ABSTRACT:
The tube for introducing a metal melt into a continuous casting mold having broad side walls and narrow side or end walls includes a tube section provided with lateral openings for the metal melt whose central axes substantially are oriented towards the narrow sides of the strand being formed in the mold and a bottom portion provided with a bottom opening for the metal melt. In order to ensure, at high casting rates, both a slight vertical depth of penetration of the metal melt supplied through the casting tube into a liquid core of the strand and a slight whirl formation on the meniscus, the bottom portion includes at least two bottom openings oriented obliquely towards the narrow sides of the strand so as to form at least two casting jets whose flow directions cross each other in a viewing direction extending perpendicular to the wide sides of the strand.
