A method and apparatus for preheating and distributing magnesium ingots used in magnesium die casting wherein the heating efficiency is improved thus reducing the energy required to heat the ingots to a temperature varying between 150°C - 350°C prior to charging into a molten magnesium bath. A housing comprising a ceiling, a floor, side walls extending from the floor to the ceiling for defining a chamber which is divided into at least a storage area and a heating area, and means for moving the ingots from one side to another as well as out to the molten magnesium bath are provided. The apparatus of the invention is adapted to be securely positioned directly atop of a melting furnace whereby the heat generated by said furnace is used to preheat the ingots located within the apparatus prior to charging.
