Abstract

Metal strip 3 may be cast directly from molten metal in an open tundish 2 onto a chill roll 1. Strip thickness is controlled by contouring the tundish lip 14 with an offset 10 near the casting wheel. This can be used remedially to offset the natural tendency for the strip to be thicker near the edges, which is undesirable for cold rolling, or it may be used creatively to produce contoured strip.
