Embodiment Construction

[0022] Figure 1 shows a 6KW microwave heating system consisting of a microwave heating furnace and a controller.

[0023] Figure 2 shows a box for heat treatment in a 6KW microwave oven consisting of blocks of alumina wrapped in a low density fibrous material.

[0024] Figure 3 shows a 150 x 30 x 15 mm specimen heat treated in a microwave oven and then cooled in air. Five to six of these samples can be placed together in the furnace at one time for uniform heat treatment.

Description

technical field [0001] The invention relates to a method for heat-treating metal samples by using microwaves. [0002] The invention also relates to a method for rapidly and uniformly heat-treating large metal samples by using microwaves. Background technique [0003] As one of the most critical stages in the heat treatment of metals, heating must be precisely controlled to obtain the desired properties and avoid property changes that would lead to failure during service. [0004] Microwave heating uses microwaves to heat large metal parts. Microwave heating is a very fast and efficient process compared to conventional processes for heating metal parts. Microwave heating can be successfully used on a range of materials, including metals such as various steels and alloys of copper and aluminum. Advantages of this process include: significantly faster heating rates, uniform mechanical properties, energy savings, immediate and good control over temperature and process. Howe...
