This invention belongs to the field of rolling mill thickness compensation technology, specifically disclosing a rolling mill thickness compensation control method based on an AGC hydraulic cylinder system. By dividing a continuous steel plate into independent micro-elements with time-sequence identifiers, the remaining travel distance of each micro-element from the roll gap is accurately calculated through real-time speed integration.

Roll gap compensation is only triggered when the predicted sudden change in rolling force occurs, achieving online verification of the effectiveness of thickness deviation disturbances and minimizing redundant adjustments and additional system disturbances caused by blind compensation.

This invention proposes an asphalt stripping device and method for recycled asphalt mixtures, belonging to the field of recycled asphalt mixtures. The device features an axially rotating inner shell with a gap between its outer and inner peripheral walls. A window is provided on the outer peripheral wall of the inner shell. A first scraper and a second scraper are positioned within the gap and on the outer and inner peripheral walls of the inner and outer shells, respectively. The first scraper drives the mixture to rotate synchronously with the inner shell, causing the second scraper to scrape the surface of the mixture. A vibrating plate is positioned within the window and vibrates along the direction of the window, reducing the width of the gap. The vibration of the vibrating plate on the inner shell accelerates the rolling speed of small particles, separating them from larger particles. Simultaneously, the vibration raises the surface of the vibrating plate above the surface of the inner shell, reducing the gap width. This reduced gap hinders the movement speed of large particles within the gap, prolonging their residence time, allowing the second scraper to scrape the surface of the large particles, resulting in asphalt stripping.
