Product description

The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths, as well as for break-down rolling in offline applications.
