A production method for a medium- frequency furnace to smelt a zirconium ferrosilicon alloy comprises the following steps: adding zirconium mud into a sodium silicate solution and pressing into a zirconium mud block; taking ferrosilicon powder, fluorite powder and the zirconium mud block as raw materials, and throwing the raw materials into a crucible molten bath of the medium-frequency induction furnace; raising the temperature of the medium-frequency induction furnace to 1,400-1,550 DEG C to enable the materials to be completely molten; after the materials are completely molten down, blacking out and casting; cooling to the room temperature; discharging ingots; and finishing to obtain the zirconium ferrosilicon alloy. The production method has the advantages that the process is simple and reliable, the operation is convenient, zirconium mud which is low in cost is taken as the raw material, discarded zirconium resource is fully utilized, and the production method is economical and considerable, and energy-saving and environment-friendly.
