282 Abstract— Galvalume is a Continuous Galvanizing Line. In Galvalume the Zn-Al coating is done on the CR sheets to inprove their corrosion resistance and to improve their life. JSW Ispat Steel Ltd. Kalmeshwar has to frequently replace the sink roll assembly used in Zn-Al tank of the Galvalume.The mean time between replacements is very less as compared to expected mean time between failures (expected MTBF). This is due to deposition of zinc dross on the surface of roller. This result in uneven or improper Zn-Al coating on sheet surface. To avoid this sink roll has to replace. The frequent replacement of roller assembly results in Stoppage of production, material loss, start-up loss and increased cost of production. This paper proposes an alternative material to extend the life of sink roll and the thermal-spray coating of various materials on traditionally used sink roll of SS316L roll surface.
