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).

- 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.
- Q: What are the companies in the world that are currently engaged in metallurgical furnaces?
- Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
- 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: 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: How many kinds of industrial electric furnaces are there?
- Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
- Q: What are the advantages of a vacuum furnace?
- Energy consumption is lower than salt bath furnace. Modern advanced vacuum industrial furnace heating chamber is made of high quality heat insulation material and wall, which can concentrate electric heating energy into heating chamber with remarkable energy saving effect.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Industrial furnace masonry requirements are relatively high, industrial furnaces of different uses, whether material or masonry process, have strict requirements.
