Umgangatho ophezuluintsimbi ye-aluminiumi-billet yokuvelisa akufanele ibe ne-loose ebalulekileyo, i-porosity, kunye nomxholo ophantsi we-hydrogen kunye nokufakwa kwe-oxidation, i-grain grain. Ukuze kwandiswe ukusasazwa kwamasuntswana esigaba se-diffusion emva kwe-avareji ye-alloy, inkqubo ye-avareji enamanqanaba amabini yobushushu obuphantsi kunye nobushushu obuphezulu bunokwamkelwa. Emva kwe-avareji ye-double-stage, i-dispersion particles kwi-alloy isasazwa ngokulinganayo kwaye ilungile. Amandla aphezulu e-aluminium alloy inoluhlu olubanzi lwe-crystallization kunye nokuthambekela okukhulu kwe-eutectic cracking ngexesha lokuqina okungalinganiyo.
Itekhnoloji yokunyibilikisa i-electromagnetic kukuvelisa amandla e-electromagnetic kwidama elinyibilikisiweyo le-aluminiyam, ukuvuselela umsebenzi we-aluminiyam inyibilika echibini elityhidiweyo, wenze umyinge wokwakheka okunyibilikayo, ukunqanda ukungcoliseka kwezixhobo zentsimbi ngexesha lokuvuselela ngesandla. I-Hydraulic semi-continuous forging machine isetyenziselwa ukukhwabanisa, eneempawu zokusebenza okuzinzileyo, iqondo eliphezulu lokuzenzekelayo kunye nokuchaneka kokulawula okuphezulu. Umsebenzi wokugqibela we-aviation aluminium ingot ihambelana ngokusondeleyo nesakhiwo sayo.
Ke ngoko, akukho crack enkulu ingot forging lucaciso olukhulu lwemveliso yemathiriyeli idinga ukusombulula ukubuyiswa kwehabhu. Ngenxa yokuba i-ingot dimension inkulu, uxinzelelo lobushushu lokufinyela lukhulu, KULULA ukuhlanya. Ukuze wenze ingot enkulu ekhululekileyo enomgangatho ophezulu, uthotho lwetekhnoloji yokunyibilika kunye nokuphosa ziye zaphuhliswa. Nyibilikisa i-electromagnetic eshukumisayo yenye yezona zinto zibalulekileyo itekhnoloji entsha. Ngenxa yomxholo ophezulu wezinto eziphambili kwi-alloy, amandla aphezulu e-aluminium alloy kulula ukuvelisa ulwahlulo kwi-melted, kunzima ukusabalalisa ngokulinganayo, kwaye izinga le-nucleation liyancitshiswa, ubungakanani beenkozo bunzima. Ngelo xesha, i-ingot billet yavavanywa ngokubonwa kwe-ultrasonic flaw for inclusions, ii-cracks, ii-pores kunye nezinye iziphene. Ukongeza kumxholo we-hydrogen, ezinye iintsimbi ze-alkali i-Li, i-Na, i-K kunye ne-alkaline yomhlaba isinyithi i-Ca kufuneka ilawulwe ngokungqongqo.
I-ingot enkulu ebanzi ebanzi kulula ukuyiqhekeza ngexesha lokubumba. Ulawulo oluzinzileyo lwenkqubo yokubumba lubaluleke kakhulu ekwenzeni i-aluminium ingot. Unyango oluqhelekileyo lunokwenza ukubunjwa kwe-alloy kuhanjiswe ngokulinganayo, kuphelise i-non-equilibrium crystallization low melting point, i-spheroidize isigaba sesibini esinzima, senze isigaba sokusasazeka okuhambelanayo ukwenzela ukucubungula okulandelayo ukulawula ukwakheka kweenkozo zezinto, ukunciphisa uvakalelo lokucima i-alloy, ukuphucula amandla kunye nokuqina kwezinto zokulungiswa kwezicubu.
