Abstract: 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 may force 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. Inert gas sensors may detect loss of inert gas from the interior chamber.

Abstract: For the continuous casting of silicon, an electrically conductive bottomless crucible is circumferentially divided by axial slits and is positioned within an electrical induction coil. The slits form circumferential gaps of between 0.3 mm and 1.0 mm and the inner wall of the crucible is inclined by between 0.4.degree. and 2.0.degree., so that the crucible expands in the downstream direction of movement of the silicon. In order to reduce the temperature gradient of the solidified silicon to between 20.degree. C./cm and 100.degree. C./cm, an additional heating element is disposed downstream of the boundary surface between the molten and solidified silicon. The crucible may be cooled by forming the crucible as a double walled cylinder and flowing a coolant therethrough.

Abstract: A method and apparatus is disclosed for casting conductive and semiconduce materials. The apparatus includes a plurality of conductive members arranged to define a container-like area having a desired cross-sectional shape. A portion or all of the conductive or semiconductive material which is to be cast is introduced into the container-like area. A means is provided for inducing the flow of an electrical current in each of the conductive members, which currents act collectively to induce a current flow in the material. The induced current flow through the conductive members is in a direction substantially opposite to the induced current flow in the material so that the material is repelled from the conductive members during the casting process.
