HOW INDUCTION HEATING WORKS:

Frequency conversion electromagnetic induction heating or induction heating for short is a method for heating metal materials by converting power frequency power supply into that of specific range based on the principle of electromagnetic induction. It is mainly applicable to the metal hot working, heat treatment, welding and melting.

Basic components of induction heating system include induction coil, AC power source and work pieces. Induction coil can be fabricated into different shapes as per different heated objects. The coil is connected with the power source providing alternating current for coil. The alternating current possessed by the coil can create a alternating magnetic field passing through the work pieces to produce eddy flow as required by heating.

In a basic induction heating setup shown in Right Figure, a solid state RF power supply sends an AC current through an inductor (often a copper coil),and the part to be heated (the workpiece) is placed inside the inductor. The inductor serves as the transformer primary and the part to be heated becomes a short circuit secondary. When a metal part is placed within the inductor and enters the magnetic field, circulating eddy currents are induced within the part.

As shown in follwoing Figure , these eddy currents flow against the electrical resistivity of the metal, generating precise and localized heat without any direct contact between the part and the inductor. This heating occurs with both magnetic and non-magnetic parts, and is often referred to as the "Joule effect", referring to Joule's first law – a scientific formula expressing the relationship between heat produced by electrical current passed through a conductor.

Secondarily, additional heat is produced within magnetic parts through hysteresis – internal friction that is created when magnetic parts pass through the inductor. Magnetic materials naturally offer electrical resistance to the rapidly changing magnetic fields within the inductor. This resistance produces internal friction which in turn produces heat.

In the process of heating the material, there is therefore no contact between the inductor and the part, and neither are there any combustion gases. The material to be heated can be located in a setting isolated from the power supply; submerged in a liquid, covered by isolated substances, in gaseous atmospheres or even in a vacuum.

THE TECHNICAL PARAMETERS OF THE INDUCTION HEATER:

APPLICATIONS IN OIL AND GAS INDUSTRY:

Oil and natural gas suppliers rely on induction heating equipment for many different production processes:

• Pipe end stress relief

• Soldering of rock drilling tools

• Coupling coating

• Forming pipe ends for bottles and cylinders

• Heating the ends of sucker rods

• Seam annealing

• Preheat for pipe forming

• Pipe straightening

THE ADVANTAGES OF THE INDUCTION HEATING:

Innovative induction heating technology offers many advantages for the oil and gas industry:

• Energy saving: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to ensure the appropriate temperature as required by each part of work piece), fast warming and limited oxic horizon, and can guard against any waste after annealing.

• Reduced processing time: it can be started to perform heating operation on condition that water and power supply is available. the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control)

• Temperature control:it is applicable to control the temperature for heating work pieces as per the preset heating time, and thereby control the heating temperature at a certain technical point.

• Control and localized heating

• Possibility of integration into assembly lines

• No physical contact: With induction, the part to be heated never comes into direct contact with a flame or other heating element; the heat is induced within the part itself by alternating electrical current.

• Improved working environment : Induction heating systems do not burn traditional fossil fuels; induction is a clean, non-polluting process which will help protect the environment. An induction system improves working conditions for your employees by eliminating smoke, waste heat, noxious emissions and loud noise. Heating is safe and efficient with no open flame to endanger the operator or obscure the process. Non-conductive materials are not affected and can be located in close proximity to the heating zone without damage.
