Design for blast furnace & hot blast stove

High alumina bricks for blast furnace: the main component is mullite and corundum phases, with excellent high temperature physical properties and chemical corrosion resistance, anti-spalling/acid erosions, good strength under high temperature and good thermal shock resistance, high spalling resistance;

Applications: widely used in every part of blast furnace lining with good work ability.

 

Fire clay bricks for blast furnace: fire clay bricks are made from excellent kaolinite being high pressure pressed and sintered in high temperature. Main mineral compositions are mullite phases. These products were widely used in all parts of furnace lining for middle and small capacity blast furnace because of their excellent physical and chemical properties in high temperature.

Characteristic: low bulk density, low thermal conductivity, good thermal shock resistance. Refractory category allows direct contact of fire, suitable for various atmospheres.

 

Al-C bricks: Aluminum carbon bricks for blast furnace:

Aluminum carbon bricks have many good unique performances, mainly used in iron and slag outlet and belly tray and bottom liner. The aluminum carbon fire bricks are made of the bauxite grog, corundum and purity graphite, adopted the advanced technology to improve their performances. They have the advantages of high heat transmission and anti-slag eroding, etc. they are suitable for areas of iron, slag outlet and belly tray and bottom liner of large and medium blast furnace.
