摘要:
Thin metal strip is continuously cast by providing a first plate (100) and a second plate (101), each having a mold surface, and each having cooling means (114, 116) for controllably withdrawing heat from the respective plate. The mold surfaces contact molten metal which continuously solidifies against the surfaces, forming strips (118, 120). The strips are withdrawn continuously and merged together to form a single, composite strip. High frequency vibration can be applied to the plates (100, 101) in order to reduce sliding friction between each strip (118, 120) and its respective plate (100, 101).
摘要:
Metal strip is continuously cast using a primary solidification zone (245) in the form of a chamber for molten metal (224), the chamber being defined in part by an oscillating cooling wall (228) upon which solidification of the molten metal can take place, creating one face of the ultimate strip. Heat is withdrawn from the cooling wall (228) to promote solidification of the metal. A secondary solidification zone (247) adjoins the primary solidification zone and receives the solidified metal from the primary zone. The secondary zone is defined in part by a further cooling wall (268) facing oppositely from the oscillating cooling wall in the primary zone. Solidification of the molten metal takes place against the further cooling wall (268) in the second zone to create a second face of the metal strip. The metal in the secondary solidification zone is maintained against the further cooling wall to prevent liquid breakout. Heat is also withdrawn from the further cooling wall (268). The formed metal strip (273) is withdrawn from the primary zone (245) through the secondary zone (247).
摘要:
A method of and an apparatus for vertical, semi-continuous direct chill casting of light metal fabricating ingots of particularly, though not exclusively, lithium containing aluminium and magnesium alloys, through an open mould into a pit, comprising commencing the casting without a pool of water within the pit, supplying cooling water to the emergent ingot at a predetermined rate and continuously removing water from the pit as casting continues at a rate sufficient to ensure that no build up of a pool of water in the pit occurs, whereby the risk of violent and damaging explosion is further reduced.

摘要:
The invention relates to a processing system for processing a cast raw casting and to a casting cell and to a method for producing a cast component. The processing system has a spray system for cooling the raw casting, said spray system having at least one nozzle device for at least temporally, locally, or quantitatively variable application of a free-flowing medium to at least one section of the raw casting. The processing system also has a temperature measuring device for measuring the temperature on at least one section of the raw casting and a monitoring device for controlling and adjusting the nozzle device as a function of the measured temperature.
摘要:
An induction furnace comprising a upper furnace vessel; an induction coil positioned below the upper furnace vessel; and a melt-containing vessel positioned inside the induction coil and communicably connected to the upper furnace vessel, wherein the positioning of the melt-containing vessel inside the induction coil defines a gap between an outside surface of the melt-containing vessel and an inside surface of the induction coil. A system for direct-chill casting comprising at least one an induction furnace; at least one in-line filter operable to remove impurities in molten metal; at least one gas source coupled to a feed port associated with the gas; and at least one device for solidifying metal by casting. A method of cooling an induction furnace comprising introducing a gas into a gap between an induction coil and a melt-containing vessel positioned inside the induction coil; and circulating the gas through the gap.
