STECKEL MILL SPECIALIZED SOLUTIONS THROUGH ENGINEERING EXPERIENCE The Steckel Mill occupies a special niche in hot flat rolling, operating at a lower economic volume than tandem hot strip mills but capable of greater widths and especially
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.
DEMAND FOR ROLLINGMILL ROLLS BITE ANGLE AND COEFFICIENT OF FRICTION the contact area of hot rolled material during rolling may be unique but neck loads and contact stress in all other applications (cold rolling, back up rolls) have similarities in other components.

reversible, rolling in an intermediate mill and in a finishing mill, possible followed by some kind of heat treatment. For steel qualities that can be deformed at higher speeds without problems, some of the last passes can be performed in a wire block. The difference between shape rolling and hot strip rolling is that instead of flat rolls, the
