Description: 0.5T power factor
The power factor of the series intermediate frequency furnace is high: ≥0.9 6 , because all the thyristors in the rectification part of the power supply are in the fully open state , the rectifier circuit is always in the all-on state, and the rising power is realized by adjusting the voltage of the series inverter bridge . Therefore, the entire operation process (including low power, medium power, high power) can ensure that the equipment is always in a high efficiency stage.
Parallel intermediate frequency furnace power factor is low: ≤0. 92 , because all the thyristors in the rectification part of the power supply are in a semi-open state (adding additional compensation according to the requirements of the national grid). The power regulation of the parallel line is adjusted by the rectification conduction angle, so At low power, the power factor of the power system is very low, generally between 40% and 80%; the high harmonics are large and seriously interfere with the power grid .
Second , the main purpose of the 0.5T series intermediate frequency furnace
0.5T series IF melting furnace is mainly applied to steel, iron, copper, aluminum and alloys, having a high melting efficiency, energy-saving effect, a uniform metal composition, burning small, quick temperature rise, easy temperature control and so, for various metal melt.
Third , 0.5T series intermediate frequency furnace consists of:
400kw series intermediate frequency power supply - steel shell furnace body - water cooled cable - remote console - ZXZ- 40T closed loop cooling tower.
Four , 0.5T series intermediate frequency furnace price summary table
The price of the 0.5T series intermediate frequency furnace is calculated according to the power of the intermediate frequency power supply and the volume of the furnace body. Different configuration prices vary. This price is for reference only. Contact us will have a very low price, please consult the specific price. Firs T furnace@gmail.com

Sixth , 0.5T series intermediate frequency furnace circuit diagram :
Seven , the reason for choosing 0.5T series intermediate frequency furnace :
(1) The whole machine can realize fool-like operation to avoid accidents caused by operational errors.
(2) The rectification inverter is completed by a power potentiometer and buffers the soft start. Self-judgment of the load state, if the load is short-circuited or open circuit, the zero-impact, micro-current lock-controlled inverter output can be used to avoid further expansion of the fault.
(3) High power factor, low harmonic interference. The power factor of the whole machine is comφ≥0.9 6 , no need to configure reactive power compensation and harmonic elimination device , and reduce investment in construction .
(4) The inverter pulse width and commutation dead time can be flexibly adjusted to suit various load frequencies.
(5) High start-up success rate : 100% start-up for any load condition , with high load adaptability: high power factor full load output even in the cold furnace (cold) state.
(6) Extremely high power saving effect: the relative parallel resonance rate is 20~30% , the reason is as follows
