Study of the coefficient of friction and forward slip in cold rolling
In a Sendzimir mill cold rolling process, the coefficient of friction results found on this work may be used as an input in the mill mathematical model to improve the forward slip calculation (prior to cold rolling). Then, feedback logic may be implemented in the mill PLC, which will allow to refine the coefficient of friction input in the ...

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.
