Product Description:

 

Application Scope

 Metal heat penetration, hot forging, heat preservation, composite brazing, metal workpiece shrinkage fitting, metal quenching, annealing, normalizing and tempering.

 

Function Structure

The parallel IGBT medium/superaudio induction heating power supply adopts AC-DC-AC variable frequency power supply structure. The rectifier of the power supply adopts 3-phase thyristor rectifying or diode and IGBT chopper mode. 12-pulse rectifier can be adopted for large power equipment to decrease grid side harmonic current. The inverter adopts high voltage large power IGBT module and large power fast recovery diode to form inverter power unit, to realize large power output through the superposition of inverter power unit. The resonant tank circuit adopts parallel resonance, and parallel, multivoltage or transformer mode can be selected for different load heating.


The whole unit of equipment is composed of parallel induction heating power supply, resonant tank circuit, circulation soft water cooling system, console (optional), automatic control system (optional).

 

Technical Features

 

       Ø Perfect structure design

1. Integration design of switchgear rectifying cabinet and inverter output cabinet, with compact structure and small size.

2. DC chopper mode is selected to ensure the grid side power coefficient≥0.92 and a relative lower harmonic content.

3. Power combination of the inverter bridge is accomplished by the way of power unit superposition, which is convenient for installation and repair. Each IGBT power unit is designed to be 100kW or 200kW.

4. High standard electromagnetism compatibility design, electromagnetism radiation meets national standard. Closed cabinet design, meeting rigor environmental requirements on site.

5. Resonant tank circuit mode is an independent design as per users actual requirement with convenient and flexible site layout.


Ø  Full digital control system

1.3-phase rectifier (DC chopper) adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.

2. Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.

3. The power supply has perfect protection function with reliable working and low failure rate.

 

Ø HMI and fault diagnosis system (optional)

1. Adopt PLC and touch screen to form perfect HMI system.

2. Realize integrated automatic control of power supply system.

3. Fault display and diagnosis system.

Q:What is the difference between industrial furnace masonry and ordinary masonry?
Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.
Q:What's the role of anchor bricks in industrial furnaces?
The wall of an industrial furnace or flue is mainly composed of an inner lining layer, a heat insulating layer and an outer wall layer. The lining is a refractory brick, and the outer wall is an ordinary sintered brick.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
Basically, no industrial furnace manufacturer can do all types of stoves.Often associated with the industry is very large,so your ranking is basically meaningless.
Q:What is the difference in structure between industrial furnace and boiler?
At the same time, the working environment is relatively poor, the structure should be sturdy and durable, the transfer mechanism (generally) to stable and durable low failure rate, the insulation layer must be thick enough and the economy, the steel structure housing materials used to be enough.
Q:What is the difference between industrial furnaces and boilers?
Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.
Q:What is industrial furnace masonry?
Before masonry construction, the pre process and parts that may affect the quality of masonry work shall be re tested,masonry construction shall be carried out according to the datum central line and the datum elevation.
Q:Why does the burner of industrial furnace burn occasionally?
The flameout protection system is made up of burner controller, electromagnetic valve and flame detector, and the flame detection mode is mainly based on the two forms of ultraviolet detection and electrode detection. By utilizing the electric conductivity of the flame, the circuit path of the combustion process generates a weak current, and when the signal amplifier is amplified, the flame is induced to exist, and the small power burner adopts the detection mode more, and is economical and practical.
Q:What is an industrial furnace pit?
The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
Q:Should the industrial furnace shell cool down?
Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.
Q:How to use industrial furnace equipment?
If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
