Run out rollers in the light plate mill were specified to be S.G. iron. After 3 years of production it was evident that wear and corrosion had become significant problems. Weldclad 8 was recommended as a replacement material. Results of trials are shown in the table below:

 

Roll Material Type	Average Wear per 1M Tonnes	Cost per Roll
S.G. Iron (wet areas)	10.16mm	850
S.G. Iron (dry areas)	2.29mm	850
Weldclad 8 (New)	0.28mm	1100
Weldclad 8 (Re-welded)	0.28mm	700

 

The use of Weldclad 8 was a great success, giving a durable and consistent finish from roll to roll, and equal performance in wet and dry areas. Weld reclamations of previously welded rolls proved that the same performance benefit could be maintained with lower costs.
