A method of continuously casting steel in which a melt from a movable distributor is introduced through a movable immersion nozzle having an outer lower edge into a mold of rectangular cross-section having an upper edge. The mold has a cross-sectional width of between about 40 and about 100 mm and a cross-sectional length of between about 200 and about 2000 mm. The casting is withdrawn from the mold. The melt introduced into the mold defines a bath of steel therein. The method involves the first step of controlling the start of the casting process in connection with the withdrawal of the casting by starting the withdrawal of the casting upon reaching a desired height of the surface of the bath of the steel in the mold, and driving the casting from the mold at a desired casting removal speed via a control element in a predetermined manner. The position of the bath level as it ascends in the mold during the continuous casting is measured. The position of the immersion nozzle in relation to the ascending bath level is adjusted from a first position to a desired operating position by changing the position of the distributor. The desired operating position of the immersion nozzle with respect to the upper edge of the mold is determined as a function of the temperature of the steel melt, the quality of the steel, the K-value of the solidification of the casting, the speed of withdrawal of the casting and the bath level, so as to establish, during the casting, a spacing of the outer lower edge of the immersion nozzle between a solidification front of the casting and the bath level.
