Predicting Roll Runnability
The Tapio RQP can be used quite effectively to rank rolls and predict their runnability.
Statistical ranking of the rolls
This statistical ranking of the rolls is accomplished by using the COV% roll hardness and mean hardness (D. Wanigaratne, Appita 2010). This can be seen in the graph above. Groupings can be developed
