摘要

The starting melt (1) used to produce the blank (4) is poured into a gap (2) between counter-rotating rollers (3). Casting process for preparing starting material for the production of hard magnets by powder metallurgy comprises casting a starting melt (1) based on rare earths, a transition metal and boron to form a blank. The starting melt (1) used to produce the blank (4) is poured into a gap (2) between counter-rotating rollers (3).
