Description

Technical Field

[0001] The invention belongs to the field of steel coil turning and transporting systems, and in particular relates to a coil centering device, a centering method and a system. Background Art

[0002] The steel coil transportation system is a key equipment in metallurgical steel plants. It is a bridge connecting upstream and downstream units and is responsible for the coil connection, transportation, and rewinding of steel coils. Whether the steel coil transportation system can accurately and reliably transport the steel coils to the next process according to the process requirements has become a key link that directly affects production. The steel coil transportation system is diverse, including vertical coil transportation system, horizontal coil transportation system, and steel coil reversing transportation system. In order to meet the process requirements of upstream and downstream units, it is often necessary to switch between vertical coils and horizontal coils. For example, the steel coils coming out of the bell-type annealing furnace are generally vertical coils. Before the steel coils come out of the bell-type annealing furnace and enter the downstream leveling unit or rewinding unit, the rewinding machine in the steel coil reversing transportation system needs to turn the vertical coils into horizontal coils. The process is as follows: the vertical coils coming out of the bell-type annealing furnace are transported by the overhead crane to the entrance saddle of the steel coil reversing transportation system, the vertical coils at the entrance saddle are transported by the entrance steel coil transportation device to the rewinding saddle, the vertical coils are turned into horizontal coils by the rewinding machine, and the horizontal coils are transported to the downstream unit by the exit steel coil transportation device.

[0003] Because there is a deviation in the lateral position when the overhead crane lifts the upright coil to the entrance saddle of the steel coil turning transportation system, that is, there is a deviation between the center line of the upright coil and the center line of the entrance steel coil transportation device in the direction perpendicular to the entrance steel coil transportation direction, and the entrance steel coil transportation device cannot correct the lateral position deviation of the upright coil in the process of transporting the upright coil from the entrance saddle to the turning saddle. Therefore, when the upright coil is turned into a horizontal coil, the impact on the turning machine is very large, which seriously affects the service life of the turning machine and poses a great safety hazard.
