Cov Tooj Liab Pure Copper Round Bar Loj Tshaj Plaws - Lub Zog Hnyav

Cov Lus Qhia Txog Kev Siv Rau Cov Hlau Loj Uas Tsis Muaj Pa oxygen (OFC)

(Tsab Ntxiv - Φ120 mm thiab siab dua, txog li Φ500 mm+ cov tuav hnyav)

Cov ntsiab lus hauv qab no yog sau tshwj xeeb rau cov neeg siv khoom loj hauv kev lag luam. Txhua cov lus hais yog qhov tseeb, raws li cov ntaub ntawv, thiab tuaj yeem txheeb xyuas tau. Tsis muaj cov lus hais txog kev lag luam, tsis muaj kev nyiam kev xav - cov khoom siv thev naus laus zis uas tsim nyog rau kev suav nrog ncaj qha rau hauv phau ntawv qhia khoom, cov vev xaib raug cai, lossis cov ntaub ntawv sib tw.

1. Cov Khoom Siv Raw thiab Melting Tsuas Yog Qib-A electrolytic cathode tooj liab (Cu ≥ 99.99%) ntsib GB / T 467 siv. Melting yog ua nyob rau hauv 50-120 tuj nruab nrab-zaus / fais fab-zaus induction furnaces rau oxygen-free tooj liab nrog kev tiv thaiv carbon tas mus li. Lub sijhawm tiag tiag online hydrogen / carbon monoxide analyzers siv thoob plaws hauv cov txheej txheem, tswj cov pa oxygen tooj liab molten ruaj khov ≤ 8 ppm thiab hydrogen ≤ 0.5 ppm, tshem tawm porosity thiab hydrogen embrittlement kev pheej hmoo los ntawm qhov chaw.

2. Txheej Txheem Casting Kev casting ntsug semi-continuous yog siv (ib qho ntawm ob peb lub tuam txhab tsim khoom hauv tsev uas muaj peev xwm casting ruaj khov ntawm ingots ≥ Φ600 mm). Qhov kub ntawm pwm txias yog sectional thiab adjustable; rub yog tswj los ntawm tag nrho servo-tsav ntau-point synchronized systems nrog pull-stop-reverse programs raug rau 0.1 vib nas this. Ib qho ingot ntev txog li 8 m thiab hnyav txog li 18 tons. Qhov nto tsis muaj qhov tawg longitudinal thiab txias kaw; qhov zoo sab hauv tas li ua tiav ≥ 99.3% Class A txais nyob rau hauv ultrasonic kuaj.

3. Kev Tsim Khoom Siv Extrusion Siv cov tshuab roj-hydraulic lossis dej-hydraulic uas muaj zog 8000–20,000 tuj kab rov tav siv rau kev rho tawm ib zaug xwb (extrusion ratio 25–45). Qhov kub ntawm lub thawv rho tawm raug tswj tsis pub dhau ±5 °C, cov pwm tau preheated rau 420–480 °C, thiab qhov ceev rho tawm tau kho tau ntawm 0.8–3.5 m/min. Cov txiaj ntsig thawj zaug tseem ruaj khov tshaj 92%. Qhov ntev tshaj plaws ntawm ib txoj kab yog 12 m, qhov ncaj ≤ 1.5 mm/m. Kev rho tawm ib zaug xwb tshem tawm cov qauv nplej ntxhib thiab cov khoom siv kho tshuab uas cuam tshuam nrog cov txheej txheem ntau hluav taws ib txwm muaj.

