Xa impompo yehydraulic ingasebenzi kwindawo yokulawula i-oyile ekude nonxweme-okanye i-winch shaft ibambe ngaphakathi kwi-excavator yemigodi-oyena nobangela awufane uyilwe. Iyanxiba. Kwaye kungekhona nje nayiphi na into yokunxiba: i-micro-abrasion, i-galling, i-thermal fatigue phantsi kwe-300 ° C imithwalo ye-cyclic. Kulapho I-Stellite 6 inxalenye yefektri ukukwazi kuyeka ukuba ngokuzikhethela. Iba ngumahluko phakathi kweeyure ezingama-8,000 zenkonzo kunye nokusilela kwintsimi eyintlekele.
Siphose imilomo ye-Stellite 6 yeenkqubo zokutofa kweasidi yoxinzelelo oluphezulu eSaudi Arabia-kwaye sizibukele ziphuma kwizizukulwana ezithathu zokutshintsha okusemgangathweni. Senze oomatshini bezindlu ze-AMS 5387 piston pump cylinder yee-OEMs zaseJamani ezifuna ±0.015 mm ukungqukuva kwi-200 mm ubukhulu, kunye nokugqitywa komphezulu u-Ra ≤0.4 µm emva kokusila kokugqibela. Ezi ayizizo iinkcazo zethiyori. Ziibenchmarks zemihla ngemihla kwiziko lethu le-ISO-certified foundry kunye neziko lomatshini eQingdao.
I-Stellite 6 ayisiyo "enye i-cobalt alloy." Ukubunjwa kwayo-ngokumalunga ne-65% ye-Co, i-28% Cr, i-4% W, kunye ne-Ni, i-Fe, kunye ne-C-yenza i-matrix ye-chromium carbides enzima efakwe kwisisombululo esiqinileyo se-cobalt. Oko kuyinika ukuxhathisa okungenakuthelekiswa nanto kwintsimbi ukuya kwintsimbi, ukubola kwiindawo ezityebileyo ngekloridi, kunye nokuthamba kwe-thermal ukuya kuthi ga kwi-500°C. Kodwa nantsi into abathengi abaninzi abangayijongiyo: ukuphosa i-Stellite 6 akufani nokuphosa intsimbi. Indawo yayo yokunyibilika ephezulu (1,290-1,350 ° C), ukumanzi okuphantsi, kunye nokuncipha okugqithisileyo kufuna i-gating ekhethekileyo, ulawulo oluchanekileyo lokungunda, kunye nonyango lobushushu be-homogenization emva kokuphoswa. Tsiba naliphi na inyathelo-kwaye ufumana i-porosity, i-carbide segregation, okanye i-brittle interdendritic phases. Siye sabona abathengi besala i-40% ye-batch-batch castings evela kubaboneleli abangafanelekanga. Isivuno sethu kwi-complex Stellite 6 investment castings iqhuba kwi-92% + kuba silawula zonke izinto eziguquguqukayo: ukuqinisekiswa kwezinto ekrwada (zonke i-T800-grade cobalt base alloys ezilandelekayo kwiingxelo zovavanyo lokusila), i-vacuum-melted ingot sourcing, kunye nexesha lokwenyani lokulinganisa i-thermal ngexesha lokuqina.
Ukudityaniswa ngokuthe nkqo kwahlula iifektri ezithembekileyo zeStellite 6 kubathengisi bempahla. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Casting, CNC machining, kunye nokugqiba kwenzeka phantsi kophahla olunye-kunye ne-metrology ekwabelwana ngayo, ukutolika kwe-GD&T okudibeneyo, kunye nokulibaziseka kwe-handoff. Xa umthengi ethumela umzobo weplagi ye-cobalt alloy non-standard kunye neziteshi zokupholisa ezi-asymmetric kunye ne-0.008 mm ukunyamezela kwesigxina kwiimpawu ezintlanu ezinentambo, asikhupheli ngaphandle kokujika. Siyiqhuba kwi-5-axis yethu ye-DMG MORI NTX 1000, sisebenzisa izixhobo ezinencam ye-PCD ezilungiselelwe i-cobalt alloys, kunye ne-laser esebenzayo yokuhlola ukungqinisisa ubukhulu bodonga ngaphambi kokusila kwe-ID yokugqibela. Akukho mthengisi wangaphandle oqondayo ukuba uxinzelelo olushiyekileyo lokuphosa luchaphazela njani ukugqwethwa komatshini kumzimba wevalve ende oyi-320 mm. Senza-kuba siyayiphosa, siyiphatha ngokushushu, siyimatshini, kwaye siyihlole ngenkqubo efanayo yeCMM ukusuka ekuqaleni ukuya ekupheleni.
Ukusebenza kwehlabathi lokwenyani kuxhomekeke kwizinto ezintathu ezingaxoxisiyo-hayi amabango okuthengisa. Okokuqala: ukuhambelana kwezinto. Iqashiso ngalinye le-Stellite 6 lenziwa uhlalutyo lwe-spectrographic, ukuqina kwemephu kuwo wonke amacandelo anqamlezayo, kunye ne-ASTM E112 yokuqinisekisa ubungakanani beenkozo. Okwesibini: ukunyaniseka komda. Siqinisekisa iindawo ezibalulekileyo ngokusebenzisa i-profilometers ebonakalayo-kungekhona nje i-CMM-ukubamba i-micro-topography echaphazela ukunyaniseka kwetywina. Okwesithathu: ukuqinisekiswa okusebenzayo. Ngaphambi kokuthunyelwa, yonke ivalve yoxinzelelo ifumana uvavanyo lwe-hydrostatic kwi-1.5 × ilinganiswe uxinzelelo lokusebenza; indlu nganye yempompo ijongwa ukuvuza ngehelium mass spectrometry. Abathengi kuMntla Merika naseYurophu ababuzi izatifikethi-bacela iingxelo zovavanyo oluthe ngqo kwibhetshi ezinesitampu sexesha, ii-ID zabaqhubi, kunye nesitampu sokulinganisa izixhobo. Siyabahambisa.
Ukuba isicelo sakho sibandakanya i-slurries e-abrasive, i-steam yobushushu obuphezulu, okanye ukulayisha ngebhayisikile ngaphezulu kwe-200 MPa, i-Stellite 6 ayisebenzi kakhulu. Yi-inshurensi. Kodwa i-inshurensi isebenza kuphela xa umboneleli enamava aqinisekisiweyo-kungekhona nje iincwadana. Khangela impumelelo ebhaliweyo kwicandelo lakho: iindibano zempompo zezicelo ze-subsea, i-winch center shaft rollers ye-heavy-duty cranes, okanye imilomo ye-cobalt alloy yezityalo zokukhupha ityuwa. Jonga ukuba banazo na iimvume zenkqubo ye-AMS 5387—hayi nje izatifikethi zezinto eziphathekayo. Qinisekisa ukuba iirekhodi zabo zomgangatho zibandakanya ukulandeleka ngokupheleleyo ukuya kwinani lobushushu le-cobalt ingot. Emva koko uthelekise uqeqesho lonikezelo: ngaba bangakwazi ukubamba iifestile zeentsuku ezi-±3 kwii-odolo zevolumu ephakathi ngaphandle kokukhawulezisa iintlawulo? Lo ngumqondiso wenyaniso I-Stellite 6 inxalenye yefektri-hayi ivenkile yomsebenzi enecwecwe le-cobalt alloy.
