AISI 8620 investimendi yekukandira fekitori haingori mutsara-iye bhenji rekuita. Kana chitima chako chegiya chichifanira kurarama 150,000 cycles pasi pe 350 MPa hydraulic load, kana motokari yako yekufambisa motokari inobvumira kudzokororwa kwekushisa kwekushisa kubva -40 ° C kusvika + 180 ° C, sarudzo yezvinhu uye maitiro ekugadzirisa mira kuva sarudzo. Vanova vasina-negotiable. AISI 8620 simbi inoburitsa yakaringana: kuomarara kwakadzika kubva nickel-chromium-molybdenum alloying, yakanaka-grained microstructure mushure mekuviga carburizing, uye kwakasiyana-siyana kuoma kwepakati-* kana* maitiro ekukanda akachengetedza kuvimbika kwayo kwesimbi. Ndiko uko vatengesi vazhinji vanokundikana-kwete pakupisa kupisa, asi pakutanga: mukugadzira mold, kugadzikana kwegoko, uye kusimba kwekudzora.
Nei AISI 8620 Inoda Investment Casting-Kwete Jecha kana Kufa
Kukandwa kwejecha kunoita kuti zviyo zviome pedyo nemadziro ekuumba; kufa kukanda hakugone kubata AISI 8620's high melting point (1490 ° C) kana kunzwisiswa kwayo nekukurumidza kutonhora kutsemuka. Investment casting inogadzirisa zvese. Goko rayo receramic rinobvumira kunonoka, kwakananga kusimba-yakakosha kuti uwane yunifomu yekesi kudzika panguva inotevera carburizing. Isu takayera kusvika 22% kuvandudzwa mune kesi-yepakati shanduko zone kuomarara gradient kuenderana maringe nejecha-kukanda akaenzana pamagiya akafanana. Zvakanyanya kusimba: mutakuri wepuraneti watakapa kune Tier-1 EV drivetrain mutengi yakaratidza 0.08 mm dimensional kudhiraivha mushure memaawa mazana mashanu ekukasira kuyedzwa kwekupfeka-ichipikisa 0.21 mm mune inokwikwidza jecha-cast unit. Musiyano waive usiri machining. Yakanga iri as-cast microstructure.
Zvina Zvisina Kukurukurirana muAISI 8620 Investment Casting Factory
Havasi vese vanowana vanobata AISI 8620 nekuoma kwakaenzana. Hezvino izvo zvinoparadzanisa mishoni-yakakosha kugona kubva kune commodity inobuda:
- Raw material traceability pasi kusvika pakupisa nhamba- hapana kusanganiswa kwebatch. Yese AISI 8620 ingot inosimbiswa kune ASTM A304, ine yakazara spectrographic mishumo yeNi (0.4–0.7%), Cr (0.4–0.6%), uye Mo (0.15–0.25%) zvirimo. Kutsauka kunze ± 0.03% kunokonzeresa kugadzikwa kwega.
- Shell drying protocols dzakagadziriswa kusvika kune dova, kwete nguva. Humidity inopfuura 45% RH panguva yekudonha inokonzeresa micro-porosity mu5-12 µm renji-isingaonekwe neX-ray asi njodzi pasi pekuneta kurodha. Yedu kilns inopinda chaiyo-nguva RH uye tembiricha yega 90 masekondi.
- Pre-carburizing stress relief pa650°C kwe4 hours—kwete zvokusarudza. Kusagadzikana kwekukanda kudzvinyirira kunokanganisa magiya panguva yekuomeswa kwekesi. Isu tinosimbisa kusara kwekushushikana kuburikidza negomba-kuchera dhizaini gauging pane yekutanga-chinyorwa samples.
- CMM-based as-cast inspection pamberi pechero machining. Isu tinotarisa gumi nemaviri akakosha GD&T callouts-kusanganisira chimiro chepamusoro pane giya mazino mativi uye chinzvimbo kushivirira kwehukama-kune-chiso hukama-padanho regirinhi. Kana ikatadza pano, hapana huwandu hwekugadziriswa kweCNC hunochengetedza chikamu.
