Akatswiri akamatchula zigawo za Stellite za mavavu a hydraulic, mapampu, kapena ma nozzles ovala kwambiri, sikuti amangogula zitsulo-amagula kukhazikika kwapakati pa 300 MPa, kukana kugunda pa 650 ° C, ndi kusasinthika kwapang'onopang'ono pamagulu 500. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni Fakitale ya satellite nkhani - osati malo oyambira omwe ali ndi chingwe chimodzi cha cobalt-alloy, koma malo opangira AMS 5387, T800, ndi ma superalloys ena a cobalt-nickel kuchokera ku billet yaiwisi mpaka yomaliza.
Tawona mapulojekiti ambiri akuchedwa chifukwa cha njira zochiritsira zosagwirizana ndi kutentha - pomwe wogulitsa amawonjezera Stetellite 6 asanapange makina, ndiyeno nkudumpha njira yothetsera pambuyo popera komaliza. Chotsatira? Kutsika kwa 12% mu kuuma kwa Rockwell C ndi kuphulika msanga m'mikono yapampu yobwerezabwereza. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Chigawo chilichonse cha Stellite chimayamba ndi ma ingots ovomerezeka a AMS 5387 kapena T800, otsimikiziridwa ndi kusanthula kwa spectrographic musanaponye kapena kupanga. Palibe kuchotserapo. Palibe "batch waivers". Timatsata nambala iliyonse yosungunuka, kuthamanga kwa ng'anjo, ndi kuzizira - osati chifukwa ndi mapepala, koma chifukwa kusiyana kwa 0.3% mu carbon content kumasintha moyo wa 40% muzopaka zonyansa.
Kuphatikizika koyima sikutsatsa malonda apa-ndi momwe timalamulira zomwe ena sangathe. Otsatsa ambiri a Stellite amatulutsa makina kapena chithandizo cha kutentha. Timachita zonse m'nyumba, pamtunda womwewo wa ISO-certified. Maselo athu a 5-axis CNC adadula Stellite 6 yolimba molunjika pambuyo pa HIP (kukankhira kotentha kwa isostatic), kuchotsa kupotoza kwa pambuyo pa kutentha komwe kumawononga ma callout a GD&T ngati kulolerana kwamalo ± 0.015 mm pamiyala ya nozzle. Pakadali pano, njira yathu yopangira ndalama imayendetsa zipolopolo za ceramic zomwe zimatenthedwa mpaka 1,100 ° C-zofunikira kuti tipewe kuchepa kwapang'onopang'ono mu mapulagi amtundu wa cobalt alloy omwe amagwiritsidwa ntchito m'matumba a BOP akunyanja. Makasitomala m'modzi adasintha kuchokera kwa wogulitsa waku Europe pambuyo poti mpando wawo wa valve wa Stellite 21 utasweka panthawi yanjinga yotentha; athu adadutsa 12,000 mkombero pa -40 ° C mpaka +200 ° C popanda microfracture. Kusiyana kwake? Timaponya, makina, kuchepetsa kupsinjika, ndikumaliza zonse motsatana-palibe zophatikizira zapakati pazigawo, palibe mipata ya mbiri yamatenthedwe.
Kuchita zenizeni padziko lapansi kumatengera zinthu zitatu zomwe sizingakambirane: kutsatiridwa kwa zinthu, kukhulupirika kwa geometric, ndi kutsimikizika kwa magwiridwe antchito. Timalemba scan iliyonse ya CMM-X, Y, Z, ndi data ya vector yapamtunda-panyumba iliyonse yokakamiza. Ngati kasitomala atchula Ra 0.4 µm pankhope yosindikizidwa, timayesa ndi stylus profilometer * ndi* kutsimikizira kumamatira kwamatepi kudzera mu mayeso a tepi ya ASTM B571 - osati "kungoyang'ana chithunzi chilichonse." Pazigawo zapampu za AMS 5387, timayesa kuyesa kwa ultrasonic (UT) kupita ku ASTM E114 pa 100% ya maere, kugwira porosity yapansi panthaka yomwe X-ray imaphonya mumitundu yovuta ngati ma piston pump silinda nyumba. Ndipo pamene makina oyeretsera ku Southeast Asia adapempha ma nozzles a aloyi a cobalt omwe adavotera ntchito ya H₂S, sitinangokumana ndi NACE MR0175-tinawonjezera kutsimikizira kwachiwiri ndi kutsimikizira kusindikiza kwa sulfure. Chifukwa "kumvera" sikokwanira pamene hydrogen embrittlement imayambitsa kutsekedwa.
Kusankha fakitale ya Stellite kumatanthauza kusankha yemwe ali ndi chiopsezo. Mavenda ena amatchula nthawi zotsogola mwachangu podumpha njira yothetsera vutoli. Ena amagwiritsa ntchito zida zachizindikiro zomwe zimachititsa kuti anthu azilankhulana pa malo a Stellite 12—kuwononga chisindikizo. QINGDAO QIANGSENYUAN sichimakulitsa liwiro lokha. Timakonzekeretsa kuphatikizira koyamba: kuunikanso kwa GD&T tisanatchule, kuyankha pakupanga pasanathe maola 48, ndikutsimikizira kwachiwonetsero ndikuyesa kuzungulira kwa katundu ngati kuli kofunikira. Makasitomala athu ku North America gawo la ntchito zamafuta ku North America amadalira ife pa ma winch center shaft rollers omwe amatha maola 18,000 m'malo am'madzi odzaza mchere - palibe kukonzanso, kulephera kwamunda. Kudalirika kumeneku kumabwera chifukwa chopanga ma aloyi opangidwa ndi cobalt - osati nthawi zina, koma tsiku lililonse. Kuchokera pakuthandizira mapangidwe mpaka kutsata mawonekedwe, kuchokera ku mapulagi a T800 aloyi kupita ku ma nozzles a Stellite 6, timapanga zomwe zimagwira ntchito pomwe kulephera sikungatheke. Chofunikira chanu chotsatira cha Stellite chikafika pa desiki, funsani: kodi fakitale yanu imadziwa kusiyana pakati pa kuuma ndi kulimba? Kapena amangogaya zomwe umatumiza?
