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.
