Product Description

High aluminum insulation/Refractory brick for high temperature insulation working layer/Good insulation performance

 

Product description:
Light and tall aluminium brick is to point to contain AL2O3 45% above commonly all sorts of light and refractory.It is usually divided into two categories: one is ordinary lightweight high-alumina brick made from natural high-alumina clinker;The other is high quality light weight and high alumina products made from electrofused or sintered alumina, because its main crystal phase is corundum, also known as light corundum brick.Lightweight high alumina brick is generally produced by the foam method, and the clinker is grinded and mixed with the binder and foaming agent to prepare the mud and then poured into shape.The service temperature of light high-alumina brick is 1350℃-1500℃, and the service temperature of high-purity products is 1650℃-1800℃.
Features:

Its high fireproof and good thermal shock resistance, it is mainly used in the high-temperature insulation layer of kiln and the lining of furnace which is not easy to be directly touched by slag erosion flame.
