ABSTRACT
Let us assume that the base strip center crown c0 corresponds to the strip width w0 , strip modulus M 0 , backup roll diameter ~0 , and work roll diameter Dwo ; the backup and work roll crowns as well as positive and negative roll bending forces are equal to zero. One of the main tasks of a strip profile model is to use the values that are related to the base strip center crown c0 to determine the derivative strip center crown c that corresponds to the strip width w , strip modulus M , backup roll diameter Db , work roll crown cw, positive roll bending force F ww, and negative roll bending force F bw .
