Xa iinjineli zicacisa intsimbi engenastainless intsimbi yokuphosa iivalve zehydraulic valves, izindlu zempompo, okanye i-oyile engaselunxwemeni kunye ne-gas manifolds, abathengi nje isinyithi-bathenga ukuzinza komgangatho phantsi kwe-300 bar, ingqibelelo ye-microstructure emva konyango lobushushu, kunye nokunyamezela kwe-porosity kwiindlela zomthwalo onzima. Yiyo loo nto ukhetha okulungileyo intsimbi stainless utyalo lokugalela iinxalenye umzi-mveliso ayisiyobhokisi yokukhangela-sisigqibo sokunciphisa umngcipheko.
Sibone iiprojekthi ezininzi kakhulu zidodobala xa ukuhanjiswa kudlula uhlolo olubonakalayo kodwa lusilele kuvavanyo loxinzelelo kwindibano yokugqibela. Oyena nobangela? Ubume obungahambelaniyo obuziinkozo obuvela ekuqinisweni okungalawulwayo, okanye ukucinezeleka kwentsalela eyenziwe ngoomatshini kwizindlu ezinodonga olucekethekileyo olujija ngexesha lokudlula komhlaba. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke intsimbi yotyalo-mali iqala nge-AMS 5387-ethobelana ne-traceability yempahla ekrwada-hayi izatifikethi zebhetshi, kodwa iilogi ezigcweleyo zobushushu ezidityaniswe neengxelo zohlalutyo lwe-spectral. Siqinisekisa umlinganiselo wechromium-nickel-molybdenum phambi kokunyibilika, hayi emva koko.
Ukuchaneka Akongezwanga Kamva-Yakhelwe kwiNdlela yeNkqubo
Ababoneleli abaninzi baphatha ukuphosa kunye nomatshini njengamanyathelo alandelelanayo. Sibaphatha njengenkqubo enye eqhubekayo ye-thermal-mechanical. Indlu yesilinda yempompo yepiston eyenziwe kwi-CF8M yentsimbi engatyiwayo ayifumaneki ngoomatshini kwi-5-axis mill *emva* kokuphoswa-iyayilelwa ukususwa kwesitokhwe esincinci *ngexesha* lobunjineli bepateni. Iqela lethu lezixhobo zokusebenza liqhuba ukulinganisa okuqiniswayo (usebenzisa i-MAGMASOFT®) ukuqikelela iindawo ezishushu, emva koko ilungelelanise i-gating kunye nokunyuka ukuze indawo yokugqibela yejometri njenge-cast-cast ngaphakathi kwe-± 0.15 mm ye-GD&T callouts-ngaphambi kokuba kuqale nakuphi na ukusika.
Oku kudityaniswa kuphelisa i-gap yakudala "ye-cast-to-machine": akukho kuphinda kusetyenzwe ngenxa yokwahluka kobunzima bodonga obungalindelekanga, akukho redos ye-CMM yomzuzu wokugqibela ngenxa yokuba umphezulu wedatum utshintshile ngexesha lokupholisa. Kumacandelo afana nemizimba yevalvu yoxinzelelo kunye ne-ASME B16.34 yodidi lwama-900 lokulinganisa, oko kuthetha ukuba sibambe unyamezelo lwendawo yokwenyani ye-0.05 mm kwi-8-mm-diameter yokutywina amabhobho-nakwiindawo ezinomlinganiselo we-3:1 kunye neepaseji ezigrunjiweyo zangaphakathi.
- Ulawulo oluthe ngqo kumgangatho wepateni ye-wax: I-3D-eprintiweyo iipateni eziphambili ezine-25-µm umphezulu ogqityiweyo, ususa ukuguquguquka kokugqitywa kwesandla
- Ukwakhiwa kweqokobhe nge-zircon-silica hybrid slurries-ibalulekile ekufezekiseni iRa ≤ 1.6 µm as-cast surface on 316L impeller vanes
- Ukuqinisekiswa komgangatho ongaphakathi kwinkqubo: Yonke iqashiso ifumana i-100% ye-optical contour yokuskena emva kokususwa kwe-waxing kunye nokudubula kwangaphambili.
- Ukunyangwa kobushushu okudityaniswa neqashiso lokuphosa: Ukufakwa kwesisombululo kwi-1050 ° C ± 5 ° C, kulandelwa kukucima kwamanzi kwiitanki zobushushu obulawulwayo (± 2 ° C)
Kutheni le nto iCobalt Alloys ingqina iStainless Steel Casting
Abanye basenokuthi: “Intsimbi engatyiwa ithe ngqo. Kuba ukuba umzi-mveliso unokuqhubeka uphosa, umatshini, kwaye ugqibe imilomo ye-T800 ye-cobalt esekwe kwi-superalloy-izinto ezinobunzima obungama-45 HRC njenge-cast kunye ne-zero machinability index-ikwazile iimfuno ezisisiseko zentsimbi engenakutyiwa: ulawulo lwe-thermal gradient, ukuhambelana kwe-refractory, kunye novavanyo olungonakalisi.
