Problems solved by technology

[0009] However, these resistance heating element materials are expensive as materials and inferior in workability as compared with heat-resistant steels currently used as jigs for heat treatment.
Therefore, in the above-mentioned conventional invention, there is a problem that the cost of the jig for heat treatment is higher than that of the conventional jig for heat treatment.

Embodiment Construction

[0055] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0056] In addition, the first to fourth embodiments described below are characterized in that they all have heat treatment jigs for holding the object to be processed in the heat treatment apparatus, and that the heat treatment apparatus has substantially the same configuration. Therefore, before describing the first to fourth embodiments, refer to figure 1 The overall structure of the heat treatment apparatus will be described.

[0057] The main body container 1 of this heat treatment apparatus is formed in a substantially hollow circular tower shape, and is installed on the floor in a lying state. One end of such a main body container 1 is provided with an opening and closing door (not shown) for allowing the object X held by the heat treatment jig Y (tray type heat treatment jig) to enter and exit. In ad...

Abstract

It is possible to increase a selection range for selecting a material of a thermal treatment jig (especially, a material of a resistance heating element) so as to suppress cost increase of the thermal treatment jig, make heater output uniform, and improve thermal efficiency. For subjecting a treatment object to a thermal treatment, a thermal treatment jig is for holding a treatment object and resistance-heating the treatment object by external power supply. The terminal treatment jig is formed by a base material mixed with a resistance heating material having a higher specific resistance than the base material.

Description

technical field [0001] The present invention relates to a jig for heat treatment holding an object to be processed, and a heat treatment apparatus and method for heat treating the object held by the jig for heat treatment. Background technique [0002] For example, Japanese Unexamined Patent Application Publication No. 2004-315917 discloses an inventive technique in which a plurality of heaters are used to heat an object to be processed held by a heat treatment jig, and at the same time, the resistance of the heat treatment jig is heated by energization, thereby reducing the temperature of the heat treatment jig. The object to be treated is subjected to heat treatment. [0003] That is to say, in the present invention, when a plurality of heaters arranged in the heat treatment furnace are used to uniformly heat the object to be treated held by the heat treatment jig, the heat treatment jig and the furnace arranged below the heat treatment jig The output of each heater cause...
