Control method and equipment for suturing and centering thin strip steel for continuous annealing furnace

Abstract

The invention relates to the technical field of strip steel rolling, in particular to a control method and equipment for suturing and centering thin strip steel for a continuous annealing furnace. According to the control method and equipment, centering devices and side measuring devices are respectively adopted in the front and the back of suturing equipment, the centering devices are mainly used for detecting whether the center position of the strip steel moving forwards and the center position of the strip steel moving backwards are located in the center position of a unit, and the side measuring devices are mainly used for detecting whether the strip steel moving forwards and the strip steel moving backwards are placed right, namely whether the center line of the strip steel is parallel with the center line of the unit; a horizontal-moving hydraulic cylinder and a rotating hydraulic cylinder are respectively installed in front and back of the suturing equipment, the strip steel in front of the suturing equipment and the strip steel in back of the suturing equipment can be placed right and centered through cooperation between a first correction roller and a second correction roller, the suturing accuracy can be improved greatly, the strip breakage risk of the unit is lowered, and production is more smooth. According to the control method and equipment, the technical problems that existing control methods are poor in suturing accuracy and the strip breakage risk exists especially when the strip steel in front and the strip steel in back are different in width are solved.

Description

technical field [0001] The invention relates to the technical field of strip steel rolling, in particular to a control method and equipment for stitching centering of thin strip steel in a continuous annealing furnace. Background technique [0002] The cold-rolling and pickling units of major domestic steel mills have designed long production lines, which are extremely difficult to control. This is mainly reflected in the fact that the strip running on the production line in continuous production should be controlled within a certain horizontal range. It may cause damage to the product or damage to the production equipment, so that the production cannot be carried out. In order to avoid the deviation of the strip steel, a strip centering device is installed at an appropriate position on the production line so that the strip steel can be guaranteed to be on the center line of the unit, and the centering device Mounted on a measuring frame, the strip passes through the measuri...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a control method and equipment for seaming centering of thin strip steel in a continuous annealing furnace. One hydraulic cylinder for traversing and one hydraulic cylinder for rotating. The strip is adjusted through the rotating hydraulic cylinder and the hydraulic cylinder for traversing, and the strip is controlled to be aligned and centered. At the center of the unit, the edge measuring device mainly detects whether the forward strip and the rear strip are aligned, improves the alignment accuracy, and reduces safety hazards, and is used to solve the poor alignment accuracy of the existing control method and the unit has broken strips risk technical issues
