Welded Wear Resistance in Table Rollers |
| | | | 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. |
