Solid Fire Fe2O3 Clay Refractory Brick For Industry Furnace
Definition:
Soild Fire Clay Refractory Brick use Chamotte that the fire clay is calcinated as the main material. These bricks consist of fire clay and binder. The chemical components of these bricks are SiO2 and Al2O3. (Al2O3=25~40%) fireclay bricks are cheap so that they are used for all kinds of industrial furnaces.
The main applications of fire clay brick are the low temperature parts such as blast furnaces and hot blast furnaces, waste incinerators and glass melting furnaces. Due to the scale-up of a variety of industrial furnaces and severity of operating conditions, super dense fireclay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before.
Advantage:
1. High refractoriness,
2. High-temperature endurable.
3. Good corrosion resistance.
4. Good spalling resistance and wear resistance.
5. Good thermal shock resistance.
6. High mechanical strength.
7. High-temperature creep rate is low.
8. Good volume stability at high temperature.
Application:
Soild Fire Clay Refractory Brick can be used to furance contruction,blast furance/hot blast stove,steel foundries,furnace in the nonferrous metal industry,coke oven and gas furnace,galss industry,cement industry,safty lining of ladle and backup lining of boiler
