Ububanzi obukhulu beC93200 Lead Tin Bronze Tube – Bearing Grade Alloy

Ibha yeBronze yeTin enkulu (Φ120mm nangaphezulu) – Isongezelelo soBugcisa

Siziingcali ekuveliseni iibhari zobhedu ezinkulu ezinobubanzi obuqala kwi-Φ120mm ukuya kwi-Φ650mm. Amanqanaba aphambili aquka i-C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, njl. Izinto zinganikezelwa kwi-GB/T 13808, ASTM B505, JIS H3270, EN 1982, okanye ikhemistri kunye neepropati ezenziwe ngokwezifiso ngokupheleleyo ngokweemfuno zomthengi.

Inkqubo yoMveliso ephambili

● Ukuphoswa okuqhubekekayo okulandelwa kukukhupha amanzi ombane okunzima (ubunzima bebha enye ziitoni ezi-3–8) kuqinisekisa ulwakhiwo oluxineneyo ngokupheleleyo ngaphandle kokuncipha kwe-porosity kwiidayamitha ezinkulu.
● Ukusebenza ngobushushu/ngokubandayo okuhamba ngeendlela ezininzi kunye nokutsalwa kwe-intermediate okulawulwa ngokuchanekileyo kususa isakhiwo se-dendritic, nto leyo ephumela kwi-α+(α+δ) eutectoid matrix ehambelanayo enobukhulu obuqhelekileyo be-grain 0.025–0.050 mm.
● Ibha yonke ayinamthungo kwaye ayinamakhonkco kuyo yonke ubude bayo.

Iimbalasane zoLawulo loMgangatho

● Ukwakhiwa kweekhemikhali: Uhlalutyo lwe-spectrometer yokufunda ngqo (SPECTRO) olwenziwa kubushushu ngabunye; zonke izinto ezilandelelanayo (P, Fe, Sb, Bi, njl.njl.) zilawulwa ukuya kwi-50% yemida eqhelekileyo okanye eqinileyo.
● Iimpawu zoomatshini: Amaxabiso aqhelekileyo kwiibha ze-Φ≥200mm: Amandla okutsalwa ≥450 MPa, amandla okuvelisa ayi-0.2% ≥200 MPa, ukunwebeka ≥15%, ubulukhuni HB120–180 (kuqinisekisiwe ngokupheleleyo).
● Ukuqina kwangaphakathi: Uvavanyo lwe-ultrasonic oluyi-100% ngokwenqanaba le-ASTM B594 Class A okanye le-SEP 1921 E/e kusetyenziswa ii-probes ze-6–10 MHz. Iingxelo ze-UT ezipheleleyo kunye neefoto ze-macro/microstructure ziyafumaneka ngokwebha nganye xa iceliwe.
● Ukunyamezelana kobukhulu: Ukunyamezelana kobubanzi ± 0.5 ukuya ku ± 1.5 mm (kungcono kune H11), ukuthe tye ≤1 mm/m, ukunyamezelana kobude obunqunyiweyo ± 20 mm.
● Ukugqitywa komphezulu: Ukuchaneka okujikiweyo emva kokukhupha, uburhabaxa bomphezulu iRa ≤3.2 μm, ayinazimfanta, izinto ezifakwe ngaphakathi, okanye iziphene zexolo le-orenji.

Iingxelo zeZibonelelo

● Iipropeller ezinkulu zaselwandle (iibha zeCuSn10Zn2 ezineetoni ezi-3–5)
● Izixhobo zokunxibelelana ze-circuit breaker ezine-voltage ephezulu (CuSn6/CuSn8)
● Iinkqubo zemibhobho yamanzi olwandle (C51900 ububanzi obukhulu)
● I-bronze ye-tin-phosphorus enamandla aphezulu yokusetyenziswa koololiwe kunye namandla omoya

Ixesha lokufumana izinto: Iintsuku ezingama-30–45 kwizinto eziqhelekileyo, iintsuku ezingama-20 ezinokwenzeka kwiiodolo ezingxamisekileyo ngokusebenzisa ishedyuli ekhethekileyo. Inkqubo yefektri kunye nokuhlolwa komgangatho kuyamkeleka rhoqo.
