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

- 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 are the advantages of a vacuum furnace?
- No pollution to the environment, no need for three wastes treatment.
- Q:What's the role of anchor bricks in industrial furnaces?
- These layers need to be joined and anchored. Anchor brick is this role. The heat insulation layer at the horizontal section of the flue is mostly a narrow cavity.
- Q:Why does the burner of industrial furnace burn occasionally?
- The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.
- 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: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 many kinds of industrial electric furnaces are there?
- This series of electric furnace is made of super light refractory fiber. The electric stove and the temperature control cabinet matching use, the controller may automatically or the manual control electric stove temperature, may press the user request to provide the computer table or the computer control, does the multielement temperature measurement, guarantees the product quality. This series of electric furnaces are periodical operation type electric furnaces.
- 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 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: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.
