Abstract

PURPOSE: To maintain low coercive force and high squareness by allowying a molten alloy consisting essentially of Fe, Ni, Si and B in specified atomic ratio to closely contact to the circumference of a cooling roll over a specified length or more and forcing the resulting sheet to be peeled off.
CONSTITUTION: The alloy has a composition consisting of, by atom, 4W10% Fe, <40% Ni, <20% Si, 5W20% B (Si+B=20W28%) and the balance Co. Such starting material metals are charged into quartz pipe 1 and melted by heating with heating furnace 4. when nozzle 2 is lowered with core piston 8 to a position opposite to outer surface part 6 of rotating cooling roll 5, a gas pressure is applied to molten metal 3. Metal 3 is spouted toward part 6 and closely contacts to roll 5 over ≥30cm length of the roll surface circumference. At the same time, metal 3 is rapidly cooled and converted into amorphous alloy sheet 7 by instantaneous solidification. Sheet 7 is then forced to be peeled off the roll surface in the arrow direction.
