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 between industrial furnaces and boilers?
- Industrial kilns and industrial furnaces are collectively referred to as industrial furnaces. Industrial furnaces mainly refer to devices that heat materials by combustion reactions.
- 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?
- 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 are the combustion equipments used in industrial boilers?
- The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.
- Q: What is industrial furnace masonry?
- Pre construction and recording shall be carried out on complex and important parts of industrial furnaces,masonry of all kinds of masonry shall be made with staggered joint masonry.
- Q: What's the role of anchor bricks in industrial furnaces?
- Anchorage brick is a new type of anchor brick relates to an industrial furnace, in particular to anchor brick of an industrial furnace roof, including column hanging end and the anchor structure, opened in the anchor on the surface of the spacing of the grooves in the anchor on at least one surface is arranged along the length direction ribs is provided with ribs, the ribs of the reinforcement and anchorage tension, tensile and flexural strength was obviously improved, the stress generated in the groove at the bar at the barrier can not continue to transfer, so the anchor brick of this kind of structure is not easy to break.
- 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: 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: Brief introduction to repair of industrial furnace
- Although the number of industrial furnaces in general machinery plants is not large, the number of large repairs per year accounts for 16%-20% of the total number of repairs for all equipment, and the large repair costs account for about 18%-25% of the total repair cost of all equipment.
- Q: What is an industrial furnace pit?
- Later, a chamber kiln with a semi closed or fully enclosed kiln made of refractory bricks can be used as fuel for coal, gas or oil, and electricity can be used as heat source. The workpiece will be heated in the kiln hearth.
