MULTI-FUNCTIONAL SYSTEM FOR DEMAGNETISING FERRO-MAGNETIC OBJECTS

摘要

The present invention relates to techniques for demagnetising objects in a fusion cake, objects used in vehicle construction, turbines, diesel engines as well as other equipment. The purpose of this invention is to provide a standardised, mobile and cost-effective system. The system of the present invention comprises four rectilinear working conductors in the shape of busbars which are assembled by pairs on each lateral side of the object to be treated and on the whole length thereof, wherein said busbars are arranged one above the other at a distance determined by the object height. This method uses as a power supply a unipolar generator. This system also comprises power supply modules as well as lateral working modules supporting the working busbars. The transformation of these modules allows for the processing of objects having various widths, heights and lengths. This system can be transported on the ground and, when the module bodies are made water-tight, it can be used for processing floating objects and can be transported by sea. The system of the present invention further comprises sensors for measuring the magnetic field in the transverse section of the object on the whole length thereof. This system may be used for processing an object by applying a common vertical field, an inclined field and a horizontal field, by applying a local field in the region of the concentrated ferro-magnetic mass or by applying a longitudinal field.
