A method for effectively reducing a chromium element in a metallic beryllium raw material belongs to the field of metal material purification methods. The method comprises the following steps: (1) loading beryllium metal with high chromium content into an intermediate frequency induction furnace; (2) closing the furnace door to perform vacuum pumping, power supplying, and induction melting, and pouring the solution into a graphite ingot mold to cool after melting is finished; (3) carrying out ingot scalping, chip making and powder crushing; and (4) pickling and drying crushed beryllium particles. The invention has the remarkable effect that the Cr element in the beryllium raw material is effectively removed by control of the melting and solidification process and the pickling process of the beryllium material, and the Cr element in the beryllium material product is far lower than the military standard, and the method has the characteristics of simple process, small investment, strong operability and high production efficiency.
