Embonini yokukhiqiza insimbi emhlabeni, ukukhiqizwa kweamashubhu ensimbi angenamthungoidlala indima ebalulekile ezimbonini ezihlukahlukene. Phakathi kwezindlela ezihlukene ezisetshenziswayo, inqubo yokugoqa ebandayo idume ngekhono layo lokukhiqiza amashubhu angenamthungo ekhwalithi ephezulu anobugqi obukhethekile nokuqeda phezulu.
Ngokuphambene nokuginqika okushisayo, ukugoqa okubandayo kuhilela ukuwohloka kwamashubhu ensimbi angenamthungo ekamelweni lokushisa. Inqubo iqala ngokukhethwa kwama-billet amashubhu ensimbi angenamthungo aphezulu, ehlola ngokucophelela noma yikuphi ukukhubazeka noma ukungcola. Lawa mabhilidi ngokuvamile enziwe ngensimbi enekhabhoni ephansi noma ehlanganisiwe futhi angena inqubo yokuhlanza ngokucophelela ukuze asuse noma yikuphi ukungcola okungaphezulu. Uma amabhilidi esehlanziwe, ashiselwa ezingeni lokushisa elifanele, okuwenza athambile. Amabhilidi ashisayo abe esedluliswa ochungechungeni lwezigayo ezigoqayo, lapho egoqwa khona izikhathi eziningana ukuze kuncishiswe ububanzi bawo futhi andise ubude bawo. Le nqubo yenziwa ekamelweni lokushisa, yingakho igama elithi "cold rolling".
Enye yezinzuzo eziyinhloko zenqubo yokugoqa ebandayo yikhono layo lokugcina ubuqotho besakhiwo namandla amashubhu ensimbi engenamthungo. Ngokugwema amazinga okushisa aphezulu, isakhiwo sokusanhlamvu sensimbi sihlala singashintshiwe, ngaleyo ndlela sithuthukise izakhiwo zemishini kanye nokumelana nokugqwala. Ngemuva kokuthi ububanzi bokuqala buncishisiwe, ishubhu lensimbi engenamthungo lidlula uchungechunge lwemithi yokwelapha ukuze kususwe ukucindezeleka kwangaphakathi futhi kucwengisiswe i-microstructure. I-Annealing ibalulekile ukuze kuqinisekiswe ukuthi izici ezifiselekayo zemishini, ezifana ne-ductility kanye nokuqina, ziyatholakala. Ngemva kokuhushulwa, ishubhu lensimbi engenamthungo lidonswa ngokubanda ukuze lilashwe okokugcina. Lokhu kuhilela ukudweba ithubhu ngesikhunta esinobubanzi obuncane, ngaleyo ndlela sinciphise usayizi futhi sithuthukise ukunemba kobukhulu. Ishubhu yensimbi engenamthungo edonsayo iphathwa phezulu, njengokukhetha noma i-phosphating, ukuze isuse noma imaphi ama-oxide noma izikali ezakhayo ngesikhathi sokukhiqiza.
Ukuze kuhlangatshezwane nezidingo ezithile zemboni, amashubhu ensimbi angenamthungo agingqiwe abandayo angabhekana nokwelashwa kwenqubo eyengeziwe, njengokwelashwa kokushisa, ukuhlolwa kwezakhiwo ezisebenza ngomshini noma ukunamathela ukuze kuthuthukiswe ukumelana nokugqwala.
Inqubo yokugoqa ebandayo inezinzuzo eziningi, okuhlanganisa ikhono lokukhiqiza amashubhu ensimbi angenamthungo anokubekezelelana okuqinile, isiphetho esihle kakhulu sendawo namandla aphezulu. Lawa mashubhu asetshenziswa kakhulu ezimbonini zezimoto, i-aerospace, uwoyela negesi, kanye nezimboni zokwakha. Ngokukhula kwesidingo samashubhu ensimbi athembekile futhi ahlala isikhathi eside, inqubo yokugoqa ebandayo ifakazela ukunemba nobuciko bokukhiqiza ishubhu lensimbi engenamthungo. Ngokuqinisekisa ikhwalithi nokusebenza kahle, amashubhu ensimbi engenamthungo agingqiwe abandayo adlala indima ebalulekile ekuqhubekiseni ukuthuthukiswa kwezimboni zomhlaba wonke.
