Xa iinjineli zicacisa iinxalenye ze-Monel alloy, azikhethi nje izinto eziphathekayo-zibophelele ekuxhathiseni ukubola emanzini olwandle, ukuzinza kwe-thermal kwi-500 ° C, kunye nokunyaniseka komatshini phantsi kokudinwa kwe-cyclic. Kodwa ukukhangela ezo nxalenye ngokuthembekileyo? Kulapho iiprojekthi ezininzi zimisa khona. Siyibonile ngokuphindaphindiweyo: imizobo evunyiweyo, imathiriyeli eqinisekisiweyo, amaxesha amisiweyo-emva koko ulibaziseko ukusuka kwidimensional drift in casting, surface pitting after passivation, okanye i-GD&T callouts etyibilikayo kuhlolo lwenqaku lokuqala. A Inxalenye yomzi-mveliso weMonel alloy ayichazwanga ngesitokhwe se-alloy yayo. Ichazwa ngendlela ephatha ngayo i-gap phakathi kwenkcazo kunye nenyani.
Ukuchaneka akuyonto iKhethekileyo-Yakhelwe kuyo yonke inyathelo lenkqubo
I-Monel 400 kunye ne-K-500 ayenziwanga njenge-304 engenasici. Izinga labo lomsebenzi-nzima li-3 × ngaphezulu. Ukukhutshwa kwe-Chip kuyasilela ukuba amazinga esondlo ehla ngaphantsi kwe-0.08 mm/rev. Ugxininiso lokupholisa kufuneka luhlale ngaphezu kwe-12% ukunqanda i-built-up edge ekufakeni i-carbide. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siqhuba yonke i-odolo ye-Monel ngokusebenzisa umjikelo wangaphambi komatshini wokunciphisa uxinzelelo lwe-thermal-nokuba izithuba ezingenanto-kuba uxinzelelo olushiyekileyo kwi-bar-rolled bar ibangela i-0.015 mm isaphetha kwi-300 mm shaft. Oko kwanele ukulahla indlu yempompo ene-± 0.01 mm yokunyamezela.
Siqinisekisa iibhilithi zeMonel ezingenayo ezinemithombo emibini ye-PMI (ukuchonga imathiriyeli echanekileyo) kunye nemephu yobunzima obuncinci kuwo wonke amacandelo anqamlezayo. Akukho batch ingena kwimveliso ngaphandle kokuqinisekisa umxholo we-nickel uhlala ngaphakathi kwe-63-67% kunye nobhedu ngaphakathi kwe-28-34%. Ngoba? Ngenxa yokuba i-0.5% ye-nickel shortfall yehla amandla esivuno nge-18% kwi-300 ° C-kwaye ngumahluko phakathi kwe-valve ephethe i-10,000 psi okanye ukuvuza ekuqaleni.
Iiseli zethu ze-CNC zisebenzisa iiplatifomu eziqinileyo ze-5-axis kunye nembuyekezo yexesha langempela lokunxiba isixhobo. Kwi-Monel flanges ene-16 × Ø12 mm izibuko ezinentambo, sisebenza ngomatshini yonke imingxuma kwisicwangciso esinye-hayi ezimbini-ukuphelisa utshintsho lwedatum. Ukuhlolwa kokugqibela kusebenzisa i-Zeiss CONTURA G2 CMM kunye neprobes ye-ruby calibrated, kungekhona uthelekiso lwe-optical. Ukugqitywa komphezulu kulinganiswa ngestylus profilometry (Ra ≤ 0.4 µm), hayi iitshathi zeglosi ebonakalayo. Oku akukho overkill. Yindlela esibamba ngayo unyamezelo lwendawo eyi ±0.005 mm kwiijenali zepiston zemibhobho yoxinzelelo oluphezulu lwehydraulic.
Udibaniso oluthe nkqo luSombulula oko kuqhawuka kuKhuseleko lwangaphandle
Abanye ababoneleli bakhuphela ngaphandle, emva koko umatshini kwenye indawo, emva koko ipleyiti kwivenkile yesithathu. I-handoff nganye yongeza ukwahluka: ukuphosa ukushwabana okungalungelelanisiweyo kunye needatum zomatshini, ukugqwethwa konyango lobushushu kungalungiswanga ngaphambi kokuba kugqitywe, ukugquma kobunzima bokugquma iindawo ezibalulekileyo zokutywina. Asiyenzi loo nto.
Iziko lethu elithobelayo le-ISO ligcina imigca yokuphosa utyalo-mali, iindawo zokulahla isanti, kunye namaziko omatshini e-CNC phantsi kophahla olunye. Kwizindlu ze-Monel 400 ze-impeller, sijula sisebenzisa iqokobhe le-ceramic molds kunye nendawo yombethe elawulwayo (<5 ° C), uthele kwi-1,380 ° C ± 15 ° C, kwaye upholile kwi-0.5 ° C / min ukuze ugweme imvula yesigaba se-sigma. Emva koko-ngaphandle kokuqhawula i-vacuum seal-sihambisa i-castings ngokuthe ngqo kwi-ovens yokufudumala i-ovens ye-annealing yesisombululo kwi-980 ° C, ilandelwa ngukucima kwamanzi ngaphakathi kwemizuzwana emi-3. Umatshini uqala kwiiyure ezi-4. Akukho kubonakaliswa komoya. Akukho kuphinda kusebenze kwi-intergranular oxidation.
