My Father The Inventor | Invention & Technology Magazine
And so began his second great innovation, the Sendzimir cold-rolling mill. After hot steel slabs are rolled into heavy-gauge coils, the steel can be further rolled at room temperature into strip of very thin gauge. This is called cold rolling, though the process itself can heat the steel to around 250 degrees Fahrenheit.

Cold Rolling
Cold rolling is used for gauges usually in the range 0.4–3mm using cold reductions of 50–80%. During cold rolling the steel becomes hard and loses its ductility; therefore an annealing process is used to restore ductility and to develop almost the final properties. ... In practice, μ min ranges from 0.08 for the first pass on a Sendzimir ...
4C Profile Control in Sendzimir Mill
The Sendzimir mill is a rolling mill with cluster rolls for cold rolling such hard materials as stainless steel. Work rolls of small diameter are used to apply a strong rolling force to hard materials, but this makes it difficult to ensure the desired surface flatness.
