摘要:
Die Erfindung betrifft eine Vorrichtung zum Stranngießen, insbesondere von Edelmetallen und/oder Edelmetallegierungen und/oder NE-Metallen, mit einer Schmelzkammer, einer Energiequelle zum Aufschmelzen des Materials, mit einer Stranggußkokille und mit einer unterhalb der Stranggußkokille angeordneten Abzugsvorrichtung. Diese Vorrichtung zeichnet sich dadurch aus, daß sie mehrere Schmelzkammern (6) mit der jeweils zu einer Schmelzkammer dazugehörigen Stranggußkokille (3) aufweist, die auf einem gemeinsamen, verschwenkbaren Träger (3) angeordnet sind.
摘要:
Bei einem Verfahren zum Erzeugen von Walzvormaterial durch Stranggießen für Langprodukte aus Metall, insbesondere aus Stahl, wie z.B. Profilstäben, Profilträgern, Draht und Schienen, erfolgt nach dem Gießprozeß ein Umformen des runden Gußmaterials auf Anstichabmessungen eines Längswalzwerkes bzw. auf Schmiedeabmessungen. Da Walzvormaterial hoher Qualität und Güte ohne Kosteneinsparung nur im Standguß erzeugt werden kann, wird vorgeschlagen, um hohe Materialqualität und Materialanalyse zu erzielen, daß die Metallschmelze zwischen Vorschaltgefäß und Stranggießkokille unter Luftabschluß vergossen wird, daß das Gußmaterial in einer Einheits-Stranggießkokille mit einem rundähnlichen Einheits-Querschnitt hergestellt wird und daß das Verhältnis Volumen/Oberfläche des Gußmaterialabschnitts mindestens 40 : 1 mm3/mm2, maximal 150 : 1 mm3/mm2 beträgt.

摘要:
The continuous casting apparatus is provided with: a bottomless mold with a circular cross-sectional shape into which molten metal of melted titanium or titanium alloy is poured from the upper opening and is extracted downward as the molten metal is solidified; and plasma torches, which are disposed above the molten metal in the mold and are for generating plasma arcs for heating the molten metal. Ingots are continuously cast by moving the multiple plasma torches, which are disposed above the molten metal in the mold, in the horizontal direction above the surface of the molten metal along paths that maintain a distance such that the torches do not interfere with each other.
摘要:
Metal sheets (13) are produced from thin-gauge billet-type sections (8) consisting of magnesium or magnesium alloys, by means of an extrusion facility (1). The open or closed extrusion section (8) exiting the extrusion die (6-7) of an extruder (1) is formed into a uniform sheet (13) and subsequently subjected to a defined forming process by drawing. The facility for carrying out the method consists substantially of an extruder (1) with a die that produces the extruded section and of a forming unit (5) adjoining the die. The forming unit (5) is composed of a separation unit (2), a bending unit (3) and an unfurling unit (4).
摘要:
The present invention relates to a energy- saving steel production apparatus, including an hot-rolling production line and a continuous casting equipment (5) for producing semi-manufactured products or billets, said production line and said equipment facing one each other and being connected through fast transport means (7) moving said billets. The invention also relates to a method for processing energy- saving steel, comprising the following steps: a. taking the steel to a casting temperature; b. casting said steel in suitable moulds for obtaining a semi-manufactured product; c. transferring directly said casted semi-manufactured product towards a rolling mill through fast transport means; d. taking said semi-manufactured product to a value of temperature corresponding to a maximum value of plasticity; e. subjecting said semi-manufactured product to a rolling process.
摘要:
In order to be able to carry out a multiplicity of continously recurring activities at a continuous casting plant in a precise and automated manner in a continuous casting plant having at least one multifunction robot for implementing a plurality of different process-controlled or automated interventions at the continuous casting plant without the accessibility of the casting plant for the operating personnel being impaired or without an additional risk of accident being produced due to the multifunction robot, at least one working region is established at the continuous casting plant and at least one multifunction robot is assigned to each working region. The multifunction robot is arranged on a swivel arm of a rotary column fastened to the pouring platform of the continuous casting plant and can be swivelled with the swivel arm between a retraction position and a working position.
