Abstract
Casting molten metal using a segmented roll for casting continuous metal strip. A strip caster (10) for producing a continuous strip (18) includes a tundish for containing a melt and a pair of horizontally disposed water cooled composite casting rolls (84). The casting rolls are juxtaposed relative to one another for forming a pouring basin (16) for receiving molten metal. The composite rolls are formed from a plurality of annular segments (45). Each segment preferably includes at least a pair of coolant openings (34) and means for aligning the coolant openings, such as a pair of alignment openings (26). The segments are axially aligned and structurally connected by a pair of connecting rods (42) extending completely across the width of the roll through the alignment openings and through appropriate end plates (96). Each roll includes a load supporting spindle (86) with each end of the roll sealed by a rotary seal (88). Coolant water is supplied to the composite casting roll by a flexible conduit (90) and heated water is removed through a flexible conduit (92).
