Ama-forging amakhulu amahhala kanye nensimbi ephezulu ye-alloy forgings ngokuyinhloko yenziwe nge-ingot yensimbi, engahlukaniswa ibe ingot enkulu kanye ne-ingot encane ngokusho kokucaciswa kwensimbi yensimbi.Ngokuvamile isisindo sikhulu kuno-2t ~ 2.5t, ububanzi bukhulu kuno-500mm ~ 550mm ingot ebizwa ngokuthi i-ingot enkulu, enye ingot encane.

Cindezela i-forging ingot forging esetshenziswa ngaphambi kwezinga lokushisa lesithando sokushisa lapho ukulayisha kuhlukaniswa ama-ingots abandayo (ngokuvamile ngokwezinga lokushisa legumbi) kanye ne-ingot eshisayo (ngokuvamile enkulu kunezinga lokushisa legumbi) kuma-ingots abandayo angaphansi kuka-500 ℃ ipulasitiki yokufudumeza impofu, futhi yakhiwa i-ingot in crystallization process kanye nokucindezeleka okusalayo kanye nesiqondiso sokucindezeleka kokushisa, zonke izinhlobo zokukhubazeka kwezicubu zizobangela ukuhlushwa kokucindezeleka, uma ukucaciswa kokushisa okungalungile, kulula ukubangela ukuqhekeka.Ngakho-ke, esigabeni sokushisa esiphansi sokushisa kwe-ingot ebandayo, izinga lokushisa lokulayisha kanye nesivinini sokushisa kufanele libe nomkhawulo.
I-Forging i-ingot enkulu enezincazelo eziningi zokushisa, ngenxa yobukhulu bayo besigaba esikhulu, phakathi nendawo yokucindezeleka okukhulu kakhulu, kuhlanganiswe namandla e-ingot aphansi, i-plasticity empofu, ngakho-ke ukucindezeleka kokushisa okukhangayo kulula ukuqhekeka lapho kushisa, ngakho-ke, izinga lokushisa lomlilo alikwazi ukuba phezulu kakhulu, isivinini sokushisa kufanele futhi senziwe kancane.Isibonelo, ngensimbi yesakhiwo se-carbon structural steel ne-alloy structural steel, izinga lokushisa lomlilo livamise ukuba ngu-350℃ ~ 850℃, usayizi we-ingot mncane, izinga lokushisa lomlilo likhulu, kanye nokwahlukanisa.Ngensimbi ye-alloy, njengensimbi yesivinini esikhulu, insimbi ephezulu ye-chromium kulula ukuqhekeka lapho ishiswa, izinga lokushisa lomlilo kufanele lilawulwe ku-400 ℃ ~ 650 ℃.Uma izinga lokushisa lingaphezulu kuka-850℃, ingot ingashiswa ngesivinini esisheshayo, kodwa hhayi ngokushesha kakhulu, ukugwema ukwenzeka kokufogina ngaphakathi nangaphandle umehluko wezinga lokushisa mkhulu kakhulu.Isibonelo, ama-forgings ensimbi yesakhiwo se-carbon kanye nensimbi yesakhiwo se-alloy kuvumela umehluko wezinga lokushisa phakathi kuka-50℃ no-100℃.
Lapho ushisa i-ingot yensimbi encane, ngenxa yobukhulu bayo besigaba esincane, ukucindezeleka okusele kanye nokucindezeleka kwezinga lokushisa okubangelwa ukushisa akukukhulu, isivinini sokushisa singashesha, ngakho-ke, ngensimbi ye-carbon cable kanye ne-low alloy steel ingot, ingxenye ye- ngokushesha Ukushisisa kusetshenziselwa ukukhanga.Ukuze uthole ingot yensimbi ene-alloy encane, ngenxa yokushisa kwayo okuphansi kokushisa okushisayo akubi kahle, futhi ukushisa okukhulu kwe-ingot okubandayo, kusebenzisa ukucaciswa kokushisa okunezigaba eziningi, izikhala zokubumba zingafakwa ku-700 ℃ ~ 1000 ℃ esithandweni sokushisa.
Ukuze unciphise isikhathi sokushisa futhi wonge uphethiloli, i-ingot enkulu esuka endaweni yokusebenzela yensimbi ngemva kokukhumula, ithunyelwe ngokuqondile endaweni yokusebenzela yokushisisa isithando somlilo, lolu hlobo lwensimbi olubizwa ngokuthi i-hot ingot.Lapho i-ingot eshisayo ishaja, izinga lokushisa elingaphezulu lika-550 ℃ ~ 650 ℃, ngenxa ye-ingot eshisayo esesimweni esihle sepulasitiki, ukucindezeleka kwezinga lokushisa kuncane, ngakho-ke izinga lokushisa lomlilo lingathuthukiswa, kuye ngokuthi ubukhulu be-ingot nezinto ezibonakalayo zihlukile ibe esithandweni esivamile esingu-800 ℃ ~ 1000 ℃, izinga lokushisa lomlilo elincane le-ingot lingaba elingenamkhawulo, ngemuva kokushaja kungaba yijubane elikhulu kakhulu lokufudumeza.
