Abstract
The invention discloses a cold-forming seal head heat treatment technology, a cold-forming seal head requires annealing and normalising treatment, annealing temperature is 625+/-25 DEG C, insulation time is 60 minutes, the normalising temperature is 900+/-25 DEG C, and insulation time is 30 minutes. The treatment process has the advantages that stress is eliminated, service life of the seal head is increased, and cost is saved.
Description
Technical field
The invention belongs to seal head heat treatment technology, be specifically related to a kind of cold-forming seal head heat treatment technology.
Background technology
Cold shaping end socket has accurate size and stable quality, and the surface irregularity do not caused because of heating and oxidation, end socket outward appearance is beautiful, in addition, does not worry the Material degradation produced because of heating.Cold shaping processing all can produce certain unrelieved stress and cold work reinforced, and end socket is no exception.During as met erection stress, welding residual stress, the thermal stresses of container, will Stress superposition be produced, and if when being used in the environment of stress corrosion, likely can produce stress corrosion cracking at short notice.If material is carbon steel, under the environment such as nitrate, ammonia, alkaline sodium, crackle can occur, austenitic stainless steel in this way, under the specific environment having chlorion, crackle can occur, this crackle is called stress corrosion cracking.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of cold-forming seal head heat treatment technology is provided, easy to operate.
Cold-forming seal head heat treatment technology provided by the invention, the end socket of cold-forming need carry out annealing and add normalizing treatment, and annealing temperature is 625 ± 25 DEG C, soaking time 60min; Normalizing temperature 900 ± 25 DEG C, soaking time 30min.
Cold-forming seal head heat treatment technology provided by the invention, its beneficial effect is, eliminates stress, and improves the work-ing life of end socket, provides cost savings.
Embodiment
Below in conjunction with an embodiment, cold-forming seal head heat treatment technology provided by the invention is described in detail.
Embodiment
The end socket of cold-forming need carry out annealing and add normalizing treatment, and annealing temperature is 625 ± 25 DEG C, soaking time 60min; Normalizing temperature 900 ± 25 DEG C, soaking time 30min.
