Xa indlu yepompo ye-hydraulic iqhekeza phantsi kwe-350-bar yoxinzelelo-okanye i-cobalt alloy nozzle ihluleka emva kweeyure ze-420 zenkonzo ye-sour-gas-iinjineli azisoli ukuyila. Bayibuyisela kwisigqibo esinye: leliphi iqabane le-metalcasting eliphathe ijometri ebalulekileyo, i-microstructure, kunye nozinzo lwe-dimensional.
Kulapho ukuveliswa kwemveliso echanekileyo kuyeka ukuba yinto yorhwebo kwaye ibe sisivumelwano sokusebenza. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sikubonele oku kuqala kwi-178 yohlengahlengiso lwevalve yepompo, ukutshintshwa kweshafti yewintshi engama-92, kunye neebhetshi ze-cobalt ezingama-36 ze-cobalt eziziswe kwii-Tier-1 zezihlanganisi ze-hydraulic system. Konke ukusilela siye sakuhlalutya sabelane ngengcambu efanayo-hayi ukuphosa kakubi, kodwa ukudityaniswa komatshini wokuphosa.
Kutheni "Ukuchaneka" kwi-Metalcasting kuthetha ngaphezu kokunyamezelana
Ukunyamezelana okuqinileyo kuphela akuqinisekisi ukusebenza. Ubukhulu bodonga obuyi-±0.02 mm kwi-piston pump cylinder housing abuthethi nto ukuba isanti-cast microstructure iqulethe i-shrink porosity kufuphi ne-high-stress fillet. Okanye ukuba uxinzelelo olushiyekileyo olusuka ekupholiseni okungalinganiyo luwonga umphezulu weflange emva kokujongana ne-CNC.
Sifumene oku ngexesha lokuqinisekiswa kwe-2022 yemoto yobunjineli esekwe kwi-EU ye-OEM. Umthengisi wabo wokuqala wadibana nazo zonke iifowuni ze-GD & T kwiphepha-kodwa i-31% yezindlu zahluleka ukuvavanywa kwe-hydrostatic kwi-bar ye-400. Iqela lethu lenze imephu yendawo engaphumeleliyo: i-1.8 mm-thick transition rib esecaleni kwe-oyile yokungena. Umba ibingeyompazamo yokwenza. Yayikwinqanaba lokuqiniswa kwendawo yasekuhlaleni ukungahambelani kubumba lwesanti, yandiswe lutshintsho olungundoqo olungalawulwayo.
Isisombululo? Sayila ngokutsha inkqubo yokungena *kwaye* songeza ikhola yokunyuka okupholisayo elawulwayo-emva koko singqinisisiwe ukulinganisa ukuqinisa ngokuchasene nedatha yomfanekiso we-thermal evela ekuthululeni. Isiphumo: Ukusilela kweqanda kwiiyunithi ezingama-12,400. Ukuchaneka kwesinyithi kuqala ngaphambi kokuba i-ladle yokuqala igalelwe.
Izakhono eziNtathu ezingaxoxiswanayo kwiMission-Critical Castings
Ayizizo zonke iindawo ezisisiseko ezinokuvala umsantsa phakathi kwengqibelelo ye-metallurgical kunye nejometri esebenzayo. Ezi zizakhono ezintathu esizivavanya ngokungqongqo-phambi kokucaphula inxalenye enye:
- Ungqamaniso lwenkqubo yezinto eziphathekayo: Ukuphosa i-cobalt-nickel alloys njenge-T800 okanye i-AMS 5387 ayikho malunga nokugalela isinyithi esishushu. Ilawula ukwakheka kweenkozo ngokusebenzisa i-melt superheat echanekileyo (1420-1445 ° C), i-mold preheat (220-240 ° C), kunye namazinga okupholisa emva kokugalela. Sifaka yonke ipharamitha-kwaye siyinxulumanise ne-tensile elongation kunye nobunzima bokusasazwa kubushushu ngamnye.
- Ulawulo lwekhonkco lomgangatho: Ukuphoswa kwentsimbi kunokubamba ± 0.3 mm njenge-cast, kodwa oko akunamsebenzi ukuba i-bore yokugqibela eyenziwe ngomatshini ifuna ± 0.015 mm. Sakha i-stack tolerance stacks e-akhawunti yokuphosa i-shrinkage, i-machining tool deflection, kunye nokwandiswa kwe-thermal ngexesha lokunyanga ukushisa-konke kuqinisekisiwe nge-CMM scans kwizigaba ezintathu: njenge-cast, i-semi-finished, kunye neyokugqibela.
