Cerium-containing anisotropic bonded magnetic powder and preparation method of magnet

The invention provides a preparation method of cerium-containing anisotropic bonded magnetic powder and a magnet. The preparation method comprises the following steps: S1, preparing raw materials; s2, smelting: smelting the prepared raw materials to generate a thin-plate-shaped rare earth alloy steel ingot or a flaky rare earth alloy quick-setting casting sheet; s3, HDDR treatment: carrying out HDDR treatment on the rare earth alloy steel ingot or the rare earth alloy rapid-hardening casting sheet to prepare (Ce, Re)-Fe-B-M anisotropic magnetic powder; s4, magnetic field orientation compression molding: mixing the (Ce, Re)-Fe-B-M anisotropic magnetic powder with binder resin to generate magnetic powder granules; the magnetic powder granules are pressed, demagnetized and cured in a mold to obtain the anisotropic (Ce, Re)-Fe-B-M bonded magnet. According to the preparation method of the cerium-containing anisotropic bonded magnetic powder and the magnet, the raw material cost of the formula is reduced; the ceriu
