Steel Pipe Manufacturing Processes mandrel mill process

In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube.

Analysis of roll stack deflection in a hot strip mill SciELO

This changes the initial set value of roll gap between the work rolls (Wilms et al. (1985)). Flatness is dependent on the roll gap or clearance between the working rolls during the process of rolling. Strip profile and flatness can be influenced by the mill features like work roll bending and CVC (Continuous Variable Crown) shifting.
