What is z mill?

Z mill, also known as Sendzimir mill, is a specialized rolling mill designed for cold rolling of thin sheets of metal. It was developed by the Polish-American engineer Tadeusz Sendzimir in the 1920s.

The characteristic feature of the Z mill is its ability to apply high-pressure rolling through a set of small rolls that are arranged in a cluster. The rolls are supported by intermediate rolls and are smaller in size, which results in significant improvements in the quality of the rolled material.

Z mills are commonly used to produce very thin sheets of metals like stainless steel, aluminum, and copper. They are also used to produce tight tolerance strip materials that maintain excellent flatness and surface quality. The high-pressure rolling process of the Z mill can create a smooth, reflective surface finish on the material.

Overall, the Z mill is an essential part of modern steel production and is widely used in industries like automotive, aerospace, and electronic components.
