Description

MIKROSHA-15-8-VF forging induction metal heater is designed for heating metal before forging and bending, hot forging, hardening, for soldering cutters, welding and brazing parts and many other similar works with metal, industrial or artistic processing. Power supply from single-phase 220-240 V 50 Hz network suggests its use in small workshops, private garages and forges. Induction heating of blanks by magnetic field will make your work more comfortable and safe compared to gas or coal furnace, in addition, the induction furnace significantly reduces the time of heating the metal to the desired temperature, being only tens of seconds. The temperature can reach over 1300 degrees Celsius and even melt. C, even to the point of melting.

Forge heater MICROSHA-15-8-HF has the maximum output oscillating power of 15 kVA, which fully corresponds to the widespread Asian models such as HF-15, JL-15, LSW-16KW, UM-15AB, GHF-15-(7kW), etc. Actually, the very concept of vibrational power is introduced incorrectly, and in practical terms does not make any sense and means the current in the circuit multiplied by the voltage on the coil of the oscillating circuit, i.e. inductor. Practically what matters is that all these models, when powered by 230 volts, consume a maximum current of up to 35 amperes, which equals 230*35 = 8 kVA. This load is acceptable enough for a good household or garage power and Mikrosha-15-8 is well fit into the range of these devices for induction heating as the total power consumption and heating efficiency of the metal. Having a moderate price and power equal to the above mentioned devices, the induction heater MICROSHA-15-8-VF has the modest size and weight of only 7.2 KG, which is much, 3.5 times less than the analogues, which is why it is called "MICROSHA".

The induction heater MIKROSHA-15-8-HF has air cooling of the heat sinks of transistors, resonant capacitors and the power transformer, which is provided by two fans. Water cooling is supplied only to the exchangeable inductors. Thus, over time, if the tubes of inductors become encrusted, it is not necessary to overhaul the entire apparatus, just make a new inductor, without disassembling the apparatus itself. To achieve a small transformer heating, high-frequency wire LELD-155 is used as windings, folded twice and consists of 1075 lacquer-insulated strands of 0.071 mm diameter, twisted into pigtails. The cost of such a wire is appropriate. The core of the transformer is nanocrystalline and consists of several rings folded together. As an indication module we used in the microshield a ready made voltmeter-ampere-wattmeter made in China. This little device does not affect the operation of the circuit and displays the network voltage, current, power factor, active power consumption, which of the total consumption actually goes into the heating, as well as acting as a power meter, showing how many kilowatt-hours per shift screwed machine. In addition, it has a nice design and acceptable accuracy of readings. Heating can be controlled both by a switch on the front panel and with a foot pedal. Naturally, all the necessary protections are available in the microchip: against overheating, short-circuiting turns of the inductor, etc. Power of forging induction heater MICROSHA-15-8-VF is enough to heat rod Ф=16 mm inductor with diameter Ф=20 mm, blanks Ф=25 mm inductor with diameter Ф=30 mm to be melted. Copper tubes, placed in inductors, are heated until softening, but the power absorbed by copper and aluminum blanks is insignificant. Regarding power, it is necessary to understand the fact that the maximum power is released in the metal by eddy currents only in the first seconds of heating, until the temperature reaches the Curie point (750 degrees C). With further heating of the billet, the power consumption decreases because the metal loses its magnetic properties, which can be seen on the display of the unit, but this does not prevent it from reaching a temperature of over 1300 degrees C. In this case, the oscillating power in the inductor itself does not change. What does change is the degree of withdrawal of this power by the object being heated. The more power is taken for heating, the more is pumped into the resonant circuit by the generator transistors from the power supply - that is, from the network. Operating frequency range of the heater MIKROSHA-15-8-HF is 20-60 kHz. Devices in this frequency range work with short inductors with small inductance and a small number of turns to provide a high power density per square centimeter of the surface. This is well suited for rapid heating of the metal surface for hardening the ends of shafts, gears, with a gradient of heating temperature along the depth. To harden long shafts it is necessary to arrange a feed mechanism, for example from an old lathe and an open-ended spreader located immediately behind the inductor.

For through heating of long workpieces and as melting furnaces, long multi-coil inductors are used, with an inductance of 10 or more times greater. Therefore, medium-frequency devices are used for this purpose. In our line of models this is MIKROSHA-15-8-SF, which operates in the frequency range of 8-30 kHz.
