Fireplace Fire Clay Brick High Density , Insulation Refractory Brick
The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.
Description:
The low Porosity clay refractory bricks are made of super calcined flint clay and calcined bauxite, With high Pressure formed and high temperature sintered. Due to its low apparent porosity, Strong resistance to erosion and high refractoriness under load, They are wildly used in Glass kiln, Blast furnace, Metal mixer Furnace, Hot metal mixer ladle, Coke dry quenching devices , etc.
Laurel Fire clay bricks are made of local top-grade chamotte under the high pressure pressed, then sintered in high-temperature tunnel kilns. I has the features of high bulk density, excellent crushing strength and low apparent porosity. Fire clay bricks are widely used in all parts of furnace lining, blast furnaces and thermal equipment because of their superior physical and chemical properties in high temperatures. It also has good thermal shock stability and erosion resistance to acidic slag.
Features:
1. Low porosity,High bulk density.
2. Good Cold Crushing strength.
3. High refractoriness under load.
4. High mechanical strength.
5. Good resistance to erosion.
Applications:
1. Glass kiln
2. Blast furnace
3. Metal mixer Furnace,
4. Hot metal mixer ladle
5. Blast furnaces
