Advantages applications of models with Timer function of HF-25JQ、HF-35 HF-45
1. Heating power, retaining power, heating time, retaining time cooling time can be preset adjusted, this makes it possible to control the heating curve heating time.
2. It is suitable to use in the repeated heating or high speed heating of small parts;
3. When using in brazing, with proper timing parameters, rapid heating retaining can be achieved to keep the temperature while the brazing material is melted then to let the brazing material spread smoothly to form good joint.
Advantages applications of separated transformer
1. In these three series machines, the high frequency transformer is separated from the generator, with 6 meters connecting cable at least.
2. It is suitable to use in the dirty or corrosive surroundings, the generator can be put in a clean space to increase the reliability.
3. With the small size light weight of the separated transformer, it is convenient to use in the production line easily assembled inside the machinery or moved mechanism.
Working theory structure
In HF-25JQ, HF-35 HF-45 series machines, series oscillating circuit is applied, through high frequency transformer, low voltage high current power is output to go through the induction coil.
Inside these series machines, IGBT module our second generation inverting control technology has been used, that is the dual control inverting technology. In these new technologies, output power oscillating frequency are controlled independently. we use IGBT components high frequency voltage regulate control circuit to control the power we use IGBT components, series oscillating automatic tracing circuit to reach soft switching in the inverting course, all these make the machine to be more reliable make the machine possible to work continuously with 100% duty cycle.
Compared to machines with first generation technology, second generation technology is more suitable for large power machines to get higher reliability.
Due to the adopting of advanced technology, HF-25JQ, HF-35 HF-45 series machines are characterized by larger frequency range, smaller size, water cooled transformer, higher reliability lower repair cost.
Main application characteristics
These machines have many heating applications,such as
(1), Heat treatment of gear shaft
(2), Braze of diamond tools,millstone,cincture repair so on
(3), Braze of compound pan bottom
(4), Heat treatment of compound pipe
5), Pressing moulding of stainless steel wares
(6) Braze of woodwork cutters
(7), Metals smelting
(8), Braze of copper pipes(in air conditioner sanitary fittings).
Due to the adopting of our second generation inverting control technology, HF-25JQ,HF-35 & HF-45 series machines are characterized with high reliability low repair cost, are one of the most popular models have been used widely in every
How induction works
Induction is a flame-free, no-contact heating method that can turn a precisely defined section of a metal bar cherry red in seconds.
How is this possible
Alternating current flowing through a coil generates a magnetic field. The strength of the varies in relation to the strength of the current passing through the coil. The field is concentrated in the area enclosed by the coil; while its magnitude depends on the strength of the current and the number of turns in the coil.
Eddy currents are induced in any electrically conductive object- a metal bar, for example-placed inside the coil. The phenomenon of resistance generates heat in the area where the eddy currents are flowing. Increasing the strength of the the magnetic field increases the heating effect. However, the total heating effect is also influenced by the magnetic properties of the object and the distance between it and the coil.
