  • Strip casting
    Patent number: 5588479
    Abstract: A molten metal casting pool is confined between a pair of casting rolls (12) by side closure plates (18) applied to the ends of the rolls (12) by thrusters (21). Side closure plates (18) are mounted in holders (25) which are pivotally connected to thrusters (21) by pivot pins (26) so that the side plates (18) can tilt about the pivot connections. Pivot pins (26) are located at such height above the nip between rolls (12) that effect of outward pressure on plates (18) by molten metal of the casting pool is such as to rotationally bias the plates (18) about the pivots in such directions that their bottom ends are biased inwardly to produce increased scaling pressure at bottom of casting pool.
