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.
