Advances in alumina carbon refractories

Introduction of continuous casting has imposed much tougher working conditions such as higher tapping temperature, and longer holding time. This demands superior refractories in iron and steel making processes. Al2O3-C brick is characterised by its excellent resistance towards slag corrosion, thermal and structural spalling and has got good residual expansion at higher temperature. The development and application of alumina-carbon refractories at the metal zone and bottom of steel teeming ladle and ladle furnaces has proved its superiority over conventional refractories.
