1770<Refractoriness<2000 High temperature fireproof dense high alumina refractory brick for furnace/kiln
Product Description
1.Description
High alumina refractory brick contain Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. Its refractories is usually above 1770 °C. The main mineral components are corundum and mullite phases. It is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. According to Al2O3 content,it can be divided into three degrees:The Al2O3 content is more than 75%.The Al2O3 content range from 60% to 75%.The Al2O3 content range from 48% to 60%.
2.Feature
1. High-temperature endurable .
2.Good thermal shock resistance.
3.High cold crushing strength
4.Good resistance to abrasion and corrosion.
5.Good thermal spalling resistance.
6.High mechanical strength.
7.Good volume stability at high temperature.
