roll pass design in section mill

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

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.
