Abstract
An apparatus (16) for heat treating manufactured components (24) using microwave energy and microwave susceptor material (20). Heat treating medium (22) such as eutectic salts may be employed. A fluidized bed introduces process gases (118) which may include carburizing or nitriding gases. The process may be operated in a batch mode or continuous process mode. A microwave heating probe (80) may be used to restart a frozen eutectic salt bath.
Claims
AMENDED CLAIMS
[received by the International Bureau on 21 March 2007 (21.03.07); original claims 9-10 amended; original claim 23 cancelled; remaining claims unchanged]
7. The system of Claim 6 wherein the microwave susceptor material comprises a layer of microwave susceptor material bonded to the exterior surface of the corrosion-resistant heat treating vessel.
8. The system of Claim 7 wherein the microwave susceptor material comprises fluid microwave susceptor material filling a substantial portion of the space between the casket and the heat treating vessel, so that a substantial portion of the exterior surface of the heat treating vessel is in contact with the fluid microwave susceptor material.'
9. A method of heat treating a metal component, the method comprising: melting a salt using microwaves; placing the metal component in the molten salt; heating the molten salt sufficiently to maintain the molten state; and removing the metal component from the molten salt.
10. The method of Claim 9 wherein the step of heating the molten salt sufficiently to maintain the molten state comprises heating the molten salt using microwave energy.
11. 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 moderating material selected from the group consisting of
(a) microwave susceptor materials and
(b) a mixture of microwave susceptor material and 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.
27
19. A method of heat treating components, the method comprising: loading a fluidized bed insulating vessel with components and granular microwave susceptor material such that a substantial portion of the exterior surface of each component is in contact with the granular microwave susceptor material; exposing the loaded fluidized bed insulating vessel to microwave radiation; and pumping process gas into the loaded fluidized bed insulating vessel.
20. The method of Claim 19 further comprising pumping surface treatment gas into the loaded fluidized bed insulating vessel.
21. The method of Claim 20 further comprising pumping carburizing gas into the loaded fluidized bed insulating vessel.
22. The method of claim 20 further comprising pumping nϊtriding gas into the loaded fluidized bed insulating vessel.
23. (cancelled)
24. An apparatus for heating a reactant disposed in a material processing vessel, the apparatus comprising: a probe incorporating microwave susceptor material;
