Gray iron castings inopa kusimba kusingaenzaniswi uye mutengo unoshanda weyakanyanya-kushushikana maindasitiri zvikamu-kunyanya uko kudonhedza kunoderedza, kupfeka kuramba, uye kugadzikana kwemafuta zvakanyanya. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takagadzira pamusoro pe12,000 grey iron casting units for hydraulic valve body, pombi housings, uye engineering mota yemabhureki madhiramu kubvira 2020. Chikamu chega chega chinosangana neASTM A48 Kirasi 30B shoma yekusimba simba (207 TMiteled control AS morphology) A247-nekuti kusawirirana kweflake kunokonzera kuneta nguva isati yakwana kutsemuka mumacylinder liner pasi pekumanikidzwa kwecyclic.
Nei Grey Iron Ichiri Kuhwina Painoverengera
Vamwe mainjiniya vanofungidzira ductile simbi kana simbi inofanirwa kutsiva grey simbi mune inoda maapplication. Asi chaiyo-yenyika data inotaura imwe nyaya. Muchidzidzo chenguva pfupi yapfuura che475 piston pombi silinda dzimba kumativi ese eNorth America mafuta ebasa rezvikepe, shanduro dzegrey iron dzakatora nguva yakareba 18% kupfuura yakaenzana ductile iron units pasi pemitoro 3,000-psi pulsating. Sei? Ma graphite flakes anoshanda semadziva akavakirwa mukati memafuta ekuzora mukati memuganhu wemafuta-uye anotora simba rekudengenyeka iro ringadai richipararira mumabhuraketi uye zvidhindo zvinosungirirwa.
Tinoona izvi zuva nezuva mumutsara wedu wejecha: apo vatengi vanochinja kubva kune ductile iron kuenda kuASTM A159 G3000 grey iron yewinch centre shaft rollers, machining nguva inodonha 22% nekuda kwekuoma kwakadzika (187-229 HBW vs. 241-269 HBW) uye yepamusoro-soro chip-breaking maitiro. Izvo hazvisi zvekufungidzira-inoyerwa pane yedu Okuma MULTUS U3000 akawanda-axis CNCs panguva yekupedzisa kutendeuka mashandiro. Hapana nzara inotonhorera. Hapana kutaurirana kwemidziyo. Kungofanana kwepamusoro kunopera paRa 1.6 µm.
Grey iron inogadzirisawo matambudziko ekutonga kwekupisa zvimwe zvinhu hazvigone. Pombi nheyo dzakafumurwa kune dzimwe nguva kupisa kwemvura inopisa (semuenzaniso, 60 ° C kusvika 120 ° C mumasekondi makumi mapfumbamwe) inoratidza 40% kushomeka kwekupisa kwegireyi simbi maringe nesimbi isina 316 castings. Chikonzero chacho? Higher thermal conductivity (50 W/m·K vs. 16 W/m·K) uye yakaderera coefficient of thermal kuwedzera (10.4 × 10⁻⁶/°C vs. 16 × 10⁻⁶/°C). Isu tinosimbisa izvi tichishandisa infrared thermography panguva yekuyedzwa kwekushanda-pasina kufungidzira.
Mutengo Wakavanzika we "Kuchipa" Grey Iron Castings
Haisi yese grey iron inoita zvakafanana. Takaongorora makumi matatu nemumwe evashambadziri eASTM A48 Kirasi 25 grey iron pressure valve miviri - uye takawana 68% yakundikana basic metallurgical cheki. Nyaya dzakajairika dzinosanganisira yakawandisa phosphorus (> 0.12%), isingadzorerwe pearlite yemukati (<80% munzvimbo dzinotakura mutoro), uye yakasara magnesium carryover kubva kumberi ductile iron inodurura. Izvi zvinokanganisa zvinokonzeresa kuputsika pakutonhora kwekutanga kana kudhiraivha kwemukati mushure mekupisa bhasikoro.
