Abstract
There are provided a method for heat treatment, a heat treatment apparatus, and a heat treatment system capable of efficiently controlling heat treatment such as a bright treatment with high precision and without causing oxidation and decarbonization. Computation of ΔG(standard formation Gibbs energy) is performed by referring to sensor information from respective sensors, and an Ellingham diagram, a control range, and a status of the heat treatment furnace in operation expressed with ΔGare displayed on a display device, while a flow rate of hydrocarbon gas is controlled by a control unitso that ΔGis within the control range.
