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: Should the industrial furnace shell cool down?
- Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.
- 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 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: 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: 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: 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 advantages of a vacuum furnace?
- No pollution to the environment, no need for three wastes treatment.
- Q: What is the difference in structure between industrial furnace and boiler?
- At the same time, the working environment is relatively poor, the structure should be sturdy and durable, the transfer mechanism (generally) to stable and durable low failure rate, the insulation layer must be thick enough and the economy, the steel structure housing materials used to be enough.
- 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.