Siqhuba i-protocol yokuhlola efanayo kwi-304 ye-winch stainless steel centre shaft roller njengoko senza kwiplagi ye-AMS 5387: uvavanyo lwe-ultrasonic nge-ASTM E114, ukuhlolwa kwedayi nge-ISO 3452-2, kunye nokuqinisekiswa okupheleleyo kweekhemikhali nge-OES (i-optical emission spectrometry). Akukho ndlela zimfutshane. Akukho ngqikelelo "eqhelekileyo yokusebenza". Xa abathengi besithumelela imizobo ene-±0.025 mm yokunyamezelana kwesikhundla kwiifitsha ze-Ø6-mm ezibekwe kwi-120 mm ukusuka kwi-primary datum, siphendula ngengxelo yokwenziwa kwe-manufacturability-hayi ikowuti.
Ukunikezelwa kweNtembeko yokwenyani iqala ngokulandelelwa kwexesha lokwenyani
“Ukuhanjiswa ngexesha” akuthethi nto ukuba inxalenye ifika inonyango lobushushu olungabhalwanga okanye iziqinisekiso zemathiriyeli ezingahambelaniyo. Sabela umntu ngamnye owakha i-ID enekhowudi ye-QR ekhethekileyo kulwakhiwo lweqokobhe. Loo khowudi inxulumanisa: iingxelo zovavanyo lokusila izinto ezikrwada, amajikoji amaqondo obushushu eziko ukusuka annealing, CMM iingxelo zokuhlola kunye iimephu ukutenxa umbala-maphu, kunye notyikityo yomsebenzisi kumasango enkqubo engundoqo. Abathengi baseMntla Melika kunye ne-EU bafikelela kule datha bahlala ngokusebenzisa i-portal yethu ekhuselekileyo-kungekhona njengee-PDF ezithunyelwe nge-imeyile ekuthunyelweni, kodwa njengeerekhodi eziphicothwayo zedijithali.
Kwii-odolo ezinomthamo ophakathi (i-50-500 iipcs), ukuhamba kwethu okuthe tye kunciphisa ixesha lokukhokela nge-22% ngokuchasene ne-benchmarks ye-industry-kungekhona ngokungxama, kodwa ngokususa i-loops yokuphinda isebenze. Njani? Siqinisekisa umzobo we-GD&T ngokuchasene nokubanakho ukuphosa *phambi* kokusetyenziswa kwesixhobo. Ukuba umthengi uxela i-Rz 0.8 µm ngaphakathi kwi-12-mm-diameter bore, siyiflegi kwangethuba: i-electropolishing iyasebenza, kodwa ukuhoywa ngoomatshini kwazisa iintanda ezincinci kumabanga angenasici emartensitic. Kungcono ukulungelelanisa i-spec yomhlaba kunokulahlwa kwamalungu angama-47 kwi-QA yokugqibela.
Jonga Ngaphaya koMgangatho weFoundry-Jonga kwiNtsebenziswano yobuNjineli
Utyalo-mali lwentsimbi engenasiphene lufumana ukuthenjwa hayi xa lusithi "ewe," kodwa xa lusithi "nantsi indlela-kwaye nantsi into esinokuyitshintsha." Siye sanceda ii-OEMs ze-hydraulic ze-OEMs zokuyila ngokutsha iivalvu ezininzi ukuze kupheliswe izinyusi ezingaboniyo, ukusika ubunzima bokuphosa nge-18% ngaphandle kokuncama uxinzelelo. Sikhokele abakhi bempompo yaseMzantsi-mpuma Asia nge-ASME iCandelo VIII Div. I-2 yokuthotyelwa kwezindlu ze-duplex ezingenasici ezisebenza kwi-120 ° C kunye ne-250 bar.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayithengisi iicastings. Inika umsebenzi oqinisekisiweyo wokusebenza-ubukhulu, i-metallurgical, kunye nokusebenza. Ukuba utyalo-mali lwakho olulandelayo lwensimbi engenastainless kufuneka uphile ukudinwa okuphezulu, ukuxhathisa i-chloride pitting, okanye ugcine ingqibelelo yokutywina emva kwemijikelo ye-10,000 ye-thermal, qala ngokulandeleka kwezinto, hayi ubungakanani bomyalelo obuncinci. Ukuchaneka akuthenjiswa. Kuqinisekisiwe-indawo yokushisa enye, ingxelo enye yokuhlola, uvavanyo olulodwa loxinzelelo ngexesha.
