Heat treating of manufactured components
View Patent ↗An apparatus for heat treating manufactured components using microwave energy and microwave susceptor material is disclosed. The system typically includes an insulating vessel placed within a microwave applicator chamber. A moderating material is positioned inside the insulating vessel so that a substantial portion of the exterior surface of each component for heat treating is in contact with the moderating material.
1. A heat treating system, the system comprising an insulating vessel placed within a microwave applicator chamber, the insulating vessel being thermally insulating and substantially transparent to microwave energy, wherein the insulating vessel holds at least one component for heat treating, each component having an exterior surface, and wherein the insulating vessel further holds a moderating material selected from the group consisting of
(a) a granular microwave susceptor material, and
(b) a mixture of a granular microwave susceptor material and a microwave transparent material,
where the moderating material is positioned inside the insulating vessel so that a substantial portion of the exterior surface of each component for heat treating is in contact with the moderating material.
2. The heat treating system of claim 1 wherein the moderating material consists of the microwave susceptor material.
3. The heat treating system of claim 1 wherein the moderating material consists of the mixture of the microwave susceptor material and the microwave transparent material.
4. The heat treating system of claim 1 wherein substantially all of the exterior surface of each component being heat treated is in contact with the moderating material.
