Abstract (en)
[origin: EP0063655A1] A process for carburizing steel in a furnace, using an atmosphere derived initially from decomposition of an oxygenated hydrocarbon containing up to three carbon atoms having a carbon to oxygen ratio of from 1 to 2 such as alcohols, aldehydes, ethers, esters and mixtures thereof injected into the furnace until the initial rapid stage of carburization is completed; then blending nitrogen into the oxygenated hydrocarbon atmosphere throughout the remainder of the process so as to minimize energy usage; and continually adjusting the carbon potential by addition of a hydrocarbon enriching or carburizing agent to maintain carbon potential of the furnace atmosphere within the desired limits during the entire carburizing cycle.
