description The invention discloses a medium-high manganese steel dendritic crystal spacing prediction method based on a directional solidification experiment. The method comprises the following steps: (1) processing medium-high manganese steel into a sample; (2) carrying out a directional solidification experiment on the sample; the directional solidification experiment comprises a heating process, a cooling process and a rapid cooling process; (3) measuring the primary dendritic crystal spacing and/or the secondary dendritic crystal spacing of the medium-high manganese steel after the directional solidification experiment; and (4) obtaining the primary dendritic crystal spacing and/or the secondary dendritic crystal spacing of the medium-high manganese steel at a plurality of different drawing speeds according to the measurement in the steps (1)-(3), and obtaining a relational expression between the drawing speed of the medium-high manganese steel and the primary dendritic crystal spacing and/or the secondary dendritic
