Description
Technical field
The present invention relates to electromagnetism smelting furnace technical field, and in particular to a kind of double-zone heat electromagnetism melting and heat preservation smelting furnace.
Background technology
Existing electromagnetic induction smelting furnace is typically all Medium frequency induction smelting furnace, by electromagnetic power source, induction coil, cooling system group
Into.Electromagnetic power source is the medium frequency alternating current that power frequency 50Hz alternating current is become to 5-15KHz by IGBT, and this intermediate frequency is electrically added
Transformer is exported, that is, generates the magnetic field of a respective frequencies, crucible produces vortex under the influence of a magnetic field, crucible itself is sent out
Heat.Current existing electromagnetism smelting furnace is all to take output transformer to carry out impedance matching, extremely inefficient.Its induction coil only has one
Group, is overall heating during heating.When aluminium liquid only has half crucible, part will also keep heated condition on crucible, cause unnecessary
Energy waste.Oxidation is serious during crucible empty heating simultaneously, shortens the service life of crucible.
The content of the invention
The present invention is directed to existing electromagnetic induction smelting furnace above shortcomings, it is desirable to provide a kind of double-zone heat electromagnetism insulation
Smelting furnace.
Technical scheme is as follows.
A kind of double-zone heat electromagnetism is incubated smelting furnace, includes body of heater, temperature detector and controller, is characterized in that：Body of heater
Include crucible, the muff outside crucible and muff Wai Shang area's induction coils and lower area induction coil；The top of crucible
It is further fixed on liquid level sensor；Temperature detector includes positioned at crucible Wai Shang area's temperature detectors and lower area temperature detector；Controller is distinguished
It is connected upper and lower to receive the liquid level information and sidewall of crucible of crucible inner metal liquid with liquid level sensor and upper and lower area's temperature detector control line
The temperature information in area, controller controls the work of upper and lower area's induction coil according to the level value of setting, when liquid level sensor is visited
When the crucible inner metal liquid liquid level measured is higher than set level value, controller drives upper and lower area's induction coil to work simultaneously, when
When the crucible inner metal liquid liquid level that liquid level sensor is detected is not higher than set level value, controller only drives lower area's line of induction
Enclose work.
Controller uses full-bridge series resonance circuit, eliminates the output transformer or direct current reactor of intermediate frequency furnace, uses
IGBT replaces GTO, makes performance stabilization efficiency higher.
Preferably, controller can also connect man-machine interaction unit so as to controller input level value or observation temperature,
The data such as liquid level.
Preferably, infrared level sensors may be selected in liquid level sensor.
The beneficial effects of the present invention are：Compared with existing Medium frequency induction smelting furnace, technical solution of the present invention is by using double
Area is controlled, can according in crucible material number, export appropriate power, reduce energy waste；And when metal in crucible
When liquid liquid level is less than setting value, can control area on crucible and stop heating, it is to avoid because sky heating in area's on crucible and caused by aoxidize it is serious
Situation, be effectively improved the service life of crucible.Controller uses full-bridge series resonance working method, direct using IGBT
Induction coil is driven, output transformer or direct current reactor is removed, makes system more stable, it is more efficient.
Brief description of the drawings
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the control system figure of the present invention.
In figure：1 infrared level sensors, 2 crucibles, 3 muffs, area's induction coil on 4,5 times area's induction coils, on 6 area
Temperature detector, 7 times area's temperature detectors, 8 two-region controllers.
Embodiment
Below with reference to specific embodiment, the present invention is described in detail.
Embodiment 1
As shown in accompanying drawing 1,2, the embodiment includes body of heater, temperature detector and controller, and body of heater includes crucible 2, outside crucible
Muff 3 and the muff Wai Shang areas line of induction 4 and the lower area line of induction 5；Infrared level sensing is further fixed on above crucible
Device 1；Temperature detector includes positioned at crucible Wai Shang areas temperature detector 6 and lower area temperature detector 7；Controller is sensed with infrared level respectively
Device and the connection of upper and lower area's temperature detector control line are believed with the temperature for receiving the upper and lower area of liquid level information and sidewall of crucible of crucible inner metal liquid
Breath, controller is also associated with man-machine interaction unit and inputs level set value with data such as displays temperature, liquid levels or to controller（Example
Such as expire the 50% of liquid level）, controller controls the work of upper and lower area's line of induction according to the level value of setting, when liquid level sensor is visited
When the molten metal liquid level measured is higher than set level value, controller drives upper and lower area's line of induction to work simultaneously, works as level sensing
When the molten metal liquid level that device is detected is not higher than set level value, controller only drives lower area's line of induction to work；Controller is adopted
Full-bridge series resonance circuit is used, the output transformer or direct current reactor of intermediate frequency furnace is eliminated, replaces GTO with IGBT, make performance
Stabilization efficiency is higher.
The principle of heating of the embodiment is controller control two-way identical driving and IGBT, and output is then directly connected to sensing
Coil-end.During work, liquid level and temperature signal outside controller collection, it is determined that output is single channel or two-way.Middle control is produced
High-frequency signal by drive amplification drive IGBT, the thing formed in induction coil in corresponding high frequency magnetic field, crucible and crucible
Material produces vortex under the influence of a magnetic field, makes crucible and material fast heating, reaches material after certain temperature and starts to dissolve.
When the aluminium liquid in crucible is in a high position, two-way induction coil is to work simultaneously, is that crucible is integrally heated.With aluminium liquid
Use, liquid level is gradually reduced, if at this moment continuing to heat upper area, necessarily cause unnecessary energy waste and the longevity is used to crucible
The influence of life, therefore we set a liquid level height value, when molten metal liquid level is reduced to this setting height, upper area stops
Heating, lower area works on.Two temperature sensors detect temperature of aluminum liquid in real time（Crucible wall temperature）, realize thermostatic control.
