High Alumina Brick Introduce

High Alumina Brick is a kind of alumina-silicate refractory products with more than 48% content of Al2O3 inside, which are made of bauxite and other raw material.

High Alumina Brick Raw Materials

According to the different resource condition and products requirements, the following various raw materials can be adopted: High alumina bauxite which is mainly composed of hydrous aluminous minerals (diaspore and gibbsite). Sillimanite minerals (including kyanite, andalusite, sillimanite, etc.) Artificial synthetic raw materials, such as commercial alumina, synthetic mullite, fused corundum, etc.

Production Process of High Alumina Brick

The production process of high alumina brick is similar to the clay brick, the difference is that the clinker content is relative higher, can reach up to 90%~95%.

Properties of High Alumina Brick

High Alumina fire Brick  has various properties of high temperature strength, high thermal stability and good chemical slag erosion resistance, and is mainly used to build linings of Blast Furnace, Hot Air Furnace, Air Furnace, Reverberatory Furnace and Rotary kiln and etc.

Application of High Alumina Brick

High alumina fire bricks are mainly used in masonry in blast furnaces, hot blast heater, electric furnace roof, blast furnace, reverberatory furnace, lining of rotary kiln. In addition, high alumina refractory bricks are also widely used in open hearth regenerator, plug and nozzle brick of casting system.
