Xa iinjineli zichaza amacandelo e-Stellite kwiivalvu ze-hydraulic, izindlu zempompo, okanye i-nozzles ephezulu, abathengi nje isinyithi-bathenga ukuzinza kwe-dimensional phantsi kwe-300 MPa yoxinzelelo, ukuxhathisa kwi-galling kwi-650 ° C, kunye ne-microstructural consistency kuwo wonke ama-batches angama-500. Yiyo loo nto ukukhangela kwinyani Umzi-mveliso weStellite imiba-hayi isiseko esiqhelekileyo esinomgca omnye we-cobalt-alloy, kodwa indawo eyenzelwe i-AMS 5387, T800, kunye nezinye ii-cobalt-nickel superalloys ukusuka kwi-billet eluhlaza ukuya kwindawo egqityiweyo.
Siye sabona iiprojekthi ezininzi zilibazisekile ngemijikelo yonyango lobushushu obungahambelaniyo-apho umthengisi ethatha iStellite 6 phambi komatshini, aze atsibe isisombululo emva kokusila okokugqibela. Isiphumo? Ukuhla nge-12% kubulukhuni be-Rockwell C kunye nokuchitheka kwangaphambi kwexesha kwimikhono yempompo ebuyelanayo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke icandelo le-Stellite liqala ngeengots eziqinisekisiweyo ze-AMS 5387 okanye ze-T800, ziqinisekiswe ngohlalutyo lwe-spectrographic ngaphambi kokuphosa okanye ukukhwabanisa. Akukho ngaphandle. Akukho "batch waivers." Silandelela inombolo nganye yokunyibilika, i-furnace run, kunye nesantya sokupholisa-kungekhona ngenxa yokuba ngamaphepha, kodwa ngenxa yokuba i-0.3% yenguqu kumxholo wekhabhoni iguqula ubomi bokugqoka nge-40% kwizicelo ze-abrasive slurry.
Ukudityaniswa okuthe nkqo akuyiyo ijargon yokuthengisa apha-yindlela esilawula ngayo into abanye bangakwaziyo ukuyenza. Uninzi lwababoneleli beStellite bakhupha oomatshini okanye unyango lobushushu. Senza zombini endlwini, kumgangatho ofanayo we-ISO-certified. Iiseli zethu ze-5-axis ze-CNC zinqumle i-Stellite 6 eqinile ngokuthe ngqo emva kwe-HIP (i-isostatic eshushu icinezela), isusa ukugqwethwa kwe-post-heat-treat eyonakalisa i-GD & T callouts njengokunyamezela isikhundla ± 0.015 mm kwi-nozzle orifices. Okwangoku, umgca wethu wokuphosa utyalo-mali uqhuba iimbumba ze-ceramic ze-ceramic preheated ukuya kwi-1,100 ° C-ibalulekile ekuthinteleni i-micro-shrinkage kwiiplagi ze-cobalt alloy alloy ezisetyenziswa kwi-stacks ye-BOP engaselunxwemeni. Omnye umthengi utshintshile kumthengisi waseYurophu emva kokuba isitulo sabo sevalve yeStellite 21 siqhekeke ngexesha lokuhamba ngebhayisekile eshushu; yethu yadlula imijikelo ye-12,000 kwi -40 ° C ukuya + 200 ° C ngaphandle kwe-microfracture. Umehluko? Siphosa, umatshini, sinciphisa uxinzelelo, kwaye sigqibe konke ngokulandelelana-akukho zixhobo zokusebenzela, akukho zithuba zembali yobushushu.
Ukusebenza kwehlabathi lokwenyani kuxhomekeke kwizinto ezintathu ezingenakuxoxisana: ukulandelelwa kwezinto, ukuthembeka kwejometri, kunye nokuqinisekiswa okusebenzayo. Siloga yonke i-CMM scan-X, Y, Z, kunye nedatha yevektha yomphezulu-kwindlu nganye yevalve yoxinzelelo. Ukuba umthengi uxela i-Ra 0.4 µm kubuso obutywiniweyo, siyayilinganisa ngestylus profilometer *kwaye* singqinisise ukuncamatheliswa kokunamathela ngovavanyo lweteyiphu ye-ASTM B571—hayi nje “ukuhlola umzobo ngamnye.” Kwiindawo zempompo ze-AMS 5387, siqhuba uvavanyo lwe-ultrasonic (UT) ukuya kwi-ASTM E114 kwi-100% yamaqashiso, sibambe i-porosity engaphantsi komhlaba ephoswa yi-X-ray kwiijometri ezintsonkothileyo njengezindlu zepiston pump cylinder. Kwaye xa i-Southeast Asia yokucokisa icela imilomo ye-cobalt alloy elinganiswe ngenkonzo ye-H₂S, asizange sidibane ne-NACE MR0175-songeze i-passivation yesibini kunye nokuqinisekiswa koshicilelo lwesulfure. Ngenxa yokuba "ukuthobela" akwanelanga xa i-hydrogen embrittlement ibeka ingozi yokuvalwa.
Ukukhetha umzi-mveliso weStellite kuthetha ukukhetha ukuba ngubani umngcipheko. Abanye abathengisi bacaphula amaxesha okukhokela ngokukhawuleza ngokutsiba isisombululo se-annealing. Abanye basebenzisa iindlela zezixhobo eziqhelekileyo ezibangela ukuba kubekho amanqaku encoko kwiStellite 12 umphezulu—ukonakalisa ingqibelelo yetywina. I-QINGDAO QIANGSENYUAN ayilungiseleli isantya sodwa. Silungiselela umiliselo lwexesha lokuqala: Uphononongo lwe-GD&T phambi kokucaphula, ingxelo yokwenziwa kwezinto ngaphakathi kweeyure ezingama-48, kunye nokuqinisekiswa kweprototype ngovavanyo lomjikelo womthwalo ukuba kuyafuneka. Abathengi bethu kwicandelo leenkonzo ze-oyile yaseMntla Melika baxhomekeke kuthi kwii-winch center shaft rollers eziqhuba iiyure ze-18,000 kwiindawo zaselwandle ezinetyuwa-akukho kuphinda kusebenze, akukho kusilela kwintsimi. Oko kuthembeka kuvela ekwenzeni i-cobalt-based alloys-kungekhona ngamaxesha, kodwa imihla ngemihla. Ukusuka kwinkxaso yoyilo ukuya kwi-traceability ye-dimensional, ukusuka kwi-T800 i-alloy plugs ukuya kwii-nozzle ze-Stellite 6 zesiko, sakha oko kusebenza apho ukusilela kungenakuzikhethela. Xa imfuno yakho elandelayo yeStellite ifika kwidesika, buza: ngaba umzi-mveliso wakho uyawazi umahluko phakathi kobunzima kunye nokuqina? Okanye bayayigaya nje lento uyithumelayo?