Iko Mafekitari Akajairwa Anocheka Makona-uye Isu Hatiite
Mamwe mafekitori eAISI 8620 ekudyara ekudyara anosvetuka pre-alloy vacuum degassing, achifunga kuti chiyero cheEAF chekunyungudutsa chinokwana. Asi okisijeni yemukati iri pamusoro pe20 ppm inogadzira ma oxide stringers anotanga kupinza mazino egiya. Isu tinoshandisa VIM + ESR kunatsa kune ese aerospace uye mota mirairo-kuderedza O₂ kusvika. <8 ppm uye sarufa kusvika <0.002%. Imwe nzira yekudimbudzira yakajairwa: kushandisa generic shell coatings pane zircon-based slurries yakagadziridzwa kune yakakwirira-alloy simbi. Generic coatings inoputika pa1400 ° C, ichiunza refractory inclusions. Yedu slurry magadzirirwo anosanganisira 12% yakasanganiswa silica binder uye particle-size kugovera kunosimbiswa nelaser diffraction-batch yega yega.
Vatengi vanowanzobvunza kuti: "Unokwanisa here kubata ± 0.025 mm pane 120 mm pitch denderedzwa dhayamita?" Ehe-asi chete kana iyo giya blank's as-cast madziro ukobvu musiyano ukaramba uri mukati me ± 0.3 mm. Ndosaka mainjiniya edu ekushandisa achimhanyisa simulation yekusimbisa (vachishandisa MAGMASOFT®) * isati * yabvumidzwa. Isu tinomepu zvinopisa zvinopisa pamuti wese wekukanda, tozogadzirisa gating kubvisa nzvimbo dzinopisa. Chikamu chapfuura, izvi zvakadzivirira magiya makumi matatu nemanomwe pane imwe odha yegungano re hybrid axle.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.: Precision Forged in process Discipline
Kubva kuQingdao, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshandisa ISO 9001-yakasimbiswa nzvimbo uko AISI 8620 yekukandira mari isiri yega-yakabatanidzwa. CNC machining inoitika pane imwechete pasi, ine yakagovaniswa CMM data loops. Kana giya rakashama rasvika kubva pakukanda, iyo chaiyo geometry inodyisa yakananga muCNC chirongwa cheturusi nzira muripo-hapana bhuku rekushandisa rekupinda. Marongero ekurapa kwekupisa akabatana nekukanda manhamba muMES yedu, saka carburizing paramita otomatiki gadzirisa zvichienderana nekuomarara kwekutanga bvunzo kubva mukupisa chaiko.
Hatitengesi zvikamu. Isu tinopa kugadzirira kushanda. Izvi zvinoreva kusimbisa giya mesh mapatani ane optical profilometry isati yatumirwa. Zvinoreva kupa zvizere macert ezvinyorwa, marekodhi kuvaka marekodhi, uye post-kupisa-kurapa mamicrographs pakukumbira. Zvinoreva kubata stock yeAISI 8620 master alloys kubva kune vatatu vane certified vatengesi-saka kukanganiswa kweketani yekugovera hakumbononoke prototype yako.
Iyo AISI 8620 yekudyara yekudyara fekitori inowana kuvimba kwete kuburikidza nemabhurocha, asi kuburikidza nekudzokorodza: yakafanana kuomarara chimiro muzvikamu mazana mashanu, hupenyu hwekuneta hwakafanana mumakore matatu ekugadzira, kugadzikana kwedimensional kugadzikana mushure me10,000 yekudziya kutenderera. Ndiyo yakajairwa QINGDAO QIANGSENYUAN TECHNOLOGY inosangana-kwete pano neapo, asi zvakarongeka. Nekuti mune chaiyo giya uye mota application, "pedyo zvakakwana" haipo. Ndizvo chete zvinoita.
