ABSTRACT:
A method and apparatus for the continuous preheating of charge materials for an electric steelmaking furnace operation including provision for preheating with both off-gas from the furnace and burners in the preheating chamber. Seals are provided to prevent uncontrolled escape of gases from the chamber, and cooling air is also heated for use elsewhere. The invention contributes to the process of continuous steelmaking, including charging and tapping while maintaining full electric power, and having good control over both quality and product chemistry.
