Product Description:


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/8kHz100kW/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: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: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 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:What are the advantages of a vacuum furnace?
Energy consumption is lower than salt bath furnace. Modern advanced vacuum industrial furnace heating chamber is made of high quality heat insulation material and wall, which can concentrate electric heating energy into heating chamber with remarkable energy saving effect.
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:How to use industrial furnace equipment?
The protection device of the exposed transmission department shall be installed with the correct installation position. The structure is reasonable. The wire rope pulley of the furnace car shall be intact and undamaged. All the pulleys and sprockets on the furnace are in good condition, without defects and flexible in rolling.
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.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.
Q:What are the combustion equipments used in industrial boilers?
The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.
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.
