High Aluminium Refractory Bricks

 

1. Product description

Alumina bricks are made from bauxite of super quality, bonding chamotte and additives. The main Al203 content is 48%-99%. The advantages of high alumina bricks are high refractoriness, anti alkaline/acid erosions, good strength under high temperature and good thermal shock resistance. High alumina bricks were widely accepted in thermal equipment of metallurgy, petroleum, chemical industry, construction materials, machinery and militaries etc.

 

2. Features

1. Low bulk density, low thermal conductivity, good thermal insulation performance.

2. Refractory category allow direct contact of fire, suitable ofr various atmosphere

3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

4. Product specification: standard form, normal standard, shaped and special shaped bricks.

5. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory   materials, it is the most widely used.

 

3. Applications

1. Furnaces of metallurgy industry, heat treatment furnace

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace

 

4. Physical and chemical index
