Ukuhlaziywa Nokuthuthukiswa Kokukhubazeka Okuvamile Kwama-Valve Castings

 1. IStoma
    Lesi umgodi omncane owakhiwa yigesi engaphunyukanga ngesikhathi senqubo yokuqinisa insimbi. Udonga lwangaphakathi lubushelelezi, luqukethe igesi, futhi lune-reflectivity ephezulu kumagagasi e-ultrasonic, kepha ngoba empeleni luyisiyingi noma i-ellipsoidal, okungukuthi, yisici esime njengephuzu, esithinta ubukhulu be-wave amplitude. Ama-pores akwi-ingot yensimbi abhebhetheka abe nokukhubazeka kwendawo ngemuva kokufaka noma ukugingqa, okunenzuzo ukutholakala ngokuhlolwa kwe-ultrasonic.

     2. Shrinkage kanye porosity

     Lapho ukufakwa noma i-ingot yensimbi kupholile futhi kwaqina, ivolumu izoncipha, futhi ingxenye yokugcina eqinisiwe izokwakha iphutha elingenalutho ngoba ayikwazi ukwengezwa ngensimbi engamanzi. Ama-void amakhulu futhi agxilwe abizwa ngokuthi ama-shrinkage cavities, kanti ama-void amancane futhi ahlakazekile abizwa nge-porosity. Ngokuvamile zitholakala engxenyeni yokugcina eqinile enkabeni ye-ingot yensimbi noma ukusakaza. Udonga lwangaphakathi lurhabaxa futhi luzungezwe ukungcola okuningi nama-pores amancane. Ngenxa yomthetho wokunwetshwa okushisayo nokuncipha, izimbobo zokuncipha zingenakugwenywa, kepha zinezimo ezahlukahlukene, osayizi nezikhundla eziya ngezindlela zokucubungula. Lapho zinwebela emzimbeni wokusakaza noma we-ingot, ziba nezici. Uma ingot yensimbi inganqunywa imbobo yokuncipha futhi ilethwe ekwakheni ngesikhathi sokwakhiwa kwe-billet, kuzoba umgodi osalayo wokuncipha (insali yomgogodla wokuncipha, ishubhu le-shrinkage elisele).

    3. Ukufakwa kwe-Slag

    Ngesikhathi senqubo yokuncibilikisa, i-slag noma into ekhonjiwe esithandweni somlilo iyaxebuka bese ingena ensimbi ewuketshezi, futhi iyabandakanyeka ekubunjweni noma emzimbeni wensimbi ngesikhathi sokuthululelwa, kwakheke iphutha lokufakwa kwe-slag. Ukufakwa kwe-slag imvamisa akutholakali kukodwa, kuvame ukuminyene noma kuhlakazeke ekujuleni okuhlukile. Ziyafana nezici ze-volumetric kepha kaningi zinezinga elithile lobumbano. 4. Ukufakwa

    Imikhiqizo yokuphendula (njengama-oxide, ama-sulfide, njll.) Ngesikhathi senqubo yokuncibilikisa okungafakwanga okusansimbi, noma ezinye izithasiselo ezingxenyeni zensimbi azincibiliki ngokuphelele futhi zihlala zakha ukufakwa kwensimbi, njengokuqina okukhulu, okuphezulu- izingxenye zokuncibilika-iphuzu-i-tungsten, i-Mo njalonjalo.

     5. Ukuhlukaniswa

     Ukwehlukaniswa kokuphonswa noma ama-ingots wensimbi ikakhulu kubhekisa ekuhlukanisweni kokwakheka okwenziwe ngesikhathi senqubo yokuncibilikisa noma inqubo yokuncibilika kwensimbi ngenxa yokusatshalaliswa kokulingana okungalingani. Izici zemishini yendawo ehlukanisiwe zihlukile ezakhiweni zemishini zensimbi yonke, futhi umehluko weqa izinga elivumelekile Ububanzi buba yisici.

     6.Ukusakaza imifantu

     Ukuqhekeka ekusakazweni kubangelwa kakhulu ukuncipha kwensimbi ngesikhathi sokupholisa nokuqiniswa okudlula amandla amakhulu ento leyo. Kuhlobene nokwakheka kokujula kwenqubo yokulingisa, futhi kuyazwela nasekuqhekekeni okubangelwa okuqukethwe okuphezulu kokungcola okuthile kwensimbi. Izici ezihlobene (ngokwesibonelo, ubungqabavu obushisayo lapho okuqukethwe yisibabule kuphakeme, ubulukhuni obubandayo lapho okuqukethwe i-phosphorus kuphezulu, njll.). Ukuqhekeka kwe-Axial intergranular kuzophinda kwenzeke kuma-ingots ensimbi. Uma bengeke bakhiqizwe ekwakheni okulandelayo kwe-billet, bazohlala kuma-forgings futhi babe yimifantu yangaphakathi ku-forgings.

    7. Igumbi elibandayo

    Lesi yisici esiyingqayizivele esigqinsiwe ekusakazweni, okuhlobene ikakhulukazi nenqubo yokusakaza yenqubo yokusakaza. Kubangelwa ukucwebezela, ukuwa, ukuphazanyiswa kokuthelwa, noma imicu emibili (noma imicu eminingi evela ezinkomba ezihlukile) lapho uthela insimbi engamanzi. Ukugeleza kwensimbi kuhlangana nezinye izizathu, ngoba ifilimu elincane eliqinile elenziwa ukupholisa ubuso bensimbi engamanzi lihlala emzimbeni wokuphonsa futhi lenze indawo enjenge-diaphragm.

    8. Flip isikhumba

    Yilapho-ke ingot yensimbi ithelwa khona kusuka endle kuya kusikhunta se-ingot ngesikhathi sokwenza insimbi. Ngenxa yokuphazamiseka nokumiswa kokuthululwa, ubuso bensimbi engamanzi obuthelwe emoyeni buhlile ngokushesha ukwenza ifilimu ye-oxide. Lapho ukuthululwa kuqhubeka, insimbi ewuketshezi esanda kuthululwa izoyisusa. Iphutha le-delamination (indawo) elenziwe ngokugqobhoza futhi liphendukele emzimbeni wensimbi, alikwazi ukuqedwa ngokufaka ekwakheni okulandelayo kwe-billet kwe-ingot yensimbi.

     9. I-Anisotropy

     Lapho ama-castings noma ama-ingots ensimbi esepholile futhi eqinisiwe, izinga lokupholisa kusuka ebusweni kuye enkabeni lihlukile, kwakheka izakhiwo ezahlukahlukene zamakristalu, ezibonakaliswa ekungangeni kobuso bezinto ezenziwa ngomshini, okuholela nasekutholakaleni kwezakhiwo ze-acoustic, ukuthi is, from the center to the center. Ubuso bunejubane elihlukile lokuncishiswa kwemisindo nomsindo. Ukuba khona kwale anisotropy kuzothinta kabi usayizi nendawo yokukhubazeka ngesikhathi sokuhlolwa kwe-ultrasonic kwe-castings.

3. Izindlela zokwenza ngcono

    (1) Imishini yokuncibilika inekhono elibi lokuqinisekisa ukwakheka kwensimbi encibilikisiwe nokuzinza kwemishini yokuxuba isihlabathi akukuhle. Ukwakheka kwensimbi encibilikisiwe kuvinjelwe yizinto eziningi ezifana ne-coke, uhlobo lwesithando somlilo, ivolumu yomoya, nezimo zempahla eluhlaza; Isihlabathi se-resin sithinteka yizinto ezifana nokushisa, i-resin ne-acid kwalokho.
