Abstract
A more uniform cooling system for direct strip forming processes on chilled drums wherein the drum 1 is hollow and is partially filled with a coolant pool 6. A central tube 7 provides coolant spray 8 to the portions of the drum interior when not covered with the coolant pool. Patterned cooling for thickness control is practiced by changing the heat conduction through the drum wall at selected locations.
