Study on Mechanical Properties of Welded Joints of Duplex Insimbi Engagqwali

   Insimbi engenalutho ye-Duplex inesilinganiso esifanayo se-ferrite ne-austenite, futhi inezakhiwo ezinhle kakhulu zemishini nokumelana nokugqwala. It is kabanzi petrochemical, ezokuthutha, ubunjiniyela basolwandle kanye neminye imikhakha. Insimbi engagqwali engu-2205 eyiduplex imele isizukulwane sesibili sensimbi engagqwali, futhi inani lokukhiqizwa komhlaba nokusetshenziswa kwalo kufinyelela kuma-80%. Njengenqubo ebaluleke kakhulu ekucubunguleni izinto ezibonakalayo, i-welding inomthelela omkhulu ekukhiqizeni, ekusetshenzisweni nasekukhuthazeni insimbi engagqwali eyi-duplex.

Kodwa-ke, ngaphansi kwesenzo somjikelezo oshisayo wokushisela ngesikhathi senqubo yokushisela, insimbi eyisisekelo nensimbi efakwe ku-weld kuthambekele ochungechungeni lwezinguquko zesigaba esiyinkimbinkimbi kanye nokufuduka kwezinto ngaphansi kwezimo zokushisa ezingagxilile zokushisa okusheshayo nokupholisa okusheshayo. Inhlangano nokusebenza kukonke kunomthelela omkhulu. Ngakho-ke, inani locwaningo lokucwaninga lokutholakala kwensimbi engagqwali i-duplex ukuqinisekisa ukuthi indawo ethinteke ekushiseni nendawo ye-weld yejoyini elishiselwe ithola isilinganiso esifanele sezigaba ezimbili ngokubeka imingcele yenqubo efanele; ukuvimbela imvula yesigaba sesibili esiyingozi ebangelwa ukushisa kwe-welding nokupholisa Futhi kubangele ukuhlangana.

Ochwepheshe bethu basebenzisa indlela yokucwiliswa kwe-arc okuzenzakalelayo kanye negesi yocingo evikelekile evikela i-arc welding ekushiseleni insimbi engagqwali ye-SAF2205, egxile kumphumela wezinqubo ezahlukahlukene zenqubo yokushisela ku-microstructure nezakhiwo zemishini yamajoyini ashiselwe. amathonya.

Izinto eziyisisekelo ezisetshenziselwe isivivinyo yi-SAF2205 duplex insimbi engagqwali ekhiqizwa inkampani yaseSweden i-Avesta, enobukhulu bepuleti eyi-12mm; okokushisela nakho kunikezwa yinkampani, ibanga locingo olucijile yi-Avesta FCW-2D2205 / Φ1.2mm, futhi ucingo lwe-arc welding wire kanye ne-flux grade yi-Avesta2205 /Φ3.2mm, Avesta Flux805.

UMinghe Inkampani yeDie Casting anikezelwe ekukhiqizeni nasekuhlinzekeni ikhwalithi nokusebenza okuphezulu Izingxenye Zokulingisa (izingxenye zensimbi zensimbi zokufa zisebenza ikakhulukazi zibandakanya I-Thin-Wall Die Casting,I-Hot Chamber Die Casting,Cold Chamber die Casting), Insizakalo Eyindilinga (Insiza Yokulingisa,ICnc Machining,Ukwenza Okubandayo, Surface Treatment) .Noma ikuphi ukusakazwa kwe-Aluminium die, i-magnesium noma i-Zamak / zinc die casting nezinye izidingo zokuphosa zamukelekile ukuxhumana nathi.

Ngaphansi kokulawulwa kwe-ISO9001 ne-TS 16949, Zonke izinqubo zenziwa ngamakhulu emishini esezingeni eliphakeme yokufa, imishini ye-5-axis, nezinye izikhungo, ezisukela kuma-blasters kuya kumishini yokuwasha ye-Ultra Sonic.Minghe akagcinanga ngemishini esezingeni eliphezulu kepha futhi unobuchwepheshe iqembu lonjiniyela abanolwazi, ama-opharetha nabahloli ukwenza ukwakheka kwekhasimende kugcwaliseke.

Umenzi wenkontileka yokufa kwabasikiwe. Amandla afaka izingxenye ezibandayo ze-aluminium die casting ezivela ku-0.15 lbs. kuye ku-6 lbs., Ukusetha ushintsho olusheshayo, nemishini. Izinsizakalo ezingezwe ngenani zifaka phakathi ukupholisha, ukudlidliza, ukuphazamisa, ukuqhumisa ngokudubula, ukupenda, ukuhlobisa, ukumboza, ukuhlangana nokusetshenziswa kwamathuluzi. Izinto zokusebenza ezisetshenzisiwe zifaka ama-alloys afana no-360, 380, 383, no-413.

