Title: Heat treatment of steel products
Inventor: MARUKAWA KUNIHIKO
IPC: C21D1/76
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To avert the decarburization of steel products in a heat treatment without removing the scale of the steel products by increasing the CO concentration of an atmosphere prior to final heating, then once lowering the CO concentration and execution heating and atmosphere control. SOLUTION: The atmosphere control prior to the final heating preferably increases a (CO)2/CO2 ratio (CP value) in the intra-furnace atmosphere in a range of 20 to 200. After the CO concentration of the atmosphere is increased at the time of low temperature prior to the final heating, the CO concentration is once lowered and more particularly the CP value is decreased to <20, more preferably down to zero, and thereafter, the final heating is executed. Above all, the replacement of the intra-furnace atmosphere by supplying gaseous nitrogen, or the like, into the furnace in order to decrease the CP value once to zero results in the complete expulsion of the gaseous CO2 formed in the furnace. Then, there is an advantage in that the smaller amount of a gaseous RX to be fed is necessitated at the time of control of the CP value by introducing the gaseous RX again.