- Ukulandelelwa kwebhetshi epheleleyo-hayi nje amanani alandelelanayo: Xa umthengi ebika ukugqitywa komphezulu ongahambelaniyo kwiiplagi ze-cobalt alloy, sifuna ngaphezu kwenani lobushushu. Sitsala izigodo zesithando somlilo, iirekhodi zebhetshi yesibophelelo sesanti, amaxesha okuhlala e-oveni angundoqo, kunye nokufuma okukhoyo ngexesha lokudibanisa ukungunda. Elo nqanaba lokulandela umkhondo lithintele ukungaphumeleli okuphindaphindiweyo kwiprojekthi yempompo ye-oyile yase-Asia-mpuma ye-Asia kwikota yokugqibela.
Iindleko zokwenyani zeZisombululo zeMetalcasting "eziqhelekileyo".
Abanye abathengi bakhetha ukuphoswa kwexabiso eliphantsi ngokusekelwe kwixabiso le-kg nganye. Kodwa ekusebenzeni, bahlawula kwenye indawo:
- I-Re-machining scrap: i-12-19% ilahleko yesivuno kwi-casting iron castings xa izibonelelo zomatshini zingalungiselelwanga ukuguquguquka komhlaba.
- Ukungaphumeleli kwentsimi: Isiseko sempompo yensimbi engenasiphene eqhekekileyo sixabisa indawo yokusebenzela yamanzi kamasipala waseMntla Merika i-$217,000 ngexesha lokuphumla elingxamisekileyo—singabali ukutshintshwa kwabasebenzi.
- Ukulibaziseka koyilo lokuphinda: Ngaphandle kwengxelo yokwenziwa kwangaphambili, i-68% yeeprototypes zokuqala zabathengi zifuna utshintsho lwejometri. Sifaka iflegi yemimandla yomngcipheko-njengeembambo ezinodonga olucekethekileyo ngaphantsi kwe-2.3 mm okanye i-engile yokuyila phantsi kwe-0.8 °-ngexesha lokuphonononga umzobo, kungekhona emva kokusikwa kwesixhobo.
Indlela yethu yokwenziwa komatshini womxube wehlisa ixesha lokukhokela nge-34% ngokomndilili. Ngoba? Kuba sisebenza ngomatshini indawo yokutywina ebaluleke kakhulu *phambi* konyango lokugqibela lobushushu-sinqanda ukugqwetheka okunyanzela ukuphinda kusetyenzwe kwiindawo ezigqityiweyo.
I-Metalcasting Eyokulinganisa Ngaphandle Kokuncama Ingqibelelo
Ukuveliswa komthamo ophakathi kubonisa ubuthathaka obungabonakaliyo kwiiprototypes. Ukuhamba ngebhayisekile ngokushushu ngaphaya kwama-500 okugalela kutshintsha ukusebenza kwesibophelelo sesanti. Ukungcangcazela kokungunda kuyaqokelelana. Ukudinwa komsebenzisi kuchaphazela ukuhambelana kokubeka okungundoqo.
Siyayichasa le nto ngolawulo oluthambileyo lokuhamba komsebenzi: amaxesha omjikelezo wokubumba avumelaniswe kwi-binder cure logs, i-automated core-setting jigs enempendulo ye-positional, kunye ne-in-process ultrasonic scanning kwi-100% yentsimbi kunye ne-stainless steel castings ngaphezu kwe-15 kg. Kwii-alloys ze-cobalt, songeza uhlalutyo lwe-spectral kubushushu besithathu ukuqinisekisa i-nickel-chromium-molybdenum ratios ngaphakathi kwe-± 0.15% ye-spec.
Oku asikobunjineli obugqithisileyo. Yindlela esihambisa ngayo i-99.82% isivuno sokuqala sokupasa kwimizimba ye-valve yoxinzelelo-ngelixa sigcina ukulandelwa kwezinto ezipheleleyo ukuya kwi-ingot lot kunye ne-ID yesithando somlilo.
Ukuchaneka kwe-metalcasting kusombulula iingxaki zokwenyani: ukuthintela ukuvuza okuyingozi kwiinkqubo zoxinzelelo oluphezulu, ukwandisa ubomi benkonzo kwiindawo ezirhabaxa, ukwenza uyilo lobunzima obulula ngaphandle kokunciphisa amandla. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha loo mandla-kungekhona njengebango lokuthengisa, kodwa njengenkqubo ebhaliweyo, enokuphicothwa, ephindaphindiweyo. Xa icandelo lakho lisebenza apho ukungaphumeleli kungeyiyo inketho, intsimbi imele ibe sisiseko—kungekhona ingcamango yamva.