Oku kudityaniswa kuzisa ukulandeleka onokuthi uphicothe: indawo nganye iphethe ikhowudi ye-QR enxibelelanisa nelogi yayo yokunyibilika, ingxelo yovavanyo lwe-tensile, imephu yokuqina, kunye nerekhodi yokuhlola iCMM. Xa umqhubi we-oilfield yaseMntla Melika efuna i-24 Monel K-500 imizimba yevalve yokutshixa ngokuthotyelwa kwe-NACE MR0175, sazisa iicerti zezinto eziphathekayo-kubandakanywa nomxholo wesulfure. <0.002%-ngeentsuku ze-11 zokusebenza. Hayi iiveki. Iintsuku.
Ukusebenza kwehlabathi lokwenyani kuqala ngoPhononongo lobuNjineli obuyinyani
"Landela nje umzobo" yeyona ndlela ikhawulezayo yokungahambelani. Sifaka ifulegi kwimiba kwangoko-phambi kokusika isinyithi. Kwikota yokugqibela, umxhasi waseYurophu uthumele i-GD&T ye-Monel 400 ejikelezayo edityanisiweyo ene-composite tolerance stack: indawo ye-Ø22 mm yazala xa kuthelekiswa nobuso be-Ø80 mm, kunye ne-perpendicularity yazo zombini kwidatum yesibini, kunye noburhabaxa bomphezulu i-Ra 0.8 µm kwindawo yokukhwelana. Iqela lethu liphendule ngeendlela ezintathu: ukuhlaziya i-datum yesibini ukuze ufanise i-angle yokuphosa idrafti, tshintshela kwi-Monel K-500 ukuze uphucule ubugcisa, okanye wamkele +0.02 mm ekunyamezeleni isikhundla-usahlangabezana neemfuno zokuvavanya ukuvuza okusebenzayo kwi-15,000 psi. Bakhetha uKhetho lwesi-3. Iindleko zezixhobo zehle ngama-37%. Ixesha lokukhokela liye lancipha ngeentsuku ezili-9. Inxalenye iphumelele i-hydrotest kwimizamo yokuqala.
Asithi "ewe" kwiinkcazo ezingenakwenzeka. Siyabuza: Yeyiphi indlela yokusilela? Uxinzelelo lusebenza phi? Yintoni enxiba kuqala? Abasebenzi bolondolozo bazakuyilungisa njani le nto? Yiyo loo nto ipotifoliyo yethu ibandakanya imilomo yealloyi yeMonel yeempompo zenaliti engaphantsi kolwandle, iirola zeshaft ezisembindini zeewintshi zaselwandle, kunye nezindlu zecylinder ezinikwe umjikelo ozizigidi ezingama-200-amacandelo enzelwe isiphumo, hayi nje ukuthotyelwa.
Ukukhetha i-Monel Alloy Part Factory kuthetha Ukukhetha iProfayile yakho yoMngcipheko
Ukuba isicelo sakho sisebenza kwirhasi emuncu, emanzini olwandle, okanye kwi-brine yobushushu obuphezulu, iMonel ayikhethi-yinto efunekayo. Kodwa i-alloy ayiqinisekisi ukusebenza. Umzi-mveliso wenza njalo. Khangela ulawulo olubhaliweyo lwe-metallurgical consistency, uhlolo oluvaliweyo kwinqanaba ngalinye, kunye namaqela obunjineli athetha i-GD & T ye-fluid-hayi isiNgesi kuphela. Ziphephe iivenkile eziphatha i-Monel njenge-generic engenamabala. Banga ubungqina bokulandelwa kwembali ye-thermal. Funa iingxelo ze-CMM-hayi nje "ukuhambelana nezitampu ezikhethekileyo".
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iinqanawa zeMonel kubathengi kuMntla Melika, eYurophu, nakuMzantsi-mpuma weAsia-hayi ngenxa yokuba sithengisa ngogonyamelo, kodwa ngenxa yokuba sisombulula ukungazinzi komgangatho, sithintela ukuqina kwesigaba se-sigma, kunye nokuhambisa iindawo ezisinda kubomi babo benkonzo. Hayi nje ukuhlangabezana nayo. Ukuba iodolo yakho yeMonel elandelayo ifuna ukusebenza ngokutsha, ukulandeleka okugcweleyo, kunye nentsebenziswano yobunjineli-hayi nje ukuvelisa-uyayazi into omawuyenze ngokulandelayo.
