Blast furnace tuyere bricks

For tuyere bricks, high alumina bricks, which show excellent resistance against thermal spalling and molten iron attack, have been applied for years. On the other hand, non-oxide materials like silicon carbide bricks, which are excellent in corrosion resistance against alkaline and slag, have recently been very popular, as they can prevent abnormal bloating, tuyere deformation, or slag adhesion due to alkaline penetration into the brick structure.
