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

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
- In the neutral and oxidizing atmosphere, the tensile strength, toughness and fiber structure can be maintained for long term use. The temperature is 950-1400 centigrade. Excellent chemical stability; excellent thermal stability; excellent tensile strength; low thermal conductivity; low thermal capacity; excellent sound absorption and noise reduction performance.
- Q: Should the industrial furnace shell cool down?
- If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.
- 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?
- Main auxiliary equipment for general boilers:1. domestic appliances 2. civilian gas boiler 3. industrial gas furnace.
- 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: 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?
- The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.
- 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?
- 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.
