Methods to Lower the Production Costs of Magnets and Magnetic Materials,d for inserting and removing the tubes from the melt. The lower ends of the tubes are positioned well below the upper surface of the melt where the solid impurities collect. The molten alloy rises in the mold tubes to the selected level for forming the rods.
