Definitions
- the tapered section connects in the axial plane with the upper discharge openings with a continuous curvature.
- This curvature runs in said axial plane from the conduit to the very end of the upper channel, that is the discharge opening.
- the combination of the curvature and the side of the secondary divider facing the curvature define to a large extent the geometry of the upper channels.
- the resulting geometry is such that a complete filling of the upper channel is obtained along the whole length of the channel. This in turn results in a well defined yet into the fluid steel in the mould and therewith a good control over recirculation in the mould.
- the distribution zone 3 is shown in more detail wherein the distribution zone starts at horizontal line 15 with a first tapered part which continues to about the highest level of the discharge openings 9,10 in the upper channels 7,8. From that level a second tapered part starts which continues over part or the complete length of the lower channels 11,12. Preferably the second tapered part continues over only part of the length of the lower channels 11,12 wherein the larger part of the channels 11,12 downstream of the second tapered part have flat opposite sides. Both tapered parts run in a plane perpendicular to the plane of the drawing. The tapered parts are very effective in keeping the distribution zone and the channels well filled with fluid steel.
