Problems solved by technology

The most widely used are the piezomagnetic type of ABB company in Sweden and the air bearing type of DAVY company in the United Kingdom. The problems in use are: the slip ring mechanism is the core component, and its machining accuracy is very high, and the signal output lead wire mechanism is complicated. , At the same time, it is easy to wear, which reduces the service life of the instrument and increases the production cost

Abstract

The invention discloses a detecting roller, a contact type shape meter and a detection system, wherein the detecting roller comprises a ring piezomagnetic core, a stator core, closed induction coils, excitation coils and output coils, the induction coils are arranged inside the ring piezomagnetic core, the excitation coils and the output coils are independent and arranged in the stator core, the stator core is concentrically arranged in an inner hole of the ring piezomagnetic core, and the ring piezomagnetic core rotates around the stator core under the driving of a plate strip to be detected, so that no slip ring structures are needed, and accordingly the service life of the shape meter is prolonged.

Description

technical field [0001] The invention relates to the field of shape detection of a strip-foil cold rolling mill, in particular to a detection roller, a contact type shape meter and a detection system. Background technique [0002] In the metallurgical industry, the shape quality of strip rolling is one of the important quality indicators for evaluating the quality of cold-rolled strip products, which will directly affect the quality of subsequent deep-processing products. Therefore, shape detection is the core key in the field of cold rolling technology. At present, the contact-type shape detection instruments used on the strip and foil rolling line mainly include: piezoelectric type (stressmeter roll of ABB company), piezoelectric type (BFI roll of German Iron and Steel Research Institute) and air bearing type (DAVY The company's vidimon roller and BRONE's air bearing detection roller) and other forms. The most widely used are the piezomagnetic type of ABB company in Swede...
