roll pass design in section mill

A goodroll designconsiders the dynamics of girth growth vs reduction and the subsequent edge distortion when determining the correctrollcontour and fin angles. Reduction and Girth Control: The fin blade is a narrowrollsegment that fits into the open gap at the top of the partially formed tube.

Jun 19, 2017·Roll pass designis an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rollingmills.Roll pass designgenerally means the cutting of grooves in therollbody through which steel to be rolled is made topasssequentially to get the desired contour and size.

A New Method forRoll Pass DesignOptimisation

Improper tube size between each driven and sideroll pass. Improper forming indesign. Overly tight weldrollsettings. Rolls worn beyond tolerance. In Sizing. In the sizingsection, the following can cause tube marking: Overly tight drivenrollsettings; Loose driven stands; Driven rolls uncentered frompasstopass; Unparallel driven rolls
