Tension-plate shape measurement-adjusting instrument

Abstract

The invention is used for on-line detection and regulation for the tension and the tensile stress distribution of band materials on a rolling production line of metal band materials, which mainly comprise a subsection roller and a subsection roller position regulating mechanism, wherein the subsection roller is a tensile stress distribution control roller (TDCR) published with the patent publication number of CN101288880A, each cylinder of the (TDCR) is newly provided with a set of position and pressure sensors which provide straightness signals of the band materials, and the straightness of the band materials is regulated by the cylinders according to the strength of the signals; the subsection roller is arranged on the subsection roller position regulating mechanism and is driven by each cylinder provided with a set of position and pressure sensors which provide tension signals of the band materials, and the tension of the band materials is regulated by the cylinders according to the strength of the tension signals. The invention separates the detection-control of the tension from the detection-control of the tensile stress distribution, thereby enhancing the precision of the detection-control of the tension and the tensile stress distribution and enlarging the control range. Furthermore, the invention can be combined with various plate shape control modes to form a plate shape comprehensive control system which can regulate the defects of various plate shapes.

Description

technical field [0001] The invention is applicable to the continuous production line of the strip, and more suitable for the continuous rolling production line of the metal strip. It can continuously detect the tension and the distribution of the tension stress on the strip, and adjust the tension and the distribution of the tension stress at the same time, and then control the shape. Background technique [0002] Tension, an important variable in the rolling process, has long been valued by people and used in shape control. The British Iron and Steel Research Association (BISRA) once proposed in 1972, a strip shape control scheme that uses changing the uncoiling tension as a control method. But it only considers changing the tension value, and does not involve the use of the distribution of tensile stress along the transverse direction to control the shape of the plate.
