Abstract: PURPOSE:To provide a rare earth metal cast magnet having high coercive force by casting molten alloy at the specific temp., rapidly cooling the molten alloy to peritectic reaction temp. zone at the specific velocity and slowly cooling the molten alloy in the specific temp. range under non-oxidizing atmosphere at the specific velocity. CONSTITUTION:The molten alloy M in a tundish 1 is continuously cast through twin belt type continuous casting machine 2, temp. holding cover 3, cutting machine 4 and temp. holding furnace 5. Then, in the molten alloy M, at least the rare earth element, transition element and B are contained as essential components. The casting temp. of the molten alloy M is made to 1200-1700 deg.C. After casting, this is rapidly cooled to the peritectic reaction temp. zone at >=5 deg.C/sec. After that, this is slowly cooled from 700 deg.C to 350 deg.C under the non- oxidizing atmosphere at <5 deg.C/sec to obtain columnar crystal orientated toward the slab thickness. By this method, the cast slab having excellent magnetic characteristic of high orientation without any casting defect can be produced with the continuous casting.
