Abstract
Official abstract text for this publication.
A heat treatment system includes heating chambers configured to perform heat treatment on objects to be treated, and a conveyance device configured to load each of the objects to be treated into the heating chambers, unload the object to be treated from the heating chambers, and convey the object to be treated under an oxygen-free atmosphere, wherein the conveyance device includes a cooling device configured to perform cooling treatment on the object to be treated.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat treatment system comprising: a plurality of heating chambers arranged in a row and configured to perform heat treatment on an object to be treated; a conveying rail provided along the plurality of heating chambers; a conveyance device configured to load the object to be treated into the plurality of heating chambers, unload the object to be treated from the plurality of heating chambers, and convey the object to be treated under an oxygen-free atmosphere, while moving on the conveying rail; and a delivery device that is provided such that the delivery device is disposed on one side of two sides of the conveying rail and the plurality of heating chambers are disposed on the other side of the two sides of the conveying rail, and delivers and receives the object to be treated to and from the conveyance device, wherein the conveyance device includes a cooling device configured to perform cooling treatment on the object to be treated. 2. The heat treatment system according to claim 1 , wherein the cooling device includes an oil cooling device configured to cool the object to be treated using a predetermined cooling oil, and a gas cooling device configured to cool the object to be treated using a predetermined cooling gas.
