description The invention relates to directional aluminum-nickel-cobalt magnetic steel and a preparation method thereof, and the preparation method comprises the following steps: starting a temperature adjusting medium, and adjusting the temperature of a directional crystallizer panel to 10-25 DEG C by using the temperature adjusting medium; the smelted molten steel is cast into a preheated sand mold, heat preservation is conducted after casting is completed, the temperature adjusting medium is closed within 5 min, heat preservation continues to be conducted for 20-35 min, and then a formed hot blank is taken out and subjected to annealing treatment; and then the annealed blank is subjected to rough machining, heat treatment, magnetizing treatment and tempering treatment in sequence, and the oriented aluminum-nickel-cobalt magnetic steel is obtained. According to the method, the heat exchange amount and the heat exchange rate in the cooling process are effectively adjusted by controlling the directional solidification co
