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?
Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.
Q:What is the difference in structure between industrial furnace and boiler?
Industrial furnace: main heating, steel and other metal materials, or ore and other materials. An industrial furnace of higher temperature, such as forging or heat treatment. Therefore, the energy consumption is large, and the insulation layer is designed to be thicker, and the structure is designed for the final purpose of the production purpose, the product process and the production efficiency.
Q:How many kinds of industrial electric furnaces are there?
Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
Q:What is the difference between industrial furnaces and boilers?
A boiler is a mechanical device for heating water into hot water or steam by the use of heat from fuel or other sources of energy. The original meaning of a pot is a water container heated by fire. The furnace is the place where the fuel is burned. The boiler includes two parts, the cooker and the furnace.
Q:How to use industrial furnace equipment?
The protection device of the exposed transmission department shall be installed with the correct installation position. The structure is reasonable. The wire rope pulley of the furnace car shall be intact and undamaged. All the pulleys and sprockets on the furnace are in good condition, without defects and flexible in rolling.
Q:What is an industrial furnace pit?
In twentieth Century 50s, coreless induction furnaces were developed rapidly. Later, electron beam kilns, using electron beams to impact solid fuels, strengthen the surface to heat and fuse materials with high melting point.
Q:Selection of heat preservation material for industrial furnace
Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.
Q:What are the combustion equipments used in industrial boilers?
The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.
Q:Brief introduction to repair of industrial furnace
Compared with other equipment, industrial furnace repair has many characteristics: more repair times, more maintenance costs, more non-standard equipment and unsafe factors.
Q:Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.
