Embodiment 2
Electromagnetism curing system provided in this embodiment, the figure of first electromagnetic field inside sulfurizing mould therein is as schemed
Shown in 2, since hot-wire coil 3 is arranged in 7 outer circumference direction of steel plate, after acting on steel plate 7, electric field side
To be distributed along the circumferencial direction of steel plate 7, magnetic direction is perpendicular to the direction of 7 place plane of steel plate.It is schematically painted in figure
The distribution situation of the magnetic line of force and electric field line is made.First electromagnetic field effect is after on steel plate 7, at 3 position of hot-wire coil
Steel plate edge can be heated rapidly, and the width at the edge probably has 10mm or so.Since steel plate 7 is metal material, if its side
After edge is rapidly heated, by the heat transfer of metal, center can also be heated faster.
Preferably, the medium-high frequency power supply 300 further includes the second sub- power supply, and the second sub- power supply is inputted to the conducting wire

Rate and output current can determine the impedance for the hot-wire coil 3 being connect with the medium-high frequency power supply 300, because of the resistance of hot-wire coil
It is anti-related with the temperature field in space where it, so can conclude that hot-wire coil by way of determining hot-wire coil impedance in real time
Thermo parameters method situation inside corresponding middle mould can determine same layer steel plate not according to the thermo parameters method situation
Temperature conditions, the temperature conditions of different layers steel plate with position, thus can determine the second electromagnetic field and the first electromagnetic field it
Between phase difference how should adjust, also can determine how third electromagnetic field and the difference on the frequency of the first electromagnetic field should adjust.
That is, the medium-high frequency power supply 300 can determine the magnetic reactance of hot-wire coil, root according to output power and output current
The temperature field of steel plate is determined according to the magnetic reactance；According to the temperature field adjust second electromagnetic field and first electromagnetic field it
Between phase difference.Inside the processor of the medium-high frequency power supply, a temperature can be prestored and adjust threshold value, i.e. each layer of steel
Plate, temperature difference between steel plate edge and steel plate center (such as set no more than the adjusting threshold value and adjust threshold value and taken the photograph as 70
Family name's degree), when the temperature difference between steel plate edge and steel plate center is smaller, can control between the second electromagnetic field and the first electromagnetic field
Phase difference it is smaller, predominantly steel plate edge is heated.When steel plate edge and the temperature difference at steel plate center are Celsius close to 70
When spending, the phase difference of the second electromagnetic field and the first electromagnetic field is made to increase, main execution quickening heat is from steel plate edge into steel plate
The operation of heart transition.
In addition, the medium-high frequency power supply 300 determines the magnetic reactance of hot-wire coil according to output power and output current, according to institute
State the temperature field that magnetic reactance determines steel plate；It is adjusted between the third electromagnetic field and first electromagnetic field according to the temperature field
Difference on the frequency.That is, according to the distribution situation in temperature field, determines that the temperature of which layer steel plate is relatively low, then adjust at electromagnetic field peak value
Its temperature as early as possible with other layer of steel plate is set to reach to improve the heating speed to this layer of steel plate in this layer of steel plate position
