Estimating the term…
A device and a method for casting of strips from a metal melt includes the use of two casting rollers, which delimit between them a casting gap at their longitudinal sides, and two side plates, which, arranged opposite one another, are held in contact at face sides of the casting rollers, allocated to narrow sides in each case of the casting gap. With the device and method, metallic strips can be reliably produced which have high dimensional stability even in the area of their strip edges, in that the risk of a gathering of solidified melt at the side plates in casting operation is reduced to a minimum. This is achieved by providing at least one heating device for the heating of the casting rollers in at least those sections of their face sides at which the side plate, allocated to the face side in each case, is in contact.
Device for the casting of strips from a metal melt with two counter-rotating casting rollers when in casting operation, which delimit between the two counter-rotating casting rollers a casting gap on their longitudinal sides, and with two side plates, which are held opposite one another arranged in contact with face sides of the two-counter-rotating casting rollers allocated to in each case narrow sides of the casting gap, in order to seal the casting gap at the narrow side in each case, wherein at least one heating device is provided for heating the casting rollers in at least those sections of their face sides at which an allocated side plate in each case is in contact.
Method for casting of strip from a metal melt, in which the metal melt is cast into a casting gap, longitudinal sides of the casting gap are delimited by two counter-rotating casting rollers and narrow sides of the casting gap are sealed by side plates being pressed in each case against two face sides of the two counter-rotating casting rollers allocated to individual narrow sides, wherein the two face sides of the casting rollers at least in the area in which they are adjacent to one of the side plates in each case, are heated, limited locally, to a temperature which lies above the surface temperature of the casting rollers outside these areas.
