Lateral Strip Guidance Damping Periodic Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the coiling process of hot-rolled strips, periodic lateral shifting occurs due to non-planar areas, tension loss, or other issues, leading to poor coiling quality, loose windings, and potential instability, as existing lateral guides fail to effectively manage these shifts, resulting in edge damage and buckling.
Innovation Solution
A regulating device is employed to dampen periodic shifting by adjusting the positions and forces of lateral guides relative to the rolled strip, using hydraulically actuated cylinders and position regulators to maintain strip alignment and stability, with input values including forces, positions, and differential measurements to control the guides' actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If lateral guides are used to guide the rolled strip, then the strip alignment is improved, but high forces occur leading to edge damage and buckling
Solution Approach 1:
The lateral guides are made dynamically adjustable through independent adjustment means that allow each guide to be positioned separately. This dynamic adaptability enables the guides to respond to varying strip conditions without applying excessive fixed forces, thereby preventing edge damage while maintaining alignment precision.
Solution Approach 2:
The invention changes the parameters of the lateral guides by allowing independent adjustment of each guide's position and applying forces. This parameter variability enables optimization of the guiding process to achieve proper strip alignment without generating harmful high forces that cause edge damage and buckling.
2Productivity
If periodic shifting is allowed to occur, then the coiling process continues, but coiling quality suffers with loose windings and instability
Solution Approach 1:
The independent adjustment means for the lateral guides provide a feedback mechanism that allows continuous monitoring and correction of strip position during coiling. This feedback system enables the guides to counteract periodic shifting in real-time, maintaining coiling quality with tight windings and stability while keeping the coiling process continuous.
3Device complexity
If lateral guides are fixed in position, then device complexity is reduced, but adaptability to different strip widths is lost
Solution Approach 1:
The lateral guides are designed with independent adjustment means that enable each guide to be positioned separately according to the specific strip width and conditions. This dynamic capability provides adaptability to different strip widths without requiring complex reconfiguration, as each guide can be independently adjusted to the appropriate position.

AI summary
The invention relates to a device for lateral guidance of a rolled strip transported on a roller bed, particularly a hot rolled strip in front of a winding device (3), having parallel first and second side guides provided on both sides of the rolled strip, said side guides being movable toward or away from one another by adjusting means that are adjustable independently of one another; the invention is characterized in that a control device (14, 15, 16), to which operating forces and/or positions of the side guides and/or of the rolled strip can be fed as output values in the guidance of the rolled strip, is provided for damping the periodic deviation of the rolled strip, and in that the control device (14, 15, 16) controls the positions of the side guides and/or forces that the side guides exert on the rolled strip based on the measured output values.
