Description

Technical Field

[0001] The utility model relates to the technical field of flange components, and more specifically to an ultra-large-caliber stainless steel rolling ring forging. Background Art

[0002] Rolled ring forgings are the abbreviation of rolled ring forgings. They are annular metal products manufactured by heating metal billets and rolling them with large rolling mills. Rolled ring forgings have good mechanical properties, good uniformity, good corrosion resistance, etc. Therefore, they are widely used in aerospace, energy, transportation and other fields. Flanges are one of the most common rolled ring forgings.

[0003] Based on the above, the inventors found that the existing large-diameter flanges are mainly used in conjunction with bolts to complete the connection of pipelines, but the connection between the bolts and the flanges is usually directly exposed to the outside. Over time, the connection between the bolts and the flanges is prone to corrosion and rust, thereby affecting the connection stability of the pipelines. Therefore, in view of this, the existing structure is studied and improved to provide an ultra-large-diameter stainless steel rolled ring forging, in order to achieve a more practical purpose.
