APPARATUS AND METHOD FOR MAINTAINING CONSTANT MOLTEN METAL LEVEL IN METAL CASTING Apparatus and method for providing a constant level of molten metal to a mold in gas permeable shell mold casting. The apparatus includes a furnace for melting and holding metal to be cast. Structure is provided for locating a mold to be filled in casting relationship with the molten metal in the furnace and for causing molten metal to be drawn from the furnace into the mold. Structure responsive to the sensor is provided for tilting the furnace relative to the mold causing the level of the molten metal to remain constant relative to the mold as the mold is being filled. |
