Iityhubhu zeTitanium eziXontekileyo ezisetyenziswa kwiZakhiwo zeZakhiwo

Ityhubhu yeTitanium yenziwe ngee-alloys ze-titanium okanye ze-titanium. Ineempawu ezifana nokuba lula, inamandla aphezulu, kwaye inika ukumelana nokugqwala okuhle kakhulu. Ihambelana nemigangatho efana ne-GB/T3624, GB/T3625, kunye ne-ASTM B337/338, isetyenziswa kakhulu kushishino lweekhemikhali, kwi-aerospace, kubunjineli bezolwandle, kwezonyango, nakwezinye iindawo. Amanqanaba aqhelekileyo aquka uthotho lwe-TA0-TA10, BT1, kunye ne-Gr1-Gr2. La manqanaba ahlulwe ngohlobo lwe-α (uthotho lwe-TA), uhlobo lwe-β (uthotho lwe-TB), kunye nohlobo lwe-α+β (uthotho lwe-TC). Iimpawu zazo zenziwe ngokwezinto ezifana ne-aluminium kunye ne-molybdenum. Ngokukodwa, i-aluminium yonyusa amandla kunye nokumelana nobushushu bezinto.

Inkqubo yokuvelisa iityhubhu zetitanium ibandakanya ubuchwepheshe obufana nokuqengqeleka okubandayo, ukuwelda, kunye nokuphuma. Ububanzi bangaphandle buqala kwi-4mm ukuya kwi-2800mm, apho ukuphambuka kobukhulu bodonga kulawulwa ngaphakathi kwe-±12.5%. Ulwakhiwo lweekhemikhali kufuneka luhambelane nemigangatho yomxholo wokungcola ukuze kugcinwe iplastiki. Uxinano lwayo lumalunga ne-4.51 g/cm³, kwaye amandla ayo okutsalwa anokufikelela ngaphezulu kwe-895 MPa. Ububanzi bobushushu bayo bokusebenza buqala kwi--253°C ukuya kwi-550°C. Iityhubhu zetitanium zisetyenziswa kakhulu kwizicelo ezifana nezixhobo zokutshintshiselana nobushushu (umz., ii-condenser, ii-evaporators), njengeetyhubhu eziqhelekileyo kushishino lwamandla enyukliya, kwiindawo ze-compressor yenjini yeenqwelo-moya, nakwiitanki zokugcina amafutha eenqwelo-moya.

Ezi tyhubhu zihlala zenziwe nge-titanium ecocekileyo yorhwebo (umz., iGrade 1/TA1, iGrade 2/TA2) okanye i-titanium alloys (umz., iTi-6Al-4V/TC4, iTi-3Al-2.5V/TA18). Iimpawu eziphambili zezinto ziquka:

Umlinganiselo oPhakamileyo wamandla ukuya kuxinano: Amandla okuxinana athelekiswa nentsimbi yekhabhoni, enoxinano lwe-4.51 g/cm³ (iphantsi kakhulu kunentsimbi).

Ukumelana Nokugqwala Okungaqhelekanga: Umaleko we-oxide oxineneyo, ozilungisa ngokwawo unika ukumelana okuphezulu kwii-asidi (kuquka i-hydrochloric kunye ne-sulfuric acid), ii-alkalis, kunye nezinye izinto ezihlaselayo.

Iimpawu Ezilungileyo Zokwenziwa: Ukudityaniswa kakuhle, ukusebenza kakuhle nokubanda/ubushushu, kunye nokuqina kobushushu obuphantsi.

Ukusebenza kobushushu obuphezulu: Igcina amandla aphezulu kunye nobunzima ukuya kuthi ga kwi-600°C, kwaye inamandla amahle okuqhekeka kokuqhekeka xa amaqondo obushushu esondela kwi-900°C.

Imveliso ibandakanya amanqanaba amane aphambili:

Ukukhethwa kwezinto eziluhlaza: Iityhubhu ezingqukuva zeTitanium ezingenamthungo okanye ezidityanisiweyo njengezondlo.

Ukwenziwa kweRoll: Ukuqengqeleka okubandayo/okushushu ukuguqula iindawo ezinqamlezileyo ezijikelezayo zibe ziiprofayili eziziingxande.

Unyango lobushushu: Ukufakela i-Annealing ukuze kuphuculwe iipropati zoomatshini kunye nokunciphisa uxinzelelo.

Ukugqitywa komphezulu: Umatshini wokugaya (ukujika, ukupolisha), ukukhupha inkunkuma, kunye novavanyo olungatshabalalisiyo ukuze kususwe iziphene zomphezulu.

Uluhlu oluqhelekileyo lobukhulu luquka:

Ubukhulu bangaphandle: 3 mm ukuya kwi-500 mm (isikwere/unxande)

Ubukhulu bodonga: 0.8 mm ukuya kwi-8 mm

Ubude: ≤ 6000 mm (eqhelekileyo)

Ubukhulu obulungiselelwe wena bufumaneka ngokweemfuno zomthengi.

I-Aerospace: Izakhiwo ze-Airframe, izinto ze-injini

Ubunjineli boLwandle: Iinkqubo zokufaka imibhobho kwiinqanawa, iiyunithi zokukhupha ityuwa emanzini olwandle (ukumelana nokugqwala kwamanzi olwandle)

Iikhemikhali kunye namandla: Ukucubungula i-chlor-alkali, izixhobo ze-petrochemical, izixhobo zokutshintshiselana ubushushu

Ulwakhiwo kunye noomatshini: Izakhelo zesakhiwo, iinkqubo zokufakelwa kwelanga, izixhobo zekreyini

Izixhobo zonyango: Izixhobo zotyando kunye nezinto ezifakelweyo (ezinceda ekuhambelaneni kwezinto eziphilayo)
