METHOD AND DEVICE FOR MANUFACTURING SOFT MAGNETIC METAL POWDER, SOFT MAGNETIC METAL POWDER, COMPACTED BODY, AND MANUFACTURE OF COMPACTED BODY

摘要

PROBLEM TO BE SOLVED: To surely manufacture a soft magnetic metal powder of a compacted body forming material in obtaining the body capable of providing the high saturation magnetic flux density and the high permeability at the pane time. ;SOLUTION: In a method in which a molten metal 59 flows in a small stream, and is divided into small pieces by ejecting the gas jet 73 thereagainst, and, immediately thereafter, plunged into a cooling liquid layer 66 turned in a cylindrical manner, the initial speed of the flow of the cooling liquid layer 66, the number of revolution during the turn, the height of the converging position P, the angle of incidence of the gas jet 73 in the cooling liquid layer 66, the pressure of the gas jet 73, etc., which are obtained in various experiments, are limited to specified ranges.;COPYRIGHT: (C)2001,JPO
