METHOD OF INDUCTION HEATING OF COMPACTED BLANKS FROM POWDER MATERIALS Russian patent published in 2001 - IPC

Abstract RU 2165826 C1

FIELD: powder metallurgy; applicable in heating of blanks in sintering and subsequent hot molding. SUBSTANCE: method includes heating of blank with the help of inductor. In so doing, during heating, difference of temperatures between external surface and central part of blanks is preset at value not exceeding that determined by formula given in the invention description. EFFECT: preserved integrity of cylindrical blanks from powder materials due to excluded occurrence of axial stretching stresses. 1 ex
