China medium frequency induction copper

melting furnace with energy saving advantage​

Unique new type patent for thyristor and capacitor uniform current

1. Power saving advantages:

Currently, thyristor serial-connected electric furnace is most widely applied in casting industry and it is also one of the lowest power consumption devices with a power factor of over 0.95. Compared with parallel-connected thyristor types , its power efficiency is much higher and power can be saved 20% higher than them.

2. Environmental advantages

Thyristor serial-connected equipment is durable and it has no special requirements for working environment, it can be applied under various environments with high safety performance, and it is also provided with various protective measures such as water pressure detection and temperature detection for water pipeline.

3. Speed advantage

Fast smelting speed and low power consumption are also the most unique advantage of thyristor serial-connected smelting system.

4. Low failure rate

Failure rate is very low and malfunctions hardly occurs within five years, even if any minor problems occur, maintenance is very simple and convenient, so this is one of the reasons why it is widely praised in this industry.

Technical advantages:

Mature technology, no high harmonics, maximum power factor, power factor can be over 95%, power compensation devices and harmonic elimination device are not needed any more.

Safety Advantage:

01 Hydraulic lock for furnace

Prevent sudden slipping down of furnace body due to oil pipe fault .

02 Detecting system for molten iron leakage out of furnace

Direct current voltage is provided between induction ring and bottom electrode to detect the resistance value of furnace lining, it is not necessary to install a stainless steel wire at the inside of induction ring , preventing molten iron explosion accident.

03 Interlock of power supply cabinet door

Electric panel shall immediately cut off power supply if door is opened when equipment is running , avoiding electric contact accident.

04 Protection against accident due to high temperature of water and water leakage

Avoid furnace explosion accident by detecting water temperature, water pressure and water flow.

05 Grounding protection

Conduct the inducting electricity existing on the cabinet door into the ground ,Avoiding electric contact accident

06 drop-roof hood of furnace

Prevent workers from falling when tilting the furnace

07 Emergency power supply

When the electricity is suddenly cut off, start the electricity generator group in time to provide power supply for water circulation of furnace, hydraulic system, lighting and moving lifter , preventing circulation water of furnace from getting very high to damage induction ring, ,therefore avoiding accidence.

08 Resin-poured impedance with empty core

Wholly poured by epoxy resin , safer application

Technology Features:

Reliable ! High Efficiency ! Energy Saving!

1. Select first class electric elements , scientific layout, reasonable structure design, guaranteeing optimum running status of the whole system

2. Thick raw material, reasonable match between induction ring and capacitor, intelligent type digital main control board, constant output and high efficiency power factor are guarantee for quick melting speed.
