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.
