Product Description
High Aluminum Refractory Fireclay Bricks

High alumina brick refers to fire brick containing Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. High alumina brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractoriness under load, which decide high alumina brick is a n ideal material for various kinds of industrial furnace. It is widely used in building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
 
The content of Al can be controled according to your tech data.
We have a professional team to make sure the quality.
We also provide free example for testing!

Modern large, medium-sized blast furnace, requires 10 years (or 15 years) service life for a furnace generation, which translates into strict requirements on types and quality of refractories. Refractory varies from locations inside blast furnace due to huge temperature fluctuations and different reaction conditions in different locations with thermal shock to suffer, Different parts of the blast furnace: high alumina.
