A control method and equipment for seaming centering of thin strip steel in continuous annealing furnace

Abstract

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. The present invention adopts a set of centering devices and a set of side measuring devices before and after the sewing equipment. Whether the running strip and the rear strip are aligned, that is, whether the centerline of the strip is parallel to the centerline of the unit. At the same time, a transverse hydraulic cylinder and a rotary hydraulic cylinder are respectively installed at the front and rear of the sewing equipment. Through the cooperation of the first deviation correction roller and the second deviation correction roller, the front and rear strips of the sewing equipment can be aligned and centered, which can greatly improve the sewing quality. Accuracy, reduce the risk of belt breakage of the unit, and make production run more smoothly. The invention solves the technical problem that the stitching accuracy of the existing control method is poor, especially when the width of the front and rear strips is inconsistent, and there is a risk of strip breakage.

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...

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
