Beschreibung
Zusammenfassung:	The invention discloses an online detection method and device for the tensile strain hardening index of cold-rolled thin strip steel. The online detection method for the tensile strain hardening index of the cold-rolled thin strip steel comprises the following steps: S1, establishing a unary linear regression statistical data model of the cold-rolled thin strip steel; s2, the applicability of the unary linear regression statistical data model is trained; and S3, applying the unary linear regression statistical data model to online detection of the tensile strain hardening index of the cold-rolled thin strip steel. The online detection method for the tensile strain hardening index of the cold-rolled thin strip steel is high in practicability, high in scientific performance and high in online control performance, the technical problem that the online control performance is poor due to a sample cutting off-line test method is solved, a large number of strip steel raw materials are saved, and the labor cost is lo
