Premium Pure Copper Square Bar - Precision Machining Npaj Txhij

Kev Txhais Lus Askiv Tshaj Lij: Txoj Kev Tsim Khoom (Kev Tswj Xyuas Tag Nrho Cov Txheej Txheem Tsis Siv Neeg)

1. Cov Khoom Siv Raw Xaiv Qib 1 cathode tooj liab (Cu-CATH-2) tau los ntawm cov nroj tsuag electrolytic tooj liab hauv Guizhou, Jiangxi, thiab lwm thaj chaw, nrog rau tag nrho cov khoom tsis huv uas tswj hwm nruj me ntsis ntawm ≤ 35 ppm.

2. Txheej Txheem Melting Ob lub cub tawg yaj siv lub zog-zaus + nruab nrab-zaus induction furnaces, tiv thaiv thoob plaws los ntawm cov neeg sawv cev sib xyaw ua ke ntawm charcoal + high-purity graphite, thiab tiv thaiv tag nrho nrog nitrogen / argon huab cua kom txo qis kev khaws cov pa oxygen. Cov ntsiab lus oxygen yaj tswj tau ruaj khov ntawm 5–15 ppm.

3. Kev Casting Semi-Continuous Kev casting txuas ntxiv mus rau sab saud (txheej txheem rub mus rau sab saud) nrog lub tshuab ua kom muaj graphite crystallizer siab. Cov kev teeb tsa traction tswj tau meej (qhov ceev rub, lub sijhawm nres, thiab lub sijhawm thawb rov qab sib dhos ua ke). Qhov hnyav ntawm cov khoom siv: 1.5–2.5 tons, ua kom ntseeg tau tias cov qauv noob sab hauv zoo thiab tsis muaj kev sib cais tseem ceeb.

4. Kev Tswj Xyuas Kub Peb-cheeb tsam roj-fired homogenizing cub tawg, cua sov sib xws ntawm 800–850 ° C, tuav lub sijhawm ≥ 4 teev, zoo tshem tawm cov porosity as-cast thiab kev sib cais compositional.

5. Kub Extrusion 3200–5000 tuj hydraulic xovxwm, extrusion piv 30–80, extrusion chim kub 750–800 ° C, tawm ceev 30–80 hli / s, ua rau qhov chaw tsis muaj txiv kab ntxwv-tawv qauv thiab ntom sab hauv microstructure.

6. Kos duab / Roller Leveling Multi-pass txias kos duab ua ke nrog nruab nrab-zaus annealing (580–620 ° C nyob rau hauv huab cua tiv thaiv). Dimensional kam rau siab ua tiav rau ± 0.10 hli, lossis ± 0.05 hli rau cov kev xav tau tshwj xeeb.

7. Ua tiav Rau-yob ncaj ncaj + centerless sib tsoo, ua tiav qhov roughness ntawm qhov chaw Ra ≤ 0.8 μm (Ra 0.4 μm muaj thaum cov neeg siv khoom thov).
