Title:
熱処理装置および熱処理方法
Document Type and Number:
Japanese Patent JP5517382
Kind Code:
B1
Abstract:
There is provided a method for heat treatment, a heat treatment apparatus, and a heat treatment system capable of performing highly precise and efficient control of heat treatment such as a bright treatment of materials to be treated with ease and safety. A heat treatment furnace has in-furnace structures made of graphite and has a heat-treatment chamber in which heat treatment of materials to be treated is performed. A value of G 0 (standard formation Gibbs energy) is computed with reference to the sensor information from respective sensors, and an Ellingham diagram, a control range, and a status of the heat treatment furnace in operation expressed by G 0 are displayed on a display device 331. A control unit 334 controls a flow rate of neutral gas or inactive gas as atmosphere gas or a flow velocity of the gas so that G 0 is within the control range.
