Abstract (en)
[origin: US6260740B1] The invention relates to a process and a device for controlling the flow dispersion of a molten metal, in particular steel, which is conveyed from a melt container via a first immersion outlet part which has a polygonal, oval or circular cross-section, and an intermediate member through the second immersion outlet part which has an elongate cross-section, and flows into a stationary mold to produce slabs. The process is characterized by the following steps: (a) the central volume flow is reduced in the intake region of the second outlet part; (b) at the same time the angle of expansion (delta) of the fluid jet is increased to such an extent that the return flow in the lateral region of the intermediate member and the second immersion outlet part is substantially stopped; and (c) when the melt leaves the second immersion outlet part, it flows at a velocity profile with velocity vectors which are smaller in the opening center than the regions of the small faces. The device is characterized in that the region of the central axis (I) of the immersion outlet, the intermediate member (31) and/or the intake (22) of the second immersion outlet part (21) is equipped in such a a manner that the main flow of melt (S) leaving the first immersion outlet part is throttled.
