The concept of the ZHigh® mill is a revamping of a classic 4High mill with a system that uses a much smaller work roll. This configuration allows the mill to take heavier reductions per pass and can achieve thinner gauges. ... The evolution to the current 20High Cluster Sendzimir Mill from the early 12High configuration was pioneered by ...

The acting force on the roll system of Sendzimir mill was analyzed using 3D FEM. The roll gap pressure distribution and the acting force between rolls S andO, rollsO and I, rollsO and J, rolls I and A, rolls I and B, as well as rolls J and B were analyzed. The results showed that the roll gap pressure mainly affected the roll surface layer, 50 mm for backup roll; the roll gap pressure ...

Tadeusz Sendzimir, a Polish émigré, came to the United States in 1939 to work at Armco Steel in Middletown, Ohio. Sendzimir had earlier developed radical processes for galvanizing steel (1931) and cold rolling steel (1933). Sendzimir's rolling process departed dramatically from the multistand continuous process developed by John Tytus Armco ...