I-Zinc die casting design usizo / izinsizakalo zobunjiniyela ezihambisanayo. Umenzi wangokwezifiso we-precision zinc die castings. Ukusakazwa okuncane, ukukhishwa kwengcindezi ephezulu, ukusikeka kwesikhunta esiningi, ukujikijelwa kwesikhunta okuvamile, ukufefa kwamayunithi kanye nokuzimela okuzimele kanye nokuvalwa okuvaliwe komgodi kungenziwa. Ama-Castings angenziwa ngobude nobubanzi obufinyelela ku-24 in. Ku +/- 0.0005 in. Ukubekezelelana.  

I-ISO 9001: Umkhiqizi oqinisekisiwe ka-2015 we-die cast magnesium, Amandla afaka i-high-pressure magnesium die casting up to 200 ton chamber hot & 3000 ton cold chamber, designing designing, polishing, molding, machining, powder & liquid paint, QA full with CMM amakhono , inhlangano, ukupakisha nokulethwa.

Kuqinisekiswe i-ITAF16949. Insiza Eyengeziwe Yokulingisa Faka ukukhipha utshalomali,ukuphonsa kwesihlabathi,Ukuphonswa kwamandla, Lost Foam Ekubunjweni,I-Centrifugal Casting,Ukuphoswa Kokuqothula,Permanent Isikhunta Ukulingisa, Amakhono afaka i-EDI, usizo lobunjiniyela, ukumodeliswa okuqinile nokucutshungulwa kwesibili.

Izimboni Zokulingisa Izingxenye Zamacala Ezifundo Zezimoto: Izimoto, Amabhayisikili, Izindiza, Izinsimbi Zomculo, I-Watercraft, Amadivayisi we-Optical, Izinzwa, Amamodeli, Amadivayisi we-elekthronikhi, Ukuvaleka, Amawashi, Imishini, Izinjini, Ifenisha, Ubucwebe, AmaJig, Telecom, Ukukhanyisa, Amadivayisi Wezokwelapha, amadivayisi wezithombe, Amarobhothi, okubaziwe, okokusebenza komsindo, okwezemidlalo, i-Tooling, Amathoyizi nokuningi. 

Yini esingakusiza ukuthi uyenze ngokulandelayo?

Izinqubo ezintathu ezahlukene zokushisela zisetshenziselwe ukwenza izivivinyo zokushisela amapuleti ayizicaba ku-2205 duplex insimbi engagqwali. Ngemuva kokushisela, ukwakheka okuncane kwejoyini kuyabonakala nge-microscope ye-metallurgical ne-SEM. Ingxenyenamba yevolumu ye-austenite inqunywa yindlela yegridi, ebhekisa ku-ASTM E562 ejwayelekile, futhi ukuhlolwa kokusebenza komshini kwenziwa ngokuya ngemithetho ye-China Classification Society "Izinto Zokusebenza Nemithetho Yokushisela".

Ngokuvamile, i-austenite ibamba iqhaza elibalulekile ekuthuthukiseni i-ductility yensimbi engenasici ye-duplex. Ebangeni elithile, amandla wokumunca umthelela walokho okuqukethwe ahlobene kahle nokuqukethwe kwe-austenite. Olunye ucwaningo luthole ukuthi ukuqina komthelela wezinhlanganisela zensimbi engagqwali ye-duplex akuhlobene kuphela nezigaba zayo ezimbili, kepha futhi kuhlobene kakhulu nemvula yezigaba zesekondari eziyingozi. Imvula yenani elincane lesigaba can inganciphisa kakhulu ubunzima bomthelela wento leyo.

Enqubeni yokushisela enezendlalelo eziningi nokuphasa okuningi, ukwelashwa kokushisa kobuhlalu be-weld obulandelayo kuthinta ngqo izinga lokupholisa lensimbi ebekiwe. Lapho inani elikhulu lensimbi lokugcwalisa lilandela futhi ubukhulu be-weld bead, kwehla izinga lokupholisa, elandisa ngokwengeziwe Ithuba lemvula yesigaba se- and nesigaba se- γ2.

Ukwakheka okuncane kwe-duplex insimbi engagqwali eshiselwe amalunga kuqukethe izigaba ezimbili ze-ferrite ne-austenite. Ngaphandle kwenqubo ye-V-groove SAW + FCAW ehlanganisiwe, inani le-austenite ebangeni eliphansi le-weld lesampula elihlangene likhulu kakhulu, amanye amasampula ayi-austenite Ingxenye yomzimba isondele kuleyo yensimbi eyisisekelo, cishe ama-50 %, futhi isilinganiso se-HAZ austenite ngokuvamile siphansi kunaleso sendawo ye-weld.
