1results about How to "Avoid stacking steel accidents" patented technology

This invention discloses a method, apparatus, equipment, and medium for preventing steel pile-up in a coiler, belonging to the field of metallurgical industry technology. The method includes: obtaining the position of the lower pinch roll, and a first lateral movement speed of a hydraulic cylinder on the drive side and a second lateral movement speed of a hydraulic cylinder on the operating side of the lower pinch roll, wherein the hydraulic cylinders drive the lower pinch roll to move laterally; determining the lateral movement state of the lower pinch roll based on the position, the first lateral movement speed, and the second lateral movement speed, wherein the lateral movement state includes a stable lateral movement state and an unstable lateral movement state; when the lower pinch roll is in the unstable lateral movement state, adjusting the first lateral movement speed or the second lateral movement speed until the lower pinch roll is in the stable lateral movement state, so that the strip can be threaded normally. This method can improve the stability of the lower pinch roll lateral movement process, reduce the occurrence of strip failure to be threaded normally, and thus reduce steel pile-up accidents.
