Ukufakwa kwe-nickel kunikezela ukuxhathisa okukhethekileyo kubushushu, ukubola, kunye nokunxiba-iyenza ibaluleke kakhulu kwiivalvu zehydraulic, izindlu zempompo ezinoxinzelelo oluphezulu, kunye neoyile kunye nezixhobo zegesi ezantsi. Kodwa ukuzuza isandi, ukuphoswa kwe-nickel okuzinzileyo akukona nje ukugalela isinyithi esityhidiweyo kwisingundo. Siphose ngaphezulu kwe-12,000 ye-nickel alloy alloy ukusukela ngo-2018-kubandakanya i-AMS 5387 cobalt-nickel yempompo ye-cobalt-nickel kunye ne-T800-based winch shafts-kwaye konke ukusilela kusifundisa into echanekileyo. Esi sikhokelo sichaza into esebenzayo, yintoni engasebenziyo, kwaye kutheni.
Qala nge-Right Alloy-kwaye uyiqinisekise
Ukukhutshwa kwe-nickel kuqala ixesha elide ngaphambi kokuba iziko likhanyise. Iialloys ze-nickel azitshintshi. Usebenzisa IN718 apho umthengi ukhankanye i-UNS N06625? Oko akusiyo indawo-yingozi yokusebenza. Sakhe safumana imivalo eluhlaza ebhalwe "Inconel 625" evavanye i-0.8% ephantsi kwi-molybdenum. Iziphumo ezifunyenweyo ziye zaphumelela uvavanyo olubonakalayo kodwa zasilela kuvavanyo lwesitshizi setyuwa kwiiyure ezingama-72-hayi i-1,000. Ukuphoswa kwe-nickel yokwenyani kuqala ngeengxelo zovavanyo lokusila eziqinisekisiweyo (ii-MTRs), uqinisekiso olupheleleyo lwe-elemental nge-OES spectroscopy, kunye nokulandeleka kwinombolo yobushushu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke ibhetshi yenikeli okanye i-cobalt-nickel ifumana ukuqinisekiswa kwemathiriyeli engenayo ngokuchasene ne-ASTM B446 okanye i-AMS 5708. Akukho ngaphandle. Ukuba umthengisi wakho utsiba eli nyathelo, inkqubo yakho yokulahla sele ithotyiwe.
Lawula Ukungunda—Kungekhona Nje Ngesinyithi
Iialloyi zenickel ezinyibilikisiweyo zifuna uzinzo olugqithisileyo lobushushu. Iimbumba zesanti ziyaqhekeka. Investment iqokobhe zotyalo mali. Siye sabona amaqela e-porosity enziwa kungekhona kwi-gas entrapment-kodwa evela kwi-silica reaction kunye ne-nickel oxide kwi-1,350 ° C. Ukulungiswa? Sebenzisa amaqokobhe otyalo-mali adityaniswe ne-zircon kwi-nickel castings enodonga olucekeceke phantsi kwe-5 mm ubukhulu bodonga. Ukugalela isanti, kunqande isanti eluhlaza ebotshelelwe ngodongwe. Tshintshela kwi-no-bake phenolic urethane binders kunye ne-ceramic wash coatings-ihlolwe ukumelana> 1,400 ° C ngaphandle kwe-micro-cracking. Okubaluleke kakhulu: ukufudumala iimbumba kwi-250-350 ° C * kwaye ubambe * i-≥90 imizuzu. Ukutsiba ixesha lokufunxa kubangela ukubanda, ukondla okungaphelelanga, kunye nokuvalwa okubandayo—ingakumbi kwiijometri ezintsonkothileyo ezifana nezindlu zepiston pump cylinder ezinemijelo yokupholisa yangaphakathi.
Yiphephe Le Migibe Mithathu—Rhoqo
- Ukuyijongela phantsi imbuyekezo yokucutheka. I-nickel alloys iyancipha i-2.1-2.5% ngokulandelelana-phantse intsimbi engwevu ephindwe kabini. Iimodeli ze-CAD ezilinganiswe kwi-2.3% zisavelisa i-+0.12 mm ukutenxa kwiimpawu ze-300 mm ukuba ukwandiswa kwe-thermal ye-pattern imathiriyeli ayifakwanga.
