HEAT TREATMENT OF FERROUS METALS IN CONTROLLED GAS ATMOSPHERES ABSTRACT An oxygen bearing medium comprising oxygen and or a compound constituting oxygen, is mixed in combination with at least one of hydrogen and carbon, a hydrocarbon and a gaseous inert carrier forming the major component (by volume) of the mixture. The mixture is heated to bring about chemical interaction of the components to produce a carbon controlled atmosphere. For safety, the chemical interaction occurs preferably within the furnace itself whereas with conventional generators the gas atmosphere is piped to the furnace.
