Metal casting
Реферат: 1339301 Casting processes F KOCKS 19 April 1971 [2 March 1970] 22221/71 Heading B3F In a method in which ingots are cast and subsequently processed one after the other, they are cast in a chronological sequence at time intervals corresponding to the cycle time of the processing step. The melt is supplied from a smelting furnace to a heated vessel from which it is poured into the moulds at predetermined intervals of time. The said vessel holds enough metal to cast a plurality of ingots and is refilled from the furnace before it has been completely emptied, the heating being interrupted before the refilling so as to allow the new batch of metal to cool to the pouring temperature. Two or more smelting furnaces may be provided for each vessel if the time required for charging the furnace is longer than the sum of the casting intervals in each casting cycle, i.e. the time interval between filling of the said vessel and the removal of the last ingot portion therefrom. Conversely, two or more vessels may be refilled from the same furnace if the charge time is substantially less than the length of a casting cycle. An example describes the production of ingots at 15 minute intervals using a vessel having a capacity equivalent to five ingots.
