Ukungcola okuyingozi kakhulu kuithusi lensimbikukhona i-aluminium, i-silicon ne-magnesium.Uma okuqukethwe kwabo kudlula i-0.005%, ukufakwa kwe-SiO2, MgO kanye ne-Al2O3 okubangelwa yi-oxide kuzongcolisa ukuncibilika futhi kunciphise ukusebenza kwezinye izici ze-alloy.
Lapho kuncibilikiswa ithusi likathayela, njengoba indawo yokubilisa ye-zinc iphansi ngokuqhathaniswa futhi inokuhlangana okukhulu nomoya-mpilo, ukuncibilika kufanele kukhishwe i-oxidized bese kufakwe esithandweni ukuze kuncibilike.Ipuleti lethusi le-Chuangrui lingakwazi ukwengeza i-deoxidation, okuwusizo kakhulu ukugwema Ingozi yokukhiqiza i-SnO2.I-zinc kanye ne-phosphorus ekuncibilikeni kunesakhiwo esibanzi se-deoxidation, futhi umphumela we-2ZnO·P2O5 kulula ukuwuhlukanisa nokuncibilika, futhi kuyazuzisa ukuthuthukisa uketshezi lokuncibilika.
Ukusebenzisa ishaja eyomile, noma ngisho nokushisa ishaja kuqala ngaphambi kokuncibilika, kunganciphisa noma kugweme ukumuncwa kwegesi ngokuncibilika.Izilinganiso ezifanele zensimbi entsha kanye nemfucuza ecutshungulwa nakho kunomthelela ekuncibilikeni kwekhwalithi ezinzile.Inani lemfucuza yenqubo akufanele lidlule ku-20% kuya ku-30%.Ukuncibilika okungcoliswe kancane ukungcola kungenziwa nge-oxyd ngokufutha umoya noma ngokwengeza i-oxidant (isb. i-copper oxide CuO).Izinsalela ezingcoliswe kakhulu izakhi ezithile zokungcola zingacwengwa ngegesi encibilikayo noma engasebenzi, okuhlanganisa ukuncibilika kabusha, ukuze kuthuthukiswe ikhwalithi yayo.
Ukuphakela kanye nokuncibilika okufanelekile okulandelanayo, okuhlanganisa ukuncibilika ngesithando somlilo se-iron-core induction yamandla-frequency enamandla esinokuncibilika okuqinile, kunenzuzo ekudambiseni nasekugwemeni ukuhlukaniswa.Ukwengeza inani elifanele le-nickel ekuncibilikeni kulungele ukusheshisa ukuqiniswa kanye nesivinini sokucwebezela kokuncibilika, futhi kunomthelela othile ekunciphiseni nasekugwemeni ukuhlukaniswa.Izithasiselo ezifanayo, i-zirconium ne-lithium nazo zingakhethwa.Indlela exubile yokuncibilika yokuncibilikisa ngokuhlukana ingxubevange yethusi umthofu bese ujova ukuncibilika komthofu ekuncibilikeni kwethusi ku-1150-1180°C kungatholwa.Ngaphansi kwezimo ezijwayelekile, ithusi elincibilikisayo eliqukethe i-phosphorus livalwa kakhulu ngezinto ze-carbonaceous ezifana namalahle noma i-petroleum coke ngaphandle kwe-solvent.Isembozo esisetshenziswa uma kuncibilikiswa ithusi likathayela eliqukethe i-zinc kufanele futhi lifake izinto eziqukethe ikhabhoni njengamalahle.Ngesikhathi sokusakazwa okuqhubekayo, kufanelekile ukulawula izinga lokushisa elithephayo ku-100-150 ° C ngaphezu kwe-alloy liquidus.
