Iko Kushandiswa kweTitanium Alloy muIndasitiri yeValve
Titanium alloy ine zvakawanda zvakanaka senge low density, kusimba kwepamusoro, corrosion resistance, tembiricha yakanyanya uye kushomeka kwekushisa, uye inogona kushandiswa zvakanyanya munzvimbo dzakawanda dzakadai sepetroleum, indasitiri yemakemikari, nharaunda yemugungwa, biomedicine, aerospace, indasitiri yemotokari, uye ngarava. . Cast titanium alloy inowanikwa nekukandira titanium alloy muchimiro chaunoda, pakati payo ZTC4 (Ti-6Al-4V) alloy ndiyo inonyanya kushandiswa, ine yakagadzikana mashandiro anoita, simba rakanaka uye kutsemuka kuomarara (pasi pe350 ℃).
Sezvo chikamu chikuru chekutonga kwezvakasiyana-siyana zvakatipoteredza uye yakakosha fluid yepakati pombi yekufambisa masisitimu, mavharuvhu ave chinhu chakakosha chemidziyo yakawanda mukugadzira, uye zvinogona kutaurwa kuti chero indasitiri haigone kuita pasina mavharuvhu. Nekuda kwezvakasiyana kwezvakatipoteredza, tembiricha, uye zvepakati zvinodiwa muminda dzakasiyana, kusarudzwa kwezvinhu zvevharuvhu kwakakosha uye kunokosheswa zvakanyanya. Mavharuvhu akavakirwa patitanium alloys uye akakandwa titanium alloys ane tarisiro yakakura mumunda wemavharuvhu nekuda kwekusagadzikana kwavo kwecorrosion, kuita kwekushisa kwepamusoro uye kwakaderera, uye simba rakakura.
Applications
- Marine
Mamiriro ekushanda epombi yemvura yegungwa ane hukasha hwakanyanya, uye kushanda kwemavharuvhu emugungwa kunobata zvakananga kuchengetedzeka uye kuita kwese kwepombi system. Kare kumakore ekuma1960, Russia yakatanga tsvakurudzo pamusoro petitanium alloys yengarava uye yakazogadzira kuti ishandiswe mugungwa β Titanium alloy inoshandiswa zvakanyanya muhurongwa hwemapaipi engarava, kusanganisira mavharuvhu, mavharuvhu echeki, nemavharuvhu ebhora, ane marudzi akasiyana-siyana. uye nhamba huru yezvikumbiro; Panguva imwecheteyo, mavharuvhu etitanium akashandiswawo muhurongwa hwemapaipi engarava. Kuenzaniswa neyakashandiswa kare alloys yemhangura, simbi, nezvimwewo, kwakatevera kuedzwa kwemvura kwakaratidzawo kuti kushandiswa kweakakandirwa titanium alloys kune kuvimbika kwakanyanya mune zvakawanda zvinhu zvakaita sesimba rekuvaka uye kusagadzikana kwekuora, uye hupenyu hwesevhisi hwakawedzerwa zvakanyanya, kubva. makore ekutanga 2-5 kusvika kanopfuura kaviri, izvo zvakwezva kutarisisa kwakapararira kubva kune wese. Iwo matatu eccentric butterfly valve akapihwa neChina Shipbuilding 725 Research Institute muLuoyang, China kune imwe modhi yengarava shanduko mune yakapfuura kusarudzwa kwezvinhu uye dhizaini chirongwa, vachishandisa Ti80 nezvimwe zvinhu semuviri mukuru, kuwedzera hupenyu hwesevhisi. vharafu kusvika kune anopfuura makore makumi maviri nemashanu, kuvandudza kuvimbika uye kushanda kwevharuvhu chigadzirwa maapplication, uye kuzadza iyo tekinoroji gap muChina.
- Aerospace
Mumunda weaerospace, cast titanium alloys inoitawo zvakanaka, nekuda kwekunaka kwavo kupisa uye simba. Paive zvakare muma1960 apo American Airlines yakatanga kuedza titanium castings. Mushure menguva yekutsvakurudza, titanium alloy castings yakashandiswa zviri pamutemo mundege kubvira 1972 (Boeing 757, 767, uye 777, nezvimwewo). Haisi chete ine nhamba huru ye static chimiro titanium alloy castings yakashandiswa, asi yakashandiswawo munzvimbo dzakakosha, sekutonga kwevharuvhu mune dzakakosha pombi masisitimu. Mavharuvhu anowanzo shandiswa anosanganisira mavharuvhu ekuchengetedza, mavharuvhu ekutarisa, nezvimwewo, izvo zvakaderedza mitengo yekugadzira ndege uye kuwedzera kuchengetedzwa uye kuvimbika, Zvichakadaro, nekuda kwehuremu hudiki uye huremu hwetitanium alloy kana ichienzaniswa nemamwe alloys, inongosvika 60% chete. simbi imwechete yakasimba, kushandiswa kwayo kwakapararira kunogona kusimudzira ndege kuti dzifambe zvishoma kune simba repamusoro uye kutungamira kwakareruka. Parizvino, mavharuvhu emuchadenga anonyanya kushandiswa mune dzakawanda kudzora masisitimu akadai sepneumatic, hydraulic, mafuta, uye lubrication, uye akakodzera zvakanyanya kune nharaunda ine ngura kuramba uye yakakwirira tembiricha kwezvakatipoteredza. Icho chimwe chezvinhu zvakakosha zveaerospace mota, injini, uye mamwe madhipatimendi. Mavharuvhu echinyakare anowanzoda kuchinjwa kwechikamu, uye anogona kusatombozadzisa zvinodiwa. Panguva imwecheteyo, nekuwedzera nekukurumidza kwemusika weaerospace valve, titanium mavharuvhu ari kutorawo chikamu chinowedzera nekuda kwekuita kwavo kwepamusoro.
