Definitions

the molten metal may be poured from a ladle into a smaller vessel or series of vessels from which it flows through a metal delivery nozzle located above the nip so as to direct it into the nip between the rolls, so forming a casting pool of molten metal supported on the casting surfaces of the rolls immediately above the nip and extending along the length of the nip.
This casting pool is usually confined between side plates or dams held in sliding engagement with end surfaces of the rolls so as to dam the two ends of the casting pool against outflow, although alternative means such as electromagnetic barriers have also been proposed.
the ladle is of entirely conventional construction and is supported on a rotating turret (not shown) whence it can be brought into position over the tundish 17 to fill the tundish.
the tundish may be fitted with a sliding gate valve 47 actuable by a servo cylinder to allow molten metal to flow from the tundish 17 through the valve 47 and the refractory shroud 48 into the distributor 18.
the caster includes a lifting means in the form of four fluid cylinder actuated hoists 71 supported by the machine frame 11 and located to underlie the corner regions of the roll cassette frame 102 when the roll cassette 13 is at the intermediate position - as can best be seen in Figures 2 , 4 and 5 .
Actuation of the hoists 71 lifts the roll cassette 13 to the casting position.
the upward movement of the roll cassette 13 is limited by inwardly extending flanges 75 on the guide rails 89 which are contacted by outwardly extending flanges 77 on the roll cassette frame 102.
the illustrated caster has been advanced by way of example only and it could be modified considerably.
the roll supports be mounted on linear bearings for strict linear movement. They could alternatively be supported from the cassette frame on pivot arms to allow arcuate movement providing the necessary lateral movement of the rolls to permit appropriate springing movement. This arrangement would enable further reduction of the effective friction on roll movement.
the roll biasing units 51 could be mounted on pivot arms and brought into position for connection with the installed cassette by actuation of hydraulic or pneumatic cylinder units acting on the supporting pivot arms. The precise manner in which the cassette is transported into and out of the casting machine could also be varied.
