Oxygen-dawb tooj liab kab: txheej txheem kev ua tau zoo thiab kev siv tseem ceeb ntawm cov tooj liab tsis muaj oxygen
Oxygen-dawb tooj liab yog tooj liab uas tsis muaj oxygen lossis ib qho deoxidizer residue. Oxygen-dawb tooj liab muaj cov hluav taws xob hluav taws xob zoo, kev ua haujlwm zoo, weldability, corrosion kuj thiab kub ua haujlwm, thiab tsis muaj hydrogen embrittlement. Oxygen-dawb tooj liab muaj cov cai nruj rau cov khoom siv. Raws li cov ntsiab lus tooj liab thiab cov khoom siv zoo, kuv lub teb chaws faib cov tooj liab tsis muaj oxygen rau hauv ob theem: TU1 thiab TU2.
Kev ua tau zoo ntawm cov hlau tsis muaj oxygen
1. Smelting thiab casting txheej txheem. Oxygen-dawb tooj liab yog tsuas yog smelted siv fais fab zaus cored induction furnaces. Txhawm rau kom ntseeg tau qhov zoo ntawm cov pa oxygen tsis muaj tooj liab, "concentrate sealing" yuav tsum ua tiav, uas yog, cov khoom siv raw yuav tsum yog electrolytic tooj liab uas muaj w (Cu) > 99.97% thiab w (Zn) < 0. 003%. Thaum lub sij hawm smelting, yuav tsum tau them nyiaj mloog kom txo tau qhov chaw ntawm cov pa, thiab Siv calcined charcoal los npog, thiab ib tug kab ntawm phosphorus kuj yuav ntxiv raws li ib tug deoxidizer. Cov ingots raug cam khwb cia siv ib tug semi-nruam casting txheej txheem nyob rau hauv nitrogen tiv thaiv los yog banquet cover. Qhov kub ntawm casting yog 1150-1180 degree .
2. Moulding kev ua tau zoo. Oxygen-dawb tooj liab muaj qhov txias txias thiab kub ua haujlwm zoo thiab tuaj yeem ncab, dov, extruded, khoov, punched, sheared, spun, chim siab, forged, forged, threaded, knurled, mob, thiab muaj zoo forgeability. Qhov zoo tshaj plaws yog 65% ntawm forged tooj dag. Thermal processing kub yog nqa tawm ntawm 800-900 degree .
3. Kev ua haujlwm vuam. Nws yog ib qho yooj yim los ua fusion vuam, mos soldering, brazing, roj shielded tungsten arc vuam, thiab roj shielded hlau arc vuam. Nws qhov kev ua tau zoo hauv cov pa roj carbon monoxide yog qhov zoo. Shielded hlau arc vuam thiab feem ntau kuj welding txoj kev tsis pom zoo.
4. Txiav thiab sib tsoo kev ua haujlwm. Lub machinability ntawm oxygen-dawb tooj liab yog 20% ntawm cov dawb-txiav tooj dag HPb63-3.
Qhov tseem ceeb ntawm kev siv tooj liab tsis muaj oxygen
Oxygen-dawb tooj liab muaj siab purity, zoo heev hluav taws xob conductivity, thermal conductivity, thermal ua kev ua tau zoo thiab vuam zoo, thiab tsis muaj los yog tsawg heev "hydrogen kab mob".
Feem ntau yog siv rau hluav taws xob lub tshuab nqus tsev ntsuas qhov chaw. Dav siv nyob rau hauv tsheb npav bar, conductive strips, waveguides, coaxial cables, nqus cov ntsaws ruaj ruaj, lub tshuab nqus tsev raj, transistor Cheebtsam, thiab lwm yam.
