1, intermediate frequency forging heating furnace of intermediate frequency forging heating furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency (
More than 300 hz - 1000 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.
2, intermediate frequency & emsp; what are the characteristics of forging heating furnace?
1, the standard form of quick change type heating furnace.
2, local heating induction heating is easy to make.
3, according to the different hot pressing technology has taken a different way of induction heating.
4, for heating is larger the diameter of the workpiece, medium frequency induction heating furnace in order to improve the lining life, set within the furnace lining with water-cooled guide rail, the water-cooled guide rail surface spraying with tungsten carbide coating, can significantly improve the service life of the water-cooled guide rail.
The design of the sensor using the self-developed 'sensor optimization design CAD software, the sensors dozens of parameter optimization design, and with reference to foreign sensor design concept, we design and manufacture of sensors high heating efficiency, the furnace length, small loss.
3, intermediate frequency forging main configuration and performance of intermediate frequency induction heating furnace forging heating 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.
Induction coil length is 600 mm or 800 mm, usually coarse fodder or long, even for 1 m long induction coil, or 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.
The output frequency of 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.
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 use of highly efficient combination resonance technology.
USES the low inductance circuit arrangement, USES the large scale digital circuits.
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 entire device small, compact, put in hot forging machine, forging machine next to use very convenient.
Superior working environment, no pollution, low energy.
4, intermediate frequency forging heating furnace brand how to select & emsp;
Intermediate frequency forging heating furnace brand how to choose, need to the products under the brand, consider the following factors.
First of all, the correct selection of frequency.
The frequency of the workpiece diameter, the greater the choose device should be lower.
Second, the correct selection of power.
The greater the power, the faster the heating, the price is higher accordingly.
We mentioned here refers to the power output power and power oscillation.
The output power is the load power of the equipment, power oscillation is actually about 60% of the output power.
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.
