C93200 Lub Raj Mis Tooj Liab Uas Muaj Hlau Loj - Cov Khoom Siv Qib Bearing

Cov Tooj Liab Loj Loj (Φ120mm thiab siab dua) - Kev Ntxiv Txog Kev Siv Tshuab

Peb tshwj xeeb hauv kev tsim cov hlau tooj liab loj uas muaj qhov loj li ntawm Φ120mm txog Φ650mm. Cov qib tseem ceeb suav nrog C51900, C52100, C51000, CuSn6, CuSn8, ZCuSn5Pb5Zn5, ZCuSn10Zn2, thiab lwm yam. Cov khoom siv tuaj yeem muab rau GB/T 13808, ASTM B505, JIS H3270, EN 1982, lossis hloov kho cov tshuaj lom neeg thiab cov khoom raws li cov neeg siv khoom xav tau.

Cov Txheej Txheem Tsim Khoom Tseem Ceeb

● Kev casting semi-continuous ua raws li kev extrusion hydraulic hnyav (ib qho bar hnyav 3–8 tons) ua kom muaj cov qauv ntom ntom yam tsis muaj qhov porosity shrinkage hauv cov kab uas loj.
● Kev ua haujlwm kub/txias ntau zaus ua ke nrog kev tswj hwm qhov nruab nrab annealing tshem tawm cov qauv dendritic, ua rau muaj homogeneous α+(α+δ) eutectoid matrix nrog cov noob loj li qub 0.025–0.050 hli.
● Tag nrho cov bar yog seamless thiab sib koom ua ke thoob plaws nws qhov ntev.

Cov Ntsiab Lus Tseem Ceeb ntawm Kev Tswj Xyuas Zoo

● Cov tshuaj lom neeg muaj pes tsawg leeg: Kev ntsuas Direct-reading spectrometer (SPECTRO) ua rau txhua qhov kub; txhua yam khoom me me (P, Fe, Sb, Bi, thiab lwm yam) tswj tau txog 50% ntawm cov kev txwv tus qauv lossis nruj dua.
● Cov khoom siv kho tshuab: Cov nqi ib txwm muaj rau Φ≥200mm tuav: Lub zog tensile ≥450 MPa, 0.2% lub zog tawm los ≥200 MPa, elongation ≥15%, hardness HB120–180 (tag nrho lav).
● Kev ruaj ntseg sab hauv: Kev kuaj ultrasonic 100% raws li ASTM B594 Class A lossis SEP 1921 E/e qib siv 6–10 MHz probes. Cov ntawv qhia UT tag nrho thiab cov duab macro/microstructure muaj rau txhua kab thaum thov.
● Kev kam rau qhov ntev: Kev kam rau txoj kab uas hla ±0.5 txog ±1.5 hli (zoo dua H11), kev ncaj ≤1 hli/m, kev kam rau qhov ntev ntawm kev txiav ±20 hli.
● Qhov chaw tiav: Ua kom raug tom qab extrusion, qhov roughness ntawm qhov chaw Ra ≤3.2 μm, tsis muaj kab nrib pleb, cov khoom tsis muaj, lossis cov teeb meem ntawm daim tawv txiv kab ntxwv.

Cov Lus Qhia Txog Kev Muab Khoom

● Cov kiv cua loj hauv dej hiav txwv (3–5 tuj ib qho CuSn10Zn2)
● Cov khoom siv hluav taws xob siab (CuSn6/CuSn8)
● Cov kav dej hiav txwv (C51900 txoj kab uas hla loj)
● Cov tooj liab tin-phosphor muaj zog heev rau kev thauj mus los ntawm tsheb ciav hlau thiab kev siv hluav taws xob los ntawm cua

Lub sij hawm ua khoom: 30–45 hnub rau cov khoom siv, 20 hnub ua tau rau cov xaj ceev los ntawm kev teem sijhawm tshwj xeeb. Cov txheej txheem Hoobkas thiab kev tshuaj xyuas zoo yeej ib txwm txais tos.
