Field of the Invention The present invention relates to a stainless steel strip build-up line in which a stainless steel strip before cold rolling is subjected to a pre-treatment such as connection of a dummy material and trimming of the stainless steel strip. The present invention relates to a stainless steel strip build-up line capable of removing adhered dust and cleaning the stainless steel strip.

ず、その分だけ歩留りが低下する。2. Description of the Related Art Generally, a stainless steel strip after hot rolling is subjected to annealing and pickling (the annealing may be omitted depending on the type of steel and application), and then cold-rolled by a reverse rolling mill such as a Sendzimir mill. Rolled. In this reverse rolling, a coiled stainless steel strip (hereinafter referred to as a coil) is rewound, and the stainless steel strip is reciprocated while being wound up to perform cold rolling until a predetermined thickness is obtained. Therefore, the front and rear end portions of the stainless steel strip wound around the winding machine / rewinding machine cannot be rolled, and the yield is reduced accordingly.

すようにしている。Therefore, prior to the cold rolling, a dummy material is welded to the front and rear ends of the stainless steel strip in the build-up line, or the coil is welded by several turns to increase the size of the coil to be rolled. Part lengthening is performed. However, the thickness of the steel strip and the dummy material or the thickness of the steel strips do not always match each other, and there are many cases where a step (hereinafter referred to as a “stepped portion”) occurs in a connection portion by welding. If the steel strip is wound with the stepped portion, the steel strip is broken at the stepped portion, and the product quality is impaired. Therefore, after welding, the stepped portion is ground with a grindstone to eliminate the step.

もある。[0004] Further, if minute cracks are present at both ends (hereinafter referred to as "ears") in the width direction of the stainless steel strip, the sheet is broken in the next step of cold rolling due to the cracks. In the line, the edge of the steel strip is cut and removed (side trimming, edge cutting), and both end faces in the width direction are ground with a grindstone. Thus, in the build-up line, pre-processing such as welding and side trimming is performed before cold rolling, but this pre-processing may be performed before annealing or pickling or may be performed later.

Is performed. Also, on the entry side of the build-up line, a shearing operation is performed by a shear to trim the rear end of the steel strip prior to welding.

If these dusts are wound up while adhering to the surface of the steel strip, dents and flaws are generated on the surface of the steel strip. Further, in the cold rolling in the next step, the dust adhering to the surface of the steel strip adheres to the rolling rolls, and contaminates the rolling rolls, or generates dents in the rolling rolls. The roll contamination deteriorates the surface gloss of the rolled product, and the roll dent causes the rolled product to have a convexity.

The fine oxide scale powder on the steel strip surface peels and floats and adheres to various rolls and equipment on the build-up line, causing dents and flaws on the steel strip surface, and the oxide scale powder scattered around. There is also a problem that the working environment is deteriorated.

The present invention has been made in view of such circumstances, and it is possible to remove dust such as grinding powder, cutting powder, or oxide scale powder from a stainless steel strip before cold rolling, and to clean the surface of the stainless steel strip. The purpose is to provide a build-up line for steel strip.
