ABSTRACT:
A roll for use in a roll caster. The roll has a heat exchanger core and an outer generally cylindrical shell surrounding the core, the core and the shell defining an enclosed space. A working fluid is contained in the enclosed space. When molten metal is cast onto the shell, the working fluid in proximity to the outer shell changes from a liquid to a vapor. Due to the rotation of the roll, the liquid phase of the working fluid forces the vapor in proximity with the outer cylindrical shell to return to the area adjacent to the core. At this area, the vapor phase is condensed into a liquid which is then subsequently delivered radially to the outer cylindrical shell. In this way, the working fluid constantly changes from vapor to liquid and back to vapor again and acts to continuously remove heat from the molten metal cast onto the outer cylindrical shell. A single roll caster, a twin roll caster, and a melt spinning apparatus as well as an associated method are also disclosed.
