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.

In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot- or cold-rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot- and cold ...
