Integrated method for control, alignment and adjustment of metal strip camber in processing lines

Abstract

An integrated process for the control, centering and regulation of the camber of a metallic strip in process lines wherein the strip (14) is passed over a centering group comprising a mobile frame (21) carrying one or more rolls (19) and which operates a rotation (ß) with respect to a fixed supporting frame (20) effecting a shift of a branch of the outgoing strip with respect to a branch of the ingoing strip, wherein the rotation (ß) of the mobile frame (21) takes place around an axis (B) tilted with respect to the plane on which the ingoing branch of the strip lies, which creates a steering angle (?) of the axis of the roll with respect to the perpendicular to the axis of the line by a rotation of a tilt angle (a) of the frames with respect to the plane perpendicular to the ingoing branch, wherein sensors (15, 16, 17) are positioned on the strip (14) arranged along the line and connected to an electronic control board (13) which receives the data of the advancing strip (position and camber) and, on the basis of a control algorithm, used by the controller.

Description

technical field [0001] The invention relates to an integrated method of controlling, centering and adjusting the camber of metal strips in a processing line. Background technique [0002] In the production line of metal strip, one of the most important requirements is to keep the strip "centered" with respect to the centerline in the processing area. Obviously, the higher the degree of alignment, the higher will be the parameters of the process such as repeatability and precision, and other aspects such as wear and maintenance costs will be reduced. In other words, the quality and production costs of the final product depend on the degree of centering that can be achieved over the widest range of strips processed. [0003] For the above reasons, line manufacturers and the component producers associated with them have been largely concerned with systems for controlling the trajectory of the strip, ie developing monitoring and centering systems for correcting the position of ...

Problems solved by technology

Therefore, the integrated action cannot be adjusted for the strip type, the tensile conditions involved or the material type and properties

[0014] The choice of α is thus a trade-off chosen by the line designer, and is not always suitable for the conditions of the incoming material (e.g. limited α values ​​produce moderate correction possibilities upstream, high α values ​​produce excessive correction in the material). stretching / deformation and may cause stretching of the edges or rupture of the material itself)
