| 20100044001 | METHOD AND APPARATUS FOR CASTING NF METAL BATHS, PARTICULARLY COPPER OR COPPER ALLOYS - A method and apparatus for casting NF metal baths, particularly copper or copper alloys, to produce flat products at least 20 mm thick, ensure melt introduction into a pool while preventing gas pockets or impurities flushing into the melt of a casting mould. The melt continuously flows along a flow-off element from a tundish to a bath level of the mould, at a casting angle of up to 15° and a constant or decreasing rate, and is conducted below a pool surface of the mould without influencing flow rate. Vortexes generated by melt hitting the bath surface are prevented from extending within the mould by a cover surrounding a top surface of the flow-off element. Gaseous components produced when the melt flows, escape via a free space above the flow. Gravity determines a flow rate of the free melt flowing from tundish to molten bath of a revolving strip-casting mould. | 02-25-2010 |
