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
- Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.
- 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: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
- The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.
- 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 is industrial furnace masonry?
- Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.
- 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?
- No pollution to the environment, no need for three wastes treatment.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Industrial furnace masonry requirements are relatively high, industrial furnaces of different uses, whether material or masonry process, have strict requirements.
- 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?
- 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.
