Monel 400 umzi-mveliso womatshini - elo binzana libonisa ngaphezu kokukwazi. Ibonisa ukulungela eyona misebenzi inzima: izindlu ezinoxinzelelo oluphezulu lwehydraulic, izixhobo zempompo zamanzi olwandle, imizimba yevalvu yerhasi emuncu, kunye nezixhobo zaselwandle apho ukuxhathisa umhlwa kuhlangana nolawulo lwejometri yenqanaba lemicron. Senze iinxalenye zeMonel ezingama-400 kubathengi baseHouston, eRotterdam naseSingapore - kwaye ngalo lonke ixesha, umngeni ofanayo uvela kwangoko: ukuqina komsebenzi wezinto eziphathekayo ngexesha lokusika kubangela ukunxiba kwesixhobo esikhawulezayo, ukukrazuka komphezulu, kunye ne-dimensional drift ukuba iiparameters zenkqubo ayivalwanga phambi kokuba i-chip yokuqala ibhabha.
Kutheni iMonel 400 ifuna uhlobo olwahlukileyo lwevenkile echanekileyo
I-Monel 400 ayikho insimbi engenasici. I-67% ye-nickel, i-23% yobhedu, enezongezo ezincinci kodwa ezibalulekileyo zentsimbi, i-manganese, i-carbon, kunye ne-silicon. Amandla ayo okuqina ahlala phakathi kwe-790-965 MPa - ngaphezulu kwe-316 engenasici - kwaye ukuhanjiswa kwayo kwe-thermal yi-23 W/m·K nje. Oko kuchithwa kobushushu obuphantsi kuthetha ukusika ubushushu buhlala buvaleleke kujongano lwesixhobo sokusebenza. Ukufakwa kwe-carbide esemgangathweni kuyasilela ngokukhawuleza. Umoya wokupholisa kufuneka ube noxinzelelo oluphezulu, ujolise, kwaye ungaphazanyiswa. Amazinga okutya ehla nge-30–40% xa kuthelekiswa ne-Inconel 625. Kwaye nakuphi na ukungcangcazela? Iguqulela ngokuthe ngqo kumanqaku encoko ayonakalisa umphezulu wokuvala umphezulu wokutywina okanye iijenali.
Siye sabona abathengi bethumela i-Monel 400 engenanto kwiivenkile ezintathu ezahlukeneyo - kuphela ukubuyisela iinxalenye ezine-ID ejikelezayo engahambelaniyo, i-out-of-spec thread lead error, okanye i-micro-cracking kufuphi neekona zangaphakathi ezibukhali. Oyena nobangela yayingebobuchule bokusebenza. Yayisiqhinga sokusebenzisa izixhobo ngendlela engafanelekanga, ubume bezinto eziziinkozo ezingangqinisiswanga, kwaye akukho nkqubo yokuhlola i-thermal. I-Real Monel 400 machining ifuna ulwazi oludibeneyo lwe-metallurgical - kungekhona nje inkqubo ye-CNC.
Indlela iMonel eyiNyaniso ye-400 yeFactory yokuMachining iLawula ii-variables
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-Monel 400 njengenkqubo - kungekhona ibakala lezinto eziphathekayo. Yonke iodolo iqala nge-batch eqinisekisiweyo ye-ASTM B127 ipleyiti okanye ibha, engqinisiselwe ubungakanani beenkozo (ASTM E112), ukumelana nokukhula kwe-intergranular (i-ASTM G28 Indlela A), kunye nobulukhuni obufanayo kuwo wonke umnqamlezo. Akukho ngaphandle.
Emva koko senza imephu yeendawo ezisebenzayo zenxalenye: ubuso bokutywina bufuna iRa ≤0.4 μm; iibhore ezithwele uxinzelelo zifuna ±0.005 mm ukungqukuva ngaphezu kwe-120 mm ubude; amazibuko anemisonto afuna ifomu epheleleyo yokugaja intambo ngeGo/No-Hamba kuhlolwa ngokwe ASME B1.20.1. Kulapho kuphela apho sikhetha khona izixhobo - i-custom-ground-tipped drills ye-PCD yemingxuma enzulu, i-ceramic wiper ifakela ukugqiba ukupasa, kunye ne-cryogenically treatment mill for milling ye-contour ye-impeller hubs.
Iziko lethu elithobela i-ISO liqhuba amaziko omatshini anee-axis ezininzi axhotyiswe ngexesha lokwenyani lomthwalo wokupholisa esweni kunye nolawulo lweqondo lobushushu lokupholisa oluvaliweyo. Ukuba amandla esixhobo agqitha ngaphaya kwe-12% yesiseko, umatshini uyanqumama ngokuzenzekelayo - akukho ngqikelelo, akukho nkunkuma.
