Wese injinjiniya anoziva izvi: kukanda kubudirira kunotanga nguva refu isati yadururwa. Zvinotanga nekurudyi simbi yekukanda zvinhu-kwete zvigadziriso chete, asi zvimisikidzo, mabhandi, machira ekuumbwa, majecha epakati, uye zvinhu zvegedhi zvinodzora kuyerera kwekupisa, kupera kwepamusoro, uye kudzokorora kwedimensional. Takaona kukanda kwakawanda kwe-high-value kukundikana-kwete kubva mukugadzirwa kwakashata kana sarudzo yealloy, asi kubva mukusawirirana kwejecha kugoverwa kwezviyo, kemisitiri yechinyakare yebhainda, kana jira rinoputika pasi pekupisa kwekushisa. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kwatinogadzira AMS 5387 cobalt alloy pombi housings uye T800-based nozzles ye hydraulic systems inoshanda pa420 bar, kuvimbika hakusi chido. Yakagadzirirwa mune yega yega sarudzo yekugovera.
Refractory Materials Inomira Chaiyo-World Thermal Stress
Haasi ese marefractories anoita zvakafanana pasi pekudzokororwa kupisa bhasikoro. Silica jecha rinoshandira simbi yakaderera-alloy — asi inokundikana zvakanyanya necobalt-nickel alloys pamusoro pe1,400°C. Mune yedu ISO-inoenderana nekuwana, isu tinoshandisa yakasanganiswa alumina uye zircon musanganiswa wekudyara magomba magomba achikanda AMS 5387 zvikamu. Sei? Nekuti zircon's coefficient yekuwedzera kwekupisa inoenderana necobalt alloys padhuze-kuderedza kuputika kwegoko panguva yekudonha uye preheat. Silica-based coatings blister pasi pekukurumidza kupisa; zircon-based vanobata kuvimbika. Isu tinoyedza batch yega yega kugovera saizi (D50 ≤ 45 µm) uye hunyoro hwemukati (<0.3%) isati yanyura goko. Mumwe mutengi akachinja vatengesi asina kugadzirisa preheat ramp rates-uye akaona 22% shell spalling mumabhechi ekutanga. Kugadzirisa kwanga kusiri midziyo mitsva. Kwaifananidzira hunhu hwekuramba kune yavo chaiyo profile profile.
Binders uye Core Systems Inoendesa Dimensional Kugadzikana
Core shift inoparadza piston pombi silinda dzimba. Kutsauka kwe 0.15 mm munzvimbo yemukati yemukati zvinoreva kutadza kushanda. Isu tinoshandisa inotonhora-bhokisi phenolic urethane binders-kwete yemutengo, asi yegirinhi simba rekuchengetedza pa 35-40% hunyoro hwehukama uye kugadzikana kwekuita shakeout. Yedu data inoratidza macores akagadzirwa nemabhainda aya anobata ± 0.08 mm positional kushivirira pamazana mashanu-mayuniti ekugadzira anomhanya. Zvimwe zvitoro zvichiri kuvimba nefuran-no-bake system, asi sarufa yavo yakasara inosimudzira micro-porosity musimbi isina tsvina. Pakukanda simbi kunoda Class 30+ tensile simba, tinotsanangura alkaline phenolic binders-low-salfur, high-ash-simba, uye inopindirana ne automated core shooting line. Kiyi haisi yebhinder type chete. Ndiwo mashandisiro anoita binder cure kinetics kuenderana neyako yepakati bhokisi tembiricha, ambient humidity, uye dhizaini nguva.
Mold Coatings uye Anoburitsa Agents Anodzora Surface Kutendeseka
Nzvimbo yekukanda haisi yekushongedza-inoshanda. Pombi nheyo dzinoda Ra ≤ 3.2 µm yekuvhara gasket; winch centre shaft rollers inoda nzvimbo dzisina kukanganisa kudzivirira kupera nguva isati yakwana. Isu tinoisa aqueous ethyl silicate-bonded zircon coatings kuburikidza ne airless spray-viscosity inodzorwa pa22-24 sec (Ford Cup #4), solids content pa68-70%. Kuonda zvakanyanya? Kusagadzikana kwekukurwa kwevhu. Zvakanyanya kukora? Kupwanya uye kabhoni pickup. Isu tinosimbisa ukobvu hwekuvhara ne eddy-yazvino geji-chinangwa: 0.25-0.35 mm yakaoma firimu. Kune zvisiri-standard T800 alloy components, tinowedzera 3-5% colloidal graphite kuti tivandudze kuyerera kwesimbi muzvikamu zvitete. Hapana off-the-sherufu "universal" coating inopa izvo. Iko kuumbwa, nzira yekushandisa, uye nguva yekuoma-yakaedzwa pamwe chete, kwete yekuzviparadzanisa.
Traceability-Yakagadzirira Zvishandiso zveMishoni-Yakakosha Castings
Kana vharuvhu yekumanikidza ikatadza munzvimbo yemafuta akawanda, kuteedzera hakusi mapepa-kuderedza mutoro. Yese dhiramu rejecha rezircon, pega rega rebhainda, bhechi rega rega rekuputira slurry rinopinda munzvimbo yedu rinotakura nhamba yakawanda, mutengesi chitupa chekuongorora, uye metallurgical test report. Isu tinochengeta kuteedzera kuzere kubva kune yakasvibirira risiti kuburikidza nekupedzisira CMM yekuongorora-kudzika kusvika kunhamba yekupisa yega yega cobalt alloy ingot inoshandiswa muAMS 5387 zvikamu. Izvi zvinoreva kuti kana mutengi akataura porosity na12 o'clock pahumburumbira, tinogona kupatsanura iyo jecha chaiyo, binder batch, uye coating dip cycle-uye kubereka mamiriro acho mukudururwa. Vazhinji vatengesi vanotumira zvinhu zvakasimbiswa. Vashoma vanobatanidza chitupa mune chaiyo-nguva process process control. Isu tinoita-nekuti kurongeka kwedimensional uye kuvimbika kwechimiro hazviwanikwe muchoto chekunyungudika chete. Vakavharirwa mukati padanho rekupa.
Yakavimbika foundry mhedzisiro haibvi kune chimwe chinhu chakakwana. Ivo vanobuda kubva mumaune, yakaedzwa sarudzo yega yega simbi yekukanda zvinhu chinhu chiri mukufamba kwako-kubva pakukura kwezviyo zvezviyo kusvika kubhainda rehupenyu hwesherufu kusvika pakuputira viscosity. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Isu tinobata zvekukandira zvekushandisa kwete sezvinobatika, asi sezvikwanisiro zvinogonesa. Mafungiro iwayo anoparadzanisa kuita kunodzokororwa kubva kunodhura rework. Sezvo mahybrid ekukanda-machining maitiro anokura akajairika-kunyanya kune yakakwirira-alloy pombi uye mavharuvhu masisitimu - muganho wekupa-cheni musiyano unodzikira. Sarudza vatengesi vanoyera, simbisa, uye gwaro - kwete kungoendesa.
