Abstract

PURPOSE:To provide a titled heat treating furnace which is simple in construction, has good efficiency and heats uniformly and quickly the entire part of the furnace body by constituting in such a manner that the outside circumference of a furnace body consisting of a heat resistant dielectric material is enclosed with a heat insulating material having a low loss of electromagnetic wave and an outside frame formed of metal, and the electromagnetic wave is irradiated to such furnace body. CONSTITUTION:The outside circumference of a furnace body 1 consisting of a heat resistant dielectric material such as SiC sintered body or the like is enclosed with an outside frame 3 formed of metal via a heat resistant heat insulating material 2 having a low loss of microwave and the top end of a microwave guide 4 is connected in the aperture 3a of the frame 3. A material M to be heated is charged into such body 1 and the microwave W is conducted through the waveguide 4 to irradiate the microwave W at a low loss through the material 2 to the body 1, thereby heating dielectrically the body 1 and increasing quickly the temp. thereof. The material to be heated is subjected to a heating treatment by the radiation heat and conduction heat from the body 1. The material to be heated may be either metal or non-metal and the electromagnetic wave of about >=100kHz is used as the electromagnetic wave to be irradiated.

線、その他の故障が生じ易い等の問題点がある。Conventional electric furnaces for heat treatment include resistance furnaces, arc furnaces,
There are four induction electric furnaces, but none of them are capable of rapidly and uniformly heating the entire furnace, and because the furnace body itself is not a heating element, the power density is low and efficiency is low. Further, there are problems such as the efficiency of energy conversion into heat is poor, and the structure of the device is complicated, making it easy for disconnection with the heating element and other failures to occur.

。Next, the action will be explained. When microwaves are guided from a microwave oscillation source through the waveguide 4, the microwaves induce the heat insulating material 2 with low loss and are irradiated to the furnace body 1. The furnace body 1, which is a dielectric material, is heated by Ilf+ radiation of microwaves and rapidly rises in temperature. The workpiece M is heat-treated by the @law heat or conduction heat from the furnace body 1. In this case, since the object to be processed M is not heated by irradiating the W-contact microwave, the object to be processed may be a non-inductive material such as gold.Microwave W is gold fx% QJ
It is contained within the furnace by the outer frame 3 and does not leak to the outside.

良いという効果が得られる。As explained above, the present invention has a configuration in which the furnace body 1 made of a heat-resistant dielectric is electrically heated by irradiating microwaves, and the object to be heated inside is heated by the radiant heat and conductive heat. Therefore, the entire furnace body 1 can be heated uniformly and rapidly, and compared to furnaces that use resistance heating, degenerate heating, or discharge heating, it is easier to warn, there are fewer failures, and it is more efficient. Effects can be obtained.
