With innovative and patented solutions, ANDRITZ Sundwig is a global leader for the design of high quality cold rolling mills . ANDRITZ Sundwig solutions are known for their customer-oriented design; especially the 20-high rolling mill, the S6-high rolling mill and the inline / offline skin pass mill solutions.
andritz Cold rolling mill technology Carbon steel products andritz . This allows to produce cold Single-stand reversing mill 4-high, 6-high, (S6-high) 150,000 Combined multizone cooling and strip blow-off system Dry-temper roll cleaning equipment Model predictive control system
Due to their excellent features, Sundwig S6-high (supported 6-high) rolling mills are mainly used for cold rolling of a wide range of strip hardnesses, widths, and gauges, either in processing lines as high-capacity reduction mills or offline as reversing reduction mills.
With high-capacity reduction in the S6-high operating mode for high-strength material grades, in the 4-high operating mode for soft and intermediate material grades, and for skin passing or temper rolling in the 4-high operating mode, the 4/S6-high combination mills are used wherever it is not economical to have several mills for these applications due to the quantities involved.
