Surface Combustion, Inc. Awarded US Patent
Surface Treatment of Metallic Articles in an Atmospheric Furnace (US 8,293,167 B2)
October 23, 2012
Surface Combustion, Inc. was awarded a patent for the inventions of delivery of atomized liquid hydrocarbons to yield a reactive atmosphere inside an industrial heat treat furnace. The atmosphere may be comprised of any variety of hydrocarbons to create a carburizing, reducing, or reactive atmosphere for materials processing. The patent also covers the application to an atmosphere generator (carrier gas) as well as acting as an enriching gas to increase carburizing potential.
The delivery of hydrocarbons is metered and can be introduced in finite, pulsed-dosages to allow process control.
The invention can be applied to Allcase® Batch Integral Quench Carburizing furnaces, RX® Endothermic Gas Generators, or continuous carburizers. Additionally, RX® endothermic gas recycling can be aided with the invention.
The inventors include Ralph Poor, John Gottschalk, and William Bernard Jr.
