    摘要： A float-distributor for direct chill casting of metals, particularly, aluminum and aluminum base alloys. The floatdistributor comprises a float adapted to float on the surface of the molten metal in the mold. The float is adapted to fit about a feed nozzle which supplies the molten metal to the mold. Means for distributing the molten metal about the periphery of the mold is provided and is supported beneath the float. The distributing means generally comprises a cone shaped distributor which is supported in axial alignment with the feed nozzle. The apex angle of the distributor is generally kept between about 60* and 150*. The float may include means for increasing its buoyancy as the flow rate of molten metal issuing from the feed nozzle increases. The float may also contain means for preventing capillary flow of molten metal between the float and the feed nozzle.

    摘要： A molten metal level control includes a breakable tube for automatically feeding molten metal from a source to the mold, the tube having a first portion attached to the source and a second portion depending from the first portion. The control also includes float means mechanically coupled to said second tube portion for automatically controlling the rate at which the molten metal enters the mold from the breakable feed tube, and metering rod means positioned for coaction with said first portion of the breakable feed tube to provide uninterrupted regulation of the rate of flow of molten metal therethrough from the source and into the mold during emergencies when the second portion of the feed tube is broken from its first portion to eliminate automatic level control.

    摘要： Submerged nozzle (1) through which molten steel can be poured from a tundish into a mould, said nozzle comprising: a substantially tubular body (2), extending from a first end (3) to a second end (4); a passageway (5), extending through the tubular body (2) along a longitudinal axis (A) from the first end (3) towards the second end (4); at least one inlet port (6), opening into the passageway (5) at said first end (3); a plurality of outlet ports (8), opening into the passageway (5) in a region (7) adjacent to the second end (4); and at least one rotatable insert (10); whereas the submerged nozzle (1) with the at least one rotatable insert (10) is configured that a molten metal entering the submerged nozzle (1) at the at least one inlet port (6) flows through the passageway (5) and around the rotatable insert (10) and exits the submerged entry nozzle (1) via the plurality of outlet ports (8), such that a rotation of the rotatable insert (10) is driven by the stream of molten metal.

    摘要： A double-acting switch valve includes a mounting bracket and two mutually backup sealing assemblies disposed on the mounting bracket, each of the two sealing assemblies including a carbon rod and a carbon rod moving assembly, the carbon rod moving assembly being configured to translate, and elevate or lower the carbon rod so as to block or open a metal liquid channel between two metal liquid furnaces. Two sealing assemblies which are mutually replaceable, where when the carbon rod on one of the sealing assemblies is worn down, the other sealing assembly may take its place to block the metal liquid outlet again via the carbon rod; and then the worn-down carbon rod is renewed. This design eliminates the time taken for replacing the carbon rod and can reduce the amount of the metal liquid discharged via the metal liquid outlet during replacement of the carbon rod.

    摘要： A distribution device for use with a vertical casting system includes a body made of a refractory material, which includes a base and a peripheral wall. The base and the peripheral wall enclose a trough for containing and distributing liquid metal. A thermally insulating layer is located in a recess beneath the base. The refractory material of the body has a first thermal conductivity and the thermally insulating layer is made of a material having a second thermal conductivity that is less than the first thermal conductivity.
