Product Description

Product Description

High alumina brick is a kind of alumina-silicate refractory material with content of alumina oxide more than 48%.usually made of high bauxite as the main raw material, through high temperature calcination. It has excellent fire resistance and high temperature resistance, and is often used in a variety of industrial furnaces, melting furnaces, glass kilns and other high temperature equipment lining and masonry. High aluminum refractory bricks usually have a high refractoriness and can withstand high temperatures of more than 1700 ºC, so they are widely used in industrial kiln.

Product Application

 

Applications:
I. Metallurgical Industry
Steel Industry: High-temperature blast furnace
Hot blast stove: As the inner lining of the combustion chamber and heat storage chamber
Reactor, electric arc furnace
Non-ferrous metal smelting
Smelting furnaces

II. Rotary kiln: Cement &lime Industry and so on

III. Chemical Industry
Fertilizer Industry & Coal chemical industry

IV. Power Industry
Boiler: The combustion chamber, superheater area of large power station boilers, and the high-temperature section of waste incineration boilers,
Superheater boiler: Used in the high-temperature heat recovery position, to improve the equipment's fire resistance and service life.

V. Other Industrial Fields
Ceramic industry: The high-temperature zone lining of ceramic kiln furnaces (such as tunnel kilns, roller kilns) withstand the high-temperature environment during the firing of ceramic bodies.
Waste treatment: The furnace lining of waste incinerators, to resist the high temperature and complex corrosive gases (such as HCl, SO2, etc.) generated by waste incineration erosion.