- Ukutsiba isisombululo se-annealing phambi komatshini. Izakhiwo ze-nickel ze-As-cast ziqulethe ulwahlulo lwe-dendritic kunye noxinzelelo olushiyekileyo. Ukucoca phambi kokuba unyango lobushushu lukhokelela kwi-warpage, ingxoxo, kunye nokunxiba izixhobo zangaphambi kwexesha-nokuba ufake i-carbide. Zonke ii-AMS 5387 zethu kunye ne-T800 castings zifumana isisombululo esipheleleyo (1,150 ° C / 2 hrs / argon quench) phambi komsebenzi we-CNC.
- Ukucinga ukuba "nickel" ithetha "non-magnetic." Ezinye ii-alloys ze-nickel-copper (umzekelo, i-Monel 400) zigcina umbane omncinci emva kokuphosa. Ukuba isicelo sakho sifuna i-MRI-grade non-magnetism, khankanya i-ASTM A479 Grade N04400 kunye <0.005 max μr-kwaye uqinisekise nge-gaussmeter post-heat-treat.
Kutheni uHlanganiso oluthe nkqo lutshintsha iziPhumo
Uninzi lweentsilelo zokuphosa i-nickel zenzeka kwiindawo eziphathwayo: isiseko sokucoca ubushushu, isicoci sobushushu kwingcali yoomatshini, igcisa likamatshini ukuya kumgqibezeli. Silawula zonke izigaba ezine-kwindawo enye eqinisekisiweyo ye-ISO 9001. Xa umthengi efuna imizimba yevalve yoxinzelelo kunye ne-± 0.025 mm ukunyamezela kwe-ID kwi-120 mm bore, siphosa, isisombululo-i-annealed, i-rough-turned, i-age-hard, i-bored-bored, kunye ne-honed-konke phantsi kophahla olulodwa. Isiphumo? 98.7% isivuno sokuphumelela kokuqala. Thelekisa oko kuhambo lwangaphandle apho umthengisi ngamnye esebenzisa ezakhe ii-dimensional offsets, iimbali ezishushu, kunye neendlela zokulungiselela umphezulu. Ukuguquguquka kweekhompawundi. Imodeli yethu ethe nkqo isusa i-interface drift, iqinisekisa ukuqhubeka kwe-microstructure, kunye nokutshixa ukuthotyelwa kwe-GD&T ukusuka ekukhupheni idatha ukuya kwingxelo yokugqibela yokuhlola.
Ukujonga okokugqibela: Buza le mibuzo mihlanu ngaphambi kokuphosa
Ngaphambi kokuba uvume i-nickel casting quote-okanye usayine kuyilo-qinisekisa ezi ngongoma zintlanu:
- Ngaba ibakala le-alloy lihambelana nommandla wenkonzo-kungekhona nje amandla okunyamezela, kodwa ukuqhekeza ubomi kwiqondo lokushisa lokusebenza?
- Ngaba izinto zokubumba kunye neeprofayili zokutshisa kwangaphambili zibhaliwe-azicingelwanga?
- Ngaba umthengisi uyaqinisekisa imathiriyeli engenayo *kwaye* agcine ukulandeleka kobushushu obugcweleyo?
- Ngaba isisombululo se-annealing sicwangcisiwe *phambi* kwawo nawuphi na umsebenzi-kwaye kungqinwe ngobulukhuni kunye neengxelo zobungakanani beenkozo?
- Ngaba uhlolo lwe-CMM lwenziwa kwiindawo ezipholile ngokupheleleyo, ezizinzile-akukho shushu ngaphandle komgca?
Ukwenziwa kwe-nickel akuyona inkqubo yokuthengisa. Yinkontileka ye-metallurgical phakathi kwenjongo yoyilo kunye nenyani ebonakalayo. Konke ukutenxa-nokuba kwi-chemistry, iprofayili ye-thermal, okanye ixesha lokulinganisa-kushiya umnwe ekusebenzeni. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-nickel casting njengobunjineli obubalulekileyo, kungekhona ukugalelwa kwesinyithi. Kuba xa impompo yakho isebenza kwi-4,000 psi okanye ivalve yakho itywina igesi emuncu, akukho mda “wokuvaleka ngokwaneleyo.”
