Abstract

The parting agent spray system is used with a roll casting machine to reduce the parting problems associated with releasing the casting-strip from the rolls. The parting system comprises a bank of self-cleaning spray nozzles for each of the upper roll and the lower roll of the caster. Each bank of nozzles is enclosed in its own individual housing which terminates proximal to the surface of the roll, and is movably located on a track. The housing is utilized to contain any excess graphite spray and prevent it from escaping from the area around the roll caster and contaminating the surrounding environment. The nozzles are grouped into zones, each zone connected to a parting agent solution source via an influent parting agent solution line, and connected to an air source via an air supply line for controlling the flow of the parting agent solution through each of the nozzles and atomizing the same, thus allowing the nozzles in each zone to be independently manipulated. Finally, each housing surrounding the nozzles is connected to a cyclone separator for removing the excess parting agent from the housing which has not been applied to said roll of the roll caster so as to eliminate contamination of the external environment with the excess parting agent. The excess parting agent which is extracted from the housing is separated out by the cyclone separator and contained for reuse.
