ABSTRACT
Figure 23.20 shows the relationship between the wave steepness change of the strip f'1). and the roll bending force change 1'1F for an HC mill and a conventional 4-high mill [8]. These relationships are expressed with straight lines in which the slopes are equal to the flatness control capability f. As follows from Fig. 23.20, the flatness control capability of the HC mill is substantially greater than that of a conventional4-high mill.
