Iyo abajenjeri bagaragaje ibice bya cobalt alloy casting, ntibategeka ibyuma gusa - baba bafite umutekano muke, bakarwanya kwambara, hamwe numutekano muke munsi yumuvuduko ukabije, ubushyuhe, cyangwa ruswa. Intebe imwe idahwitse ya valve cyangwa amazu ya pompe yubatswe yakozwe muri AMS 5387 cobalt alloy irashobora gutera kunanirwa kwa casade muri sisitemu ya hydraulic cyangwa ibikoresho bya peteroli. Niyo mpamvu biva muri a cobalt alloy casting ibice uruganda hamwe na disipuline yemejwe ya metallurgjiya - ntabwo ari ubushobozi bwo guta gusa - ntabwo iganirwaho.
Kwisi-kwisi ya cobalt isaba ibirenze ubushyuhe n'umucanga
Twabonye imishinga myinshi ihagaze kuko abatanga isoko bafataga amavuta ya cobalt nkicyuma gisanzwe. Cobalt ishingiye kuri superalloys - cyane cyane amanota ya T800 na AMS 5387 - igabanuka bitateganijwe mugihe cyo gukomera, irwanya imashini nyuma yo kuyitera, kandi igateza imbere microsegregation niba igipimo cyo gukonjesha kitagenzuwe neza. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cobalt casting itangirana nibikoresho byemewe byemewe: buri gice cyubushyuhe gitwara raporo yuzuye yerekana amashusho, kugenzura ingano, hamwe namateka yubushyuhe. Nta cyiciro cyinjira mu itanura kidahuye n’ibigize imiti na ASTM F75 cyangwa AMS 5710 - kugeza kuri ± 0.02% kuri chromium na ± 0.01% kuri karubone.
Uruganda rwacu rukoresha ishoramari rya nozzles hamwe namacomeka bisaba radiyo ifatanye kandi ikarangira hejuru ya Ra 1.6 µm - hamwe nicyatsi kibisi-cyumucanga kubice binini, byuzuye byubatswe nkamazu ya pompe ya pompe. Icy'ingenzi, duhuza ibisubizo nyuma yo guterwa annealing * murugo *, twirinda gutinda kwabandi bantu gutinda bishobora guterwa no guhunika ingano cyangwa sigma icyiciro. Umukiriya umwe wo muri Amerika ya ruguru yagabanije kunanirwa mu murima ku kigero cya 73% nyuma yo kuva mu isoko ryohereza ibicuruzwa mu bice bya pompe AMS 5387 - kubera ko twagize umwanya hagati ya 25-35 µm, ntabwo 50+ µm dusanzwe dukora muri rusange.
Guhuza Vertical ntabwo ari ijambo ryijambo-ni ubwishingizi buke
Inganda zimwe zitera ibice bya cobalt. Abandi barabikora. Bake bakora byombi - mugihe ugenzura ubushyuhe, GD&T kwemeza, hamwe nubusugire bwubuso hejuru yumurimo umwe. Icyo cyuho niho habaho kwihanganira stack-up. Twapimye gutandukana kugera kuri mm 0,12 mm kuri bores zikomeye mugihe cyo gutera no gutunganya bibera ahantu hatandukanye - kabone niyo byashushanyije "0,05".
Mu kigo cacu cyemewe na ISO 9001 i Qingdao, cobalt alloy nozzle iva mubishashara igana ubugenzuzi bwa nyuma bwa CMM itiriwe iva ku musaruro. Ibigo byacu 5-axis CNC ifite imyanya isubirwamo ya ± 0.003 mm kuri T800 ikomeye; abagereranya optique bagenzura kwihanganira umwirondoro ku bice bito bikikijwe kugeza kuri mm 0.3 z'ubugari. Kubikoresho bya winch center shaft bikoreshwa mumodoka yubuhanga, duhuza casting ya centrifugal (kubwubucucike bumwe) hamwe no guhinduka cyane aho gusya - gukuraho ibyangiritse munsi yubutaka mugihe tugera kuri HRC 42-46 gukomera hamwe na 0.005 mm.
