摘要:
The invention relates to a method for producing ingot molds (1) for pig casting installations used for producing pigs. According to the invention, mill bars (2) comprised of copper are used as starting material. Said mill bars are, in particular, comprised of a copper alloy which is suited for cold forming and which has a comparatively high degree of elongation. The mill bars are formed into the shape of ingot molds by means of a conversion process in which the mill bars are formed under tensile conditions or under a combination of tensile and compressive conditions. The invention also relates to an appropriate device for producing the ingot molds for pig casting installations.

The invention relates to a pig casting machine comprising at least one endless conveyor belt (2), on which pig casting molds (3) are fixed, for conveying pig casting molds from a casting station (4) to a pig removal station and vice versa, wherein each pig casting mold is filled with molten metal as it passes through the casting station with the mold cavity facing upwards, in addition to a device for cooling the pig casting molds before, during and/or after casting, wherein the pig casting molds are embodied having a thin wall. According to the invention, in order to increase output and to be able to cast heavy metals in such a pig casting machine, the pig casting molds (3, 112, 207) are designed to receive molten metal at a melting temperature above 1,000 °C.

Masselstapel, beispielsweise aus Aluminiummasseln, werden durch Schichten von Einzelmasseln erzeugt. Derartige Masselstapel sind nicht transportsicher. Zur Vermeidung des Herausrutschens und Herausfallens einzelner Masseln aus dem Masselstapel wird ein metallisches Gewebe, metallisches Gewirke, Maschenwerk aus Metalldraht oder Streckmetall zumindest an den Seitenflächen oder an Seiten- und Deckflächen des Masselstapels angebracht und/oder der Masselstapel enthält zwischen wenigstens zwei Lagen von Masseln wenigstens eine Zwischenlage aus metallischem flächenhaften Material.
摘要:
A device for automatic regulation of billet mould filling in a chain layout, with a rod (11) that vertically approaches the billet moulds (1), without making contact with the liquid level and provides a signal of the approach of this level, which is transmitted to a control box. This signal can regulate the speed of the chain, the volume of filling flow for each billet mould or the approach volume of the liquid metal, etc., depending on the cases.

The invention relates to an ingot mould (1) for metals, which is intended for the production of an ingot through the cooling and solidification of a liquid metal mass. The inventive mould consists of a wall (2) which defines a base (4) and an inner surface (5) comprising one part S, known as the cooling surface, which can discharge all or part of the heat energy released by the metal mass during the cooling and solidification thereof. The invention is characterised in that the cooling surface S comprises at least one flat surface element Si which forms all or part of the base (4) of the ingot mould (1). The invention is also characterised in that it comprises at least one point C on a plane Pi which is tangential to each surface element Si, such that all of the segments of the straight line D connecting every point R of the cooling surface S to point C are only located inside the mould (1). The invention is further characterised in that the total area of surface elements Si is at least equal to 10 % of the surface S. The inventive ingot mould can be used to accelerate the production of ingots.

The invention relates to a method and apparatus for producing standard-weight metal object, alloyed with at least one alloy ingredient, by means of casting. According to the invention, the main metal and alloy ingredient flows are conducted so, that the alloy ingredient is fed into the molten main metal flow in between the smelting furnace (1), used for smelting the main metal, and the casting mold (9).

The device is comprised of an ingot mould (1), made of copper, formed by two half chills (2) of which at least one comprises a plurality of cavities (10) of the ingots to be cast, which cavities communicate through channels (11, 12) and open at the upper part on to a pig sow (18); cooling means (5) by heat conveyor fluid for each half chill (2); means (9) for contacting and sealing both half chills; means for taking away both half chills from each other; means (7, 8) for guiding the take-away motions and for sealing the half chills.
摘要:
A stack of ingots is built up by assembling the ingots (2) into layers (12) and then lifting each successive layer into engagement with the bottom of a stack (13) formed by previously lifted layers. The stack rests on a support (5) and is rotated between successive layers so that the ingots in a layer are at right angles to those in odjoining layers. This provides an increased rate of stacking compared with conventional ingot stackers.
