IPC: B22D11/06
Filed: 2001-09-18
Abstract: The reliable sealing of a gap ( 10 ), between a roller front face ( 7 ) and a side seal ( 3 ) on a roller-strip-casting machine is achieved by the generation of an electrical eddy field in the region of the gap ( 10 ), such as to produce a local gradient field ( 13 ). The eddy currents generated in the metal melt for casting prevent the ingress of the metal into the gap ( 10 ) or eject the metal from the gap ( 10 ). The risk of escape of liquid metal is essentially eliminated and the formation of ridges on the narrow edge of the metal strip avoided.
