ROLLING METHOD HAVING OPTIMIZED STRAIN PENETRATION

摘要

#CMT# #/CMT# The method involves determining a number of reduction stages, and rolling a rolling stock based on the determined number of reduction stages. Performance limits of a rolling mill are completely utilized in each reduction stage, or the performance limits of the rolling mill are not completely utilized in one of the reduction stages. An intermediate thickness of the rolling stock lies outside of a permissible thickness range (DB) when the number of reduction stages is reduced by one. The performance limits are completely utilized for the entire reduction stages that are reduced by one. #CMT# : #/CMT# Independent claims are also included for the following: (1) a computer program having a set of instructions to perform a method for operating a rolling mill for rolling a flat rolling stock from an initial thickness to a final thickness (2) a control device for a rolling mill for rolling a flat rolling stock. #CMT#USE : #/CMT# Method for operating a rolling mill (claimed) for rolling a flat rolling stock e.g. bar-shaped rolling stock and tubular rolling stock, from an initial thickness to a final thickness. #CMT#ADVANTAGE : #/CMT# The method permits simple and reliable operation of the rolling mill in an efficient manner, ensures optimized strain penetration in an easy and reliable manner, and reduces utilization of the performance limits of the rolling mill to minimum. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a timing diagram illustrating basic stitches with respective initial thicknesses.'(Drawing includes non-English language text)' dA : Initial thickness of flat rolling stock dZ : Intermediate thickness of flat rolling stock dZmax : Maximum limit of permissible thickness range dZmin : Minimum limit of permissible thickness range DB : Permissible thickness range.
