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.
- Heat treatment furnace is mainly for the mechanical processing and casting industry workpiece annealing, quenching, carburizing, quenching and tempering, heat treatment equipment.
- Q: What are the companies in the world that are currently engaged in metallurgical furnaces?
- There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.
- 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: 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: 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 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: How to use industrial furnace equipment?
- When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.
- 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: What is an industrial furnace pit?
