MULTIFUNCTIONAL SYSTEM FOR DEMAGNETIZATION OF FERROMAGNETIC ARTICLES Russian patent published in 1998 - IPC

FIELD: demagnetization of ships, vehicles, turbines, diesel engines and other equipment. SUBSTANCE: device has ho cable of four rectilinear working conductors which are designed as buses mounted in pairs on each side along length of treated article. Buses on one side are spaced by distance which depends on height of article. Unipolar generator is used for power supply. Device is organized in modules, it has power supply unit and side working units, load-bearing working buses. Channel of location of units provides possibility to process articles of various width, height and length. System may be delivered by ground or if housings of units are water-tight, by water in order to achieve process floating articles. Device has indicators which read magnetic field intensity in cross section along length of article. Device provides possibility for processing articles by common vertical, inclined and horizontal fields (rotating field), local field of region where ferromagnetic object is located as well as by longitudinal field. EFFECT: increased functional capabilities, facilitated use, increased efficiency. 12 cl, 20 dwg
