Fourth, what is the difference between high frequency heating furnace and medium frequency induction heating furnace?
High-frequency heating furnace: current frequency is 100 ~ 500 kHz (kiloher), suitable for melting 1-5 kg of precious metals, fast, cheap, small size. Medium frequency induction heating furnace: current frequency is 500 ~ 10000 Hz (h), melting 5 kg - 60 tons of various metals, featuring fast speed and high efficiency -large volume, mature technology, large output power and low failure rate.
What is a high frequency induction furnace?
High-frequency induction furnace is also known as high-frequency heating machine, high-frequency induction heating equipment, high-frequency induction heating device, high-frequency heating power supply, high-frequency power supply, high-frequency electric furnace. High-frequency welding machine, in addition to medium frequency induction heating equipment, ultra-high frequency induction heating equipment. The scope of application is very wide.
5. What is the difference between high frequency induction heating and medium frequency induction heating?
First, the frequency range is different:
( 1 ) Intermediate frequency: The frequency range is generally around 1 kHz to 20 kHz , and the typical value is about 8 kHz .
( 2 ) High frequency: The frequency range is generally 40 kHz to 200 kHz , and is usually 40 kHz to 80 kHz .
Second, heating thickness
( 1 ) Intermediate frequency: heating thickness is about 3-10mm .
( 2 ) High frequency: heating depth or thickness is about 1-2mm .
Third, the scope of application
1 ) High frequency is suitable for quenching or welding, high frequency, heating from the outside to the inside, applied to surface heat treatment equipment.
2 ) The intermediate frequency is suitable for forging and diathermy, the frequency is low, and it is heated from the inside to the outside, and the heat is more uniform.
3 ) The choice of medium frequency heating or high frequency heating should be based on product design requirements. Temperature control is determined by reasonable process parameters. It does not exist better. The key is whether it can meet product requirements.
4) Intermediate frequency 200hz-10000hz : high frequency 10000hz or more. The intermediate frequency is suitable for overall heat transfer. High frequency is applied to the surface quenching. The medium and high frequency is selected by a heating process with a heating material. (If the surface is high frequency, the surface will be red first; when the medium frequency is heated, it will start red from the inside)
What is the difference between a high frequency induction heater and an ultra high frequency heater ?
This is related to the output oscillation frequency of the induction heating machine: the frequency of the high frequency is 30-80KHZ , the frequency of the ultra high frequency is 200-500KHZ and 0.5-1.1MHZ , depending on how much the workpiece needs to be determined or UHF heating. machine
Sixth, how to solve the common problem of ignition of medium and high frequency induction coils?
The coil here refers to the induction coil of the high frequency induction furnace, which is spirally wound from a hollow copper tube. The sparking of the coil occurs between the ytterbium and the ytterbium of the copper tube or between the copper tube and the yoke. Due to the insulation failure, a short-circuit discharge is formed under the action of the voltage, and the spark of the sputum is visible (commonly known as sparking). In the case of continuous arcing (commonly known as arcing).
Induction coil ignition will bring a lot of harm to the equipment, mainly reflected in the following aspects:
1 severely reduce the operating efficiency of the equipment, increase the power consumption and time of melting / heating;
2 The large current caused by arcing is extremely easy to burn thyristors and other important power components;
3 Pulling the arc causes equipment failure or wearing the furnace to bring great safety hazards to the operator;
4 Increase equipment failure rate, increase operation and maintenance costs, reduce enterprise production efficiency, and cause enterprises to lose high profits.
