How exactly does a rolling mill work? - Practical Machinist

A mill is designed to work well within its elastic deformation stress range while the work-piece is in its plastic deformation stress range. The yield stress of C12 bronze is 18,000 psi. The area undergoing deformation is most of the contact area between the rollers and the sheet multiplied by the width of the sheet.
