Problems solved by technology
Regarding the steel pipe rolled by the plate rolling machine, after long-term research by the inventor, it has been found that steel pipes with a diameter of less than 2 meters will hardly be deformed during the rolling process due to the strength and plasticity of the steel plate itself. When the steel pipe over 2 meters is rolled, the steel plate is usually more than 6 meters in length. After the steel plate is rolled for a certain distance by the plate rolling machine, the rolled part will sink due to its own weight, which will cause serious problems. Large deformation, which leads to difficulty in forming steel pipes and low rolling efficiency

The invention relates to the technical field of steel pipe rolling, and discloses a steel pipe rolling auxiliary tool and a steel pipe rolling method. The steel pipe rolling auxiliary tool comprises a base, a movable adjusting device and a pipeline supporting component; the movable adjusting device is adjustably installed on the base, and the distance between the movable adjusting device and the plate rolling machine can be adjusted according to the diameter of a steel pipe to be rolled; and the movable adjusting device is provided with a plurality of supporting stations, and the pipeline supporting component is adjustably installed in one supporting station so as to provide supporting force for part of steel pipelines rolled by the plate rolling machine. According to the technical scheme, compared with the prior art, when a steel pipe with the diameter exceeding a certain value is rolled by the plate rolling machine, the rolled pipe part can be supported, so that the rolled part is well prevented from deforming, and the steel pipe rolling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of steel pipe rolling, in particular to a steel pipe rolling auxiliary tool and a steel pipe rolling method. Background technique [0002] A steel pipe is a circumferential steel material with a hollow interface. Steel pipes are widely used in pipeline transportation, engineering structures, thermal equipment, petrochemical and other fields. Steel pipe rolling is a common production process for steel companies to prepare steel pipe materials. [0003] The inventors of the present application found in the research that, in the prior art, steel pipes within a certain numerical diameter can be obtained by direct rolling of steel plates, while steel pipes with a diameter exceeding this certain numerical value can only be processed by a coiling machine. system can be prepared. Regarding the steel pipe rolled by the plate rolling machine, after long-term research by the inventor, it has been found that steel pi...