Ibi ntabwo ari theoretical. Iyo pompe yo mu majyepfo yuburasirazuba bwa Aziya OEM yari ikeneye amacomeka ya cobalt adasanzwe hamwe na geometrike idahwitse hamwe numuyoboro wa coolant, twatanze prototypes ikora muminsi 11 yakazi - atari ibyumweru - twifashishije ibikoresho byaturutse kumirimo yabanjirije AMS 5387 no kwemeza inzira zitemba zifite imbaraga zo kubara mbere yo gusuka.
Igenzura ryiza risubiza ibibazo nyabyo - ntabwo ari urutonde rwibintu gusa
"Kugenzura byatsinzwe" ntacyo bivuze keretse niba uzi * icyo * cyagenzuwe, * uko *, na * kurwanya icyo *. Ntabwo twishingikiriza kuri cheque yanyuma. Ingobyi yinjira ya cobalt ikorerwa spark emission spectroscopy hamwe na ultrasonic yipimisha kubusa imbere. Mugihe cyo gukina, thermocouples ikurikirana ibice bikomeye mugihe nyacyo. Nyuma yo gutunganya, umubiri wose wumuvuduko wibizamini bya hydrostatike kuri 1.5 × umuvuduko wakazi - wongeyeho igenzura ryirangi ryamabara kuri zone zose zasanwe.
Icy'ingenzi cyane, turagumana ibisobanuro byuzuye: nimero myinshi, gushonga ibiti, ubushyuhe bwo kuvura umurongo, indangamuntu ya raporo ya CMM, hamwe n umukono wumukoresha byinjijwe muri buri gice cya digitale. Abakiriya babigeraho babinyujije kumurongo wizewe - ntabwo ari PDF, ariko nkibishobora gushakishwa, amakuru yatanzweho igihe. Imikorere imwe ya hydraulic ya sisitemu yo mu Burayi yagabanije igihe cyayo cyo kugenzura ku kigero cya 65% nyuma yo gukoresha sisitemu yo gukurikirana ibice bya cobalt.
Dushiraho kandi ibendera rishobora kubaho hakiri kare - ntabwo ari umurongo, ariko nkibindi bikorwa. Niba igishushanyo gisaba radiyo 0,2 mm kuri T800 icomeka ku rutugu, tuzasaba radiyo 0,3 mm hamwe na kashe ihwanye na 40% ubuzima bwibikoresho. Nta jargon. Nta gutinda. Gusa ubucuruzi bushyigikiwe na fiziki.
Ni ukubera iki gutondeka neza cobalt bigifite akamaro-muri 2024 na nyuma yaho
Amavuta ya Cobalt ntabwo ari ibikoresho byumurage. Barashoboza-gen-progaramu ikurikira: umuvuduko ukabije wa hydrogène yongerera pompe, sisitemu yo gukora amashanyarazi yo mu nyanja, hamwe na moteri ya hydraulic moteri yimodoka zigenga. Ibi birasaba guhanagura, kurwanya umunaniro mwinshi, no kutihanganira zeru kuri microcrack - ibihe aho cobalt irusha nikel cyangwa ibyuma bitagira umwanda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yibanda gusa kubikorwa byo murwego-rwimikorere ikora-ntabwo ari imitako ishushanya cyangwa imirongo mike. Ibyo byibandaho bikarishye ubumenyi bwibikorwa byacu: uburyo kwaguka kwubushyuhe bwa cobalt gukorana nintebe zicyuma, uburyo guhangayika gusigara bigira ingaruka kumuzingo nyuma yo gusiganwa ku bushyuhe, uko kurangiza hejuru bigira ingaruka kumasuri ya cavitation mumfatiro za pompe. Ntabwo tugurisha ibice bya cobalt. Dutanga ibahasha yimikorere igenzurwa-hamwe namakuru inyuma yibisobanuro byose.
Niba gusaba kwawe kurimo umuvuduko uri hejuru ya 350, ubushyuhe burenga 400 ° C, cyangwa itangazamakuru ryangiza nkamavuta yuzuye umucanga, tangira usubiremo ibintu - ntabwo ari ugusaba amagambo. Baza ibijyanye no kwerekana raporo yerekana, ibisubizo hagati yikizamini cya ruswa kuri ASTM G28, kandi niba cobalt alloy casting ibice uruganda ifite ubushyuhe bwo kuvura cycle yemewe. Umufatanyabikorwa mwiza ntabwo azahura gusa nimyandikire yawe. Bazagufasha gutunga intera iri hagati yo gutsindwa n'imikorere.
