Optimization of a Cold Rolling Mill

I summarizes the typical thicknesses and rolling speeds for each mill type. Not surprisingly, as the material gets thinner, the speeds increase dramatically. Hot Roughing Mill Hot Finish Mill Cold Rolling Mill Maximum Thickness > 400 mm 20-50 mm 3-20 mm Minimum Thickness 20-50 mm 3-20 mm 0.100 mm Rolling speeds (meters per min) ~ 100 ~ 1000 ~ 2000

Productivity Optimization of Cold Rolling Mills - Steel in ...

The rolling speed at which the productivity is maximum is conventionally called the critical rolling speed v cr.The value of v cr depends on the coefficients c 1 –c 7, which are determined by the parameters of each group of mills (thickness and width of rolled products, roll change rates, rolling cycle components, etc.).The study of the influence of the main mill parameters and the rolling ...
