Xa iinjineli zicacisa ukugalelwa kwesanti yensimbi engenastainless kwi-high-pressure hydraulic valves okanye i-offshore pump housings, abakhethi nje izinto eziphathekayo-babheja ngokuzinza kwe-dimensional, ukumelana nokubola, kunye nokuhambelana kwe-microstructural phantsi koxinzelelo lwehlabathi lokwenene kunye noxinzelelo lomatshini. Yiyo loo nto ukhetha okulungileyo steel stainless sand casting Foundry factory ibaluleke ngaphezu kokucaphula ukunyamezelana ephepheni. Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngabaseki abaphatha ukugalelwa kwesanti njengenkqubo yemveliso kunoqeqesho lwesinyithi.
Ukugalelwa kwesanti yentsimbi engatyiwayo akufani nentsimbi engwevu okanye ialuminiyam. Indawo yayo ephezulu yokunyibilika (1400–1500°C), ubuntununtunu kwisantya sokupholisa, kunye notyekelo lokuya kulwahlulo phakathi kwe-interdendritic kufuna ulawulo oluluqilima phezu kokungena kokungunda, i-binder chemistry, ubushushu obuthululwayo, kunye nexesha lokushukuma. Ukutenxa nge-2°C kwi-preheat kunokubangela i-microporosity kwimizimba yevalvu ye-ASTM A351 CF8M. I-0.3 mm engahambelaniyo kulungelelwaniso olungundoqo lunokuthi lubeke esichengeni isithintelo soxinzelelo kwizindlu zepiston pump cylinder ezilinganiselwe kwi-350 bar. Ezi ayingomngcipheko wethiyori. Zizintsilelo zentsimi esizifumene kwiiyunithi ezintathu zenkonzo ye-oyile yaseMntla Melika-nganye ilandelelwa kulwakhiwo lwenkozo olungangqinelaniyo kwiibhetshi eziphosiweyo.
Yintoni eyahlula umzi-mveliso wesanti yentsimbi ekwaziyo ukugalelwa kumthengisi wentengiselwano? Eyokuqala: udibaniso oluthe nkqo ngaphaya kokuphosa yedwa. Udinga iqabane elisebenza kwindawo enye *emva* kokusakha—kuba kulapho kuphela apho baziva khona iziphumo zoxinzelelo olushiyekileyo, i-carbide banding, okanye ukushwabana okungalinganiyo. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., CNC machining ayisosongezo; linyathelo lokugqibela lokuqinisekisa. Xa begqiba i-T800 cobalt-based winch center shaft roller, baqinisekisa ukujikeleza kwiindawo ezintlanu ze-axial-kungekhona nje kwiqondo lokushisa eliqhelekileyo, kodwa emva kokulinganisa i-120 ° C yokufunxa kokusebenza. Yileyo ndlela ubamba ngayo ukuphazamiseka ngaphambi kokuba ufikelele kumgca wendibano.
Okwesibini: ukulandeleka kwezinto ezihamba nzulu kuneengxelo zovavanyo lokusila. Amanqanaba ensimbi engenastainless njenge-AMS 5387 okanye i-ASTM A743 CA15 ayiziphathanga ngokulinganayo kuwo wonke ubushushu-nokuba luhlobo olufanayo lwegama. Iinguqu ezincinci kumxholo we-nitrogen okanye amanqanaba e-delta ferrite shift machinability, impendulo yokushisa ukushisa, kunye nobomi bokudinwa. I-QINGDAO QIANGSENYUAN igcina intsebenziswano yobugcisa kunye nababoneleli bezinto ezikrwada abaqinisekisiweyo, i-cross-referencing iqashiso ngalinye lobushushu ngokuchasene ne-in-house tensile kunye nedatha ye-Charpy V-notch. Ukuba umthengi ucela i-22% yokwandisa ubuncinci kwi-CF3M yokuphosa, abamkeli nje isatifikethi somboneleli-bayasiqinisekisa kumatshini wabo wokuvavanya, besebenzisa iisampuli ezisikwe kwinkqubo yokukhangela yokwenene yokugalela.
