ʻO ke anawaena nui C93200 Leaded Tin Bronze Tube - Bearing Grade Alloy

ʻO ka ʻauamo keleawe tin nui (Φ120mm a ʻoi aku) - Hoʻohui loea

He loea mākou i ka hana ʻana i nā ʻaukā keleawe tini nui mai Φ120mm a i Φ650mm. ʻO nā papa nui e komo pū me C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, a pēlā aku. Hiki ke hoʻolako ʻia nā mea i GB/T 13808, ASTM B505, JIS H3270, EN 1982, a i ʻole e like me ke kemika a me nā waiwai i hoʻopilikino piha ʻia e like me nā koi o ka mea kūʻai aku.

Kaʻina Hana Hana Koʻikoʻi

● ʻO ka hoʻolei ʻana hapa-hoʻomau i ukali ʻia e ka extrusion hydraulic hana kaumaha (kaumaha ʻaukā hoʻokahi 3-8 tons) e hōʻoiaʻiʻo i ka hoʻonohonoho piha ʻana me ka ʻole o ka porosity shrinkage i nā anawaena nui.
● ʻO ka hana wela/anu multi-pass i hui pū ʻia me ka annealing waena i kāohi pono ʻia e hoʻopau i ka ʻano dendritic, e hopena ana i ka matrix eutectoid α+(α+δ) homogeneous me ka nui o ka palaoa maʻamau 0.025–0.050 mm.
● He humuhumu ʻole ka pā holoʻokoʻa a ʻaʻohe hono ma kona lōʻihi.

Nā mea nui o ka Mana Hoʻomalu Kūlana

● Hoʻohuihui kemika: Hana ʻia ka loiloi spectrometer heluhelu pololei (SPECTRO) ma kēlā me kēia wela; nā mea trace āpau (P, Fe, Sb, Bi, a pēlā aku) i kāohi ʻia i 50% o nā palena maʻamau a i ʻole paʻa.
● Nā waiwai mīkini: Nā waiwai maʻamau no nā kaola Φ≥200mm: Ikaika tensile ≥450 MPa, 0.2% ikaika hua ≥200 MPa, elongation ≥15%, paʻakikī HB120–180 (hōʻoia piha ʻia).
● Paʻa kūloko: 100% hoʻāʻo ultrasonic e like me ka pae ASTM B594 Papa A a i ʻole SEP 1921 E/e me ka hoʻohana ʻana i nā probes 6–10 MHz. Loaʻa nā hōʻike UT piha a me nā kiʻi macro/microstructure no kēlā me kēia pā ma ke noi.
● Nā ʻae ʻana o ke ana: ʻAe ʻana o ke anawaena ±0.5 a i ±1.5 mm (ʻoi aku ka maikaʻi ma mua o H11), pololei ≤1 mm/m, ʻae ʻana o ka lōʻihi ʻoki ±20 mm.
● Hoʻopau ʻili: Hoʻohuli pololei ʻia ma hope o ka extrusion, ʻo ka ʻoʻoleʻa o ka ʻili Ra ≤3.2 μm, ʻaʻohe māwae, nā hoʻokomo, a i ʻole nā ​​kīnā ʻili ʻalani.

Nā Kuhikuhi Hoʻolako

● Nā mea hoʻoneʻe moana nui (3–5 tona mau kaola CuSn10Zn2 hoʻokahi)
● Nā pilina haki kaapuni uila kiʻekiʻe (CuSn6/CuSn8)
● Nā ʻōnaehana paipu wai kai (C51900 anawaena nui)
● Keleawe tin-phosphor ikaika kiʻekiʻe no nā kaʻaahi a me nā noi makani

Ka manawa alakaʻi: 30-45 mau lā no nā mea maʻamau, hiki i nā lā 20 no nā kauoha wikiwiki ma o ka hoʻonohonoho manawa i hoʻolaʻa ʻia. Hoʻokipa mau ʻia ke kaʻina hana hale hana a me nā loiloi maikaʻi.