PaQINGDAO QIANGSENYUAN, simbi yega yega inonyunguduka inotanga nesimbi yenguruve yakaderera-phosphorus (≤0.05% P) uye zvinonatsa zviyo zveferrosilicon. Isu tinobata kabhoni yakaenzana (CE) pakati pe 3.7-4.1 kuenzanisa fluidity uye simba - tisingambodzingirira nhamba dzakanyanya kusimba nekurasikirwa kwemachinability. Yedu matanda evira anoteedzera sarufa, manganese, uye kutonhora mitengo munguva chaiyo. Kana CE ikadonha kupfuura ± 0.05, tinorasa kupisa-kwete kudzikisira.
Kurangwa ikoko kunobhadhara. Vatengi vanoshuma zero kutadza kwemunda pane yedu AMS 5387-inoenderana grey iron pombi zvikamu pamusoro pemwedzi makumi mana nemaviri yekuenderera mberi kwekushanda mumapuratifomu ekuSoutheast Asia. Corrosion kuramba haisi yega-asi yedu inodzorwa microstructure inoramba sulfide stress kupaza zvirinani pane generic foundry mamakisi.
Nguva Yekusarudza Grey Iron Pamusoro pedzimwe nzira
Sarudza grey iron castings kana application yako ichida:
- Vibration damping - Yakakosha kune compressor mabhesi, giya rekudzikisira dzimba, uye bvunzo rig mafuremu
- Kuzvizora zvifukidzo zvinopfeka - Yakanakira madhiramu emabhureki, mahwendefa eclutch, uye nzira dzekutsvedza
- Dimensional kugadzikana pasi pekupisa bhasikoro - inopupurirwa mumabhuroki einjini, manifolds ekuburitsa, uye kupisa exchanger cores
- Kugadzirwa-kusingadhuri kwepakati-vhoriyamu - grey iron yekushandisa mari inomhanya 30-50% pazasi pekudyara kukanda kune zvikamu> 5 kg
Dzivisa simbi yegrey chete kana kuoma kwekupedzisira kuchidikanwa (semuenzaniso, mazino emubhaketi wekuchera) kana kana kuratidzwa kuchipfuura 500°C nguva dzose. Kune zvimwe zvese-kusanganisira mavharuvhu akaiswa ku10,000 psi, piston pombi silinda dzimba dzine 0.025 mm kushivirira, uye mainjiniya emota winch rollers inobata 80-ton static mitoro - grey iron inoramba iri sarudzo yakagadzirwa.
Kudyidzana Kwechokwadi Kunotanga Nehungwaru Hwezvinhu
Kusarudza grey iron castings haifaniri kureva kusarudza pakati pemutengo nekuita. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata kusarudzwa kwezvinhu sehuinjiniya hwekushandira-kwete kutenga. Chikwata chedu chinoongorora kusheedzera kweGD&T chisati chataura, chinoisa mireza njodzi dzinogona kudonha muzvikamu zvitete-madziro, uye inosimbisa mold kuyerera inopesana nemiedzo chaiyo yekudira. Isu hatingotumire majekiseni - tinoendesa akasimbiswa mamicrostructures, akanyorwa kuteedzera pasi kusvika kunhamba yekupisa, uye mishumo yakasainwa neCMM-yakasimbiswa inspector.
Kune vatengi vanotsanangudza grey iron castings, isu tinokurudzira kutanga nemibvunzo mitatu: Ndeipi yakanyanya kutadza maitiro mudhizaini yako yazvino? Ndedzipi nzvimbo dzinotakura mutoro zvichienzaniswa nedzinoda kuiswa chisimbiso? Uye madhigirii ekupisa anozogovanisa sei mhiri kwechikamu panguva yekushanda? Pindura izvo-uye isu tinokufananidza negiredhi rakakodzera, nzira yekugadzirisa, uye yekuongorora protocol.
Gray iron castings haisi tekinoroji yenhaka. Iwo akanyatso-engineered mhinduro dzakanatswa pamusoro pemakore 150-uye dzichiri kubuda. Pane yedu ISO-inoenderana nzvimbo muQingdao, kudururwa kwega kwega kunofambira mberi. Nekuti kusimba hakusi kwesimba chete. Ndezvekufanotaura. Consistency. Kudzora.
