Description

Large-caliber metallurgical paper sleeve with oblique stress distribution structure Technical Field The utility model relates to the technical field of metallurgical processing, in particular to a large-caliber metallurgical paper sleeve with an oblique stress distribution structure. Background Metallurgy is a process of extracting metal raw materials from minerals or other substances containing metal substances, and covers the whole refining extraction process from mining of a mine hole to metal purification, and is generally used for processing materials such as steel, iron, gold, silver, copper and the like, and the extraction method is not limited to the technologies such as a fire method, a wet method, an electrolytic method and the like. When the metal material is refined and rolled into a thin metal sheet, the thin metal sheet is wound and collected by using a paper sleeve, and the paper sleeve has certain thickness and hardness and cannot be collapsed under the winding of the metal sheet layer by layer, but the paper sleeve is often influenced by axial, radial and other composite stress in the transportation process, the paper sleeve is inevitably crushed and broken, and the wound metal sheet is also broken. At present, a novel large-caliber metallurgical paper sleeve with an oblique stress distribution structure is provided to solve the problems. Disclosure of utility model The utility model aims to provide a large-caliber metallurgical paper sleeve with an oblique stress distribution structure, so as to solve the problem that the paper sleeve is easy to collapse in the background technology. The technical scheme is that the large-caliber metallurgical paper sleeve with the oblique stress distribution structure comprises an inner paper sleeve, an outer paper sleeve is fixed on the outer surface of the inner paper sleeve, spiral paper strips I are wound on the outer surface of the outer paper sleeve, spiral grooves are formed between adjacent spiral paper strips I, and spiral paper strips II are wound in the spiral grooves. As a further technical scheme of the utility model, the winding direction of the first spiral paper strip is the same as that of the second spiral paper strip, and the width of the second spiral paper strip is matched with that of the spiral groove.
