Open the CIPO recordAbstract From the Canadian patent
Metal strip may be cast directly from molten metal in an open tundish onto a chill roll. Strip thickness is controlled by contouring the tundish lip with an offset 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.
