Abstract
Official abstract text for this publication.
A heat treatment facility performing a heat treatment on a workpiece, the heat treatment facility includes: a treatment container in which the workpiece is housed; a heater which is provided in the treatment container and heats the workpiece by radiation heat at least from below the workpiece; and a plurality of support posts which are provided in the treatment container and support the workpiece.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heat treatment facility performing a heat treatment on a workpiece, the heat treatment facility comprising: a treatment container in which the workpiece is housed; a heater which is provided in the treatment container and heats the workpiece by radiation heat at least from below the workpiece; and a plurality of support posts which are provided in the treatment container and support the workpiece, wherein a pillar part of at least one support post of the support posts includes a narrow part at a portion facing a heating element of the heater such that the narrow part and the heating element overlap so that an imaginary line perpendicular to an axial direction of the pillar part passes through both the narrow part and the heating element, and the narrow part is a portion of the pillar part that is between a lower end of the pillar part and an upper end of the pillar part and that includes a cross-sectional area that is smaller than that of an outer peripheral shape of all other portions of the pillar part outside of the narrow part. 2. The heat treatment facility according to claim 1 , wherein a portion, which comes into contact with a mount to be mounted on the support post, of the support post is formed of ceramics. 3. The heat treatment facility according to claim 1 , wherein the support post is configured to come into line contact with a mount to be mounted on the support post. 4. The heat treatment facility according to claim 1 , wherein the support post is configured to allow a contact structure coming into contact with a mount to be mounted on the support post to be attachable thereto and detachable therefrom. 5. The heat treatment facility according to claim 1 , wherein the support post comprises a base and the pillar part detachably attached to the base.
