Abstract

PURPOSE:To attain good gas carburizing effect economically and safely by a method wherein nitrogen and an org. liquid agent are directly introduced into a carburizating furnace and, thereafter, a hydrocarbon type gas is added corresponding to a CO2 measuring value in an atmospheric gas in said furnace. CONSTITUTION:Nitrogen and an org. liquid agent such as methyl acetate or methanol are directly introduced into a carburizing furnace 1 from a supply pipe 2 to form a carrier gas. Thereafter, CO2 in an atmospheric gas in the furnace is measured by an infrared CO2 analyser 6 through a sampling pipe 5. Then, in a CO2 concn. controller 9, a CO2 set value corresponding to an equilibrium carbon concn. of the atmospheric gas set by a setting part 8 and the measured value are compared by a control part 10 and, corresponding to deviation thereof, a solenoid valve 4 of a hydrocarbon type gas supply pipe 3 is controlled. As described above, a predetermined equilibrium carbon concn. is held in the carburizing furnace 1 and gas cementation is applied to an article W to be treated.
