Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, and in particular to a seamless stainless steel gas cylinder heat treatment material frame. Background Technology

[0002] Because stainless steel cannot come into contact with carbon steel, as this will cause carburization, stainless steel must still be selected for heat treatment equipment. Due to its high chromium and nickel content, cast steel 2520 has excellent oxidation resistance and anti-carburization properties, and can form a dense oxide film at high temperatures. It can be used for a long time at high temperatures of 1300℃, and can maintain good shape and performance stability in high-temperature environments.

[0003] Through appropriate heat treatment processes, such as solution heat treatment, the microstructure of stainless steel seamless gas cylinders can be optimized, improving their strength and toughness. This allows the gas cylinders to withstand higher pressures, ensuring safety while reducing their weight and improving their performance and portability.

[0004] Heat treatment can eliminate residual stress in stainless steel, reduce the tendency for stress corrosion cracking, and improve the corrosion resistance of gas cylinders. Simultaneously, appropriate heat treatment can also form a denser oxide film on the stainless steel surface, further enhancing its corrosion resistance and extending the service life of the gas cylinders. The solution heat treatment temperature for seamless stainless steel gas cylinders is 1050℃. Due to the unique structure of the gas cylinders and the lack of a suspension device, the entire heat treatment process is labor-intensive, slow in loading and unloading, and incurs high labor costs. Repeated loading and unloading can also easily cause bumps and scratches, increasing repair workload and scrap rate. Therefore, a suitable heat treatment material frame is crucial for the smooth entry and exit of gas cylinders from the heat treatment furnace during solution heat treatment, placing high demands on material selection and structural design.

[0005] Therefore, there is an urgent need for engineers in this field to develop a stainless steel seamless gas cylinder heat treatment material frame that is simple in structure, easy to use, can effectively prevent stainless steel seamless gas cylinders from tilting during furnace exit, ensure the quality of heat-treated workpieces, and improve furnace exit safety, so as to meet current production needs.
