Emva kweityhubhu yesikwerexa ishushu, kuya kuvela umaleko wesikhumba se-oxide emnyama, nto leyo eya kuchaphazela inkangeleko. Okulandelayo, siza kuchaza ngokweenkcukacha indlela yokususa ulusu lwe-oxide kwityhubhu yesikwere enobubanzi obukhulu.
Isinyibilikisi kunye ne-emulsion zisetyenziselwa ukucoca umphezuluumbhobho wesikwere omkhulu nobukhuluukususa ioyile, igrisi, uthuli, i-lubricant kunye nezinye izinto eziphilayo ezifanayo. Nangona kunjalo, ayinakususa umhlwa, isikali se-oxide kunye ne-flux kumphezulu wombhobho wesikwere omkhulu, ngoko ke isetyenziswa kuphela njengesixhobo sokuncedisa ekusebenzeni kokulwa nokugqwala.
Ngokubanzi, iindlela zeekhemikhali kunye ne-electrolytic zisetyenziselwa unyango lwe-pickling. Kusetyenziswa i-pickling yekhemikhali kuphela kwi-anticorrosion yepayipi, enokususa isikali se-oxide, umhlwa kunye nopende oludala. Ngamanye amaxesha, ingasetyenziswa njengendlela yokuhlaziya kwakhona emva kokuqhumisa isanti. Nangona ukucoca iikhemikhali kunokwenza umphezulu ufikelele kwinqanaba elithile lokucoceka kunye noburhabaxa, ipateni yayo ye-anchor ayinzulu kwaye kulula ukubangela ungcoliseko kwindawo engqongileyo. Iipayipi zesikwere ezinkulu ezinobubanzi obukhulu kufuneka zingeniswe ukuze zamkelwe ngeebhetshi, kwaye imigaqo yebhetshi kufuneka ihambelane nemigaqo yemigangatho yemveliso ehambelanayo.
Izinto zokuhlola, ubungakanani besampulu, iindawo zokuthatha iisampulu kunye neendlela zokuvavanya iipayipi zesikwere ezinkulu ezinobubanzi obukhulu kufuneka zihambelane nemigaqo yemigangatho yemveliso ehambelanayo. Ngemvume yomenzi wesicelo, i-hot-rollediityhubhu zesikwere ezinkulu ezinobubanzi obukhuluingathathwa iisampulu ngokweebhetshi ngokwamaqela eengcambu ezigoqiweyo.
Ukuba iziphumo zovavanyo lweetyhubhu zesikwere ezinkulu aziphumeleli ukuhlangabezana neemfuno zemigangatho yemveliso, ezo zingafanelekanga ziya kukhethwa, kwaye inani eliphindwe kabini leesampuli liya kuthathwa kwibhetshi efanayo yeetyhubhu zesikwere ezinkulu ukuze kuhlolwe kwakhona izinto ezingafanelekanga. Ukuba iziphumo zovavanyo kwakhona (kuquka naluphi na uphawu olufunekayo kuvavanyo lweprojekthi) azifanelekanga, ibhetshi yeetyhubhu zesikwere ezinkulu aziyi kuhanjiswa. Ukuba ezi zinto zilandelayo zovavanyo aziphumeleli kuvavanyo lokuqala, uvavanyo kwakhona aluvumelekanga: a Kukho amabala amhlophe kwithishu ye-macroploid; b. Ulwakhiwo lweMicrostructure.
