Application Scope
Steel Bar for Pre-stressed Concrete
Production and processing of PC steel bar (Steel Bar for Pre-stressed Concrete), quenching and tempering heat treatment of metal wire.
Function Structure
PC steel bar production line is complete automatic control: several sets of medium frequency/super audio frequency power supply accomplish pre heating, heating, quenching and tempering of steel bar online. Realize synchronization control of production line by several sets of inverters driving the mechanism.
There are totally four sets of heating power supply of PC steel bar production line, the power and frequency of which are designed to be: 600kW/8kHz, 200kW/30kHz, 200kW/50kHz, 300kW/8kHz. The power supply adopts parallel IGBT induction heating power supply. It is just because of online heating that there’re strict requirements concerning working status and synchronization control of the power supply.
The parallel IGBT 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. The inverter adopts high voltage large power IGBT module and large power fast recovery diode to form inverter power unit. The resonant tank circuit adopts parallel resonance.
The whole unit of equipment is composed of four sets of induction heating equipment, water cooling system, console, automatic control system and mechanism system.

- Q: Selection of heat preservation material for industrial furnace
- Ceramic fiber blanket can be used.Ceramic fiber blanket color white, regular size, set fire, heat insulation, insulation in one. Free from any binding agent.
- 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: Should the industrial furnace shell cool down?
- The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.
- 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 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?
- Masonry industrial furnaces refers to complete materials such as brick kilns in construction process.
- 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 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: Brief introduction to repair of industrial furnace
- The working condition of industrial furnace is very bad. It is affected by high temperature, slag erosion and burden wear. Therefore, its working condition changes quickly and its service life is short.
- Q: What is an industrial furnace pit?
- The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.
