Leveling flat

Sep 11, 2007· Ideally, the rolling mill would apply equal pressure across the entire width of the strip, which would produce equal elongation and perfectly flat strip But in reality, mill rolls deflect under load, creating more pressure and elongation at the edge of the strip and producing a ,...

Bridle Roll Unit Summary

A Bridle roll unit can affect the tension in the strip according to the formula T2 = T1eμα, where T1 and T2 are the tensions on either side of the bridle roll, μ is the coefficient of friction between the roll and the strip, and α is the angle of wrap of the strip around the roll in radians...

Hot Strip Mill

Work rolls in hot strip mills wear due to friction between the roll surface and hot strip (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill) The wear is uneven from one end of the barrel to the other...