Okwesithathu: ubukhali bokuhlola obubonisa ubukhali bokusetyenziswa kokuphela. Uninzi lwabaseki balinganisa imilinganiselo ebalulekileyo ngee-CMM-kodwa bambalwa abahlola ingqibelelo engaphantsi komhlaba kwiindawo ezingenasihlwathi zesanti. I-QINGDAO QIANGSENYUAN isebenzisa uvavanyo lwe-ultrasonic lwe-array (PAUT) kuwo onke amacandelo aqulethe uxinzelelo olungaphezulu kwe-25 mm, ukuskena izibonakaliso zomgca ezihambelana nolwalathiso lokukhula kwe-dendrite. Kwiindawo ezingacinezeliyo ezifana neziseko zempompo yemoto yobunjineli, zisebenzisa idayi yokuhlola ukungena *emva* kokunciphisa uxinzelelo-kwaye kwakhona emva komatshini wokugqibela-ukubamba ii-microcracks ezivulwe kwakhona. Ingxelo nganye ibandakanya imephu yendawo, hayi nje ukudlula/ukungaphumeleli kwezitampu.
Okwesine: uyilo lokwenziwa ngokutyibilikayo-hayi nje ukutolika kwe-GD&T, kodwa impendulo esebenzayo esekelwe kwifiziksi yokuphosa. Umzekelo: xa umxhasi engenise umzobo ebiza ± 0.05 mm ukunyamezela kwi-flange ye-320 mm ububanzi, iqela labo alizange licaphule okanye ligatye. Balinganise ukucutha kokuqina besebenzisa i-MAGMAsoft, bachonge iindawo ezinokubakhona zemfazwe, kwaye bacebise ukufuduswa kweprinta ezimbini ezingundoqo ukulinganisa ukuthambeka okushushu. Isiphumo? Ukunciphisa ukukhutshwa kwe-post-machining stock ngama-40%, ukuphelisa umsebenzi wokugqiba omnye ngaphandle kokuphazamisa ukucaba. Leyo ayisiyonkonzo-yabelwana ngokunciphisa umngcipheko wobunjineli.
Ewe, ukujulwa kwesanti yentsimbi engenastainless kuthwala ixabiso leyunithi ephezulu kunotyalo-mali lwamaqashiso amancinane-okanye ukuphosa iinxalenye ezingenayo i-ferrous. Kodwa ukuveliswa komthamo ophakathi kwamacandelo afana ne-valve yoxinzelelo lwe-hydraulic (50-500 pcs / ngonyaka), izindlu ze-cylinder ezineziteshi zokupholisa zangaphakathi, okanye iindibano zempompo ezilinganiswe ngaphandle kwe-offshore, ukuchithwa kwesanti kuhambisa ukuguquguquka okungahambelaniyo kubukhulu, ukhetho lwe-alloy, kunye nokwahluka kobukhulu bodonga. Kwaye xa inxalenye yakho kufuneka iphile emanzini olwandle agcwele i-chloride, ukulayishwa kwebhayisikile, kunye neemfuneko zokuvuza kwe-zero, ukuthembeka akuxabiswanga ngekhilogram nganye-kuxatyiswa ngokusilela okuthintelweyo.
Ukuba uvavanya a steel stainless sand casting Foundry factory, buza imibuzo emithathu phambi kokuba usayine i-NDA: Ngaba banokukubonisa ingxelo ye-PAUT yakutshanje ye-CF8M yokuphosa ehambelana nejometri yakho? Ngaba bayayigcina idatha yelog yokunyibilika-kubandakanya ubushushu bokuthulula, uhlalutyo lweladle, kunye nobushushu bokubumba-kwibhetshi nganye ethunyelweyo? Kwaye ngaba bakha bakukhaba okwabo ukuphoswa ngenxa yokuba i-post-machining ibonakalise ukuguquguquka kobunzima obungalindelekanga? Impendulo kuzo zontathu zikuxelela ngaphezu kwaso nasiphi na isatifikethi se-ISO.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka eQingdao-kungekhona njengenkampani yokurhweba ekhupha ngaphandle, kodwa njengomvelisi oqhutywa yiteknoloji apho i-metallurgists iphonononga izigodo zesithando somlilo ecaleni kwenkqubo ye-CNC. Ugxininiso lwabo luhlala lumxinwa: amacandelo amashishini achanekileyo apho umsebenzi uyalela ifom, kwaye apho "ukulunga ngokwaneleyo" kuthetha ukusilela kwentsimi. Olo qeqesho seso sizathu le nto inqanawa yabo yokuphosa isanti engenastainless isiya kwii-OEMs zehydraulic eJamani, abahlanganisi bezixhobo ezingaphantsi kwamanzi eSingapore, kunye nabakhi bezithuthi zemigodi eCanada-hayi ngenxa yokuba bezezona xabiso liphantsi, kodwa ngenxa yokuba bengababoneleli bokugqibela abafowunayo xa iprototype yokuqala ingaphumeleli kuvavanyo lokungcangcazela.