4. Kev Kho Mob Kub thiab Kev Ua Tiav Lub cub tawg kho cua sov kab rov tav tas mus li nrog qhov kub thiab txias sib npaug ± 3 ° C thiab 60 m thaj chaw ua kom zoo ua kom muaj cov qauv me me thiab cov khoom zoo sib xws raws li qhov ntev ntawm cov hlau. Cov kab ua tiav tau nruab nrog cov tshuab ncaj plaub-yob + rau-yob ua ke, ua tiav qhov ncaj kawg ≤ 0.5 hli / m. Kev tig tawv nqaij yog ua rau ntawm cov tshuab CNC hnyav, xa cov qhov roughness Ra ≤ 3.2 μm. Qhov chaw ci ntsa iab tsis muaj oxide tuaj yeem muab tau raws li qhov kev thov.

5. Kev Tswj Xyuas Zoo
● Kev tshuaj xyuas cov tshuaj lom neeg ntawm ib pawg khoom 100% los ntawm kev nyeem cov spectrometer ncaj qha (34 yam khoom)
● Kev kuaj ultrasonic ib-bar 100% (ua raws li SEP 1921 E/e lossis ASTM E428)
● Cov khoom siv kho tshuab tag nrho, qhov loj ntawm cov noob, thiab kev ntsuas eddy-current conductivity ua tiav rau ntawm lub taub hau, nruab nrab, thiab tus Tsov tus tw ntawm txhua txoj kab
● Kev sim ntxiv ntawm cov kab hluav taws xob helical eddy-current rau cov kab loj loj kom tsis txhob muaj cov kab nrib pleb me me ntawm qhov chaw thiab ze ntawm qhov chaw
● Kev nrhiav tau tag nrho MES + ERP: cov khoom siv raw → tus lej ingot → tus lej extrusion → tus lej bar tiav, kev sib txuas lus ib-rau-ib, taug qab tau tas mus li
1. Cov Ntaub Ntawv Kev Ua Tau Zoo Li Cas (qhov nruab nrab ntsuas tau tiag tiag, rau kev siv)
● Lub zog tensile: 220–260 MPa
● Kev ntev: 45–55%
● Kev ua hluav taws xob: 101–102.5% IACS (20 °C)
● Qhov loj ntawm cov noob: 0.015–0.035 hli
● Kub mos: ≥ 480 °C (qhov nyuaj poob ≤ 5 HV tom qab 1-teev annealing)

1. Kev Muaj Peev Xwm Xa Khoom Qhov loj me ntawm cov khoom lag luam: Φ120, 150, 180, 200, 250, 300, 350, 400, 450, 500 mm Lub sijhawm ua khoom sai tshaj plaws: 30 hnub rau cov khoom lag luam, 45–60 hnub rau cov qhov loj me kev cai Qhov hnyav ib qho bar siab tshaj plaws 18 tons, qhov ntev tshaj plaws 12 m Cov tuav tuaj yeem raug sawn rau qhov ntev ruaj khov lossis ntau qhov ntev raws li xav tau.

Peb tsis siv cov lus thov uas tsis muaj pov thawj xws li "kev huv huv kawg nkaus" lossis "ua tus thawj coj thoob ntiaj teb." Peb tsuas yog muab cov ntaub ntawv xeem tiag tiag los ntawm txhua qhov yaj, txhua qhov extrusion, thiab txhua txoj kab rau koj qhov kev txiav txim siab.

Koj tuaj yeem npaj mus ntsib lub Hoobkas lees txais, rov kuaj dua, lossis kev saib xyuas los ntawm lwm tus (SGS, PONY, Beijing General Research Institute of Nonferrous Metals, thiab lwm yam) uas nyob hauv peb lub Hoobkas txhua lub sijhawm.
— Qhov no yog qhov kev cog lus ruaj khov tshaj plaws uas peb ua rau cov neeg siv khoom loj.

Yog tias koj xav tau kev hloov kho cov lus qhia txog kev siv tshuab (xws li kev ceev faj dua lossis kev nruj dua), lossis xav ntxiv cov ntawv pov thawj tshwj xeeb (AS9100, IATF16949, PED 2014/68/EU, thiab lwm yam), thov qhia rau kuv paub thiab kuv yuav hloov kho raws li qhov tsim nyog.