Apho amava ajika abe ziziphumo eziphindiweyo
Umxhasi omnye udinga i-42 ye-Monel 400 yepiston yezindlu ze-cylinder ze-subsea hydraulic systems. Umthengisi wabo wokuqala uhambise iinxalenye ze-17 - zonke aziphumelelanga uvavanyo lokuvuza kwe-helium kwi-300 bar. Unobangela weengcambu? I-Micro-porosity evela kwimiba yesondlo, idityaniswe kukurhabaxa okuthe kwavula indawo engaphantsi komhlaba. Siphinde sayilungisa isakhiwo: saqala ngezithuba zokuphoswa kotyalo-mali (i-AMS 5380 iyahambelana), songeze uvavanyo lwe-ultrasonic ngaphambi komatshini, sisetyenziselwe ukugaya kuphela, kwaye sibambe ukunyamezela kwe-ID yokugqibela kwi-Ø142.000+0.0100 mm kunye nokulandeleka kweCMM ngenani lenxalenye kunye nobushushu.
Enye imeko: Imilomo ye-cobalt ye-cobalt ye-AMS 5387 edityaniswe ne-adapter ye-Monel 400 ye-flange. Zombini izixhobo ziziphatha ngendlela eyahlukileyo phantsi kwebhayisikile ye-thermal. Siqhube ukulinganisa okudibeneyo kwe-thermal, ukuphazamisa ukulungelelaniswa ngokufanelekileyo, kunye nokuqinisekiswa koxinzelelo lwendibano kunye novavanyo lwe-strain-gauge - hayi nje ukukhangela i-dimensional. Yileyo ndlela uphepha ngayo ukungaphumeleli kwintsimi kwi-180 ° C kunye ne-450 psi.
Olu ayilulo ulungiselelo lwethiyori. Zibhalwe kwiiNgxelo zethu zangaphakathi zoQinisekiso lweNkqubo-zifumaneka kubathengi abafanelekileyo kwi-NDA.
Yintoni ngokwenene oyifumanayo kwiMonel 400 yoMzimveliso woMachining
- Isixhobo-isicwangciso sokuqala: Hayi "yiqhube nje kwi-VMC." Siyaqinisekisa ikhemistri, indlela yokuhamba kweenkozo, kunye nembali yonyango lwangaphambili lobushushu phambi kokucaphula.
- Akukho ndleko zifihliweyo zokuphinda zisebenze: Ukuhlolwa kwengqibelelo yobuso kubandakanya ukubonwa kwe-white-layer (nge-SEM / EDS) kwimida enzima yomatshini - kuba i-Monel 400's work-hardened layer ingakwazi ukuqalisa ukukhathala kokutya phantsi kokulayisha i-cyclic.
- Ukuphunyezwa ngokupheleleyo kwe-GD&T: Sitolika isikhundla, iprofayili, kunye nokubiza okuphumayo kungekhona njengokunyamezela - kodwa njengeemfuno zokusebenza. Ukunyamezela kwe-0.02 mm kwisangqa sebholithi akukho malunga nendawo. Imalunga nokuqinisekisa nokuba amandla okubamba ngaphaya kojongano lwegasket ebolileyo.
- Ukulandeleka eyakhelwe-ngaphakathi: Zonke iinqanawa zihamba nesatifikethi esidwelisa inombolo yobushushu ekrwada, uhlaziyo lwenkqubo ye-CNC, i-ID yengxelo ye-CMM, kunye ne-ID yomsebenzisi - hayi nje isitampu.
IMonel 400 yomzi-mveliso ayingomda wethegi yentengiso. Kukuzibophelela kuqeqesho lwesinyithi, ukubekwa elubala kwenkqubo, kunye nokuphendula ngobunjineli. Xa icandelo lakho lisebenza kwi-chloride-rich, high-pressure, zero-maintenance environments - i-compromise ayikho inketho. Ukuchaneka sisiseko. Ukuthembeka kukunikezelwa.
Ukuba iprojekthi yakho elandelayo ye-Monel 400 ifuna uzinzo lwe-dimensional, imfezeko yomphezulu, kunye nokulandeleka okupheleleyo kwezinto - qala kunye neqabane eliphatha i-nickel-copper alloys njengale nto ziyiyo: iinkqubo ezibaluleke kakhulu kwi-mission, hayi isinyithi sesitokhwe.
