  • Preheaters for preheating steelmaking ladles
    Patent number: 8585961
    Abstract: Embodiments of the invention comprise a preheater for preheating a ladle for use in steelmaking wherein less fuel is consumed in heating the ladle efficiently and accurately to a controlled temperature. A preheater temperature is varied by controlling a burner of the heating unit based on measurements of refractories of the ladle taken by a pyrometer. The heating unit of the preheater includes an emissive coating for reducing heat loss and efficient heating during the preheating process. The heating unit of the preheater also includes valve mechanisms for accurately varying a flame size of the burner by regulating the rate of fuel, air, and oxygen supplied to the heating unit.
    Type: Grant

  • Method of preheating steelmaking ladles
    Patent number: 8142541
    Abstract: A method for when preheating a ladle for use in steelmaking where less fuel is consumed in heating the ladle efficiently accurately to a controlled temperature. A temperature of a preheating process is varied by controlling a burner of the heating unit based on measurements of refractories of the ladle taken by a pyrometer. The heating unit includes an emissive coating for reducing heat loss and efficient heating during the preheating process. The heating unit also includes valve mechanisms for accurately varying a flame size of the burner of the heating unit during an idle stage of the preheating process.
