I-Nickel 400 i-alloy parts ihambisa ukuchasana okungenakulinganiswa kwi-chloride yoxinzelelo lwe-corrosion cracking, i-pitting yamanzi olwandle, kunye neendawo ze-alkali ze-caustic-imeko apho iintsimbi ezingenasici zihluleka ngokuthula kunye nentlekele. Siye sazibonela ngawakho: i-hydraulic manifold in a North Sea control system yaqhekeka kwiinyanga ze-18-kungekhona kuxinzelelo, kodwa ukusuka kwi-chloride epholileyo ukungena kwi-micro-porosity kwi-316 engacaciswanga kakuhle kwizindlu. Ukutshintshela kwi-Nickel 400 ye-alloy part geometry, ngokuqiniswa okulawulwayo kunye nokunciphisa uxinzelelo lwasemva komatshini, ubomi benkonzo eyandisiweyo ukuya kwiminyaka eyi-12. Ayingomsebenzi wethiyori leyo. Oko kukuthembeka okuqinisekisiweyo kwintsimi.
Kutheni i-Nickel 400 ime ngokwahlukileyo kwiMingeni ye-Corrosion yeHlabathi yokwenyani
I-Nickel 400 (i-UNS N04400, i-Monel 400) ayikho nje "i-resistant-resistant." Ikhuselekile ngokukhethayo. I-67% ye-nickel-30% isiseko sobhedu senza i-self-self-healing, i-adherent oxide layer echasene ne-flow-accelerated corrosion in brine, hydrofluoric acid, kunye ne-sulfuric acid engaphantsi kwe-70% yoxinaniso-nakwiqondo lokushisa eliphakamileyo. Ngokungafaniyo ne-duplex steels stainless, ayibonisi i-sigma-phase embrittlement emva kokuvezwa kwexesha elide ngaphezulu kwe-500 ° F. Ngokungafaniyo ne-titanium, iyamelana nokunciphisa i-asidi ngaphandle kokukhuselwa kwe-cathodic yentsimbi. Kodwa ukungakhuseleki kufuna ukuchaneka: i-porosity, ukwahlukaniswa kwe-intermetallic, okanye uxinzelelo lwe-machining olushiyekileyo lunokudala iiseli zegalvanic zasekhaya. Yiyo loo nto isiqinisekiso sezinto eziluhlaza sisodwa asanelanga. Udinga unyango lobushushu obulandelekayo, ubume obuziinkozo obuqinisekisiweyo, kunye nokuthembeka komphezulu oqinisekiswe yi-Nital etch kunye ne-SEM yohlalutyo olunqamlezayo-kungekhona nje ii-certs ze-mill.
Apho ukuFaneka okuMgangatho kusileleyo-kwaye ubuNjineli obuchanekileyo bungena
Abanye banokuphikisa ukuba isitokhwe se-nickel 400 esingekho kwi-shelf sisombulula ingxaki. Nangona kunjalo, uninzi lwezicelo ezikumgangatho ophezulu zifuna ijometri engenakwenzeka ngokuguquka okuqhelekileyo okanye ukugaya kuphela. Cinga ngendlu yesilinda yempompo yepiston yenaliti ye-oyile engaselunxwemeni: iitshaneli zokupholisa zangaphakathi ezinqumlana kwii-angles ezingama-47°, ubukhulu bodonga busuka kwi-12 mm ukuya kwi-3.2 mm phakathi kwe-50 mm yohambo, kunye neendawo zokutywina ezifuna i-Ra ≤ 0.4 µm. I-CNC eqhelekileyo kwi-Nickel e-annealed 400 ibangela ukuqina komsebenzi, ukuchithwa kwesixhobo, kunye nokuphazamiseka kwe-thermal-okukhokelela kwi-taper engaphandle kwe-spec kunye nokuvuza kwetywina kwangaphambi kwexesha. Sisombulula oku ngokudibanisa utyalo-mali lwemilo ekufutshane-netha (ukunciphisa ixesha lomatshini nge-65%), kulandelwa yi-axis emihlanu ngaxeshanye yokusila kunye nokuhanjiswa kwe-cryogenic okupholisa kunye nokuqinisekiswa kwe-CMM kwi-setup nganye. Isiphumo? Uzinzo lweDimensional ngaphakathi kwe ± 0.015 mm ngapha kwe-300 mm ubude-kunye nokusilela okuxelwe kwintsimi engama-42 kulo lonke elaseNorway, e-UAE, naseLouisiana.
