ABSTRACT:
A multistage electromagnetic purification method of molten metal, which employs a multistage separator composed of two or more multichannel straight-pass separators bonded together with inorganic high-temperature adhesive. Each stage of the separators is set up in such a manner that the region of centerline of each channel in the former separators is occupied by the sidewall of the next separators at the corresponding position therein; while simultaneously the position in the next separators becomes a region close to sidewall. The multistage separator eliminates the “dead zone” of electromagnetic separation, realizes the transformation from “weak zone” to “strong zone” of electromagnetic separation, and significantly increases removal efficiency of inclusions in the melt with great volume under the effect of induced magnetic field.
