chidziwitso

Titanium Grade 4 Round Bar, yomwe imadziwikanso kuti commercially pure (CP) titanium grade 4, ndi aloyi yamphamvu kwambiri ya titaniyamu yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kukana kwa dzimbiri, biocompatibility, ndi makina. Kupanga kwa Titanium Grade 4 Round Bar kumaphatikizapo njira yovuta yomwe imaphatikiza njira zamakono zazitsulo ndi njira zopangira zolondola. Cholemba ichi chabulogu chidzasanthula zovuta zopangira zinthu zosiyanasiyanazi, ndikuwunika njira zazikulu ndi malingaliro omwe akukhudzidwa popanga.

Ndi masitepe otani ofunikira popanga Titanium Grade 4 Round Bar?

Kupanga kwa Titanium Grade 4 Round Bar kumayamba ndikuchotsa titaniyamu kuchokera ku miyala yake, yomwe nthawi zambiri imakhala ilmenite kapena rutile. Njirayi, yomwe imadziwika kuti Kroll, imaphatikizapo magawo angapo kuti mupeze siponji yoyera ya titaniyamu. Siponji ya titaniyamu imasungunuka ndi kusakaniza ndi chitsulo, carbon, nitrogen, ndi mpweya wochepa kuti akwaniritse zomwe zili mu Giredi 4 titaniyamu.

Kapangidwe ka alloy kakakwaniritsidwa, zinthuzo zimadutsa njira zingapo zopangira kupanga mawonekedwe ozungulira. Izi zimayamba ndi kuponyedwa kwa ingot, pomwe aloyi wosungunuka wa titaniyamu amatsanuliridwa mu nkhungu ndikuloledwa kulimba. Ingots zomwe zimatsatiridwazi zimayamba kugwira ntchito zoyambira kupanga monga kufota kapena kugubuduza kuti aphwanye kapangidwe kake ndikuwongolera makina azinthuzo.

Gawo lotsatira lofunika kwambiri popanga ndikugwira ntchito yotentha. Aloyi ya titaniyamu imatenthedwa ndi kutentha pamwamba pa malo ake a recrystallization (nthawi zambiri kuzungulira 800-950 ° C kwa titaniyamu ya Grade 4) ndiyeno amapangidwa pogwiritsa ntchito njira zosiyanasiyana monga extrusion, rolling, kapena forging. Njira yogwirira ntchito yotenthayi imathandizira kukonzanso kapangidwe ka tirigu, kupangitsa kuti ikhale yofanana, ndikuwonjezera mphamvu zonse zazinthuzo komanso ductility.

Pambuyo pogwira ntchito yotentha, bar yozungulira ya titaniyamu imatha kugwira ntchito mozizira kuti ionjezerenso kukula kwake ndi kumaliza kwake. Izi zingaphatikizepo kujambula kozizira kapena kutembenuza ntchito, zomwe zimathandiza kukwaniritsa kulolerana kwambiri komanso kukonza makina azinthu pogwiritsa ntchito kuumitsa ntchito.

Pa nthawi yonse yopangira zinthu, njira zoyendetsera bwino zimayendetsedwa kuti zitsimikizire Titanium Grade 4 Round Bar imakwaniritsa zofunikira. Izi zikuphatikiza kuyesa pafupipafupi kwa kapangidwe ka mankhwala, kusanthula kwa microstructure, komanso kuwunika kwazinthu zamakina kuti zitsimikizire kuti zinthuzo zikugwirizana ndi miyezo yamakampani monga ASTM B348 kapena AMS 4928.

Kodi chithandizo cha kutentha chimakhudza bwanji katundu wa Titanium Grade 4 Round Bar?

Chithandizo cha kutentha chimagwira ntchito yofunika kwambiri pakukhathamiritsa kwa Titanium Grade 4 Round Bar. Ngakhale kuti titaniyamu ya Grade 4 sichitha kutentha mofanana ndi ma aloyi ena a titaniyamu, njira zina zochizira kutentha zimatha kugwiritsidwa ntchito kuti zikwaniritse zomwe mukufuna ndikuchepetsa kupsinjika kwamkati komwe kumachitika popanga.

Njira imodzi yochizira kutentha kwa Titanium Grade 4 Round Bar ndikuchepetsa kupsinjika. Izi zimaphatikizapo kutenthetsa zinthu ku kutentha kwapakati pa 480-650 ° C kwa nthawi yodziwika, kenako ndikuzizira pang'onopang'ono. Kuchepetsa kupsinjika kumathandizira kuchepetsa kupsinjika kotsalira komwe kumatha kuchitika popanga kapena kupanga makina, kuwongolera kukhazikika kwa mawonekedwe ndikuchepetsa chiwopsezo cha nkhondo kapena kupotoza pakukonza kapena ntchito.

Annealing ndi njira ina yochizira kutentha yomwe ingagwiritsidwe ntchito ku Titanium Grade 4 Round Bar. Kuyang'ana kwathunthu kumaphatikizapo kutenthetsa zinthuzo ku kutentha kozungulira 700-785 ° C, kugwira kwakanthawi, kenako kuzirala pang'onopang'ono. Izi zimathandizira kufewetsa zakuthupi, kukulitsa ductility, ndikuwongolera machinability. Kuyang'ana kumatha kukhala kopindulitsa makamaka pamene bala yozungulira ikufunika kuchitidwa machining kapena kupanga maopaleshoni ambiri.

