Abstract
A process for continuously casting steel wherein liquid steel is teemed from a ladle through a shroud into the pour box section of a tundish and poured from the tundish through one or more outlets remote from the pour box, and wherein the surface of the steel in the tundish is covered with a first flux in the area of the pour box and with a second flux in the remaining areas of the tundish. The flux used in the pour box area has a higher melting temperature than the flux used in the remaining areas. Preferably all fluxes used are basic fluxes containing CaO and Al.sub.2 O.sub.3.
