Patent ID: 7354492

Claim:
A method for optimizing the production technology of rolled products, said optimizing being effected by determination of operation settings of a rolling mill, comprising the steps of: at the rolling mill, positioning at least one of a sensor and a measurement arrangement to determine variables of a rolled strip when said strip moves; reading and computer-aided processing of indications of said sensors and measuring arrangements, and working-out the controlling actions to which the rolling process is to be subjected; said method being characterized in that it further includes the following steps: presetting at least one rolling process parameter needed to be monitored for rolled strips according to a production specification for a given batch of rolled products, wherein the production specification includes: at least one preset limit for measured quantities of the at least one preset parameter; and at least one quantity corresponding to a portion of a length of a rolled strip, which quantity is usable to determine if a sufficient length of a strip satisfies the production specification; systematic measuring of quantities of the at least one preset parameter when a rolled strip moves along the rolling mill; presetting at least one of a number and a length of a plurality of sections of the rolled strip, for each of which sections the measured quantities of the the at least one preset parameter are obtained separately; for each section, averaging the measured quantities that relate to the given section of the rolled strip; comparing the averaged quantities for the sections with the at least one preset limit of the production specification to determine data that indicates a number of sections in which the averaged quantity measured for the respective sections at least one of: is less than, is greater than, and is equal to, the at least one preset limit of the production specification; comparing the determined data to the quantity of the production specification corresponding to the portion of a length of a rolled strip correcting rolling mill settings for rolling of a next strip responsive to the comparison between the determined data and the quantity of the production specification, indicating that a sufficient length of the strip does not correspond with the production specification.
