| 20090159236 | APPARATUS FOR SHAPING MELTS COMPRISING INORGANIC OXIDES OR MINERALS WITH AN IMPROVED HEATING DEVICE - Fibers, pipes, rods, strips or profiles made of high-melting inorganic oxides or minerals are used in great quantities, for example for reinforcing plastics, ceramics and metals. In order to produce said products, use is made of apparatuses comprising a melt container with an individual orifice, or orifice plate with a multiplicity of orifices, arranged in the base of the melt container. The melt in the melt container has to be kept at as homogeneous as possible an operating temperature above the individual orifice or orifice plate. For this purpose, the melt container is usually heated by a direct through flow of current. This results in high radiation losses to the surroundings and to a correspondingly high need for electric energy. It is proposed, for the heating of the melt, to arrange one or more pipes in the melt container, the pipes having at least one connection to the outside through the container casing, and electric heating elements being inserted into the pipes. This type of heating results in a homogeneous temperature distribution of the melt above the individual orifice or the orifice plate and permits an energy saving of more than 50%. | 06-25-2009 |

| 20080251230 | Strip Casting of Immiscible Metals - The present invention discloses a method of strip casting an aluminum alloy from immiscible liquids that yields a highly uniform structure of fine second phase particles.

The method is advantageous in that it is possible to produce steel adapted for low-temperature impact absorption, and productivity is improved due to the increase of the number of consecutive heats of continuous casting. | 03-29-2012 |
| 20120199307 | CONTINUOUS CASTING SEALING METHOD - A casting furnace for manufacturing a metal casting comprises an interior chamber and a secondary chamber through which the metal casting passes from the interior chamber into external atmosphere. A seal along the secondary chamber surrounds and seals against the metal casting to separate the interior chamber from the external atmosphere in a manner which allows for an extended period of continuous casting. A force producing mechanism typically forces the seal against the metal casting. Multiple seals may be used sequentially to increase the duration of the sealing capability and the continuous casting process. | 08-09-2012 |
