Amapayipi ensimbi aphakathi nendawo alandelayo ngezansi

Ukubamba

Esinye seziphambeko zensimbi, ukusebenza kocwecwe olufana nesibazi somkhiqizo.Ivamise ukuba nolimi, i-block noma i-scaly kanye nokusabalalisa okungajwayelekile.Amasayizi anezibazi, ama-shades asuka ngezansi avame ukufakwa.Isibazi esigoqekayo esiphumela esibazini sibizwa ngokuthi ukugoqa, indawo yokusabalalisa, ukwakheka nosayizi kuyafana kakhulu, kuneziphambeko eziningi esikhumbeni se-oxide ngaphansi.Ingaphezulu lemikhiqizo ye-metallurgical ayikuvumeli ukuba nezibazi.

Indawo emhlophe

Ku-acid leaching yezibonelo eziguquguqukayo kubonise amachashazi amhlophe osayizi abahlukahlukene bokukhubazeka kwangaphakathi.Umumo omhlophe ongajwayelekile, ubushelelezi futhi uphakame kancane, ikakhulukazi engxenyeni emaphakathi yosayizi omkhulu nokuqukethwe kwe-alloy ephezulu okugoqiwe kanye nokufogiwa.Isizathu siwukuthi ukwakheka kwamakhemikhali kokuhlukaniswa okumhlophe okungalingani kanye nokuhlanganisa izakhi ezithile ze-alloying.Akulula ukugqwala ngenxa yokukhubazeka kokucwiliswa kwe-asidi kubonakala njengamachashaza amhlophe kumfanekiso.Indlela yamukelwa ukuvimbela ukucwengwa kwe-leukoplakia, i-argon inyakazisa ukuze izithako ezilinganayo, kusetshenziswa ubuchwepheshe be-ingot casting noma ukulawula izinga lokupholisa ukuvimbela ukuhlaziya uketshezi.

Ipayipi lamination

Ukuhlukaniswa kwesakhiwo kwezinhlangano ezinkulu ezikhona ku-substrate yensimbi, kuyisici sangaphakathi semikhiqizo yokucubungula ipulasitiki yensimbi.Ukuhlukanisa ubuso obuhambisana nendawo yokucubungula, izigaba ze-longitudinal nesiphambano zibonise ukuqhekeka okude, kukhona inani elincane lezinto ezingezona ezensimbi ezifakwe emifantwini nokuhlukaniswa, ukubhubhisa ubuqotho be-substrate yensimbi.I-stratification ibangelwa ukushwabana, ukuqhekeka, amaphutha okucubungula ipulasitiki yebhamuza ngokunwetshwa, ukunwetshwa, kanye nokwakheka kokushisela okuhlulekile.

Ukuqhekeka kwezinwele

Esinye seziphambeko zensimbi, ukusebenza kwemigqa enoboya ebusweni bomkhiqizo.Imifantu emifushane kunemifantu engajulile ngalapho kuginqika khona ehlakazekile noma ngamaqoqo.I-Hairline ingumkhiqizo ovame ukuvumela amaphutha, kodwa ukujula kwawo kufanele kuhambisane nezindinganiso ezifanele.

Ukuma kwebhande

Isici esisodwa ensimbi, insimbi yekhabhoni eshisayo egoqiwe ephansi kusakhiwo se-microstructure, ihlelwa ngokufana eduze nendawo eginqikayo, ukusatshalaliswa okunengqimba kokusanhlamvu kwezinhlamvu ze-ferrite ne-pearlite njengomugqa nje.Lokhu kungenxa yokwenzeka ensimbi ngesikhathi sokupholisa ngemva kokugingqika okushisayo ku-ferrite ngokubeka kuqala kanye nokuhlanganisa okungezona ezensimbi i-dendritic segregation strip esukela ekubunjweni, okuholela ekwakhekeni kwemicu ye-ferrite, imichilo yokuguqulwa kwesigaba se-ferrite phakathi kwe-pearlite, kokubili. izigaba ekusabalaliseni isendlalelo.Ngakho-ke ukuba khona kwesakhiwo sebhande sesakhiwo esingalingani sensimbi kanye nomthelela wezakhiwo zensimbi, ukwakheka kwe-anisotropy, i-ductility ephansi yensimbi, nokunciphisa ukuqina, okuholela ekugobeni okubandayo okungathandeki, ukunyathela izinga le-scrap, ukuguqulwa okulula ngesikhathi ukwelashwa ukushisa kwensimbi imiphumela emibi.

Amaphutha ebusweni

Ensimbi kanye ne-non-ferrous alloy material surface futhi kuthinta ikhwalithi yemikhiqizo yamaphutha ahlukahlukene ngokujwayelekile.Izinhlobo eziningi zokukhubazeka okungaphezulu, ikakhulukazi ku-morphology yesici ukubiza, kanye nezinye zezimbangela zakho eziqanjwe.Izinqubo zokukhiqiza ngokuvamile ukuze kukhiqizwe imikhiqizo enesici ezindaweni ezimbili.Eyodwa ukukhubazeka okubi kwensimbi, njengokuhlukana, izibazi, i-crack, i-hairline, amabhamuza, njll. Iningi lalezi zinkinga libangelwa ikhwalithi ephansi ye-ingot.Elinye iphutha ukusebenza kabi kwemishini, okubandakanya ukugoqa, izindlebe, umgodi, i-convex hull, imihuzuko, ama-dent, acindezelwe esikalini se-oxide, ama-burrs, njll., lezi ziphambeko zikhiqizwa inqubo yepulasitiki plus.

Burr

Okukodwa kokonakala kwendawo yensimbi, okubonakala njengokusikeka okubandayo, iziphetho zensimbi esaha elishisayo azikho noma i-flame cutting burr, lapho amapayipi ashiselwe enensimbi eyeqile.Imikhiqizo yokusika ebandayo incike ebukhulu begebe le-burr eliphakathi kwe-blade.Umkhiqizo ojwayelekile ukuvumela izinga elithile lezinkinga ezikhona;Kodwa ipayipi le-burr elingaphakathi nangaphandle kufanele lisulwe.
