Application Scope
Cold rolled ribbed steel bar annealing equipment, wire annealing
Function Structure
Cold rolled ribbed steel bar annealing production line is complete automatic control: two sets of medium frequency power supply accomplish annealing of ribbed steel bar online. Realize synchronization control of production line by several sets of inverters driving the mechanism.
There are totally two sets of heating power supply of cold rolled ribbed steel bar annealing production line, the power and frequency of which are designed to be: 500kW/8kHz，100kW/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 two sets of induction heating equipment, water cooling system, console, automatic control system and mechanism system.
Technical features
Ø Excellent heating power supply design
1. Power supply cabinet and heating tank circuit adopt independent design with compact structure and small size which is convenient for site layout.
2. The heating inductor is characterized by high heating efficiency of whole line and stable heating technics by optimization design.
3. The power supply selects DC chopper mode to ensure the grid side power coefficient≥0.92 and a relative lower harmonic content.
4. Adopt CPLD full digital control system, automatic fixed angle, high precision of phase-lock and wide scope of phase-lock. Perfect protection function, reliable working and low failure rate.
5. High standard power supply electromagnetism compatibility design and closed cabinet design to meet the strict requirements at site.
Ø Perfect production and design
1．Rapid increasing temperature and stable and precise temperature control to ensure a refinement of crystal inside rolled ribbed steel bar and greatly enhance physical property of steel bar, to meet high strength, high ductility and high anti-seismic mechanical property.
2．Adopt all Chinese operation interface and matched with programmable controller, realizing precise control to rolling mill speed and temperature. The system adopts table look-up method to set and store different wire and speed which is very convenient.
3．Full line fault alarm analysis system, which can be displayed on heating operation interface, can find the source of trouble in the first time (any abnormal operation of the line can be displayed on the interface).
4．Adopt infrared thermometer to measure the temperature of wire exit, which is convenient to adjust power and temperature.
5．Adopt special material for barrel type conduct at entrance of capacitor cabinet, select stainless steel guide wheel as the shape of Chinese character “品”between the inductor, to make location of center line for steel bar.

- 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: Should the industrial furnace shell cool down?
- The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.
- 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 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 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 are the advantages of a vacuum furnace?
- High degree of integration of mechanical and electrical. On the basis of the improvement of temperature measurement and control accuracy, the workpiece movement, air pressure regulation, power adjustment can be programmed in advance, and quenching and tempering are carried out according to the steps.
- 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: 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 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.
