an induction furnace uses induction to heat metal to its melting point.once molten, the high-frequency magnetic field can also be used to stir the hot metal, which is useful in ensuring that alloying additions are fully mixed into the melt.most induction furnaces consist of a tube of water-cooled copper rings surrounding a container of refractory material.induction furnaces are used in most modern foundries as a cleaner method of melting metals than a reverberatory furnace or a cupola.sizes range from a kilogram of capacity to a hundred tonnes capacity.induction furnaces often emit a high-pitched whine or hum when they are running, depending on their operating frequency.metals melted include iron and steel, copper, aluminium, and precious metals.because it is a clean and non-contact process it can be used in a vacuum or inert atmosphere.vacuum furnaces make use of induction heating for the production of specialty steels and other alloys that would oxidize if heated in the presence of air.
1.all-solid-state igbt frequency conversion and power adjustment, soft-switching responance dual-control and frequency automatic tracking technology is the reliability of guarantee.module and soft switching inverting technologies are used in the production of the generator, higher reliability can be achieved;
2.small size and portable, compared with scr controlled machine, only 1/10 working space is needed, greatly reduce occupation space;
3.high efficiency and energy saving:a high power factor and power efficiency within the scope of full power.
4.with wide frequency range from 1-20khz automatic trackin ability, no need adjustment at scene.
5.100% duty cycle, 24hours continuous working ability at maximum power.
6.constant output voltage or power control modes are alternative;
7.full display of output power, output frequency, output voltage and current.
8.the timer function:heating time and retaining time:0.1~99.9second.
the composing of medium frequency induction melting furnace:
1.medium frequency induction heating power supply
1.installation and operation can be very easily learned;
2.portable and light weight;occupies less than 1.0 square meters;
3.24hours no-stop melting ability;
4.high effiency, energy saving and environmental protection;
5.it's easy to change furnace to melt different materials.
characteristics of melting by medium frequency machine
1.better heating penetration and even temperature inside the melting metal.
2.medium frequency filed force can stir the melting pool to achieve better melting quality.
melting the maximum quantity by the recommended machine according to above data, the first melting when the furnace is cold, and it will take 20minutes fo the preheating, when the furnace is already hot, the melting time is about 20-30minutes per furnace.
