Iyo abajenjeri bagaragaje ibishushanyo mbonera byerekana ibice byicyuma, ntabwo bahitamo inzira-bahitamo inzira igana kumurongo uhamye, ubudahemuka bwubuso, hamwe na microstructure isubirwamo mubice bikora munsi yumuvuduko ukabije, ubushyuhe, cyangwa kwambara. A. shell mold casting uruganda igomba gukora ibirenze gusuka icyuma gishongeshejwe mumusenyi uhujwe. Igomba guhuza ibyuma byifashishwa mu gutunganya imashini - cyane cyane iyo igice ari inzu ya pompe ya cobalt-alloy yubatswe ku kabari 350 cyangwa umubiri wa AMS 5387 usaba ± 0.02 mm GD&T kubahiriza.
Impamvu Shell Mold Casting Itanga Aho Izindi nzira Zirwanya
Ibishishwa by'ibishishwa byicara hagati yo guta umucanga no gushora imari: byihuse kuruta ibishashara byatakaye, kwihanganira cyane kuruta umucanga-icyatsi, kandi binini cyane kuruta ibumba ryibumba ryibumba ryinganda ziciriritse. Imbaraga zayo ziri mu gishishwa cyoroshye, gikomeye - ubusanzwe mm 6-10 z'ubugari - gikozwe mu gutwikira icyuma gishyushye (180-250 ° C) n'umucanga wa silika wa fenolike. Igisubizo? Ubuso burangirira kuri Ra 2.5-6.3 mm, kwihanganira umurongo kugera kuri ± 0.3 mm kubiranga munsi ya mm 300, hamwe nibisabwa bike (0.5 ° –1.5 °). Ariko iyo mibare isobanura bike idafite disipuline.
Twabonye abakiriya bahinduka bava kumusenyi bajya kubumba ibishishwa gusa kugirango bahure nintambara mumazu manini ya silinderi-kugeza igihe bamenyeye ko intandaro itari ifumbire, ahubwo ihuza ibice byanditse bidahuye mugihe cyo guteranya ibishishwa. Ku kigo cyacu muri Qingdao, buri shell yashizweho ikorerwa optique ihuza neza mbere yo gufunga. Buri cyiciro cyumucanga usize isuzumwa kugirango ugende neza, imbaraga zingana, hamwe n ibisigara byaka. Kandi buri kintu cyose cyasutswe gikonjesha munsi yikirere cyigenzurwa - nticyazimye ku gahato - kugirango wirinde kwiyongera kwimyuka isigaye mubice byinshi.
Kwishyira hamwe bihagaritse Ntabwo biganirwaho kubutumwa-Ibice byingenzi
Igikonoshwa cyonyine ntabwo cyemeza ko igitutu gikora. Icyangombwa nicyo kibaho mbere na nyuma: ibintu bikurikirana, guhuza ubushyuhe, hamwe na CNC-yiteguye gusobanura. Niyo mpamvu ari ukuri shell mold casting uruganda igomba gutunga - cyangwa kuyobora cyane - urunigi rwuzuye.
- Abakinnyi mbere: Icyemezo cya T800 cobalt gishingiye ku mavuta avanze, yagenzuwe binyuze muri PMI na OES; ingano y'ibinyampeke igenzurwa hifashishijwe metallurgie no gusuka ubushyuhe (± 5 ° C kwihanganira)
- Mugihe cyo gukina: Real-time thermal imaging of mold surfaces to detect localized hot spots that trigger micro-shrinkage in thin-wall sections
- Abakinnyi.
Uku kwishyira hamwe gukuraho amaboko aho drift igereranya. Mugihe umukiriya yatwoherereje inzu ya piston pompe ya pisitori ishushanya hamwe na bore 12 zikomeye hamwe no kwihanganira imyanya 0,015 mm, twafashe intera iri hagati yimfashanyo yo kugabanuka nigikoresho cya nyuma cyimashini mugihe cyo gusuzuma ubwubatsi - atari nyuma yo kugenzura ingingo ya mbere.
Ubuhanga bwibikoresho busobanura imipaka yimikorere
Cobalt-nikel ivanze nka AMS 5387 ntabwo yitwara nkibisanzwe 316 bitagira umwanda. Igipimo cyinshi cyo kunaniza akazi, ubushyuhe buke bwumuriro, hamwe nicyiciro cya karbide icyiciro gisaba ibipimo byo gutoranya byahinduwe kuri * iyo chimie yihariye * - ntabwo ari rusange "superalloy". Ibishingwe bimwe bifata ibinini byose bya cobalt. Ntabwo.
Mubimenyerezo, ibi bivuze guhindura ubugari bwikigero cya mm 1.5 mm bitewe nigice cya modulus, guhindura umuvuduko winjira kugirango wirinde isuri ya nozzles nziza, no gufata igihe cyo gukomera mumasegonda 90 kubacomeka munsi ya mm 40 z'umurambararo. Twakoze imashini zirenga 17,000 AMS 5387 kuva 2021. Buri cyiciro kirimo ubushyuhe bwuzuye, raporo yikizamini cya tensile kuri ASTM E8, hamwe namafoto ya microstructure yerekana ikwirakwizwa rya karbide ya eutectic-nta cluster yitaruye hafi yinjirira mumarembo.
Urwo rwego rwo kugenzura rutandukanya utanga ibicuruzwa byohereza ibicuruzwa hamwe nuwohereza * ibice byemewe byemewe *. Niba gusaba kwawe kurimo kwipakurura hejuru ya 200 MPa cyangwa guhura na H₂S ikungahaye kuri peteroli na gazi, guhuza ibikoresho ntabwo ari ubushake-ni umurongo wambere wo gukumira kunanirwa.
Guhitamo Umufatanyabikorwa Ukwiye Kubaza Ibibazo Byukuri
A shell mold casting uruganda igomba gusubiza ibi-bitari mubitabo byamamaza, ahubwo mubiganiro byubuhanga:
- Urashobora kunyereka raporo zawe eshatu zanyuma za AMS 5387-harimo ingano yingano, ingano ya karbide%, hamwe nintera ya interdendritic?
- Ugenzura nka-geometrie * mbere yo gutunganya, ukoresheje datum kavukire-ntabwo ari igice cyanyuma gusa?
- Ni ubuhe buremere ntarengwa bw'igice kimwe cya shitingi-cobalt alloys-kandi nigute ushobora kuyobora itandukaniro ryubushyuhe bwumuriro murirwo rwego?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yujuje ibyo bibazo hamwe nuburyo bwanditse, ntabwo amasezerano. Ikigo cyacyo cyujuje ISO gishyigikira ibishishwa bikozwe mu cyuma, ibyuma, bitagira umwanda, hamwe na cobalt-nikel ikora cyane - hamwe no gutunganya CNC, gutunganya ubushyuhe, no kurangiza hejuru yinzu. Ikora hydraulic OEM, ihuza ibikoresho byo hanze, hamwe nabubatsi ba pompe kabuhariwe muri Amerika ya Ruguru, Uburayi, na Aziya y Amajyepfo yAmajyepfo - ntabwo ari umucuruzi, ahubwo ni kwagura itsinda ryabo ryubaka inganda.
Urebye imbere, inganda zizasaba guhuza ibikorwa bya casting hamwe n’inyongera, ibyemezo byagutse byo mu rwego rwa kirimbuzi na API 6A, hamwe no kwemeza impanga zemewe ku buryo bworoshye. Igisekuru kizaza shell mold casting uruganda ntizigana gusa geometrie. Bizahanura imikorere-guhera kuri shell.
