Abstract
The caster roll (10) is used in the manufacture of metal plate, strip, sheet, or foil. The caster roll (10) includes a cylindrical roll core (12) and at least one metal overlay (14) formed on the roll core (12). The at least one metal overlay (14) defines a plurality of cooling passages (34) for conducting a cooling medium through the at least one metal overlay (14) to cool the roll (10) during use. Additional metal overlays (16) may be formed on top of the at least one metal overlay. (14). The cooling passages (34) may also be formed in the roll core (12).
Claims48
A roll for use in manufacturing metal plate, strip, sheet, or foil, comprising:
- a cylindrical roll core having a central longitudinal axis and defining a plurality or longitudinally extending cooling passages for conducting a cooling medium through the roll core to cool the roll during use, the cooling passages being located within the interior of the roll core;
- and
- at least one metal overlay formed on the roll core.
A roll for use in manufacturing metal plate, strip, sheet, or foil, comprising:
- a cylindrical roll core having a central longitudinal axis;
- a metal overlay formed on the roll core, the metal overlay defining a plurality of cooling passages for conducting a cooling medium through the metal overlay to cool the roll during use;
- the cooling passages comprising at least one inlet cooling passage and at least one outlet cooling passage;
- the inlet cooling passage being in fluid communication with the outlet cooling passage;
- and
- the cooling passages extend substantially parallel to the central longitudinal axis of the roll core.
A roll for use in manufacturing metal plate, strip, sheet, or foil comprising:
- a cylindrical roll core having a central longitudinal axis;
- a first metal overlay formed on the roll core, the first metal overlay defining a plurality of cooling passages for conducting a cooling medium through the first metal overlay to cool the roll during use;
- the cooling passages comprising at least one inlet cooling passage and at least one outlet cooling passage;
- the inlet cooling passage being in fluid communication with the outlet cooling passage;
- the cooling passages extend substantially parallel to the central longitudinal axis of the roll core;
- and
- at least one additional metal overlay formed on the first metal overlay.
