Abstract

The invention discloses a high-quality riffled plate pipe coiling process which is characterized in that a steel plate prepared through IF refining and a titanium plate are subjected to combined machining, a high-strength riffled plate is prepared after flattening, cold embossing and two-end polishing, and then the riffled plate is subjected to secondary rolling and multiple times of finish rolling to prepare a steel pipe; and in the pipe rolling process, the two ends of the two-way shell ring rolling structure are rolled at the same time, left-right balanced rolling is achieved, the riffled plate can be prevented from slightly moving, and the pipe rolling precision is improved. The riffled plate manufactured by the scheme has the advantages of attractive appearance, good stereoscopic impression, high toughness, high strength and the like, defects such as burrs, gaps and bulges of the steel pipe can be effectively eliminated, and the quality of a finished steel pipe product is greatly improved.

Description

technical field [0001] The invention relates to a manufacturing process for coiling steel plates, in particular to a high-quality patterned steel tube coiling process, which belongs to the technical field of steel plate coiling processing. Background technique [0002] The checkered steel plate can not only save a lot of steel and reduce the weight of the structure, but also has good anti-skid and wear resistance. This kind of steel plate is easy to clean and has superior performance, and is suitable for fields such as construction, shipbuilding, transportation and machinery manufacturing. In the production process of checkered steel plates, the coiling mechanism is mainly dedicated to producing various types of coiled tubes and steel pressure steel pipes for annular seams and longitudinal rings, and is improved on the basis of similar specifications and models of traditional coiling equipment. [0003] Patent 201811128175.5 discloses a weather-resistant patterned steel pla...
