Control method and control system for right side drift of strip steel of acid continuous rolling unit

Abstract

The invention discloses a control method and system for right-side drifting of strip steel of an acid continuous rolling unit, and the method comprises the following steps: obtaining the rotating speed of a steel coil according to a main motor encoder, and calculating the outer diameter of the steel coil according to the rotating speed of the steel coil; calculating the actual drift length according to the outer diameter of the steel coil; and converting the actual drifting length into the number of rotation turns of the coiling machine, and controlling the rotation of the rotating machine. The actual drifting length is calculated according to the outer diameter of the steel coil, the number of turns of rotation of the coiling machine is set, when the steel coil drifts to the right side, a quality inspector can conveniently inspect the plate surface condition on the walking beam saddle, time and labor are saved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of acid tandem rolling mill control, in particular to a control method and a control system for tail flicking on the right side of strip steel in an acid tandem rolling mill unit. Background technique [0002] In the production of the continuous acid rolling mill, after each steel coil shearing and tailing, the coil tail will be pressed after the coil is finished, and then the unloading trolley starts to unload the coil and transport it to the saddle of the walking beam. At the bottom of the coil, the quality inspector cannot check the surface condition of the steel coil on the saddle of the walking beam and make the corresponding steel coil grade. If the steel coil is transported to the inspection table for inspection, it will not only waste a lot It also wastes manpower, so how to flick the tail of the steel coil to the right is very important for the inspection of the steel coil surface. SUMMARY OF THE ...

Problems solved by technology

[0002] In the production of the acid tandem mill, each time the steel coil is sheared and flicked, the coil tail will be pressed after the coil is finished, and then the coil unloading trolley will start to unload the coil and transport it to the walking beam saddle, because the coil tail is always on the steel The bottom of the coil prevents quality inspectors from viewing the steel coil surface on the walking beam saddle and making a corresponding steel coil grade. If the steel coil is transported to the inspection table for inspection, it will not only waste a lot of It also wastes manpower, so how to swing the tail of the steel coil to the right is very important for the inspection of the steel coil surface