Nkofunika kuzindikira kuti kutentha mankhwala a Titanium Grade 4 Round Bar ziyenera kuyendetsedwa mosamala kuti zisakule kwambiri kapena kuipitsidwa. Kugwirizana kwakukulu kwa titaniyamu kwa okosijeni ndi nayitrogeni pa kutentha kokwera kumafuna kugwiritsa ntchito mlengalenga woteteza kapena njira zochizira kutentha kwa vacuum kuti tipewe kuphulika kwa pamwamba.

Njira yochizira kutentha imathanso kukhudza microstructure ya Titanium Grade 4 Round Bar, zomwe zimakhudza makina ake komanso kukana kwa dzimbiri. Poyang'anira mosamala kutentha ndi kuziziritsa, opanga amatha kukweza bwino pakati pa mphamvu ndi ductility kuti akwaniritse zofunikira za ntchito.

Ndizovuta zotani pakuwongolera kwabwino kwa Titanium Grade 4 Round Bar kupanga?

Kuwonetsetsa kuti pakupanga kwa Titanium Grade 4 Round Bar kumabweretsa zovuta zingapo zomwe opanga amayenera kuthana nazo pogwiritsa ntchito njira zowongolera bwino. Chimodzi mwazinthu zodetsa nkhawa kwambiri ndikusunga mawonekedwe ake enieni a titaniyamu a Giredi 4. Izi zimafuna kuwongolera mosamalitsa ma alloying ndi zonyansa panthawi yonse yosungunuka ndi kuponya.

Kuyesa kosawononga (NDT) kumatenga gawo lofunikira pakuwongolera kwapamwamba kwa Titanium Grade 4 Round Bar. Njira monga kuyesa kwa ultrasonic, kuyang'ana kwa eddy panopa, ndi kufufuza kwa radiographic kumagwiritsidwa ntchito kuti azindikire zolakwika zamkati, inclusions, kapena inhomogeneities zomwe zingasokoneze ntchito ya zinthuzo. Njira za NDT izi zimalola opanga kuzindikira ndi kuthana ndi zovuta zomwe zingachitike popanda kusiya kukhulupirika kwa chinthucho.

Ubwino wa pamwamba ndi mbali ina yofunika kwambiri Titanium Grade 4 Round Bar kupanga komwe kumafuna kuyang'anitsitsa mosamala. Kuchulukanso kwa titaniyamu pakutentha kokwera kumatha kubweretsa kuipitsidwa pamwamba kapena kupanga gawo la alpha, zomwe zitha kusokoneza zinthu zakuthupi. Opanga amayenera kukhazikitsa njira zowongolera panthawi yotentha ndi kutentha kuti achepetse zovutazi ndipo atha kugwiritsa ntchito njira monga kukhetsa asidi kapena kuchotsa ndi makina kuti athetse kusanjikiza kulikonse komwe kwawonongeka.

Kulondola kwapang'onopang'ono komanso kusasinthasintha ndizovuta zazikulu pakupanga Titanium Grade 4 Round Bar. Kuchuluka kwa mphamvu ndi kulemera kwa zinthuzo komanso mawonekedwe apadera amakina angapangitse kuti zikhale zovuta kukwaniritsa kulolerana kolimba poyerekeza ndi zitsulo zina. Njira zamakono zamakina, kuwongolera njira zolondola, ndikuwunika pafupipafupi ndikofunikira kuti zitsimikizire kuti zozungulira zozungulira zikukwaniritsa zofunikira.

Kuwongolera kwa Microstructure ndi gawo lina lofunikira pakutsimikizira kwamtundu wa Titanium Grade 4 Round Bar kupanga. Kukula kwa njere, mawonekedwe ake, ndi kagawidwe kake kumatha kukhudza kwambiri makina ndi magwiridwe ake. Opanga amayenera kuyang'anira mosamala magawo opangira ma thermomechanical kuti akwaniritse mawonekedwe ang'onoang'ono omwe akufuna ndipo atha kugwiritsa ntchito njira monga ma microscope kapena ma electron backscatter diffraction (EBSD) kuti atsimikizire mawonekedwe a zinthuzo.

Pomaliza, kutsatiridwa ndi zolemba zambiri kumabweretsa zovuta zomwe zikuchitika pakupanga Titanium Grade 4 Round Bar. Poganizira momwe zinthuzo zimagwirira ntchito m'mafakitale monga zakuthambo ndi zida zamankhwala, kusunga zolemba zonse zazinthu zopangira, magawo opangira, ndi zotsatira zoyesa ndikofunikira. Kukhazikitsa njira zotsogola zolimba komanso kutsatira miyezo yamakampani pazolembedwa kumathandiza kuwonetsetsa kuti gulu lililonse la Titanium Grade 4 Round Bar litha kutsatiridwa kuyambira pomwe linayambira komanso kuti zofunikira zonse zakwaniritsidwa.

Pothana ndi zovutazi kudzera munjira zapamwamba zopangira, kuwongolera njira zokhazikika, ndi mapulogalamu otsimikizira zaubwino, opanga Titanium Grade 4 Round Bar amatha kuperekera zida zapamwamba zomwe zimakwaniritsa miyezo yoyenera yamakasitomala awo m'mafakitale osiyanasiyana.

Ku SHAANXI CXMET TECHNOLOGY CO., LTD, timanyadira zamitundu yathu yayikulu, yomwe imathandizira zosowa zosiyanasiyana zamakasitomala. Kampani yathu ili ndi luso lapadera lopanga ndi kukonza, kuwonetsetsa kuti zinthu zathu ndi zapamwamba komanso zolondola.
