What is what are the typical features of medium frequency heating furnace and USES in the metal parts production and processing industry, can use all kinds of metal hot forging heating quenching tempering annealing equipment, etc.
The medium frequency heating furnace is a very commonly used heating equipment.
So what is a medium frequency heating furnace, the working principle of intermediate frequency heating furnace is what?
And what are the characteristics and USES.
What is the medium frequency heating furnace & emsp;
Medium frequency heating furnace in simple terms, is through the electromagnetic induction eddy current in the metal surface melt metal heating equipment.
Medium frequency heating furnace by the medium frequency power supply cabinets, capacitor cabinets, heating furnace and other parts.
And intermediate frequency electric stove working in high voltage, high current, combined with the metal after the furnace to melt into a liquid, the temperature in the 1300 -
Intermediate frequency electric furnace
is mainly used in black and non-ferrous metals such as alloy steel, copper, aluminum and its alloy smelting, heat preservation, also can be used in the smelting of gold, silver and other precious metals.
Metal cylinder on alternating medium frequency current of induction coil, metal cylinder has no direct contact with induction coil, electric coil temperature is very low, but the surfaces are heated to redness, and even melt, and the redness and melting speed as long as adjust the strength of the size and current frequency can be achieved.
What is the working principle of intermediate frequency heating furnace & emsp;
Medium frequency heating furnace control power is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 HZ and 20 k HZ)
Power supply device, the three-phase alternating current (ac) power frequency, after rectification into direct current, then laid adjustable intermediate frequency electric current, direct current supply by capacitance and induction coil in through the intermediate frequency alternating current, generate high density magnetic field lines in the induction coil, induction coil, and cutting in cheng fang of metal materials, produce a lot of eddy current in the metal materials.
The vortex also has some properties of intermediate frequency electric current, i. e. , the metal itself free electrons in the resistance of the metal body flow to generate heat.
The characteristics of medium frequency heating furnace medium frequency induction heating forging furnace super small volume, portable, covers an area of only 0.
6 square metre, convenient and any equipment used;
Installation, commissioning and operation is very convenient, is quick to learn.
Can again within a very short time to reach the required temperature, greatly reduce the oxidation of metal;
Medium frequency heating phi above 15 bar, more diathermy, more uniform, more rapidly and can work 24 hours a day;
Energy saving environmental protection, diathermy more even fast, automatic feeding, greatly saves the cost;
To replace the furnace, so as to adapt to bar the whole heating or end heating of different requirements.
Mixer induction coil length is 600 mm or 800 mm, usually coarse fodder or long, induction coil is 1 m long, or even more than 1 m length, 5 - at the same time
10 when heated.
Easy replacement, induction coil, according to do not with the diameter of the workpiece, using different sizes of induction coil.
Mixer output frequency is 1 -
10 KHZ, according to the size of the heating workpiece diameter, design and capacitance induction coil, to achieve a different frequency, adapt to different material heating.
Is fine, the heating frequency, can guarantee diathermy, and obtain higher heating efficiency;
Coarse material, the lower frequency, ensure diathermy.
Mixer adopts pneumatic feeding method, for a certain bar, regulating equipment and power feeding rhythm, can automatically launch red-hot bar used for forging press, the operation is very convenient.
IGBT power components, the efficient combination resonance technology.
USES the low inductance circuit arrangement, USES the large scale digital circuits.
Pieces of heating speed, high production efficiency, less oxidation decarburization, save material and cost of forging die.
Due to the principle of electromagnetic induction medium frequency induction heating, the heat inside the workpiece itself, ordinary workers with intermediate frequency electric furnace work can be carried out immediately after the task of forging work continuously.
Don't have to worry about power outage or equipment failure caused by heating of the billet waste phenomenon.
Due to the heating mode heat up fast, so few oxidation, forgings and per ton KGPS thyristor medium frequency furnace than 20 - at least save steel raw materials
50 kg, greatly save electricity, every tons of steel heating, electricity 310 degrees.
Than KGPS thyristor medium frequency power saving 20%
Due to the heating way heating uniformity, core temperature small table, will not bring the net side pollution, no fever, power supply transformer substation, compensation capacitor not fever, do not interfere with other equipment work.
Reduces the size of the power supply transformer.
Uniform heating, tiny core table temperature difference, temperature control precision is high.
Induction heating of the heat inside the workpiece itself so uniform heating, core table is a very small temperature difference.
Application of temperature control system can realize accurate control of temperature to improve product quality and qualified rate.
The whole device is small, compact, put in hot forging machine, forging machine next to use very convenient.
Mixer superior working environment, no pollution, low energy.
The purpose of the medium frequency heating furnace heng Yang released new energy-efficient medium frequency induction heating for heating forging furnace can be used for the diameter Φ 12 -
80 Φ steel, stainless steel, copper, aluminum and so on the rules of the round bar, square or other shape MAO bad material such as continuous heating;
Standard parts industry and the stigma of pier, nut forming, valves and copper pieces of thermoforming lock industry, etc. ;
Can be used for overall heating, local heating can also be used for material, such as heating end, middle heating, etc.

Getting doesn't have to be expensive, time-consuming, or difficult. It all comes down to the right method and a steel melting induction furnace manufacturers continous casting machine in place.
Do you want continuous casting and rolling steel melting furnace? We also have aluminium shell iron scrap melting furnace. visit Induction furnace, Induction melting furnace manufacturer, induction furnace manufacturers to know more.
Hengyang Furnace focuses on three key elements—process, people, and technology—the authors found that people of two seemingly opposite cultures are able to work together in a project-based environment to complement each other and reap mutual benefits for a win-win result.
