The concept of the Z-High® mill is a revamping of a classic 4-High 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. Harder materials can be rolled without intermediate anneals; as a result, a better surface can be produced.

A dynamic model coupling vertical and horizontal vibrations is also established to analyze the vibration characteristics of a Sendzimir twenty-high cold roll mill based on the rolling force fluctuation model. Good agreement between the simulated results and the experimental results verifies the effectiveness of the established models.
The paper compares and contrasts various controller possibilities and is intended to provide a "cookbook" of shape control tools and strategies for Sendzimir mills. Deals with the problem of shape (or flatness) control for Sendzimir 20-roll cold-rolling steel mills. Such mills, with a variety of shape actuators, offer the control engineer considerable choice in the configuration and design of ...
