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?
- 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: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
- The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.
- 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?
- Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.
- Q: What's the role of anchor bricks in industrial furnaces?
- These layers need to be joined and anchored. Anchor brick is this role. The heat insulation layer at the horizontal section of the flue is mostly a narrow cavity.
- Q: How many kinds of industrial electric furnaces are there?
- Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.
- 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?
- From the way: industrial furnace (electricity, natural gas, gas, induction heating is considered electricity), boilers (coal, all kinds of hot exhaust gas, a variety of gas, seemingly less electricity).
