln, save energy and lighten the quality of thermal equipment.

Properties of Clay Insulation Brick

.Low levels of iron and other impurities,
.High refractoriness,
.High porosity, low volume density,
.Good heat insulating effect and energy efficient,
.Good thermal shock stability,
.Corrosion and erosion resistance.

Manufacturing Process of Clay Insulation Brick

Clay insulation bricks are produced from high purity fire clay and binder, by sintering through high temperature. clay insulation blocks are low cost refractory insulation bricks with high performance. Main advantages of clay insulation block are high refractoriness under load, low line expansion coefficients, good thermal shock resistance and strong ability to resist erosion. Which is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity.

Composition of Clay Insulation Brick

Clay insulation firebrick is argillaceous product with about 30~40% Al2O3 content. which is made of 50% soft clay and 50% hard chamotte according to certain granularity need to blend and fired at 1300~1400 ℃ high temperature after moulding and drying. Clay insulation fire brick main mineral composition includes kaolinite (Al2O3·2SiO2·2H2O) and 6~7% impurities (K, Na, Ca, Ti, Fe oxide).
