For applications such as Ferro-silicon, industrial Silicon and Carbide, we recommend our insulation concept lining structure . In this structure, the working layer carbon materials,
1. The semi-graphite blocks have proven to have good erosion resistance and good overall structure strength.
2. The high-alumina bricks in the permanent layer are oxidation-resistant and erosion resistant.
3.Products such as Carbide, Ferro-silicon, have higher melting point. The insulation layer reduces the thermal loss, increases the temperature of the molten metal and reduces the workload on the exhaust system.
4. Overall this structure is able to provide higher temperature in the furnace working area and also prevent furnace bottom infiltration.
THE SPEC OF CARBON BRICK :
1 C > 90 ; Ash < 8, BD> 1.65 G/CN3
2 C > 55 ; SIC > 33 ; BD : 1.8G / CM3
