Abstract

The invention discloses a method and a device for removing electromagnetic induction type metallic surface coating. The scheme adopted by the invention is that high-frequency current generates an induction magnetic field and a current vortex on a metallic surface via an electromagnetic induction coil, and further a coating is separated from the metallic surface under an appropriate temperature. The device comprises an induction power supply main frame (1), a relay power supply submachine (2), a hand-held sensor (3) and a removable induction head (4), and has the advantages of high speed, low energy consumption, no noise, no dust, no smoke, radiation prevention, discharge prevention, obsolete abrasiveness and sewage prevention, cleanness and safety, can removes the coasting difficult to be processed and on the surface of metal (in particular magnetic metal), can be widely suitable for coating removing operation of ships, storage grooves / cabinets / boxes, and various steel surfaces of coastwise and terrestrial oil conveying pipes.

Description

technical field

[0001] The invention belongs to the field of electromagnetic induction, in particular to an electromagnetic induction type metal surface coating removal method and equipment thereof. Background technique

[0002] The eddy current is that when the energized ferromagnetic metal block is close to the non-energized ferromagnetic metal block, a magnetic field in the opposite direction is generated on the surface of the non-energized ferromagnetic metal block, and this magnetic field generates a current that cuts the magnetic field lines. When the alternating current passes through the metal block, the current will concentrate on the surface of the metal block. This phenomenon is called skin effect, and the higher the frequency, the more obvious this phenomenon is. Due to the electrical resistance of metals, these eddy currents are converted into inductive heat energy, which has been widely used in industry to surface harden metals.
