Description: 1. 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 .
First, the main purpose of 0.25T series intermediate frequency furnace
0.25T 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.
Second, the composition of 0.25T series intermediate frequency furnace :
200kw frequency power supply connected in series - aluminum furnace shell - Remote Control Box - ZXZ- 20T closed loop cooling tower.
Third, 0.25T series intermediate frequency furnace price summary table
The price of the 0.25T 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. Firstfurnace@gmail.com
