Dhayamita Yakakura C93200 Tin Bronze Tube - Bearing Grade Alloy

Bhawa reBronze reTin rakakura (Φ120mm zvichikwira) - Chiwedzerwa cheTechnical

Isu tine hunyanzvi mukugadzira simbi dzebronze dzine dhayamita yakakura kubva kuΦ120mm kusvika kuΦ650mm. Magiredhi makuru anosanganisira C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, nezvimwewo. Zvinhu zvinogona kupihwa kuGB/T 13808, ASTM B505, JIS H3270, EN 1982, kana makemikari nezvivakwa zvakagadzirwa zvizere zvichienderana nezvinodiwa nevatengi.

Maitiro Akakosha Ekugadzira

● Kukanda kunoramba kuripo kunoteverwa nekuwedzera kwemvura inorema (huremu hwebhaa rimwe chete hunosvika matani 3–8) kunoita kuti pave nechimiro chakasimba chisina kudhonza maburi mudhayamita hombe.
● Kushanda kwekupisa/kutonhora kwakawanda pamwe chete nekunyoroveswa kwepakati kunodzorwa nemazvo kunobvisa chimiro chedendritic, zvichikonzera matrix ye α+(α+δ) eutectoid yakafanana ine saizi yegrain yakajairika 0.025–0.050 mm.
● Bhawa rese harina musono uye harina majoini muhurefu hwaro hwese.

Zvinhu Zvinonyanya Kukosha Pakudzora Hunhu

● Kuumbwa kwemakemikari: Kuongorora kwespectrometer (SPECTRO) kunoitwa pakupisa kwega kwega; zvinhu zvese zvinotevedzana (P, Fe, Sb, Bi, nezvimwewo) zvinodzorwa kusvika ku50% yemiganhu yakajairwa kana kuti yakasimba.
● Hunhu hwemakanika: Hunhu hwakajairika hwe Φ≥200mm bars: Simba rekudhonza ≥450 MPa, simba rekugovanisa 0.2% ≥200 MPa, kureba ≥15%, kuomarara HB120–180 (yakavimbiswa zvizere).
● Kugadzikana kwemukati: Kuongororwa kwe ultrasonic 100% padanho reASTM B594 Class A kana SEP 1921 E/e uchishandisa ma probe e 6–10 MHz. Mishumo yakazara yeUT uye mapikicha e macro/microstructure anowanikwa pabhawa rega rega kana ukakumbira.
● Kushivirirana kwemativi: Kushivirirana kwedhayamita ± 0.5 kusvika ± 1.5 mm (zviri nani pane H11), kutwasuka ≤1 mm/m, kushivirirana kwehurefu hwekucheka ± 20 mm.
● Kupera kwemusoro: Kunyatsogadziriswa mushure mekubuda, kuomarara kwemusoro Ra ≤3.2 μm, isina mitswe, zvidimbu, kana zvikanganiso zveganda reorenji.

Mareferensi Ezvekugovera

● Mapuropera makuru emugungwa (3–5 ton single CuSn10Zn2 bars)
● Makomputa emagetsi ane simba guru (CuSn6/CuSn8)
● Masisitimu emapaipi emvura yegungwa (C51900 dhayamita hombe)
● Bronze ine tin-phosphorus yakasimba kwazvo inoshandiswa pakufambisa njanji uye kushandisa simba remhepo

Nguva yekutumira zvinhu: Mazuva 30–45 ezvinhu zvakajairwa, mazuva makumi maviri ekutumira zvinhu nekukurumidza kuburikidza nehurongwa hwakatsaurirwa. Maitiro ekugadzira uye kuongororwa kwemhando yezvigadzirwa zvinogamuchirwa nguva dzose.
