Izinga lokushisa lokubhoboza insimbi yomthungo oqondile liyahlukahluka ngokuya ngezinto ezingavuthiwe ezixakile. Ipayipi lokunweba elishisayo kodwa ikakhulukazi ku-1200 ℃, lapho okuqukethwe kwekhabhoni nezinye izici ze-alloying izinga lokushisa lingaphansi kancane.

Ukhiye wesibili uwukuzama ukunciphisa inani lesilinganiso sokusebenza kokushisisa. Ikakhulukazi endololwaneni eshisayo yokuxova, ipayipi lensimbi elingu-16Mn eliqondile lisuka ekushiyeni iminyaka yokuphila nekhwalithi yepayipi elixovayo, elinxusa kanzima nakakhulu. Kunqubo yokukhiqiza ipayipi lensimbi engu-16Mn eqondile, njengoba inqubo eyinhloko isesimweni esishisayo, ngakho-ke ukusebenza kokushisa ukuxazulula ikhwalithi yomkhiqizo kuyinqubo ebaluleke kakhulu.

Ukushisa ngesithando somlilo, ngokusho kwemiphumela yabo, futhi isithando somlilo sihlukaniswe izinhlobo ezimbili; eyokuqala isetshenziselwa i-billet eshisiwe ukusuka ekamelweni lokushisa kuya ekushiseni kokucubungula; lokhu kokugcina kusetshenziselwa inqubo ekushiseni okungenalutho kuze kufike ezingeni lokushisa elidingekayo lokucubungula. Ukushisa kuyoba okungalungile endaweni engaphandle ye-tube surface kungase kubonise imifantu, ukugoqa kanye nobuhlungu be-migraine kanye nezinye izizathu zokuchitha. Isithando somlilo Kunezindlela eziningi, kodwa ukusetshenziswa okuyinhloko yisithando somlilo esiyindandatho. Lesi sithando somlilo sineziko le-annular, singashintsha kancane isiqondiso sobubanzi bendawo engenalutho ngaphansi komthwalo kusukela ekungeneni, ukuguqulwa kungasetshenziswa lapho kuphuma ukushisa kanye nezinga lokushisa lokucwiliswa kuhlobo lwesitofu. Lo msebenzi uyisihluthulelo esingenalutho sishisiswe ngokulinganayo kuzinga lokushisa elifanele ukucutshungulwa. Ngoba umthelela omkhulu kwikhwalithi yokubhoboza, okungukuthi, lapho izinga lokushisa lenqubo yokubhoboza kuyisimo esibalulekile esithinta ikhwalithi, ngokuvamile izinga lokushisa lokubhoboza i-billet liwukuxhaphaza.
