S6-high cold rolling mill

Due to their excellent features, the patented S6-high rolling mills are increasingly used for stainless steel strip rolling, either as in-line tandem mill for cold rolling or in the entry section of hot-strip stainless steel annealing and pickling lines.

Product description

The special features in S6-high rolling mills are the side-supported work roll and the intermediate roll drive with bending and lateral shifting. The diameter of the S6-high work rolls only amounts to approximately 1:10 in relation to the barrel length. This type of rolling mill is mainly used in inline or offline rolling mills for cold rolling of soft and hard strip to thinnest final gauges and for a wide range of strip widths. The utilization range is even wider when using the S6-high solution in combination with a standard 4-high mill.
