I-forgings enkulu yamahhala kunye ne-alloy high forgings yensimbi yenziwe ngokukodwa nge-ingot yensimbi, enokuthi ihlulwe ibe yi-ingot enkulu kunye ne-ingot encinci ngokwenkcazo ye-ingot yensimbi. Ngokubanzi ubunzima bukhulu kuno-2t ~ 2.5t, ubukhulu bukhulu kuno-500mm ~ 550mm ingot ebizwa ngokuba yi-ingot enkulu, enye yi-ingot encinci.

Cinezela ukubumba ingot esetyenzisiweyo phambi kobushushu beziko lokufudumeza xa kulayishwa kuhlulwe ngokwee-ingots ezibandayo (ubushushu begumbi ngokubanzi) kunye ne-ingot eshushu (ngokubanzi kunobushushu begumbi) kwiingots ezibandayo ezingaphantsi kwama-500 ℃ iplastiki yokufudumeza ihlwempuzekile, kwaye yenziwe ngu i-ingot kwinkqubo ye-crystallization kunye noxinzelelo olushiyekileyo kunye nolwalathiso loxinzelelo lweqondo lokushisa, zonke iintlobo zeziphene ze-tissue ziya kubangela ukuxinzezeleka koxinzelelo, ukuba inkcazo yokufudumala engafanelekanga, kulula ukubangela ukuqhekeka. Ngoko ke, kwinqanaba eliphantsi lobushushu bokufudumala kwe-ingot ebandayo, ubushushu bokulayisha kunye nesantya sokufudumala kufuneka kukhawulelwe.
Ukufudumeza i-ingot enkulu kunye neenkcukacha ezininzi zokufudumeza, ngenxa yobukhulu becandelo elikhulu, embindini woxinzelelo lwe-tensile inkulu kakhulu, idityaniswa namandla e-ingot aphantsi, iplastiki engalunganga, ngoko ke uxinzelelo lobushushu bokwenza kulula ukuqhekeka xa ufudumeza, ke ngoko, iqondo lokushisa lomlilo alikwazi ukuba phezulu kakhulu, isantya sokufudumeza kufuneka siqhutywe ngokucothayo. Umzekelo, kwintsimbi ye-carbon structural kunye ne-alloy structural steel, ubushushu beziko ngokuqhelekileyo buyi-350 ℃ ~ 850 ℃, ubungakanani be-ingot buncinci, ubushushu beziko bukhulu, kunye nokugquma. Kwinsimbi ye-alloy, njengentsimbi yesantya esiphezulu, intsimbi ephezulu ye-chromium kulula ukuyiqhekeza xa ishushu, ubushushu bomlilo kufuneka ilawulwe kwi-400 ℃ ~ 650 ℃. Xa iqondo lobushushu lingaphezulu kwe-850℃, i-ingot inokufudunyezwa ngesantya esikhawulezayo, kodwa ingakhawulezi kakhulu, ukunqanda ukwenzeka kokufogina ngaphakathi nangaphandle umahluko wobushushu mkhulu kakhulu. Umzekelo, ukufakwa kwentsimbi ye-carbon structural iron kunye ne-alloy structural steel ivumela umahluko wobushushu phakathi kwe-50℃ kunye ne-100℃.
Xa ufudumeza i-ingot yensimbi encinci, ngenxa yobukhulu bayo becandelo elincinci, uxinzelelo olushiyekileyo kunye noxinzelelo lweqondo lokushisa olubangelwa ukufudumeza alukho lukhulu, isantya sokufudumeza sinokukhawuleza, ngoko ke, i-carbon cable steel kunye ne-alloy iron ingot ephantsi, icandelo elikhawulezayo. ingcaciso yokufudumeza isetyenziswa ekwenzeni. Kwi-ingot yentsimbi ye-alloy encinci, ngenxa yobushushu obuphantsi be-thermal conductivity ihlwempuzekile, kunye nokufudumeza kwe-ingot enkulu ebandayo, iphinda isebenzise imilinganiselo yokufudumeza yamanqanaba amaninzi, izikhala zokubumba zingafakelwa kwi-700 ℃ ~ 1000 ℃ eziko lobushushu.
Ukuze unciphise ixesha lokufudumeza kunye nokugcina i-fuel, i-ingot enkulu evela kwi-workshop yentsimbi emva kokuhluthwa, ithunyelwe ngokuthe ngqo kwi-workshop yokufudumeza isithando somlilo, olu hlobo lwensimbi ebizwa ngokuba yi-ingot eshushu. Xa i-ingot eshushu itshaja, ubushushu bomphezulu we-550 ℃ ~ 650 ℃, ngenxa ye-ingot eshushu kwimo yeplastiki elungileyo, uxinzelelo lobushushu luncinci, ngoko ubushushu beziko linokuphuculwa, ngokuxhomekeke kubungakanani be-ingot kunye nezinto ezahlukeneyo, ziyakwazi. ibe kwisiqhelo 800 ℃ ~ 1000 ℃ eziko, iqondo lobushushu ingot encinane ingot ingabinamda, emva ukutshaja inokuba yenye isantya sikhulu zokufudumeza.
