A Fire Brick, Firebrick, Or Refractory Brick Is A Block Of Refractory Ceramic Substance Used In Lining Furnaces, Kilns, Fireboxes, And Fireplaces. A Refractory Brick Is Built Originally To Endure High Temperature, But Will Also Usually Have A Low Thermal Conductivity For Higher Strength Energy. Normally Dense Firebricks Are Utilized In Applications With Extreme Mechanical, Chemical, Or Thermal Stresses, Such As The Inside Of A Wood-Fired Kiln Or A Furnace, Which Is Subject To Abrasion From Wood, Fluxing From Ash Or Slag, And High Temperatures. In Other, Less Hard Conditions, Such As In An Electric Or Natural Gas Fired Kiln, More Permeable Bricks, Usually Known As "Kiln Bricks" Is A Valid Choice. They Are Weaker, But They Are Much Lighter, Easier To Form And Insulate Far Better Than Dense Bricks. In Any Matter, Firebricks Should Not Lose Their Strength So It Should Hold Up Well During Rapid Temperature Changes.

Description Mullite insulation bricks are high alumina refractories mainly made from good quality and pure raw materials.In generally, alumina accounts 65%-75%. Besides mullite,there are also glass phase and christobalite as well as corundum which are good grade fillings. Mullite insulation bricks are widely used for lining in high temperature kilns such as shuttle kiln,roller kiln,glass kiln and petroleum kilns. Specifications 1.Low thermal conductivity, good heat insulation. 2.Low thermal melting point. Lightweight mullite insulating bricks save heat and energy. 3.Low impurity content,high temperature resistance; higher alumina content ensures good performance. 4.Customized shapes to reduce bricks quantity and cost. 5.Dense,compact and accurate structure,low porosity rate. 6.High loading temperature,corrosion resistance. Application Due to its lightweight and good insulating performance,our mullite insulation bricks has broad use for fire resistance lining in heat side and insulating layers, thus increases energy efficiency greatly. Mullite lightweight bricks are popular in hot blast kiln crown,flame side and bottom parts; glass melting furnace regenerator,ceramic sintering kiln,Petroleum cracking system corners and linings,ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.

The bricks we offer are widely applauded for their dimensional stability, compressive strength and durability. Moreover, super heat duty and high alumina fire bricks are the products made from different fractions of refractory grog, fire clays and calcined bauxite of high purity. The different fractions of these raw materials are mixed in counter current mixers and plugged for obtaining homogeneous mixture. The mixture obtained hence, is then pressed in high capacity presses to give the desired shape and size. These pressed shapes are fired in high temperature tunnel kiln at 1300°c and above. The bricks are very light and porous maintaining good extranal temperatures and not allowing heat to radiate from the fire bricks thus increasing in overall furnace efficiencies.These bricks are manufactured as per asme standards and provided to the clients at nominal rates.
