Xa iinjineli zichaza a steelcasting Foundry factory, abagcini nje ngokuyalela isinyithi-bazibophelela ekuzinzeni kwe-dimensional phantsi kwe-bar ye-300, ukunyaniseka kwe-microstructure emva kokuhamba ngebhayisikili eshushu, kunye nokunyamezela kwe-porosity kwiindawo eziphezulu zokunxiba. Sibone iiprojekthi ezininzi zilibazisekile ngenxa yokuba abathengisi baphatha intsimbi “njengenye ialloyi.” Akunjalo. Iintsimbi eziphantsi kwe-alloy ziqhekeka phantsi kokucima ngokukhawuleza. Amabanga angenaziphene afana neCF8M ayahlula ukuba amazinga okupholisa umngundo akhukuliseka nge ±5°C. Kwaye iindawo zempompo ezisekwe kwi-cobalt-ingakumbi i-AMS 5387 okanye i-T800-zifuna ukuqhubeka kwe-metallurgical kubo bonke ubushushu, hayi nje ukuthobela i-spec sheet.
Kutheni ukulahlwa kwentsimbi kusilela kwangaphambi kokuba umatshini uqalise
Uninzi lweentsilelo lubuyela emva kwizithuba ezithathu ezinokuphepheka: ukufunwa kwemathiriyeli ngaphandle kwesatifikethi somgangatho webhetshi, uyilo lokungunda kwesanti olutyeshela ukuqina kolwalathiso kwizindlu ezishinyeneyo, kunye neeshedyuli zonyango lobushushu eziqhawule umtshato nenxalenye yokwenene yejometri. Kwiziko lethu le-Qingdao, sivavanya iibhiliti ezingenayo ze-316L zomxholo we-ferrite *phambi kokugalela * hayi emva. Senza imephu yemitha ye-thermal kwi-molds yesanti kusetyenziswa i-thermocouples edibeneyo ngexesha lokugalelwa kovavanyo. Kwaye asize sisebenzise umjikelo womsindo ofanayo kwi-45-kg yepiston yendlu yempompo kunye ne-2.3-kg yomzimba wevalve yoxinzelelo. Isayizi enye ayifanelanga nto kwintsimbi echanekileyo yokuphosa.
Yiyo loo nto sidibanisa isicwangciso senkqubo yokuphosa ngokuthe ngqo kuphononongo lwe-GD&T. Xa umthengi ethumela umzobo wendlu yesilinda yensimbi engenastainless ene-± 0.05 mm yokunyamezelana kwesikhundla kwiibhore ezintandathu ezixhomayo, asicaphuli nje ukwenza machining. Siyabuza: Ingena phi isango? Zeziphi iiprinta eziphambili eziya kutshintsha ngexesha le-shakeout? Kungakanani ukuguqulwa kwe-post-cast okwenzeka kwi-650 ° C? Le ayiyomibuzo yethiyori. Zilinganisiwe-kwi-castings yokwenyani, kunye nedatha ye-CMM efakwe kwimigangatho ye-CAD yokuqala.
Udibaniso oluthe nkqo olulawula ukwahluka
Ukukhuphela ngaphandle, emva koko ukwenza ubuchwephesha, emva koko ukugqiba kudala i-handoffs ezintathu-kunye namathuba amathathu empazamo eyongezelekayo. Yethu steelcasting Foundry factory iqhuba utyalo-mali kunye nokuphosa isanti *kwisakhiwo esiqinisekisiweyo se-ISO* apho amaziko e-CNC asebenza khona. Iplagi ye-cobalt-nickel ephoswe kwi-1,420 ° C ihamba ngokuthe ngqo kwi-annealing yokunciphisa uxinzelelo, emva koko iye kwi-axis milling emihlanu-konke kwiiyure ze-48. Akukho zithuthi zihamba phakathi kweziko. Akukho ukulungiswa kwakhona. Akukho zimbekiselo zedatha ezilahlekileyo.
Oku akukho lula-lulawulo oluqhutywa yi-physics. Umahluko wokwandiswa kobushushu phakathi kwesanti yokungunda, intsimbi enyibilikisiweyo, kunye neepleyiti ezifakwe ngoomatshini ziyacuthwa xa onke amanyathelo esenzeka phantsi kophahla olunye kunye nokubekwa esweni kokusingqongileyo. Silandelela ukufuma kwe-ambient kunye nobushushu be-ambient ngeyure-hayi ngenxa yokuba "isenzo esihle," kodwa ngenxa yokuba silinganise indlela i-3% ye-RH swing etshintsha ngayo ixesha lokumisa ukungunda ngokwaneleyo ukuguqula uburhabaxa bomphezulu kubuso obubalulekileyo bokutywinwa.
