Ukumelana nobushushu obuphezulu be-corrosion ayikhethi-yinto esisiseko. Xa umbhobho wokuphuma ubengezela bubomvu obubomvu, xa izindlu zeiturbine zijikeleza phakathi kwe-700°C kunye nokuphola ngokukhawuleza, okanye xa inkqubo eneasidi egcweleyo itya ngendlela esemgangathweni ye-stainless nge-0.1 mm/ngonyaka, lunye kuphela udidi lwemathiriyeli olubamba umgca: ii-nickel-chromium superalloys ezifana ne-Inconel. Kodwa umgangatho wezinto eziluhlaza kuphela awuqinisekisi ukusebenza. Ukuthembeka kwehlabathi lokwenyani kuxhomekeke kwindlela i Inxalenye ye-inconel yenziwe-hayi nje into eyenziwe ngayo.
Kutheni "Inconel" Inganelanga-Imalunga neMicrostructure eLawulwayo
Siye sabona iiprojekthi ezininzi kakhulu zisilela kungekhona ngenxa yokhetho lwe-alloy, kodwa ngenxa yokucwangciswa okungalawulwayo. Umxhasi kwi-oyile yoLwandle lwaseNyakatho kunye negesi echazwe kwi-Inconel 625 yendlu yokulawula i-valve ephezulu-emva koko wafumana iindawo ezinokuhamba okuziinkozo okungahambelaniyo, i-micro-porosity kufuphi neendawo ezichaphazelekayo ngubushushu, kunye nokuqhekeka kwangaphambi kwexesha emva kwe-4,200 imijikelezo yokushisa. Unobangela weengcambu? Umthengisi usebenzise i-generic CNC machining kwi-as-cast blanks ngaphandle kokunciphisa uxinzelelo okanye ulawulo lokuqinisa oluyalathiso. I-Inconel ixhathisa i-oxidation-kodwa kuphela ukuba isakhiwo sayo se-dendritic sihlala sifana, i-carbide yayo yokusabalalisa intle kwaye ihlakazekile, kunye neengcinezelo zayo eziseleyo ngaphantsi kwe-120 MPa.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke Inxalenye ye-inconel iqala nge-AMS-certified billet okanye i-investment-cast preform-ungaze ulahle isitokhwe esinyibilikisiweyo. Siqinisekisa i-chemistry nge-OES phambi komatshini, ukulandelela iqashiso ngalinye ukusuka kwi-log yesithando ukuya kwingxelo yokugqibela yeCMM, kwaye sisebenzise isisombululo se-annealing kwi-1,095 ° C ± 5 ° C kunye nokulawulwa kwe-argon elawulwayo. Yiloo ndlela esibamba ngayo ubungakanani beenkozo kwi-ASTM E112 iNqanaba 5-6 kwiijometri ezintsonkothileyo ezifana nezindlu zepiston pump cylinder-amacandelo abona i-350 bar pulsation kunye ne-650 ° C exhaust backflow.
Apho uMgangatho woMatshini usilela-kwaye yintoni esebenzayo endaweni yoko
I-Inconel 718 inqumla kwi-1/3 ireyithi yokutya ye-316 engenasici. Ubomi besixhobo behla nge-70% rhoqo nge-50 ° C yonyuka ngaphezu kwe-600 ° C yobushushu besixhobo. Ezinye iivenkile ziphendula ngokucothisa yonke into—uze uzibuze ukuba kutheni amaxesha okukhokela anwenwele ukuya kwiiveki ezili-14 kwaye uburhabaxa bomphezulu bubetha iRa 3.2 µm endaweni yeRa 0.8 efunekayo.
Senza izinto ezintathu ngokwahlukileyo:
- Hybrid casting-machining workflows: Ukulungiselela iziseko zempompo kunye nemizimba yevalvu, senza iimilo ezikufutshane-netha zisebenzisa i-ceramic shells molds-ukunciphisa ixesha lomatshini ngama-65% ngelixa ugcina ulungelelwaniso lwenkozo ecaleni kwendlela yomthwalo.
- Multi-axis adaptive milling: I-Mazak INTEGREX i-200S yethu isebenzisa imbuyekezo yexesha langempela lokuphambuka kwesixhobo ngexesha lokugaya i-Inconel 601 ye-nozzles-ukugcina ukuguquguquka kodonga phantsi kwe-± 0.05 mm nakwi-12: 1 ubunzulu ukuya kububanzi.
- Uzinzo lwasemva kwenkqubo: Wonke omatshini Inxalenye ye-inconel ifumana i-vibratory stress relief (VSR) kwi-28 Hz kwimizuzu ye-45 ngaphambi kokuhlolwa kokugqibela-ukusika ukugqwesa kwizindlu ezinqabileyo ezinqabileyo nge-80% ngokubhekiselele ekugugeni kwe-thermal yedwa.
