Introduction and application

This is the device converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting and is applicable to melting, heating or holding of steel, copper, aluminum, zinc, tin, nickel silver and other ferrous or nonferrous metal and alloy material, as well as heating treatment prior to forging, sintering and tube-bending forming in casting and melting industries.

Performance and features

1. Zero-voltage scanning soft start, start or stop at any time under any state without impact on power supply;

2. Speedy melting, low production cost, low pollution, conforming to environmental protection requirement;

3. Melting directly from low temperature, available for fully emptying of solution, easy change of category of melting material;

4. Flexibly adjustable power, easy and continuous smooth adjustment, easily controllable temperature, low oxidization loss, uniform

metal content;

5. Furnace shell with cast aluminum ally or steel shell construction, small footprint, easy overturn body, available for selection of electric,

manual, hydraulic or other overturn mode as needed;

6. Complete set equipment can realize full automatic remote control, also including PLC programmable controller and HMI man-machine interface or industrial control computer system and industrial control configuration software and all kinds of sensors, etc. Can realize automatic constant temperature, automatic oven, anti wear furnace alarm, such as automation, use more secure, more convenient!
1 Automatic constant temperature function:Values can be preset liquid temperature requirements, one-click startup and attain the goal of automatic constant temperature; Compared with the traditional artificial temperature control, automatic constant temperature function will save time and more sensitive and more accurate, easier to control liquid temperature and oxidation burning loss less, metal components uniform casting product quality is better;
2  Automatic heating lining function:Heating lining is a relatively complicated and long process of temperature rise curve, to extend the service life of intermediate frequency furnace hearth, reduce production cost, the right build furnace lining technology is very important. The function of automatic lining of innovation, can according to the requirements of the different refractory lining temperature, to preset required by the different stages of heating lining temperature and time; PLC according to the preset time and temperature values, one-click start, automatic matching and stepless regulation of intermediate frequency power, the size of the control of heating speed, prevent lining cracks, and achieve the goal of automatic lining curve. Is to avoid the artificial misoperation and at the same time reduce the labor time and intensity of the workers.
3  Prevent wear furnace alarm function: prevent alarm system working principle is: wear furnace chamber of a stove or furnace use time to a certain degree, the wall will gradually thinning, the current will vary according to the furnace wall, after the current rate reaches the preset value will make alarm to remind in advance, then automatically cut off the power and predict wear furnace and achieve the goal of safe production in advance.

The latest model of Hengyang company"One-drag-two IF Induction Melting Furnace"with one set of IF power supply drag two furnace body work at the same time.
Only need to adjust the power button(or Digital operation screen),can achieve the power distribution between the two furnace.
The total power of the medium frequency power supply can be arbitrary distribution between two furnace body, to achieve one furnace for melting another furnace for holding effect, continued uninterrupted melting mode. greatly improve the production, energy saving practical, won the majority of customer acceptance and love.

 

Main Models And Technical Parameters

 

1 Melting time and power consumption/ton is important to equipment power, raw material shape and weight, operator's skill level and other elements.

Above sheet"per ton consumption (KWH/T)" is a common KGPS parallel intermediate frequency power supply consumption, new technology KGCL series intermediate frequency power supply can saving 15% or more.
2 Complete set configuration: Power supply cabinet, capacitor box, Overturn control box, Furnace body (Steel shell or aluminum shell),hydraulic station ( Or Reduction box with stent ), water cooled cables etc;
3 The above data is of standard model. We also provide customized non-standard products with different power or melting speed.

 

Hengyang IF Furnace Selection Guide
1,Ordinary KGPS IF parallel power supply,IGBT series IF power supply And the latest model of KGCL series IF power comparative selection
1,Ordinary KGPS Silicon Parallel Inverter IF Power Supply
The advantage is:The past few decades has been the most widely used, low price, easy maintenance, Reasonable price of accessories.
The disadvantage is:High energy consumption, per ton of molten iron power consumption is about 700 KWH/T.Adjust the DC voltage mode control power, the power factor is low(≤0.90),harmonic interference substation reactive power compensation capacitor running with varying degrees of impact. 

2,IGBT series IF power supply inverter 
The advantage is:The rectifier using full-wave rectifier,LC filter using capacitors and inductors way that the power factor of over 0.96,without harmonic interference.Inverter part adopts series inverter working mode,Work load in the case of the high-voltage small current,Copper loss small and greatly improving the efficiency. Per ton of molten iron power consumption is about 550 KWH/T.
The disadvantage is:IGBT IF power supply to the work environment request high,Less stable, easily damaged, expensive repair costs.
3,KGCL SCR series inverter IF power supply
KGCL SCR series inverter power supply inherit the above two kind of product advantages,Using full-wave rectifier power,In the whole work procedure rectifier always in full open state (equivalent to diode rectifier);The power factor of the device is always at the highest state(0.96).Does not produce high harmonics,no pollution to electric network,Do not affect substation reactive power compensation capacitor operation.KGCL than KGPS Silicon Parallel Inverter IF Power Supply saving of about 15%, Per ton of molten iron power consumption is about 550 KWH/T,Moreover, the spare parts Reasonable price and easy to buy easy to repair.
KGCL SCR series inverter IF power supply is our company focus on promotion of intermediate frequency furnace energy saving latest products.
2,Aluminum Shell furnace and Steel Shell furnace Selection
Aluminum Shell furnace: Inexpensive, easy maintenance, convenient observation. The disadvantage is low efficiency, electromagnetic radiation unshielded.
Steel Shell furnace: Made of high quality steel welding,Leakage-proof furnace alarm device,inductor around the yoke closure,Covering more than 65%.Because of the Small magnetic leakage,High efficiency,Steel shell furnace than aluminum shell furnace save nearly 5% energy consumption.

Equipment cooling mode selection
1,Closed Cooling Tower (Recommended use)    
1   Light weight and small footprint available for free relocation,available for direct use requiring no pool,pump and piping,etc.to save huge and complex water cooling facilities and saving workshop land.
 2   Enclosed soft water circulating cooling to prevent piping block caused by sundries,protect electric components against scale so as to decrease fault rate of IF,HF and other heating equipment greatly and prolong service life.
 3 Automatic digital display of temperature,energy efficient and environmental protection,easy installation,operation and maintenance.
2,Water tank + water pump+cooling tower 

 

The water in the water tank through the pump pressurized into the equipment, the flow back to the pool to recycle. The heat of water send out through the cooling tower, cooling tower with strong winds will be circulating water cooling, can effectively increase the heat dissipating capacity, reduce the user's pools.

 

 

3, Water Tank+Water Pump  
The water in the pool through pump pressurized into the equipment, the water recycled back to the reservoir. By flowing water, the natural distribution of heat.
1  Different power and use of equipment, cooling water required is not the same; our technicians will provide you with the data to match the size of the pool or cooling tower capacity as needed equipment.
