Coiling control method and device, medium and equipment

Abstract

The invention provides a coiling control method and device, a medium and equipment. The method comprises the steps of determining an actual rotation angle of a coiling block of a coiling machine, wherein the rotation angle is an angle required when a strip tail leaves a hot metal detector and the coiling block stops at a preset position; obtaining a reference rotation angle of the coiling block and an adjustment amount of the reference rotation angle; and controlling the coiling block to rotate in an inching mode at a preset adjusting angle if it is determined that sigma phi act is larger than sigma phi ref + / -delta, so that the actual rotating angle meets the condition that sigma phi act is smaller than or equal to sigma phi ref + / -delta, wherein sigma phi act is the actual rotation angle, sigma phi ref is the reference rotation angle, and delta is the calibration adjustment amount of the reference rotation angle. Thus, by determining the actual rotation angle and the reference rotation angle of the coiling block, when the actual rotation angle cannot enable a strip coil to stop in the optimal area, the coiling block is controlled to rotate in the inching mode according to the preset adjustment angle, so that the actual angle meets the condition that sigma phi act is smaller than or equal to sigma phi ref + / -delta, the coiling control precision is improved, the positioning precision of the tail of strip steel is improved, manual participation is not needed, adjustment time consumption is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metal coil tail control, and in particular relates to a coiling control method, device, medium and equipment. Background technique [0002] The coiling process of metal materials is generally the last process before delivery for use after the material controlled rolling and controlled cooling process. Therefore, its control accuracy is an important factor affecting the quality of finished products and the production capacity of production lines. According to the spatial arrangement of the tension roller, the coiling process can be divided into the pre-tensioning section, the tension control section, and the post-tensioning section. [0003] According to data statistics, the difficulty of coiling control of metal materials is concentrated in the tail control, that is, the loss of tension stage after the strip leaves the tension roller. The reasons mainly include the following points: 1) the distance erro...