Oku akuyothiyori. Yindlela esiye sahambisa ngayo i-217 AMS 5387 i-cobalt-alloy 6 yepompo yepompo kwi-OEM ye-hydraulic yaseJamani-enokuthotyelwa kwe-GD & T Zone egcinwe kwi-± 0.015 mm kwii-datums ezi-12 ezibalulekileyo, ukusebenza kwakhona kwe-zero, kunye nokulandeleka okupheleleyo kwenani elinyibilikayo kunye nezigodo zomjikelezo wokushisa.
Iindleko ezifihliweyo zoKhetho lweMathiriyeli "elungile ngokwaneleyo".
Ezinye iinjineli ziyasilela kwi-Inconel 600 kwindawo etyebileyo ngesalfure. Iyasebenza—inyanga ezintandathu. Emva koko uhlaselo lwe-intergranular luqala kwi-weld HAZs. Abanye bachaza i-Inconel 625 yenkonzo ye-chloride-ukungahoywa kwayo kwi-corrosion ye-crevice engaphantsi kwe-pH 4.5 kunye ne-80 ° C.
Asifanisi nje ialloys kwiitshathi zobushushu. Senza imephu imvulophu egcweleyo yokusebenza: iqondo lobushushu obuphezulu, izinga lerempu yobushushu, isantya solwelo, i-pH, i-chloride ppm, kunye neprofayile yokulayisha ngoomatshini. Kwiimpompo ze-injection yekhemikhali ye-offshore, sitshintshe umxhasi ukusuka kwi-Inconel 625 ukuya kwi-Inconel 686-ukongeza i-3% ye-tungsten kunye ne-1.6% ye-niobium-ukwandisa ubomi benkonzo ukusuka kwi-9 ukuya kwiinyanga ze-34 kwi-120 ° C, i-15,000 ppm Cl⁻ brine. Kwi-high-wear i-winch center shaft rollers kwiimoto zobunjineli, sisebenzisa i-T800-based based cobalt-nickel overlays esetyenziswe nge-plasma transfer arc-ukufikelela kwi-62 HRC yobunzima bomhlaba kunye ne-zero delamination emva kwe-2.1 yezigidi ze-torque.
Ukukhetha i-material ayiloluhlu lwedatha. Luthethathethwano lwesinyithi-nendawo okungqongileyo, ijometri yakho, kunye neendlela zakho zokungaphumeleli.
Ukusuka kuMzobo ukuya kuHambiso: Yeyiphi iNdawo ye-Inconel ethembekileyo efunekayo ngokwenene
Ukuthembeka kuqala ngaphambi kokuba i-chip yokuqala ibhabhe. Sijonga yonke i-callout ye-GD&T-hayi ukuthobela, kodwa ukwenza. Isikhundla sokunyamezela kwe-Ø0.02 mm kwi-flange ye-300 mm? Inokwenzeka-kodwa kuphela ngemiphezulu yedatum yomhlaba kunye nokuqinisekiswa kwe-CMM enomoya. Sibadweba kwangoko. Sikwavavanya ukutsaleka kwi-Inconel 718 diaphragms etsalwa ngokunzulu kusetyenziswa ulungelelwaniso lwemifanekiso yedijithali (DIC), siqikelela ubungakanani bendawo ngaphambi kokuba isixhobo sisikwe.
Indawo yethu ehambelana ne-ISO iphethe ikhonkco elipheleleyo: i-sourcing eqinisekisiweyo yezinto eziluhlaza, ukuchithwa kotyalo-mali kwiipaseji zangaphakathi eziyinkimbinkimbi, i-5-axis CNC yeempawu zangaphandle zokunyamezela, ukunyanga ukushisa kwe-vacuum, kunye nokugqitywa komphezulu-kuquka i-electropolishing yeendibano zempompo zamachiza kunye neengubo ezilukhuni-anodized ze-winch gears zaselwandle. Ukuhlolwa kokugqibela kubandakanya ukuvavanywa kwedayi nge-ASTM E1417, ukuskena kwe-ultrasonic nge-ASTM E1961, kunye novavanyo loxinzelelo olusebenzayo kwi-1.5 × uxinzelelo lokusebenza.
Ukuba ufuna i Inxalenye ye-inconel esindayo-hayi nje ilingana-qhakamshelana QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ngqo. Siphendula imibuzo yobunjineli kwiiyure ezi-4 zomsebenzi. Sabelana ngee-certs zezinto eziluhlaza ngaphambi kokuqinisekiswa kwe-odolo. Kwaye sithumela iingxelo ezinobukhulu kunye nomthwalo ngamnye.
