The Right Roll Starts With the Application

When selecting a rolling mill roll, one of the first questions is usually: “What is the hardness?”

It is an important question, but two rolls with similar hardness can perform very differently. One may maintain a stable profile throughout the campaign, while the other develops rapid wear, thermal cracks, or spalling.

The difference often comes down to whether the roll is properly matched to its working conditions.
