摘要： PROBLEM TO BE SOLVED: To enlarge an adjustable range of quenching speed in a melt spinning method. SOLUTION: A manufacturing method of a rare earth quenching magnet comprises a process for preparing melt of alloy having composition which is expressed by a composition formula T 100-x-y-n Q x R y M n , and whose composition ratios (x), (y) and (n) satisfy 4≤x≤30 atom%, 2≤y≤13 atom% and 0≤n≤10 atom%; and a quenching process for cooling melt by the melt spinning method and forming quenching solidification alloy. The quenching process comprises a process for cooling melt by bringing melt into contact with a surface of a cooling roll while the cooling roll is rotated, a process for supplying a cooing medium into the rotating cooling roll and extracting heat of the cooling roll, and a process for controlling rotation peripheral velocity of the cooling roll and a heat extraction amount by the cooling medium.