IiMfuno ezine ezingaXoxekiyo kwiMishini yeNikel eCritical 400 yezahlulo zengxubevange
- Ukulandelelwa kweMathiriyeli ukuya kwinqanaba lobushushu: Yonke inxalenye iphethe amaxwebhu apheleleyo-inombolo yesithando somlilo, uhlalutyo lwe-ladle, ubushushu besisombululo se-anneal / ixesha, kunye nokuqinisekiswa kokuqina kwe-Rockwell B-kungekhona nje inombolo ye-UNS.
- Ulawulo lweMicrostructure: Akukho ukukhula kwedendritic okungalawulwayo. Zonke iicastings ziphantsi kweliso lokuqinisa ulwalathiso; onke amacandelo amatshini adlula uvavanyo lwe-ultrasonic nge-ASTM E114 yokuyeka ukuqhubekeka.
- uQinisekiso lweMfezeko yoMphezulu: I-Ra, i-Rz, kunye ne-Rsk ilinganiswe-ayicingelwanga. Ubuso bokutywina obubalulekileyo bufumana i-interferometry yokukhanya okumhlophe; amazibuko anemisonto afumana ukuskena iprofayili yomsonto ngokwe-ISO 15510 nganye.
- Ukuqinisekiswa kweFit esebenzayo: Hayi nje idimensional check. Iivalve zoxinzelelo ezidibeneyo zifumana uvavanyo lokuvuza kwe-helium kwi-1.5 × uxinzelelo lokusebenza; ii-winch shaft rollers ziqhuba ibhalansi eguqukayo kwi-3,200 RPM phambi kokuthunyelwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.: Ukwakha Oko Abanye Bakucaphula “njengengenzeki”
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yenza iinxalenye ze-Nickel 400 ze-alloy apho ukungaphumeleli kuthetha ixesha lokunciphisa, ukukhululwa kwendalo, okanye ukuthobela ukhuseleko. Indawo yabo ehambelana ne-ISO e-Qingdao iphethe ikhonkco elipheleleyo-ukusuka kwi-AMS 5387-ethobelayo ekufumaneni izinto ezikrwada kunye ne-vacuum-investment casting, ukuya kwi-multi-axis CNC machining kunye nembuyekezo yexesha langempela le-thermal, ukuqinisekiswa komsebenzi wokugqibela. Bahlala bevelisa amacandelo angengawo aqhelekileyo afana nemizimba yevalve ye-cobalt-nickel ehlanganisiweyo enezihlalo ezidityanisiweyo ze-Nickel 400, okanye i-T800-alloy pump housings ene-Nickel 400 fluid-contact liners-ijometri ezikhatywayo ngabathengisi abathathu ngaphambi kokufikelela kuphononongo lwabo lobunjineli. Amandla abo alele ekwaleni ukwahlula i-metallurgy kumatshini: bahlengahlengisa iiparamitha zokusika ngokusekwe kwiimephu zobunzima obuncinci, hayi iitafile ze-generic feed-and-speeds tables. Xa i-OEM yaseYurophu idinga imilomo ye-Nickel engama-400 emile okwesiqhelo ye-17 yesityalo sokukhupha ityuwa kwi-high-velocity brine header, i-QINGDAO QIANGSENYUAN yazisa imvume yenqaku lokuqala kwiintsuku ezili-11-kungekhona iiveki-ngokusebenzisa ukusikwa kwesilingo kwiikhuphoni zovavanyo eziqinisekisiweyo ezivela kwindawo efanayo yobushushu.
I-Nickel 400 ye-alloy inxalenye yokusebenza ixhomekeke ekusebenzeni-kungekhona nje ukuchazwa. Khetha amaqabane aphatha amaphepha edatha yezinto njengeendawo zokuqala, hayi imigca yokugqiba. Ngubani oqinisekisa ukuxhathisa kwe-corrosion ngetyuwa-spray + i-electrochemical impedance spectroscopy-kungekhona nje ukuhlolwa okubonakalayo. Ngubani oqondayo ukuba i-0.002 ″ ukunyamezela kwi-12″ yobuso be-flange ayithethi nto ukuba uxinzelelo olushiyekileyo luyayigqwetha ngexesha lofakelo. Kwixesha elizayo isicelo sakho sifuna okungaphezulu kunokumelana nokuthotywa kwegama, jonga ngaphaya komgangatho wealloyi. Jonga indlela eyenziwe ngayo, ivavanywa, kwaye ilandwa ngayo. Kulapho ukuthembeka kokwenene kuqala khona-kwaye apho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihambisa.
