A, selected intermediate frequency furnace principle

1, considering the yield of each month. Tonnage of the election and the future development of intermediate frequency furnace.

2 , consider the single weight of the casting . Small castings do not need large tonnage of the intermediate frequency furnace

3 , consider the transformer monthly fee

4, when the power-saving furnaces IF

5, the line voltage of 380V frequency furnace, 575 V, 660V, 750V, 1000V and other models

B , classification of intermediate frequency furnace

1, divided by the supply voltage:

1. high pressure furnace, KGPS intermediate frequency power supply , 12- pulse intermediate frequency power supply , 24 pulse intermediate frequency power supply Above 660V power supply, power-saving features fast

2. ordinary furnace, with KGPS intermediate frequency power supply 380V power supply, features: high electricity costs

3 , one for two classification: 1 one for two parallel, features: low price, high electricity costs ,2 one belt two series, features: high price, power saving

4 according to the furnace shell points : 1 aluminum shell furnace . Features more faults

 2 steel shell furnace features less failure

Third, the intermediate frequency furnace tonnage is equipped with transformer power
