Guidelines for Cross-roll Elongation. For cross-rolling elongation, two main requirements relate to the as-pierced shell. These are filling the hump height section to 80 to 90 percent of its design and maximizing inlet side grip. Both requirements are related to the roll pass design in the Assel mill.
