A simplified numerical method is proposed in this article to predict strip profile. The mill is simulated by beams (rolls) on the infinite elastic half space (between rolls and strip). The roll deflection and indentation are calculated using the influence coefficients and Boussinesq's equations respectively. The roll contours in the contact zone can be expressed in terms of the influence ...

A three roll mill or triple roll mill [1] is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it. The threeroll mill has proven to be the most successful of the ...
