I-Bronze Tube Enkulu Ene-Leaded Tin C93200 – I-Bearing Grade Alloy

Ibha Yethusi Enkulu Yethini (Φ120mm nangaphezulu) – Isengezo Sobuchwepheshe

Singochwepheshe ekukhiqizweni kwezingodo zethusi ezinkulu ezisukela ku-Φ120mm kuya ku-Φ650mm. Amabanga ayinhloko afaka phakathi i-C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, njll. Izinto zinganikezwa ku-GB/T 13808, ASTM B505, JIS H3270, EN 1982, noma ikhemistri kanye nezakhiwo ezenziwe ngokwezifiso ngokugcwele ngokwezidingo zamakhasimende.

Inqubo Eyinhloko Yokukhiqiza

● Ukuphonswa okungapheli okulandelwa yi-hydraulic extrusion enzima (isisindo sebha eyodwa esingamathani angu-3–8) kuqinisekisa isakhiwo esiqinile ngokuphelele ngaphandle kokuncipha kwama-porosity kuma-diameter amakhulu.
● Ukusebenza okushisayo/okubandayo okudlula izikhathi eziningi kuhlanganiswe nokunamathela okuphakathi okulawulwa kahle kuqeda isakhiwo se-dendritic, okuholela ku-α+(α+δ) eutectoid matrix efanayo enosayizi ojwayelekile wezinhlamvu ongu-0.025–0.050 mm.
● Ibha yonke ayinamthungo futhi ayinamajoyinti kuyo yonke ubude bayo.

Okuvelele Kokulawula Ikhwalithi

● Ukwakheka kwamakhemikhali: Ukuhlaziywa kwe-spectrometer yokufunda ngqo (SPECTRO) okwenziwa ekushiseni ngakunye; zonke izakhi zokulandelela (P, Fe, Sb, Bi, njll.) zilawulwa ku-50% wemikhawulo ejwayelekile noma eqinile.
● Izakhiwo zemishini: Amanani ajwayelekile emigoqweni engu-Φ≥200mm: Amandla okunamathela ≥450 MPa, amandla okukhiqiza angu-0.2% ≥200 MPa, ukunwebeka ≥15%, ubulukhuni HB120–180 (kuqinisekisiwe ngokugcwele).
● Ukuqina kwangaphakathi: Ukuhlolwa kwe-ultrasonic okungu-100% ngokwezinga le-ASTM B594 Class A noma le-SEP 1921 E/e kusetshenziswa ama-probe angu-6–10 MHz. Imibiko ephelele ye-UT kanye nezithombe ze-macro/microstructure ziyatholakala ngebha ngayinye uma uceliwe.
● Ukubekezelelana kobukhulu: Ukubekezelelana kobubanzi ± 0.5 kuya ku-± 1.5 mm (kungcono kune-H11), ukuqondeka ≤1 mm/m, ukubekezelelana kobude obunqunyiwe ± 20 mm.
● Ukuphela kobuso: Ukulungiswa okunembile ngemva kokukhishwa, ubulukhuni bobuso I-Ra ≤3.2 μm, ayinayo imifantu, ukunamathela, noma amaphutha esikhumba esi-orange.

Izinkomba Zokunikezwa

● Ama-propeller amakhulu asemanzini (amabha e-CuSn10Zn2 angamathani angu-3–5)
● Oxhumana nabo be-circuit breaker abane-voltage ephezulu (CuSn6/CuSn8)
● Izinhlelo zamapayipi amanzi olwandle (ububanzi obukhulu be-C51900)
● Ithusi le-tin-phosphorus elinamandla aphezulu lokusetshenziswa kwezokuthutha ngesitimela kanye namandla omoya

Isikhathi sokulethwa: Izinsuku ezingu-30–45 zezinto ezijwayelekile, izinsuku ezingu-20 ezingenzeka kuma-oda aphuthumayo ngokuhlela okuzinikele. Inqubo yasefektri kanye nokuhlolwa kwekhwalithi kuyamukeleka njalo.
