Roll pass design in continuous bar mills - SlideShare

2015-5-18 · Thumb rules in rolls pass design  Fittings from oval to round must be 0.3 to 0.7.  For ovals width to height ratio must be less than 3.0. 13. Spread  When the steel is compressed in the rolls it will obviously move in the direction of least resistance, so usually there is not only longitudinal flow but also some lateral flow.
