Insulation Bricks are used for hot face & back up insulation lining of Boiler, Reheating furnace, Blast furnace, reactor chamber, high temperature furnace etc. Insulation Bricks are providing energy efficiency by minimising heat loss. They have feature of low density, high purity, low thermal conductivity, excellent thermal shock resistance. Types of Insulation Bricks: Cold Face Insulation Bricks Hot Face Insulation Bricks HFK Insulation Bricks Porosint Insulation Bricks Sizes: Standard 9 * 4.5 * 3 Inch
1. High temperature strength; 2. Resistant to corrosion in various atmospheres; 3. Excellent thermal shock stability; 4. Good thermal insulation; 5. The energy-saving effect is remarkable The operating temperature is below 1350C. Thermal insulation refractories are characterized by high porosity, generally 40%-85%; Low bulk density and low dry 1.5g/cm3: low thermal conductivity, generally less than 1.0W (m.K), it acts as the thermal insulation material of industrial kiln, can reduce the heat dissipation loss of the furnace, save energy, and can reduce the quality of the equipment under heat, the mechanical strength, wear resistance and slag erosion resistance of the thermal insulation refractory material is poor, and it is not suitable for the load-bearing structure of the kiln and direct contact with slag, charge, molten metal and other parts

We offer very high quality of Thermal Insulating Bricks, which are a perfect blend of porosity and brilliant insulating values. Besides this the Thermal Insulating Bricks we make, have a very high level of mechanical strength and low heat storage capability.
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.

It is produced by foam coagulation technique. Features: 1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance. 2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks. 3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained. Application: It is not only widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc, but also apply to linings in parts of furnace without strong high-temperature molten material erosive.
