High Alumina Insulation Brick Product description
Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulating heat. Light weight high alumina bricks contain more than 48% alumina oxide. This kind of brick does not directly exposed to high temperature inside kilns or furnaces, it only built closely to the kiln wall as insulations. It is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.
High temperature endurable high alumina refractory brick/tile for tunnel kiln is made by clay clinker or light clinker and plastic clay as the main raw material, usually fuel production, but also can send or chemical foaming method porous structure. Common light chamotte bulk density of 0.75 ~ 1.2g / cm3. It refers to containing AL2O3 30% ~ 46% of lightweight refractory products, mainly for industrial kilns does not melt and no erosion of the contact action of gas insulation layer material, the using temperature is 1200 ~ 1400 ° C.
High Alumina Insulation Brick Specifications
1. According the shape, it can be divided into standard brick, special-shaped brick.
2. According thecharacteristic, it can be divided into high alumina insulating brick, fire clay insulating brick, Mullite insulating brick, corundum insulating brick, etc.
3. According the application, it can be divided into building materials for blast furnace, Building materials for coke oven, Building materials for steel making furnace and so on
High Alumina Insulation Brick Features
1.Excellent strength at ambient and elevated temperatures.
2.High compressive strength.
3.Very low levels of iron and other impurities.
4.Lightweight and energy-efficient.
5.Lower heat storage than denser refractory.
6.Heats quickly and economically to operating temperature.
