Patent number: 9610623Abstract: A method controls the section sizes of a rolled product in a segment of a rolling line between at least two rolling stands, wherein each is provided with its own drive members, in which at least a detector located between the two rolling stands detects a characteristic size of the rolled product. A control unit compares the characteristic size of the rolled product with a reference size and acts on said drive members in order to hold the rolled product in an optimal drawing condition. The method includes setting a predefined value of an electric quantity of at least one of the drive members, measuring the reference size, and verifying the characteristic size of the rolled product in transit. If a deviation is detected between the characteristic size and the reference size, returning the characteristic size of the rolled product to the reference size.Type: GrantFiled: June 8, 2011Date of Patent: April 4, 2017Assignee: DANIELI AUTOMATION SPAInventors: Ferruccio Della Vedova, Lorenzo Ciani
