| An integral melter and pump assembly or system, and a method of making the same, is disclosed wherein the pump assembly comprises a melter housing having a melter container defined within the melter housing. A pump mounting plate is integrally mounted within a side wall portion of the melter container and an output dispensing supply pump is mounted directly upon an external surface portion of the pump mounting plate in a surface-to-surface manner such that heat generated internally within the melter container is effectively transferred by conduction from the melter container and through the pump mounting plate such that the temperature level of the output pump is elevated to, and maintained at, a predeterminedly desired level even when the pump, is not disposed in its output dispensing mode. In addition, since the output dispensing or material supply pump is disposed externally of the melter container and the melter housing, the output dispensing or material supply pump is easily and readily accessible in case maintenance becomes necessary. Optionally, an oil jacket or chamber can surround the melter container so as to more evenly or consistently provide heating of the melter container. | ||||||

| An electrically energized aluminum melting furnace comprises a vessel for supporting molten aluminum and a roof and upper wall structure cooperating with side walls of the vessel to define a heating chamber above the molten aluminum. A plurality of unshielded resistance heating elements are supported by the roof and upper wall structure above the molten aluminum. The molten aluminum has access through a submerged opening to a charging well to which unmelted aluminum is periodically charged without danger that molten aluminum will splash upon the heating elements. Heat conducted from the heating chamber through the body of molten aluminum residing in the vessel is utilized to melt in the charging well the aluminum charged thereto. The melted aluminum in the charging well is permitted to flow through the heating chamber and through a submerged opening to a hot metal well from which hot metal may be withdrawn by any of numerous techniques. The heating chamber is so arranged that an oxide skin is preserved at the surface of the molten aluminum residing within the heating chamber, the oxide skin effecting an efficient transfer of radiant energy received from the resistance heating elements to the molten aluminum. The aforementioned roof and upper wall structure is rested upon furnace walls so as to allow a vertical growth of the furnace walls. | ||||||
| 51 | Method and apparatus for heating pieces of steel scrap | US43238774 | 1974-01-10 | US3880649A | 1975-04-29 | BLOOM WILLIAM M |
| Pieces of steel scrap are charged into a ladle by a magnet on a crane so that the central part of the charge is substantially denser than the peripheral part. A cover having a plurality of natural gas-oxygen burners mounted around its periphery is then placed on top of the ladle to obtain a substantially gas tight container except for a flue opening and some small openings due to a non-tight fit between ladle and cover adjacent the top. The burners direct their flames downwardly parallel to the sidewall of the ladle and the combustion gases are discharged through the flue opening. The flames are reducing in nature and the container is under a positive pressure. The heating is continued until the scrap is at a temperature of at least approximately 1,500*F and preferably approaching the melting point of the scrap. Molten iron in substantially greater weight than the scrap and having a substantially higher carbon content is then poured into the ladle so that the majority of the scrap is melted. The mixture is then easily poured from the ladle into the oxygen converter.

| PROBLEM TO BE SOLVED: To enable to quick melt while preventing impurity from intruding at a low cost by selectively and sequentially executing induction-heating to plural solid alloy charging constituted elements separated in a refractory melting vessel. SOLUTION: In a melting example of Ti-6Al-4V alloy, after introducing a high m.p. lower part charging material constituted element C1 composed of Ti (slender small piece) spotted with a fixed quantity of V (black block) into the refractory melting vessel 54, a low m.p. upper part charging material constituted element C2 composed of a solid Al piece (round grain) and Ti piece, is introduced into 1/3 of the upper end of the vessel 54 and after selectively induction-preheating with an induction coil 68a, the constituted elements C 1, C 2 are melted with an induction coil 68. The upper constituted element C 2 is made to flow toward the bottom part of the vessel 54 and the melting of the upper end or the lower end of the constituted elements C 1, C 2 is started and at the same time, the molten alloy is held to separate from the side wall of the vessel 54 with high induction power level and restrain harmful reaction with the refractory. Successively, a mold vessel 20 is descended and the molten alloy is sucked from a filling tube 23 and filled into a mold 22. COPYRIGHT: (C)1999,JPO | ||||||
