Cooling pad assembly for a belt casting system
A cooling pad for a belt casting system includes a first nozzle arrangement and a second nozzle arrangement. In some embodiments, the first nozzle arrangement includes an elongated nozzle assembly that includes a base defining a receiving area, a first insert positionable within the receiving area, and a second insert positionable within the receiving area. The first insert and the base together define a first elongated dispensing slot. The second insert is adjustable relative to the first insert, and the second insert and the base together define a second elongated dispensing slot. In various embodiments, the second nozzle arrangement includes a plurality of multi-position nozzles, each movable between a base position and an offset position such that the heat transfer rate may be locally controlled across the cooling cavity.
1. A cooling pad assembly for a belt casting system, the cooling pad assembly comprising:
a nozzle arrangement comprising a plurality of multi-position nozzles configured to dispense a coolant, wherein each multi-position nozzle comprises a stem and a cap that is rotatably and longitudinally movable along the stem between a base position and an offset position, wherein the cap comprises a dispensing end, and wherein:
in the base position, the dispensing end is arranged in a cooling pad nozzle plane relative to a central plane of a casting cavity of the belt casting system; and
in the offset position, the dispensing end is offset by a distance from the cooling pad nozzle plane and away from the central plane.
2. The cooling pad assembly of claim 1 , wherein the distance is from 0.1 mm to 2.0 mm.
3. The cooling pad assembly of claim 1 , wherein the nozzle arrangement is a first nozzle arrangement, wherein the cooling pad further comprises a second nozzle arrangement upstream from the first nozzle arrangement and comprising an elongated nozzle assembly, the elongated nozzle assembly comprising:
a base defining a receiving area;
a first insert positionable within the receiving area, wherein the first insert and the base together define a first elongated dispensing slot; and
a second insert positionable within the receiving area, wherein the second insert and the base together define a second elongated dispensing slot that is offset from the first elongated dispensing slot in a longitudinal direction,
wherein the cooling pad is configured to dispense a coolant through each of the first elongated dispensing slot and the second elongated dispensing slot, and
wherein the first insert is independently adjustable relative to the second insert within the receiving area.
4. The cooling pad assembly of claim 1 , wherein the dispensing end of each multi-position nozzle comprises a plurality of edges forming a hexagonal perimeter and such that the dispensing end comprises a hexagonal face, and wherein an intersection of two edges of the plurality of edges comprises a position indicator.
5. The cooling pad assembly of claim 1 , wherein across a width of the cooling pad that is transverse to a casting direction, at least one multi-position nozzle is in the base position and at least one multi-position nozzle is in the offset position.
