PROCEDURE FOR THE PRODUCTION OF DEFINED CHARACTERISTICS OF PRODUCTS WHEN ROLLING STEEL QUALITIES IN THE AUSTENITICAL, MIXED AUSTENITIC-FERRITIC AND FERRITIC AREA.

摘要

Procedure for the production of defined product characteristics, when rolling steel grades in the austenitic, mixed austenitic - ferritic and ferritic zone, applying a measurement procedure for the determination of the opening between cylinders of a pair of working cylinders by means of registration of the absolute position of the support or working cylinders on the farthest side respectively of the opening between cylinders by optical position measurement, characterized in that in relation to the absolute measured position of the cylinders, by sensors arranged next to each other along the cylinder, the upper edge of the upper cylinder, or the lower edge of the lower cylinder, is registered by sectors, in each case along the length of the table; The results of the measurement intervene in an appropriate adjustment to influence the geometry of the opening between cylinders and the product to be laminated, by means of a model that takes into account, together with the influences of the flexion adjustment systems and the cylinders, the bending of the cylinders, the flattening between the cylinders, the flattening between the working cylinder and the product to be laminated, as well as the wear and thermal bulging of the cylinders, whose adjustment provides, together with the absolute thickness required, the thickness profile and the flatness criteria.
