Abstract
This disclosure relates in part to a hot extrusion press wherein the extrusion is cooled immediately after the extrusion operation by arranging a cooling tube including a cooling nozzle within the platen of the press and a second cooling nozzle between the platen and a water tank to which the extrusion is ultimately transferred for final cooling. The second cooling nozzle is employed to cool the extrusion and on the occasion of a cobbled extrusion, it is employed to drain the cooling tube and at the same time prevents water from flowing from the tank into the tube.
