Intermediate frequency induction heating equipment, the principle of induction heating machine: is the use of the high frequency of large current flows are around to make the desired shape of the ring or heating induction coil, high frequency induction
is usually made into hollow copper controls.
Produced by high-frequency induction coil in instantaneous changes of strong magnetic polarity beam, will need to heat treatment of metal is placed within the high frequency coil, a magnetic beam will be well versed in the heated metal objects.
In the interior of the induction heating object with induction heating current in the opposite direction, should produce relatively strong eddy current.
Because of induction heating metal resistance exists inside, so the stronger effects of joule heat, make the induction heating object temperature rising rapidly, so as to achieve the purpose of heat treatment.
Using power MOSFET and IGBT devices and frequency conversion control technology, high efficiency, energy saving, the output power is bigger;
With constant current and constant power control function, greatly optimize metal heating process, implement efficient and rapid heating, get a great play product superiority;
Under the same condition is better than traditional tube high frequency heating equipment to save electricity double effect;
With 100% load design, can work 24 hours a day in a row, can match the infrared measuring temperature to realize the automatic control of temperature, improve the quality of heating, simplifying the manual operation;
Cooling three time setting function, can obtain the required heat insulation process, to adapt to the place of heat and mass, repeatability;
Have over-current, over-voltage, owe water, lack of phase, load unwell wait for a variety of status display, provide higher reliability and durability;
According to the power and frequency selective power, the higher the frequency heating depth is shallow, the lower the frequency diathermy, the better;
Technology - induction heating equipment
Application of annealing and tempering & emsp;
Annealing the workpiece of heating to proper temperature, according to the material and workpiece size in different heat preservation time, and then slow cooling (
Cooling speed of the slowest)
, the purpose is to make the metal internal organization at or near equilibrium state and obtain good process performance and use of performance, or for further quenching organization.
Using induction heating instead of gas or heating furnace for preheating has many advantages.
Heat conduction can directly, this will minimize heat loss and energy loss, increase production efficiency, improve product quality.
At the same time, the heat can be precisely controlled, so that can reduce the temperature when welding, so as to reduce the cooling speed.
In addition, there is conducive to reduce the risk of cold crack and hardening, the use of induction heating, you don't have to face the heat of the flame, so as to improve the working environment, reduce the demand for the cooling system, reduce the fire danger.
Using conditions & emsp;
The environment temperature in 3 -
Within the scope of 40 ℃.
0 ℃ antifreezing measures should be taken to the following area)
Using area biggest monthly average no greater than 90% relative humidity;
No conductive dust, explosive gas, and can seriously damage the metal and insulation of the corrosive gas.
Safe operation & emsp;
, before starting the first check whether the water, gas, electricity is switched on, the following operation can be carried out when turned on after;
Operating personnel must make corresponding insulated shoes, gloves, etc.
The operator must have the corresponding electrical engineering knowledge.
Equipment repair, he has to pull out after the switch to determine the power off, and then to discharge processing, then hang up the maintenance, repair again and again, such as must be charged operation, must be the presence of two or more persons, but must not be allowed to take high pressure operation.
Before starting, first determine waterway is normal, equipment parts are allowed to boot normally.
Start with a filament, five minutes after second filament, again after five minutes, only can send high pressure.
Before send high pressure, determine output to adjust potentiometer in the minimum position, then send to high pressure, and the output voltage, the voltage to work.
Determine how the workpiece, can press the heat button, make the equipment work, but will never allow light to heat.
The abnormal situation such as work, equipment, must immediately disconnect the power supply, find out the reason, work again.
Equipment after the completion of the work, switch off the heating, and then disconnect and high pressure, and then close the filament, disconnect the power supply.
Equipment to stop working, have to wait five minutes later, disconnect the water again.
Equipment during the work, such as temporary have something must leave, must do it, people away from the machine stop, must not be allowed, no man machine is working.
Induction heating power supply in two of the technical details of high frequency induction heating principle of how to add equipment installed in the machine high frequency induction heating equipment
