  • Method for maintaining a temperature of a metal melt
    Patent number: 9500528
    Abstract: A temperature of a metal melt in a furnace is maintained after blowing away slag from a surface of the metal melt by the flow of oxygen and switching over from oxygen to an inert gas, such as nitrogen. A measured temperature of the metal melt is accepted as a metal melt temperature only when the inert gas flow is in a laminar state and after the measured temperature has fluctuated by a maximum of 1% over a period of at least 2 seconds.

  • METHOD AND DEVICE FOR DETERMINING A TEMPERATURE T OF A METAL MELT WITHOUT CONTACT
    Publication number: 20120140787
    Abstract: A temperature T of a metal melt in a furnace is precisely determined without contact using at least one burner gun unit fed through a furnace wall of the furnace above the metal melt into a furnace chamber and at least one temperature measuring unit downstream of the burner gun unit.
