An immersed casting tube for introducing a metal melt into a continuous casting mold having broad side walls and narrow side walls includes a tube section provided with lateral opening for the metal melt whose central axes substantially are oriented towards the narrow sides of the strand, 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 the liquid core of the strand and a slight whirl formation on the meniscus, the bottom portion includes at least two bottom opening 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 perpendicular to the broad sides of the strand.
