Impembelelo yobushushu bokufudumala kunye nexesha lokufakelwa kwi-forging process of ingots zetsimbi. Ukushisa okufudumeza kunye nexesha lokugquma zimbini iiparameters eziphambili kwinkqubo yokuqulunqa iingots zetsimbi, ezichaphazela ngokuthe ngqo iplastiki ye-blank kunye nomgangatho wemveliso yokugqibela. Xa ukhetha ubushushu obufanelekileyo bokufudumala, kuyimfuneko ukuqwalasela ukubunjwa kweekhemikhali zentsimbi kunye neemfuno zenkqubo yokubumba.
Okokuqala, makhe sizuze ukuqonda okunzulu malunga nefuthe lobushushu bobushushu kwii-ingots zentsimbi. Ukufudumeza okugqithisileyo kunokubangela ukuba iinkozo ezingaphakathi kwi-ingot yentsimbi zikhule ngokukhawuleza, ngaloo ndlela zinciphisa iplastiki yezinto. Ngakolunye uhlangothi, ukuba ubushushu bokufudumala buphantsi kakhulu, kunokukhokelela ekufudumeni okwaneleyo, okukhokelela ekuhanjisweni kobushushu obungalinganiyo be-ingot yensimbi kwaye ngaloo ndlela kuchaphazela umgangatho we-forgings. Ke ngoko, ukukhetha ubushushu obufanelekileyo bokufudumeza kubalulekile ukuqinisekisa ukuba ingot yentsimbi ifikelela kwiplastiki efunekayo.
Ngokwencwadi yokubumba, ubushushu bokwenza ii-ingots zentsimbi kufuneka bube phakathi kwe-1150 kunye ne-1270 ℃. Nangona kunjalo, kwiimeko apho umlinganiselo wokubunjwa ungaphantsi kwe-1.5, ulungelelwaniso oluhambelanayo kufuneka lwenziwe. Ngokomzekelo, kwimigangatho yentsimbi eqhelekileyo, ubushushu bokufudumala obucetyiswayo ngu-1050 ℃ xa umlinganiselo wokubumba ngu-1.5-1.3. Kwiimeko apho umlinganiselo wokubunjwa ungaphantsi kwe-1.3 okanye akukho mlinganiso wokubumba ekuhlaleni, kuyacetyiswa ukuba unciphise ubushushu bokufudumala ukuya kwi-950 ℃.
Ukongeza kwiqondo lokushisa lokufudumala, ixesha lokugquma likwayenye yeeparitha eziphambili ezichaza iplastiki kunye nokushisa okufanayo kweengots zetsimbi. Ubude bexesha le-insulation lichaphazela ngokuthe ngqo ukuba inxalenye ephakathi ye-ingot yensimbi inokufikelela kwiqondo lokushisa lokubumba kwaye iqinisekise ukufana kokusabalalisa ukushisa kwiindawo ezahlukeneyo. Ixesha elide lokufakwa kwe-insulation ngokuthe ngcembe lingenza i-homogenize iqondo lokushisa langaphakathi le-ingot yensimbi, ngaloo ndlela iphucula iplastiki ye-ingot kunye nokunciphisa ukuguqulwa kunye neziphene zokubumba. Ke ngoko, xa kuyilwa iinkqubo zokubumba, kuyimfuneko ukumisela ngokufanelekileyo ixesha lokugquma ukuze lihlangabezane neemfuno zokwenziwa kunye nemigangatho yomgangatho.
Isishwankathelo, ubushushu bokufudumala kunye nexesha lokubamba ziyimilinganiselo ebaluleke kakhulu kwinkqubo yokuqulunqa iingots zetsimbi. Ngokukhetha ubushushu obufanelekileyo bokufudumala kunye nexesha elifanelekileyo lokufakelwa, kunokuqinisekisa ukuba i-ingot yensimbi ifumana ngokupheleleyo iplastiki efunekayo kwaye iqinisekise ukufana kweqondo lokushisa kwiindawo ezahlukeneyo. Ngoko ke, kwii-ingots ezinkulu zetsimbi, kukulungele ukwenza ukutshaja kwe-ingot eshushu emva kokudiliza ukuphepha ukwandiswa kweziphene zangaphakathi kunye nomngcipheko we-ingot fracture ebangelwa ukunyanzeliswa kwe-thermal kunye nesakhiwo eyenziwa xa ipholile kwiqondo lokushisa.
