Vuam txoj kev ntawm nickel chromium hlau thiab npib tsib xee chromium ferroelectric kuj hlau alloy nyob rau hauv cov cua kub tubes
Kev ua tau zoo, siv 300 series stainless hlau vuam pas nrig tuaj yeem tiv thaiv txhuas oxidation, txo vuam kev ua tau zoo, thiab ua kom lub neej ua haujlwm luv. Thaum ua haujlwm kub qis dua 950 degree, nickel chromium lossis npib tsib xee chromium hlau alloy vuam rods tuaj yeem siv, lossis alloy vuam rods tuaj yeem siv. Thaum qhov kub siab tshaj 950 degree, tsuas yog siv cov electrodes tshwj xeeb. Thaum cov kev xav tau zoo siab, tsuas yog cov welding rods tuaj yeem siv rau vuam.
Cov txheej txheem vuam saum toj no feem ntau yog siv rau vuam cov khoom siv hluav taws xob cua sov thiab lwm yam khoom siv cua sov. Txawm li cas los xij, plasma arc vuam, electron beam welding, kuj vuam, thiab lwm yam vuam txoj kev yog tag nrho cov haum rau vuam Fe-CR-al hluav taws xob cua sov Cheebtsam vim hais tias cov vuam txoj kev no muaj ib tug yam ntxwv ntawm zoo thiab ntom.
Txoj kev loj hlob ntawm hluav taws xob cua sov alloy rau hluav taws xob cua sov raj
Kev tsim hluav taws xob cua sov tube alloy cov ntaub ntawv hauv Suav teb tau pib thaum xyoo 1950s, thaum tsuas yog ib qho me me ntawm NiCr thiab NiCr ferroalloy khoom tuaj yeem tsim tau. Nyob rau xyoo 1960, peb tau pib tsim thiab maj mam ua cov cuab yeej tsim khoom ntawm hlau chromium aluminium alloy hluav taws xob cua sov raj. Tom qab ntau tshaj 30 xyoo ntawm txoj kev loj hlob, Tuam Tshoj muaj peev xwm tsim tau ntau yam khoom cua sov, xws li hluav taws xob cua sov raj, hluav taws xob cua sov raj, thiab lwm yam khoom cua sov.
Muaj kaum ob lub cua sov alloy factories hauv Suav teb. Kev tsim tawm txhua xyoo yog kwv yees li 7000 tons, ntawm cov xaim nyiaj rau 65% thiab strip nyiaj rau 10%. Flat filaments thiab filaments suav txog 25%. Cov khoom specifications muaj xws li: hlau pas nrig 1-10 hli, sawb dav 5-100 hli, thickness 0 1-2.5 hli, filament 0 05-1 .0mm, thiab tiaj hlau dav 0.20-4. 0mm, thickness 0.05-1 00 hli. Khoom siv kub 500-1400 degree Khoom kub 500-1400 degree
Tuam Tshoj tau tsim tus qauv National Technical Standard for Electric Heating Alloy in Electric Heating Pipes (GB/t1234), uas txhua tus neeg tsim khoom siv siab ua. Cov hluav taws xob cua sov alloy hauv cov hluav taws xob cua sov raj uas tsim los ntawm peb lub tuam txhab kuj ua raws li cov txheej txheem thoob ntiaj teb (jisc2520), Astmb603, b344, din17470, thiab lwm yam, thiab feem ntau ntawm cov khoom tau mus txog qib siab thoob ntiaj teb. Tam sim no, qhov zoo ntawm cov khoom siv hluav taws xob cua sov tsim los ntawm peb lub tuam txhab yog maj mam txhim kho.
