Lightweight High Aluminum Insulating Refractory Brick Factory For Insulation Lining
Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing
High temperature endurable high alumina refractory brick/tile for tunnel kiln in Vietnam 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.

Light weigt bricks feactures:
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 of light weight bricks:
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.
Details:
1. Made by flint clay clinker and binder,through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2. Al2O3 content is 30%-48%,SiO2 content is 50%-65%,and a small number of alkali metals,alkaline earthmetal oxides TiO2,Fe2O3 etc.3.Working temperature:less than 1350°C.
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.
