  • Process for treating metals using recycled gases
    Patent number: 4219324
    Abstract: A process is described for treating metals in a furnace by indirect heating techniques, e.g., by using a radiant tube heater, wherein the gas used for heating is passed out of the furnace, treated in a known manner, and passed back into the furnace to serve as the source for the treating atmosphere or as a carrier gas. Carburization of metals can be carried out by this method which results in a savings in fuel and overall operational expense.
