ABSTRACT:
A method of determining a draft schedule for a continuous rolling mill of n stands which gives consideration to both sheet crown and flatness is disclosed. Using (n-1) simultaneous equations for sheet crown, flatness, and power distribution, the exit side thickness and flatness at each of stands 1 through (n-1) are solved for. The process of solving for thickness and flatness is repeated until the flatnesses at a desired number of stands fall within permissible bounds. The draft schedule obtained by this method allows target values of crown and flatness to be met for the entire rolling cycle.
