Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of an electromagnet, and an electronic oscillator that passes a highfrequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor called eddy currents. The eddy currents flowing through the resistance of the material heat it by Joule heating. In ferromagnetic materials like iron, heat may also be generated by magnetic hysteresis losses. The frequency of current used depends on the object size, material type, coupling and the penetration depth.
An important feature of the induction heating process is that the heat is generated inside the object itself, instead of by an external heat source via heat conduction. Thus objects can be heated very rapidly. In addition there need not be any external contact, which can be important where contamination is an issue.
Compared with conventional coatings removal methods using grit or water, the Fortec Heat Induction system for coatings removal offers many advantages. To start with, it offers a safe, fast and silent removal process. The Lining & PFP protection comes off easily in strips or pieces that can be bagged for disposal without risk of contamination to air, ground or water.
Protective Coatings with thickness up to 1-25 mm are removed quickly and efficiently, including epoxy, rubber, fiberglass, PFP's, etc. Tailored automatic solutions can be arranged upon request.
Above all, use of Fortec Heat Induction system for protective coatings removal gives no grit or water deposits. Therefore, transport cost and emissions is reduced to a minimum.
Most importantly our removal system is safe for the operator or nearby workers carrying out other maintenance or inspection work.