- Chemical Indasitiri
Makemikari mavharuvhu anowanzo shandiswa munzvimbo dzakaomarara senge tembiricha yakakwira, kudzvanywa kwepamusoro, corrosion resistance, uye musiyano mukuru wekumanikidza. Naizvozvo, kusarudzwa kwezvinhu zvakakodzera kwakakosha pakushandiswa kweindasitiri yemakemikari evharuvhu. Muchikamu chekutanga, kabhoni simbi, simbi isina tsvina, uye zvimwe zvinhu zvinonyanya kusarudzwa, uye ngura inogona kuitika mushure mekushandiswa, inoda kutsiviwa uye kugadzirisa. Nekuenderera mberi kwekuvandudza tekinoroji yetitanium alloy tekinoroji uye kushanda kwayo kwepamusoro kuri kuwanikwa zvishoma nezvishoma, mavharuvhu etitanium akaonekwawo mumaziso evanhu. Kutora chikamu chekugadzira cheyakacheneswa terephthalic acid (PTA) mumakemikari fiber indasitiri semuenzaniso, svikiro rinoshanda rinonyanya acetic acid uye hydrobromic acid, ine corrosiveness yakasimba. Inenge mavharuvhu e8000, kusanganisira mavharuvhu epasi uye mavharuvhu ebhora, anoda kushandiswa, ane marudzi akasiyana-siyana uye nhamba huru. Naizvozvo, titanium mavharuvhu ave sarudzo yakanaka, kuwedzera kuvimbika uye kuchengeteka kwekushandisa. Kazhinji, nekuda kwekuora kweurea, mavharuvhu ekubuda nekupinza kweiyo urea synthesis tower anogona kusangana nehupenyu hwesevhisi kwegore rimwe uye akatosvika kune zvinodiwa zvekushandisa. Mabhizinesi akadai seShanxi Lvliang Fertilizer Plant, Shandong Tengzhou Fertilizer Plant, uye Henan Lingbao Fertilizer Plant vakaedza kakawanda uye pakupedzisira vakasarudza titanium valve high-pressure check valves H72WA-220ROO-50, H43WA-220ROO-50, 65, 80, uye insulation. kumisa mavharuvhu BJ45WA-25R-100, 125, nezvimwewo nokuda kwekupinzwa kunze kweurea synthesis towers, nehupenyu hwebasa hwemakore anopfuura 2, kuratidzira kumira kwakanaka kwekuora [9], kuderedza kuwanda uye mutengo wekutsiva valve.
Iko kushandiswa kwe cast titanium alloy mumusika wevharuvhu hakungogumiri kumaindasitiri ataurwa pamusoro, asi kune budiriro yakanaka mune zvimwe zvinhu. Semuyenzaniso, itsva cast titanium alloy Ti-33.5Al-1Nb-0.5Cr-0.5Si yakagadziridzwa muJapan ine zvakawanda zvakanakira senge yakaderera density, kusimba kwakakwira, uye kupfeka kwakanaka kuramba. Kana ichishandiswa muvharuvhu yekumashure yekuburitsa yeinjini dzemotokari, inogona kuvandudza kuchengetedzwa kweinjini uye kuwedzera hupenyu hwayo hwesevhisi.
- Mamwe Maindasitiri
Kuenzaniswa nekushandiswa kweakakandirwa titanium alloys muindasitiri yevharuvhu, mamwe maapplication e cast titanium alloys akawedzera. Titanium uye titanium alloys ane yakanakisa corrosion resistance, iyo yakakosha zvikuru kune maindasitiri ane corrosive zvinodiwa senge petrochemical industry. Mumaindasitiri aya, michina mikuru mikuru inoda kugadzirwa kwemaindasitiri senge volumetric pombi, zvinopisa kupisa, compressors, uye mareactors achashandisa corrosion-resistant titanium castings, iyo ine yakanyanya kudiwa pamusika. Muchikamu chemishonga, nekuda kwekuti titanium iri inozivikanwa pasi rose yakachengeteka, isiri-chepfu, uye heavy metal isina simbi, michina yakawanda yekubatsira yekurapa, maprostheses evanhu, uye zvimwe zvinogadzirwa neakakandirwa titanium alloys. Kunyanya mukurapa mazino, anenge ese mazino anokandwa akaedzwa anogadzirwa neindasitiri yakachena titanium uye Ti-6Al-4V alloy, ane yakanaka biocompatibility, mechanical properties, uye corrosion resistance. Nekune rimwe divi, nekuda kwemabhenefiti ekudzikira uye kuita kwakanaka kwetitanium uye titanium alloys, anoshandiswa zvakanyanya mumidziyo yakawanda yemitambo yakadai semakirabhu egorofu, misoro yebhora, mareketi etennis, badminton rackets, uye kubata hove. Zvigadzirwa zvakagadzirwa nazvo zvakareruka, zvine vimbiso yemhando, uye zvinofarirwa zvikuru pakati peveruzhinji. Semuyenzaniso, SP-700 itsva titanium alloy yakagadziridzwa neJapan Steel Pipe Company (N104) inoshandiswa sechinhu chepamusoro cheTaylor brand 300 series golf ball heads, iri kutengeswa zvakanyanya pamusika wepasi rose wegorofu. Kubva pakupera kwezana ramakore rechi 20, masimbi etitanium alloys akagadzira zvishoma nezvishoma indasitiri uye chiyero muminda yakaita se petrochemical, aerospace, biomedical, indasitiri yemotokari, uye mitambo nenhandaro, kubva pakuongorora kwekutanga kusvika ikozvino kwakasimba kusimudzira nekusimudzira.
