DESCRIPTION

Plate rolls have gotten seriously big. Machine pits are deeper, the frames massive, the rolls ever larger. Certain machines have specifications stating they can roll plate of certain yield strengths to 4, 6, and 7, even 11 inches—cold.

According to sources, several factors are spurring demand. First is increased demand from the sectors providing infrastructure and power generation. Second, a lot of old iron remains in heavy fab shops; many are upgrading, and the type of machine they're purchasing has made such heavy rolling practical and cost-effective: the variable-geometry plate roll.

Steel plate rolls–whether they have two or three bottom rolls–all have a top roll. The top roll can be sized to roll plate into cylinders or cylinder segments to radii close to the diameter of the top roll.  However, relatively small top rolls can deflect in the center under the pressure of curving steel plate.  Alternately, larger-diameter top rolls deflect less but limit the machine to rolling only larger diameters.
