  • Patent number: 4614222
    Abstract: Apparatus and method for continuous casting of amorphous or polycrystalline metal strip from a melt. The molten metal is delivered from a reservoir (2) to a moving chill surface, preferably a cylindrical roll (1) through an orifice (3) in the reservoir (2). The gap between the reservoir (2) and the chill surface (1) is not fixed as in prior methods but is variable due to a resilient bias on the reservoir toward the chill surface. A pivot (10) and counterweight (11) are convenient apparatus for resiliently biasing the reservoir. The small portion of the reservoir (2) therefore rides lightly upon the molten metal film delivered to the chill surface or upon the solidified metal strip. The variable gap allows better control over the process and better quality surfaces on the metal strip.

  • Patent number: 4545422
    Abstract: A machine for casting battery grids continuously includes a rotary, cylindrical drum in the outer peripheral surface of which the battery grid cavity is machined in the form of a plurality of intersecting axially and circumferentially extending grooves. A shoe is arranged in close fitting, mating engagement with an arcuate segment of the peripheral surface of the drum. The shoe has a molten lead passageway therein which communicates with the peripheral surface of the drum by means of an orifice slot extending lengthwise of the shoe and across the drum. Molten lead under superatmospheric pressure is directed into a tube extending lengthwise within the lead passageway in the shoe and provided with a plurality of openings spaced lengthwise of the tube. The lead is discharged through these openings into the lead passageway, through the orifice slot and against the surface of the drum.

  • Patent number: 4544018
    Abstract: In order to be able to manipulate a feeding device with which molten steel is introduced into a twin-belt caster without ingress of air in preparation for the casting process and to carefully align the feeding device and the caster to the required extent, the feeding device includes a pouring body which is mounted in its own carriage so as to be rotatable about a horizontal pivot axis, and a separately movable tundish which is connected with the pouring body via a ball joint which forms the point of separation in that the ball socket of the ball joint and the ball pivot of the ball pivot are each respectively associated with either the tundish or the pouring body. The pouring body can be arrested in the manner of a rocker in different sloped positions and can be laterally displaced in a direction transverse to its longitudinal extent.

  • Patent number: 4506814
    Abstract: A revolving-ladle turret having a turret member supporting a platform which rotates around a vertical axis and which is furnished with ladle-carrying arms. The turret member is supported by a pair of articulated linkages similar to parallelograms of the double-handle type. The upper or bridge sides of the parallelograms are horizontal and rigidly supported by the structure carrying the machine. These parallelograms have their respective handles shaped at right angles and are linked to the turret member in positions which are symmetrical to it with respect to the axis of rotation of the platform and which effectively resist the torque which works on the turret due to the constant unevenness of the loads which act on the turret because of variations in the amounts of materials in the ladles.

  • Patent number: 4444341
    Abstract: A transport device for rapidly changing ladles for the continuous supply of metal melt to continuous casting plants by means of a reciprocating ladle bogie which is provided with means for receiving a sintle ladle. The bogie is moved between an operative position and an inoperative position, the bogie is positioned above a support from which an emptied casting ladle can be removed. In the operative position, the bogie is positioned above a casting station for supplying metal melt. The ladle bogie is open on the side nearest to the support and is rapidly driven back and forth between the inoperative and operative positions to provide a filled ladle from a crane and thereafter move an empty ladle to the support stand-by position for removal by the crane.

  • Patent number: 4434540
    Abstract: Techniques are disclosed for renovating sliding gate valve plates or for adapting conventional plates for use with problem-beset metals. Stationary plates (1) have their orifices (2) bored out to downwardly-tapering form and correspondingly tapered prefabricated refractory insert rings (3) are then cemented in place, the rings having axial depths equal to the plate thicknesses. An orificed plate (7) furnished with an integral depending nozzle (12) has its flow passage (13) bored out such that an upper bore portion extending through the plate (7) and part way along the nozzle (12) is transversely larger than the following downstream bore portion. A prefabricated refractory insert ring (9) is cemented into the upper bore portion, ring (9) being substantially as deep axially as the said bore portion. The downstream bore portion is lined with cementitious, metal-reinforced material (14).

  • Patent number: 4387761
    Abstract: Molten metal is introduced in a continuous-casting system downwardly into a mold through a nozzle opening downwardly into the mold at an axis to form in the mold a body of molten metal having an upper surface carrying impurities above the mouth of the mold. The body of molten metal is rotated about the axis in the mold. The nozzle is provided generally at the level of the upper surface of the body of molten metal with radially outwardly projecting vanes that prevent the body from rotating about the axis at the upper surface, thereby preventing inclusions from being sucked into the body of molten metal.

  • Patent number: 4359625
    Abstract: An immersion nozzle for continuous casting resistant to the corrosive action of the melt and the covering material in a mold is made of a refractory material comprising a mixture of electrically conductive graphite and/or silicon carbide, at least one member selected from the group consisting of alumina, zircon, zirconia, fused silica and a metallic silicon, and a binder. The nozzle is covered with a thermal insulating cover having a thickness of approximately 60 mm and made of fused silica containing fibers. The nozzle is preheated without moving it from its operating position by connecting a pair of electrical terminals to opposite ends thereof and passing electric current through the nozzle between the terminals for a period of time sufficient to raise the temperature of the nozzle sufficiently to prevent cracking, spalling, etc. during casting operation. After the preheating is completed the terminals may be removed from the nozzle.
