  • Rolling of Steel in a Modern Long Product Rolling Mill

    Roll pass design is an essential part of long product rolling process since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