- Iintsimbi ezenziwe ngoomatshini be-CNC: ≤0.015 mm kwifomu yokutenxa kwi-300 mm ububanzi
- Intsimbi ye-sand-cast carbon (WCB): ukuguquguquka kwamandla okuqina < ± 8 MPa kwii-heats ezili-10 ezilandelelanayo
- Investment-cast stainless (CF3M): Ra ≤1.6 µm as-cast on flow-path surfaces-akukho kusila okwesibini kuyadingeka
- I-AMS 5387 ingxubevange ye-cobalt: ukulandelwa kobushushu obugcweleyo ukuya kubushushu, kubandakanywa nelogi enyibilikayo, uhlalutyo lwespectrographic, kunye nokuqinisekiswa kobungakanani beenkozo nge-ASTM E112
Ukusebenza Kwehlabathi Lokwenyani, Hayi nje Ukuthotyelwa kwePhepha
Abanye ababoneleli ngenqanawa bathumela iintsimbi zentsimbi kunye ne "ISO 9001 eqinisekisiweyo" egxininiswe kuluhlu lokupakisha-kodwa abanako ukuvelisa ingxelo enye yovavanyo eqinisekisiweyo ebonisa iiprofayili zobunzima kwisiseko sempompo ye-120-mm-thick. Siya. Yonke into ethunyelwayo ibandakanya ingxelo yovavanyo lwe-material (MTR) ene-tensile, isivuno, i-elongation, kunye nexabiso lempembelelo-elinganiswa ukusuka kwikhuphoni elisikiweyo *ukusuka kwi-casting efanayo*, kungekhona kwibha yovavanyo eyahlukileyo.
Sikwaqinisekisa ukusebenza okusebenzayo ngaphambi kokuthunyelwa. I-winch center shaft roller ayijongwa nje ububanzi. Ijikeleza nge-1,200 rpm kwi-rig-dynamometer rig yethu ngelixa iigeyiji zoxinzelelo zijonga ukuphambuka kwiindawo ezintathu zeradial. Indlu yevalve yoxinzelelo ayidluli nje uvavanyo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza. Ijikeleza amaxesha angama-5,000 kunye ne-thermal shock-200 ° C ukuya kuma-25 ° C ngaphantsi kwemizuzwana engama-90 - emva koko ihlolwe ngedayi. Ukuba iyaqhekeka, siyila ngokutsha inkqubo yokunyuka-hayi inkqubo ye-NDT.
Yintoni omawuyifune kwiqabane lakho lokuphosa intsimbi
Sukuvuma ukuba "siphosa intsimbi." Buza endaweni yoko:
- Ngaba ungandibonisa iilog zobushushu ezintathu zokugqibela zobonelelo lwakho lwe-ASTM A216 yeBanga le-WCB-kwaye uqinisekise ukuba zonke zithathwe kumatshini omnye wokusila?
- Ngaba ulinganisa ukuqina kwi-MAGMAsoft okanye okufanayo ngaphambi kokuba uvume uyilo lokubumba?
- Ngaba uhlolo lwakho lokugqibela lwenziwa kwi-CMM elungelelanisiweyo-okanye ngee-micrometers eziphathwa ngesandla kunye nokuhamba / akukho-hamba igaraji?
- Xa ukuphosa kusilela kuhlolo olubonakalayo, ngaba uyalukrazula-okanye wenze uhlalutyo lwengcambu kuhlobo lokufakwa, ukuhanjiswa kwerhasi porosity, kunye ne-dendrite arm spacing?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iimpendulo ewe kuzo zone. Akunjalo njengamabango okuthengisa-kodwa njengamanyathelo okuhamba komsebenzi abhaliweyo, abonakala kwiirekhodi zethu zemveliso kunye nokuqinisekiswa ngexesha lokuphicothwa kwabathengi. Sakha iintsimbi zentsimbi kwiinkqubo ze-hydraulic eziqhuba iiyure ze-18,000 ngaphandle kokutshintshwa kwetywina. Kwiimpompo ze-oilfield ezibamba i-H₂S-laden fluid kwi-120 °C. Kwii-winch zemoto zobunjineli eziphakamisa imithwalo ye-8.5-toni kwiimeko ezingaphantsi kwe-zero. Ukuthembeka akuyiyo into ekujoliswe kuyo. Kuyimveliso yeenkqubo ezilawulwayo-zilinganisiwe, ziphindwe, ziqinisekisiwe.
Ukuba i-odolo yakho yokuphosa yentsimbi elandelayo ifuna okungaphezulu kokuthotyelwa kwe-dimensional-ukuba ifuna ukuqikelelwa kolwakhiwo, ukuhambelana kwe-metallurgical, kunye nokuqinisekiswa kokusebenza-qala ngokubonakala kwenkqubo. Hayi iincwadana. Ayizozatifikethi zodwa. Kodwa ukufikelela ngexesha lokwenyani lokuphosa izingodo, iitshathi zokunyanga ukushisa, kunye neengxelo zeCMM. Yiloo ndlela a steelcasting Foundry factory ifumana indawo yayo kuthungelwano lonikezelo olubalulekileyo.
