Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
It should be appreciated that ought use in this specification and in the appended claims, term " includes " and "comprising" instruction
Described feature, entirety, step, operation, the presence of element and/or component, but one or more of the other feature, whole is not precluded
Body, step, operation, the presence or addition of element, component and/or its set.
It will be further appreciated that the term "and/or" used in description of the invention and the appended claims is
Refer to any combination and all possible combinations of one or more of associated item listed, and including these combinations.
Fig. 1, Fig. 2 and Fig. 3, a kind of electromagnetic induction holding furnace are please referred to, holding furnace includes furnace body 11 and heat generating device；
Wherein, it is provided with furnace chamber among furnace body 11, molten metal can be held in furnace chamber；Heat generating device is arranged on the upside of furnace chamber, fever dress
It sets to support by column 16 and be arranged above furnace chamber, can also be arranged above furnace chamber by support frame across furnace chamber, this
Sample can reduce scattering and disappearing for heat generating device heat；Heat generating device includes induction coil 13 and heater 15, and induction coil 13 is set
It sets above heater 15；When there is molten metal to need to keep the temperature, molten metal is added from feed opening 17, is contained in furnace body 11
It in furnace chamber, when needing to keep the temperature, is powered to induction coil 13, under induction coil 13 is powered and generates alternating magnetic field, heater 15 is placed
Fang Shi, heater 15 are the electric current (being vortexed) for cutting alternate magnetic force line and generating alternation, and vortex makes heater 15 atom high speed
Random motion, atom collide with each other, rub and generate thermal energy.The heater 15 of fever is conducted heat by way of infra-red radiation again
To furnace chamber, molten metal is heated, heat preservation prevents its solidification, when needing using molten metal, takes out from material taking mouth 18；
This holding furnace does not need directly to be powered to heater 15, so heater 15 and molten metal would not be made to have energization to connect yet
The danger of touching, operator there will not be the hidden danger of electric shock, very easy to use, and heat generating device replacement is also very convenient, only
It need to be removed or be dismantled and is fixed.
Thermal insulation layer 14, the heat that thermal insulation layer 14 prevents heater 15 from generating are provided between induction coil 13 and heater 15
Amount is distributed into environment, and the most important heat that can be prevented from is collected at induction coil 13, causes 13 temperature mistake of induction coil
Height, resistance is excessive, so that electromagnetic induction heat efficiency substantially reduces, and is also possible to make since 13 temperature of induction coil is excessively high
The energization of induction coil 13 is obtained to burn out.For the heat insulation of thermal insulation layer 14, thermal insulation layer 14 is made of thermal insulation material, using silicate
Thermal insulation material or ceramic thermal insulation material, such good heat-insulation effect.
Outside induction coil 13, it is additionally provided with induction coil 13 casees 12, can protect operator, prevent its electric shock；
It is also prevented from other conductive materials simultaneously to contact with induction coil 13, causes its short circuit, cause the security risk of fire.
Heater 15 is graphitic carbon SiClx plate, and using graphitic carbon SiClx plate, heating efficiency is high, and long service life.
In order to guarantee the quality of furnace body 11, furnace body 11 is generally adopted as natural graphite, refractory clay or carbofrax material
Integrated molding is made, and guarantees its quality while reducing its processing program.
Induction coil 13 is generally spiral coil, can save space in this way, and heatable more efficient, induction coil
13 during the work time, and one side heater 15 can distribute heat to induction coil 13, on the other hand itself is powered and can also generate
Heat；Heat will affect the normal work of induction coil 13, it can be made to burn out when serious, melt, so some situations needs pair
Induction coil 13 cools down, and when induction coil 13 is arranged, induction coil 13 can be arranged to hollow pipe coil, centre is logical
Recirculated water or oil, heat is taken out of；In view of resistance and cost problem, induction coil 13 generally uses copper coil.
This programme is described in detail in embodiment, and specific case used herein is to structural principle of the invention
And embodiment is expounded, above embodiments are merely used to help understand method and its core concept of the invention；Meanwhile
For those of ordinary skill in the art, according to the thought of the present invention, has change in specific embodiments and applications
Become place, in conclusion the contents of this specification are not to be construed as limiting the invention.
