Hunhu hwehukama hweAustenitic Stainless Simbi: Iyo elastic uye purasitiki kushushikana uye kushushikana panguva yekuita kwakakura kwazvo, asi matanda anotonhora haawanzoonekwa. Iko hakuna nzvimbo yekudzima uye zviyo zvinogadziriswa muWels, saka simba rakafanana neakarukwa.
Zvinetso zvikuru zveAustenitic Stainless Simbi Welding: Huru Welding deformation; Nekuda kwemuganho wayo wezviyo uye kunzwa kune zvimwe zvinotsvaga zvisingarerisikidzo (s, p), zviri nyore kuburitsa mitsara inopisa.
Zvishanu zvakakura zvekutengesa zvinetso uye matanho ekurapa eAustenitic Stainless Simbi
01 Kuumbwa kweChromium carbide kunoderedza kugona kweWels kuti udzivise kupindirana kuonga.
Kubatanidza Corrostion Corroson: Zvinoenderana nedzidziso yeChromium inodonha pamiganhu yezviyo kana iyo Welt-inokonzerwa nenzvimbo yekudziya yekudziya ye450-850
.
a. Deredza carbon zvemukati yeiyo simbi yesimbi uye weld, uye wedzera kusimbisa zvinhu ti, nb uye zvimwe zvinhu kuimba yesimbi kuti urege kuumbwa kweMC kuti udzivise kuumbwa kweCr23C6.
b. Ita kuti weld weld gadzira chikamu chegumi che-autalenite uye chidiki chidiki cheferrite. Kana paine imwe huwandu hwesimbi muWeld, zviyo zvinogona kunatswa, iyo nzvimbo yezviyo inogona kuwedzerwa, uye yakanyanya kuwanda yechromium carbide pane yeyuniti nzvimbo yemuganhu wetsika inogona kuderedzwa.
Chromium inochema kwazvo muFerrite. Cr23C6 inoumbwa yakaumbwa mune ferrite isina kukonzera austenite zviyo miganhu yekutsetseka mu chromium; Kupararira kwekupererwa pakati peAusteni kunogona kudzivirira kurapwa pamwe chete muganho wezviyo kune iyo mamiriro akasiyana.
c. Dzora nguva yekugara mukunzwa tembiricha yekudziya. Rongedza iyo Telting Thermal kutenderera, kupfupikisa nguva yekugara ye600 ~ 1000】 Zvichanetsa, uye shandisa iyo Plasma Pling Yenyaya yeColly pamusoro nepakati nepakati pakati pemugwagwa multlayer anofanirwa kuveurwa sekupedzisira sezvazvinogona.
d. Mushure mekunge talding, ita mhinduro yekupedza kana kusimbisa kunowedzera (850 ~ 900
(2) banga-rakaumbwa kurongeka kweAlds. Neichi chikonzero, matanho anotevera ekudzivirira anogona kutorwa:
Nekuda kweiyo yakasimba yakasimba kugona kwe kabhoni, ichasarudzika mumiganhu yezviyo kuti iite nyika yakashata panguva yekutonhora, nepo ti uye nb ichiramba iri mukristaro nekuda kwekugona kwakaderera. Kana weld inovhenekwa zvakare mukunzwa tembiricha tembiricha, iyo yakashongedzwa kabhoni ichave yakarongedzwa muchimiro cheCr23c6 pakati pemakristasi.
a. Deredza carbon zvemukati. Yesimbi isina tsvina ine zvinhu zvinosimbisa, izvo carbon zvemukati hazvifanirwe kupfuura 0.06%.
b. Shandisa maitiro anonzwisisika. Sarudza madiki madiki ekupisa yekupisa kuti uderedze nguva yekugara yenzvimbo yakanyanyisa kupisa, uye teerera nekudzivisa mhedzisiro ye 'Evano tembiricha sensitization ' panguva yekuita.
Pakazotungamirwa-miviri-nelting neyekubatana neyekukakavara Kana ikasakwanisa kuitwa, iyo tarisiro yeTlding uye weld chimiro chinofanira kugadziriswa, uye edza kudzivirira nzvimbo yakanyanya kufarirwa mukusangana neyekuchinjika svikiro zvakare inonzwa.
c. Post-weld kupisa kurapwa. Ita mhinduro kana kudzikisira kurapwa mushure mekutora.
02 STRESS CORROPION KUKANGANYA
Matanho anotevera anogona kushandiswa kudzivirira kuitika kwekushushikana kwekunyaradza:
a. Zvakanyatso sarudza zvinhu uye zvine chikonzero chinonyatso kuumbwa. Yakakwirira-yakanyanya chromium-nickel Austenitic Stainless Simbi, yakakwirira-chrromitic simbi, uye welms stenite uye ferrite.
b. Bvisa kana kuderedza kusara kusara. Inogona kushandiswa post-welding kushushikana-kuzadza kupisa kupisa, senge iyo inodzivirira mamiriro ekunze pa-line inopenya kupisa kurapa induction choto inotora nheyo yekuteedzera kupisa. Iyo inovhenekerwa cheni ye Hangocha Tech (Seko Machinery) haidi kutarisisa, zvinongotora masekondi gumi nemashanu kuti uwane kukurumidza kusvika pakudziya kwekunze. Panguva imwecheteyo, ine mhepo yepamusoro yakasimba, iyo inogona kudzivirira zvinobudirira mhepo kumashure panguva yekuwedzera. Iyo yakavezwa yePIPE ine yunifomu yesimbi chimiro uye kushushikana kwekunyepedzera kunova madiki. Uye zvakare, nzira dzekuchina dzakadai sekupukuta, kupfurwa kupfurwa uye zvinomanikidza kunogona kudzikisirawo nzvimbo yakasara yekusara.
c. Dhizaini rakaringana rekugadzira. Kudzivirira kushushikana kukuru kushushikana.
