Technical Field

[0001] This utility model relates to the field of seamless gas cylinder processing technology, specifically a heat treatment fixture for seamless steel gas cylinders. Background Technology

[0002] Seamless gas cylinders are pressure vessels without welded joints, manufactured through processes such as integral forging and extrusion. With their strong structural integrity and stable pressure-bearing capacity, they are widely used in industrial gas storage, medical oxygen transportation, and other fields. Heat treatment is a crucial process to ensure the mechanical properties of seamless gas cylinders. Through processes such as heating, holding, and cooling, internal stresses generated during cylinder forming can be eliminated, the metallographic structure of the material can be optimized, and its fatigue resistance and toughness can be improved, ensuring safe use. Existing fixtures for heat treatment of seamless gas cylinders, after positioning and supporting the cylinders, make it difficult to easily rotate them to adjust their circumferential position. This makes the uniformity of heating of the cylinders easily affected and hinders operators from observing or handling different circumferential parts of the cylinders, thus limiting the heat treatment effect and operational efficiency to some extent.
