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 yekristallisation kunye noxinzelelo olushiyekileyo kunye nesikhokelo soxinzelelo lobushushu, zonke iintlobo zeziphene zezicubu ziya kubangela uxinzelelo, ukuba ukufudumeza okungalunganga. iinkcukacha, 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 encinci ye-alloy, ngenxa yobushushu obuphantsi be-thermal conductivity ihlwempuzekileyo, 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 ngokuqhelekileyo kwi-800 ℃ ~ 1000 ℃ eziko, iqondo lobushushu elincinci le-ingot engenamkhawulo, emva kokutshaja inokuba yenye yesantya esikhulu sokufudumeza.
