Ukulungisa inqubo ye-slag inclusion defect of propeller propeller

---

I-propeller yasolwandle ibizwa nangokuthi i-thruster, okuyisisekelo esibalulekile sokuphehla amandla omkhumbi kanye nedivayisi ebalulekile yokuqinisekisa ukuhamba okuphephile komkhumbi. Iziphepheli ezisebenza emanzini olwandle zingaphansi kwemithwalo emikhulu eshintshanayo. Zidinga izakhiwo eziphezulu zemishini, ukumelana nokukhathala okukhulu kokugqwala, kanye nokumelana okuhle kakhulu kwe-cavitation corrosion. Ukukhubazeka okusakaza okufana nama-pores kanye nokufakwa kwe-slag akuvunyelwe.

I-propeller ekhiqizwa yi-PTJ Shop isebenzisa ingxubevange yethusi, esetshenziswa kakhulu ekwenziweni kwe- imishini yokuphehla umshini wemishini yemikhumbi emikhulu neshesha kakhulu. Izinzuzo zayo eziyinhloko isisindo esincane namandla amakhulu. Ukumelana nokukhathala nokumelana nokuguguleka kwe-cavitation kuhle. Ububi bayo yizidingo zokuphonsa nokucubungula eziphakeme. Uma ukufakwa kwe-welding kungamukelwa, izinkinga ezihambisanayo ezifana nokuhlanganiswa okunzima, i-porosity, imifantu eshisayo, kanye nokuguquguquka kwe-welding esezingeni eliphansi lokusebenza ngokuhlanganyela kuzobuyiselwa. . Okulandelayo kuchaza ukusetshenziswa kwe-argon arc welding ukulungisa ukukhubazeka kokufakwa kwe-slag kwesiphepheli.

Incazelo engaphelele

Ububanzi be-crystalline be-alloy yethusi buncane, futhi ukuncipha kwevolumu kukhulu, futhi i-alloy nayo iqukethe izinto ezisebenzayo i-Al, Mn, Fe, Ni, njll, ezinokuhlangana okuqinile kwe-oxygen. Ngesikhathi senqubo yokuthulula, amanzi wethusi asezingeni eliphakeme lokushisa angena kwisikhunta sokususa isanti esilahla ngokunganele futhi ethela uhlelo, futhi inani elikhulu lamanzi wamakhristali asuselwe emanzini akhonjiswe ebusweni besikhunta sokuphonsa ngokushesha ancipha ukuba abe umusi wamanzi. Lapho umhwamuko wamanzi uhlangana nezinto ze-alloy, kukhiqizwa ukufakwa okwenziwe nge-oxidized. I-Slag. Ngaphezu kwengxenye yamaphutha avela ku-0.5R-0.8R engezansi yendawo yensimbi; kukhona nefilimu ye-oxide emboza yonke indawo yesixazululo sethusi ngesikhathi sokuthululelwa, bese isixazululo sethusi singena enkingeni. Kusukela lapho, indawo engaphezulu iqhubekile nokwanda. Kodwa-ke, lapho uketshezi lwethusi lukhuphukela endaweni ephakeme kakhulu yesikhunta sophephela, okungukuthi, onqenqemeni lomhlahlandlela we-0.3R-0.5R, ngenxa yokwehliswa okukhulu kwesigaba esivundlile sensimbi kanye nesiqondisi sokugeleza kuketshezi kophusi kushintshele engxenyeni engenhla igobolondo le-propeller kanye nokukhuphuka, kubangele okwesibili Inani elikhulu lama-oxide slag ahlanganisiwe futhi ukumelana nokukhishwa kuyanda, ukuze inani le-slag yesibili ye-oxide kule ndawo inyuke kakhulu.

Ukukhethwa kwezinto zokushisela

Izinto zokushisela kufanele zikhethwe ngokuya ngezinto zokuphehla ezinokusebenza okufanayo.

Ukulungiselela ngaphambi kokushisela

Sebenzisa isander ukuze ugaye amaphutha futhi ususe ngokuphelele ukukhubazeka kuze kuvele into enhle ye-matrix. Izindawo zokulungisa izinsimbi ezifanele kufanele zicutshungulwe, futhi ama-groove kufanele abe bushelelezi futhi angabi nama-burrs. Bese usebenzisa i-acetone, ibhulashi lensimbi, njll ukuhlanza indawo yokulungisa i-welding namanye omagazini ngaphakathi kwe-20mm ezinhlangothini zombili zamafutha, ama-oxide, umswakama njalonjalo. Yomisa i-electrode ibe ngu-200 ℃ bese uyigcina amahora ayi-1 ~ 2.
Ngenxa yokuhamba okuphezulu kokushisa kwethusi, ukushisa kuyashabalala kalula ngesikhathi sokushisela, ngakho-ke kufanele kufudunyezwe ngaphambi kokushisela. Ngakolunye uhlangothi, ukushisa kuqala kungathuthukisa ukusatshalaliswa kwengcindezi ye-welding futhi kunciphise ubungozi bokuqhekeka kokugqwala kwengcindezi. Izinga lokushisa lokushisa langaphansi kwe-150 ℃. Kungashiswa ngesibhamu somlilo noma ibhande lokushisa kagesi. Ukushisa kwe-interlayer akufanele kweqe ama-300 ℃ futhi kufanele kugcinwe kuze kube sekupheleni kokulungiswa kwe-welding. Ububanzi bokushisa ngaphambi kwendawo yokulungisa i-welding akumele bube ngaphansi kuka-100mm kuzo zonke izinkomba.

Imishini ye-post-weld

Ngenxa yokuthi ama-alloys ethusi azwela kakhulu ekugqobeni kwengcindezi, ukwelashwa kokushisa kufanele kwenziwe ukukhulula ukucindezeleka ngemuva kokushisela. Ukulungiswa kwe-welding encane, ungasebenzisa ibanga legesi elithambile noma i-heater kagesi kagesi ukwenza ukwelashwa kokuxazulula ukucindezeleka kwasendaweni, futhi nokushisa kwasendaweni ukulungisa ukushisela ekushiseni okunezelayo. Amaminithi okulondolozwa kokushisa makhulu kunamamilimitha wobukhulu besigaba kuleyo ndawo, abese embozwa ngendwangu ye-asbestos. kubanda. Ngemuva kokuthi ukwelashwa kokushisa ngemuva kwe-weld sekupholile ngokuphelele, yenza ukuhlolwa kombala kuze kube yilapho imiphumela yokuhlola ingatholi ukukhubazeka okufana nemifantu, ama-pores, njll, futhi ikhwalithi ihlangabezana nezidingo. Ngaphandle kwalokho, ukulungiswa kwe-welding kuyadingeka. Ekugcineni, ukuhlolwa kwe-static balance, ukulinganisa, ukukala kwephimbo, ukulinganisa ubukhulu, ukugaya nokupholisha.
Ukwamukela ukuwelda kwe-argon arc ukulungisa ophephela bemikhumbi nokusebenzisa amapharamitha wenqubo yokushisela enengqondo kungalungisa kangcono ukukhubazeka kohlobo lwe-slag yezihambisi, kuqinisekiswe izakhiwo zomshini ukuhambisa umkhumbi izinto zokwakha, ukwandisa impilo yenkonzo yezihambisi, nokuqinisekisa ukuhamba okuphephile komkhumbi.
