Sendzimir

Z-High® Mills Sendzimir Z-High® Mills were developed to combine the advantages of the Sendzimir cluster-type rolling mill with those of the 4-High Revamp Existing Mill The Z-High® concept permits the revamping of a classical 4-High mill with a system that uses amuch smaller work roll.

Sundwig S6-high cold rolling mill

A special feature of Sundwig S6-high rolling mills are the side-supported work rolls The patented Sundwig S6-high side support stabilizes the work rolls in this type of mill stand using mechanical, hydraulic lateral support equipment, thus preventing lateral excursion of these rolls.

Advanced single and multidrive systems for plate rolling mills

ABB drive systems for demanding process control The large and rapid power variations, from no-load to overload, places a high strain on all components of the electrical system The material enters the mill at thread speed and is accelerated to a rolling speed of 2 to 3 m/s in a few seconds.

Rolling (metalworking)

A tandem mill is a special type of modern rolling mill where rolling is done in one pass In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively The number of stands ranges from 2 to 18.
