2026-07-28
Iialloy zeTitanium Zibonakala njengezixhobo zokwakha ezikumgangatho ophezulu ezisetyenziswa kakhulu kwiindawo zesakhiwo seenqwelo-moya, izinto ezifakelweyo kwezonyango, izixhobo zoxinzelelo lweekhemikhali kunye noomatshini bemizi-mveliso abachanekileyo. Zinamandla aphezulu, zichasa ukugqwala ngendlela egqwesileyo, zineempawu zoomatshini ezizinzileyo zobushushu obuphezulu kunye nokuhambelana okugqwesileyo kwezinto eziphilayo, azinakutshintshwa kwimveliso yemizi-mveliso ephezulu. I-Hot forging yinkqubo ephambili yokwenza izinto Izinto zeTitanium ukucubungula, okwakha izinto zokusebenza ze-titanium ezenzelwe wena, okuphucula ulwakhiwo lwangaphakathi lweenkozo, okususa imingxunya kunye neziphene ezibangelwa kukuphosa, kwaye okuphucula ngokupheleleyo uzinzo loomatshini beendawo ze-titanium alloy ezigqityiweyo zenkonzo yexesha elide yemizi-mveliso.
Kwimveliso yokubumba i-titanium yemizi-mveliso, ulawulo oluchanekileyo lobushushu yeyona nto iphambili emisela umgangatho wemveliso egqityiweyo kunye nokuhambelana kwebhetshi. Ubushushu bokubumba ifestile ichaphazela ngokuthe ngqo ukuguquguquka kwe-titanium eshushu, ukukhula kwengqolowa yangaphakathi, inqanaba loxinzelelo olushiyekileyo kunye nokusebenza ngokubanzi kwenkonzo yezinto ezibunjiweyo. Iziphene eziqhelekileyo zokubumba i-titanium ezifana neenkozo ezirhabaxa, ukuqhekeka komphezulu, ukuguquguquka kwesakhiwo okungalinganiyo kunye namandla oomatshini angaguqukiyo, zibangelwa ikakhulu kukuseta ubushushu obungafanelekanga bokubumba. Ngokusekelwe kwimigangatho yemizi-mveliso yamazwe ngamazwe kunye namava eworkshop yokubumba esebenzayo, eli nqaku lazisa ngokucwangcisiweyouluhlu oluphezulu lobushushu bokubumba i-titanium alloy, izinto eziphambili ezinefuthe ekulinganisweni kobushushu, kunye nezikhokelo ezisebenzayo zokulawula inkqubo yabavelisi be-titanium abaziingcali.
1. Indlela Ubushushu Bokubumba Obuchaphazela Ngayo Umgangatho Wokubumba weTitanium
I-Titanium kunye nee-alloys zayo zinobuthathaka obukhulu kubushushu ngexesha leenkqubo zokusebenza ezishushu. Nokuba ukuphambuka okuncinci ukusuka kuluhlu lobushushu oluqhelekileyo lokubumba kuya kubangela utshintsho olungenakuguqulwa kwisakhiwo sangaphakathi, okukhokelela ekuwohlokeni kokusebenza okusisigxina okungenakulungiseka ngonyango lobushushu olulandelayo okanye iinkqubo zokugqiba.
Amaqondo obushushu aphezulu kakhulu abangela ukukhula okungaqhelekanga kweenkozo kunye nokuqobeka okukhulu kweenkozo kwi-titanium matrix. Le microstructure inesiphene inciphisa kakhulu amandla okuxinana, ukuguguleka kunye nobomi bokudinwa, nto leyo eyenza ukuba Izinto zokuLungisa iTitanium Ithambekele ekuqhekekeni kwesakhiwo kunye nokungaphumeleli kwangethuba kwiimeko zenkonzo ephezulu. Ukufudumeza okuhlala ixesha elide kukwakhawulezisa ukufunxwa kweoksijini kunye nehydrogen kumphezulu, okubangela ukuba iileya ze-oxide zibe ngqindilili, ungcoliseko lomphezulu kunye nokuqhekeka kwezinto ezingenakuguqulwa, okonakalisa umgangatho womphezulu kunye nokusebenza ngokupheleleyo kweenxalenye ze-titanium.
