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.
