Chitoliro Chachikulu Cha C93200 Chopangidwa ndi Tin Bronze - Bearing Grade Alloy

Chitsulo Chachikulu Chamkuwa Cha Tin (Φ120mm ndi kupitirira apo) - Chowonjezera Chaukadaulo

Timapanga zinthu zachitsulo zazikulu kuyambira Φ120mm mpaka Φ650mm. Zinthu zazikulu ndi monga C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, ndi zina zotero. Zinthuzo zitha kuperekedwa ku GB/T 13808, ASTM B505, JIS H3270, EN 1982, kapena mankhwala ndi zinthu zomwe zasinthidwa malinga ndi zomwe kasitomala akufuna.

Njira Yopangira Zinthu Yofunika Kwambiri

● Kuponya kosalekeza kotsatiridwa ndi kutulutsa kwamadzimadzi kolemera (kulemera kwa bar imodzi matani 3–8) kumatsimikizira kapangidwe kolimba mokwanira popanda kufooka kwa ma porosity m'ma diameter akuluakulu.
● Kugwira ntchito yotentha/yozizira kwambiri pamodzi ndi kupopera kwapakati kolamulidwa bwino kumachotsa kapangidwe ka dendritic, zomwe zimapangitsa kuti α+(α+δ) eutectoid matrix ikhale yofanana ndi kukula kwa tinthu tating'onoting'ono ta 0.025–0.050 mm.
● Bala lonse ndi lopanda msoko komanso lopanda ma connection kutalika kwake konse.

Mfundo Zazikulu Zokhudza Kulamulira Ubwino

● Kapangidwe ka mankhwala: Kusanthula kwa spectrometer yowerengera mwachindunji (SPECTRO) komwe kumachitika pa kutentha kulikonse; zinthu zonse zotsalira (P, Fe, Sb, Bi, ndi zina zotero) zimayendetsedwa mpaka 50% ya malire wamba kapena okhwima.
● Kapangidwe ka makina: Mtengo wamba wa mipiringidzo ya Φ≥200mm: Mphamvu yolimba ≥450 MPa, mphamvu yokolola ya 0.2% ≥200 MPa, kutalika ≥15%, kuuma HB120–180 (kotsimikizika mokwanira).
● Kulimba kwa mkati: Kuyesa kwa 100% kwa ultrasound pamlingo wa ASTM B594 Class A kapena SEP 1921 E/e pogwiritsa ntchito ma probe a 6–10 MHz. Malipoti athunthu a UT ndi zithunzi za macro/microstructure zimapezeka pa bala lililonse mukapempha.
● Kulekerera kwa miyeso: Kulekerera kwa m'mimba mwake ± 0.5 mpaka ± 1.5 mm (kwabwino kuposa H11), kulunjika ≤1 mm/m, kulekerera kutalika kwa kudula ± 20 mm.
● Kumaliza pamwamba: Kutembenuka bwino kwambiri pambuyo potulutsa, kuuma kwa pamwamba Ra ≤3.2 μm, kopanda ming'alu, zosakaniza, kapena zolakwika za khungu la lalanje.

Zolemba Zopereka

● Ma propeller akuluakulu a m'madzi (mipiringidzo ya CuSn10Zn2 imodzi ya matani 3–5)
● Ma contact a circuit breaker amphamvu kwambiri (CuSn6/CuSn8)
● Mapaipi amadzi a m'nyanja (C51900 lalikulu m'mimba mwake)
● Mkuwa wamphamvu kwambiri wa tin-phosphor wogwiritsidwa ntchito poyendetsa sitima ndi mphamvu ya mphepo

Nthawi yoperekera zinthu: Masiku 30–45 pazinthu wamba, masiku 20 otheka kuti muyitanitse mwachangu kudzera mu ndondomeko yapadera. Njira zoyendetsera mafakitale ndi kuwunika kwabwino ndizolandiridwa nthawi zonse.
