Abstract
Official abstract text for this publication.
A carburizing device is configured to perform a carburizing treatment on a treatment target, and includes a furnace body, an insulating container provided inside the furnace body, a furnace bed provided inside the insulating container and on which the treatment target is mounted, and a heat source provided inside the insulating container, in which at least surfaces of main components of the furnace bed, the heat source and the insulating container are made of a ceramic material.
First claim
Opening claim text (preview).
What is claimed is: 1. A carburizing device configured to perform a carburizing treatment on a treatment target, the carburizing device comprising: a furnace body; an insulating container provided inside the furnace body; a furnace bed provided inside the insulating container and on which the treatment target is mounted; and a heat source provided inside the insulating container, wherein at least surfaces of main components of the furnace bed, the heat source and the insulating container are made of a ceramic material, wherein, as the main components, the furnace bed includes: a ceramic receiving member on which the treatment target is directly mounted; and a ceramic leg member that is provided to pass through the insulating container and includes a first end that is connected to the receiving member and a second end that is connected to the furnace body, and wherein the leg member is formed to be hollow and an inside of the leg member is filled with a fiber member made of a ceramic material. 2. The carburizing device according to claim 1 , wherein the leg member is connected to be detachable from the furnace body. 3. The carburizing device according to claim 1 , wherein the leg member faces the furnace body with an enclosed space therebetween. 4. The carburizing device according to claim 2 , wherein the leg member faces the furnace body with an enclosed space therebetween. 5. The carburizing device according to claim 1 , wherein the receiving member is connected to be detachable from the leg member. 6. The carburizing device according to claim 5 , wherein the receiving member and the leg member are connected to each other when a locking pin is inserted into both of a through-hole that is provided in the receiving member and a through-hole that is provided in the leg member.