Ngokwahlukileyo koko, ubushushu obungonelanga bokubumba bunciphisa kakhulu i-plasticity eshushu yee-alloys ze-titanium kwaye kwandisa uxinzelelo lokuhamba kunye nokumelana nokuguguleka. Ayinyusi nje kuphela umthwalo wee-press zokubumba kwaye ibangele ukwakheka kwe-die okungaphelelanga, kodwa ikwabangela lula ii-microcracks zangaphakathi, izakhiwo ezineengqimba kunye nokuguquguquka okungalinganiyo. Ezi ziphene ezifihlakeleyo zinyusa kakhulu amazinga emveliso e-scrap kwaye zenza buthathaka uzinzo lwexesha elide lwee-forgings ze-titanium ezigqityiweyo.
Ngoko ke, ukukhetha ifestile yobushushu bokubumba echanekileyo, ehambelana nesicelo, sisitshixo sokufumana isakhiwo se-micrograin esifanayo, ukulawula uxinzelelo olushiyekileyo, kunye nokuvelisa ii-forgings ze-titanium alloy zoshishino ezisebenza kakuhle nezisemgangathweni.
2. Izinto eziphambili ezichonga ubushushu bokubumba iTitanium
Akukho bushushu buqhelekileyo obuqhelekileyo bokwenza i-titanium hot forging.

Ubushushu besitofu obuzinzileyo nobulinganayo buthintela iingxaki zokushisa kakhulu okanye ukufudumeza ngaphantsi, ukuqinisekisa ulwakhiwo lwangaphakathi olufanayo kunye nomgangatho ohambelanayo wazo zonke izixhobo zokubumba zetitanium.
4.3 Lawula Ngokungqongqo Ubushushu Bokugqibela Bokubumba
Ubushushu bokugqibela bokubumba kufuneka bulawulwe ngokungqongqo ngaphezu kobushushu obuncinci bokubumba kwakhona be-titanium alloy. Ukuba ubushushu bokugqiba buphantsi kakhulu, izinto azikwazi ukugqiba ukubumba kwakhona ngokupheleleyo, nto leyo eshiya uxinzelelo olukhulu olushiyekileyo ngaphakathi kwento yokusebenza. Oku kuya kubangela ukungalingani kwesakhiwo, ukuphambuka kobukhulu ngexesha lokwenziwa kwe-post-forging, kunye nokusebenza okungazinzanga kwenkonzo yeemveliso ze-titanium zokugqibela.
4.4 Ukubeka iliso kubushushu ngexesha langempela kuyo yonke imveliso
Imigca yemveliso yokwenziwa kwe-titanium yobungcali ixhotyiswe ngee-sensors ze-thermocouple kunye nezixhobo zokulinganisa ubushushu be-infrared zokujonga ubushushu ngexesha langempela. Ukurekhoda idatha rhoqo kunye nokulungiswa kweparameter okuguquguqukayo kuzinzisa ubushushu besithando kunye ne-forging rhythm, okwenza yonke inkqubo yokucubungula ubushushu ichaneke, ilawuleke kwaye ilandeleke.
5. Isiphelo
Akukho bushushu bufanelekileyo obufanayo bonke bokwenza i-titanium alloy hot forging. Eyona festile ifanelekileyo yokucubungula ubushushu imiselwa zizinto ezininzi: umgangatho we-titanium alloy, iimpawu zotshintsho lwesigaba, uyilo lwesakhiwo somsebenzi, ubungakanani bokuguqulwa kwe-forging kunye neemeko zezixhobo zemveliso kwindawo. Ngokubanzi, uluhlu lobushushu olusebenzayo kwimizi-mveliso yokwenza i-titanium yi-700℃ ukuya kwi-1050℃, kunye nolawulo olujolise kwizixhobo ezahlukeneyo ze-titanium olufunekayo.
Ulawulo oluchanekileyo lobushushu kulo lonke Inkqubo Yokwenza iTitaniumUkuphucula kakhulu ukusetyenziswa kwezinto eziluhlaza, kunciphisa amazinga emveliso eentsalela kwaye kucoca ulwakhiwo lwangaphakathi lweenkozo, kuphucula ngokufanelekileyo iipropati zoomatshini kunye nobomi benkonzo yee-titanium alloy forgings. Kwimveliso yanamhlanje yobuninzi bemizi-mveliso, abavelisi kufuneka bayeke ukukopa iiparameter eziqinileyo zethiyori.
