Hunhu hwehukama hweAustenitic Stainless Simbi: Iyo Elastic uye Plastic Kushushikana uye Strain panguva yekuita yakanyanya kuwanda, asi kutonhora cracks hazviwanzo kuitika. Iko hakuna Quench kuomesa zone uye zviyo zvinogadziriswa mubatanidzwa wakabatanidzwa, saka simba rakafanana neWeld rakakwira.
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
1. Kuumbwa kweChromium carbide kunoderedza kugona kwemajoini ekuramba kupindira kupindirana kwechipinza.
Kubatanidza Corrostion Corroson: Zvinoenderana nedzidziso yeChromium inodonha pamiganhu yezviyo kana iyo Welt-inokonzerwa nenzvimbo yekudziya yekudziya ye450-850
.
Deredza carbon zvemukati yeiyo simbi uye welds, wedzera kusimbisa zvinhu ti, nb uye zvimwe zvinhu kune simbi yekukasira kupa kukosha kweMC kuti udzivise kuumbwa kweCr23C6.
b. Ita kuti weld weld gadzira chikamu chechidimbu cheAustenite uye chidiki chidiki cheferrite. Kana paine imwe huwandu hwesimbi muWeld, izvo zviyo zvinogona kunatswa, iyo nzvimbo yezviyo inogona kuwedzerwa, uye yakanangana ne chromium carbide pane yuniti nzvimbo ?? iyo muganho wezviyo unogona 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 Welting Thermal kutenderera, kupfupisa nguva yekugara ye600 ℃】 neyekukakavara pakati penzvimbo yehuwandu hwehuwandu hunofanirwa kuveurwa sekupedzisira sezvinobvira.
d. Mushure mekunge talding, ita mhinduro yekupedza kana kusimbisa kuyamadzwa (850 ~ 900 ℃) uye kutonhora kwemhepo kuita kuti vatarisire vatambi vobva vaburitsire chromium).
. Nechikonzero ichi, matanho ekudzivirira anotevera anogona kutorwa:
Nekuda kwekusimba kwakasimba kwekabhoni, iyo ichasarudzika mumigwagwa yezviyo kuti iite nzira yekutonhora, nepo ti uye nb ichiramba iri mukristaro nekuda kweiyo yakaderera kusagadzikana kugona. Pakazotorwa kuunganidzwa zvakare mukunzwa tembiricha tembiricha, carbon carbon ichatsemuka 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 kupisa nguva yekudzikisa nguva yekugara yenzvimbo yakanyanya kuwanda pakupisa, uye teerera nekudzivisa tembiricha ' Pakazotungamirwa-miviri-nelting neyekubatana neyekukakavara Kana ikasakwanisa kuitwa, iyo tarisiro yeTlating uye weld chimiro chinofanira kuchinjirwa kuti udzivise nzvimbo yakanyanyisa kusangana neyekukasira svikiro zvakare inonzwa zvakare.
c. Post-weld kupisa kurapwa. Ita mhinduro kana kudzikisira kurapwa mushure mekutora.
2. STRESS CORRISION CRAING
Matanho anotevera anogona kushandiswa kudzivirira kushushikana kuora kupaza kubva pakuitika:
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. Takura kunze-weld kushushikana kwekununura kupisa kurapwa, uye shandisa nzira dzekuchinjana dzakadai sekupukuta, kupfurwa kupenya uye kuomesera kuderedza nzvimbo yakasara yakasara.
c. Dhizaini rakaringana rekugadzira. Kudzivirira kushushikana kukuru kushushikana.
3. Welding inopisa marara (crystallization marara muWels, liquefiction cracks munzvimbo inopisa-yakakanganiswa.
Kunzwa kwekunzwa kwekupaza kwekupaza zvakanyanya kunoenderana nemakemikari kuumbwa, kurongeka uye kuita kwechinyorwa. Ni iri nyore kuumba yakadzika melting point makomputa kana eutectic neisina tsvina senge s uye p. P. Kureba kweBoron uye silicon ichakurudzira kupaza kwehasha. Weld iri nyore kuumba columnar crystal cryurity ine kutungamira kwakasimba, iyo inokodzera kusevha kwezvinhu zvinokuvadza uye zvinhu. Izvi zvinosimudzira kuumbwa kweiyo inoenderera mberi yekunyepedzera mvura firimu uye inovandudza pfungwa yekunzwa kwekuparadza kwekupaza. Kana iyo testing isina kufanana, zviri nyore kuumba yakakura kushushikana uye kusimudzira chizvarwa chekupisa kupisa marara.
Matanho ekudzivirira:
a. Kudzora zvakanyatso kudzora zvirimo zvekukuvadza kusviba kweS uye P.
B. Gadzirisa chimiro chesimbi yemasuru. Chiverengero cheshuwa chine weld ine yakanaka yekupenga kuramba. Iyo Delta Phase muWeld inogona kunatsa zviyo, Bvisa nzira yeiyo Austenite Shinda mumugove weGijini, uye chidimbu cheDelta chinogona kudzikisira simba uye kuronga kuumbwa kwefirimu rekunyepedzera.
c. Rongedza iyo Weld Simbi Alloy Kuumbwa. Zvakakodzera kuwedzera zvirimo zveMN, C, uye n mune imwechete-phase yeiyo trace's trace
d. Maitiro matanho. Kuderedza kufararira kwedziva rakanyungudutswa kudzivirira kuumbwa kwemakristasi akakora. Shandisa zvidiki zvekupisa kupisa uye chidiki chivharo-chikamu cheld bhead.
Semuenzaniso, 25-20 Austenitic Simbi iri prode kune liquefaction marara. Izvo zvinokwanisika kunyatsogumira kusvibiswa kwezvinhu uye zviyero zvezvinyorwa zvebhokisi, tora yakakwira simba density yelting nzira, diki yekupisa yekuisa uye kuwedzera chiyero chinotonhorera chejoini.
4. Mbambo yeAlded majoini
Kupisa-simba simbi inofanirwa kuve nechokwadi chekuti plasticity yeayo yakavezwa majoini ekudzivirira yakakwirira-tembiricha yembbrittlement; Low-tembiricha inodikanwa kuti uve neakanaka-kupisa-tembiricha yekudziya kudzivisa yakaderera-tembiricha brautlet bracture yeakadzika majoini.
5. Yakakura Welding kukanganisa
Nekuda kwekudzikira kwekunyanyisa kubatana uye kuwedzera kwakakura kuwanda, kusvibiswa kwakakura kwakakura, uye ma clins anogona kushandiswa kudzivirira deformation.
Kana iwe zvakare uine matambudziko ambotaurwa, unogona kuongorora nyaya nekuona pombi yelpe tilding. Wobva watora zviyero zvinowirirana kugadzirisa dambudziko zvichienderana nemamiriro anoenderana. Pamusoro pechinhu chezvinyorwa zvezvinyorwa izvo, chiumbwa, kugoverwa kwemabheya, iyo kumhanya kwazvino, uye iyo yekumhanyisa yePipe yePipe yePipe ichave neyakaoverana kwemhando yeiyo pombi yakavezwa. Se Professional Vagadziri veindasitiri eindasitiri pombi yekugadzira mari yekugadzira , gamuchirwa nekutaurirana NAMAO TECH nezvematambudziko aunosangana nawo mukugadzirwa kweAustenitic Pip matipi, uye tarisira kufambira mberi newe.
