Description of Fire Clay Bricks
1. Fire clay bricks were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
2. Fire Clay Bricks is Al2O3 content of 30% to 35% aluminum silicate clay material products.
3. Refractoriness is 1580-1750°C, refractoriness under load is 1250-1450°C.
