Kev piav qhia
Nickel alloy hlau rau cua sov caij muaj cov khoom siv zoo heev, muaj zog tiv thaiv corrosion nyob rau hauv ib puag ncig, thiab cov khoom sib nqus, kev hloov pauv kub, siab conductivity, tsis tshua muaj roj ntim thiab tsis muaj vapor siab. Resistance cua sov hlau kuj muaj qhov chaw vuam zoo thiab lub zog tensile siab. Thaum tshav kub kub resistant hluav taws xob hlau tsuas yog siv nyob rau hauv lithium roj teeb, roj teeb pob ntseg, hlau stamping qhov chaw, hluav taws xob tsheb, nickel roj teeb, kev sib txuas lus, hluav taws xob nqus tsev vacuum, tshwj xeeb qhov muag teev thiab lwm yam lag luam.
Nickel-Chromium (Ni-Cr) Alloy yog ib qho ntawm cov khoom siv dav tshaj plaws rau cov khoom siv cua sov vim nws cov ductility, siab resistivity, thiab oxidation kuj txawm nyob rau hauv high kub. Cov feem ntau muaj pes tsawg leeg ntawm nickel-chromium alloys yog 80/20 los yog 80% npib tsib xee, 20% chromium. Lwm cov ntaub ntawv muaj nyob ntawm tus neeg tsim khoom.
Nichrome kuj xaim muaj hluav taws xob zoo thiab kev tiv thaiv corrosion, nws qhov siab melting point, nyob rau hauv qhov kub ntawm kev ua haujlwm ntawm cathode, evaporation; Muaj cov cua sov txaus evaporation, thiab muaj kev ua haujlwm zoo thiab kev tsim khoom; Nickel Hlau 200 Nichrome Alloy cua sov ua haujlwm muaj txiaj ntsig zoo rau kev tawm ntawm cov cathode, thiab muaj qhov tsim nyog resistivity, zoo hluav taws xob coefficient thiab loj kub conduction coefficient. Yog li ntawd, nws yog tsuas yog siv rau corrosion resistant Cheebtsam.
Cov txheej txheem tseem ceeb ntawm kev npaj nickel tsis kam alloy hlau yog siv lub tshuab nqus tsev ua ke nrog electroslag remelting, tom qab ntawd nrum cov hlau ingot rau hauv kub forging billet, polish lub billet finely, thiab ces ua kub dov ua. Tom qab cua sov kho cov kub- dov puag ncig tuav, rov qab kos cov hlau, thiab tom qab ntawd ua hydrogen tiv thaiv kev kho cua sov thiab annealing kom txog thaum nws tau rub mus rau cov xaim tiav lawm. Thaum kawg, ua hydrogen tiv thaiv tshav kub kho thiab annealing dua.
Tam sim no, tsis muaj cov qauv kev lag luam rau nickel resistors thiab nickel resistor hlau cov ntaub ntawv hauv peb lub teb chaws. Los ntawm ntau qhov kev hloov kho ntawm lub hauv paus muaj pes tsawg leeg ntawm nickel dilute alloys thiab kev siv cov txheej txheem kho cua sov kom tsim nyog, cov khoom siv nickel resistor hlau tsim nyog rau qee qhov ntsuas kub tau ua tiav tiav. Cov txiaj ntsig kev sim qhia tau hais tias qhov ntsuas kub tsis kam coefficient ntawm cov khoom tsim nickel resistor hlau yog 0.00586 / C, ua tau raws li cov kev cai siv. Qhov kev ua tau zoo ntawm cov khoom siv hlau yog qhov ruaj khov thiab tsim nyog rau kev tsim cov pa nickel resistive kub sensors.
Nickel alloy hlau rau cua sov caij tuaj yeem faib ua N4 thiab N6 hom raws li cov khoom siv.
Hauv cov ntawv thov kev lag luam, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, cov nickel resistors tuaj yeem hloov pauv platinum resistors thiab muaj cov ntawv thov dav dav. Raws li qhov xwm txheej ib txwm muaj, cov khoom siv tshuaj lom neeg ntawm cov xov tooj nickel yog qhov ruaj khov. Tsis tas li ntawd, cov xov hlau nickel tuaj yeem tsim cov txheej ntom ntom ntawm nickel oxide ntawm lawv qhov chaw, uas muab kev tiv thaiv.
Qhov tsis kam ntawm cov hlau thiab alloys nce nrog qhov kub thiab txias, tab sis feem ntau, qhov kub thiab txias coefficients ntawm siab - purity hlau thiab tsis tshua muaj alloys loj dua. Cov nickel kuj xaim uas siv rau kev ntsuas kub yog feem ntau yog ua los ntawm cov npib tsib xee ntshiab, uas muaj kev ruaj ntseg siab. Qhov kub tsis kam coefficient ntawm alloy tuaj yeem hloov kho los ntawm kev ntxiv me me ntawm cov ntsiab lus alloying.
N4 interchange ntshiab nickel hlau
N4 nichrome kuj xaim muaj lub zog zoo txhua yam, kev tiv thaiv corrosion thiab kub kub ua haujlwm, haum rau kev tsim cov khoom siv nqus tsev, cov khoom siv hluav taws xob, tshuaj lom neeg ntawm cov tshuaj muaj zog alkali, thiab lwm yam.
N4 nichrome kuj hlau yog tsim rau xov tooj cua, hluav taws xob lub teeb qhov chaw, mechanical manufacturing, tshuaj lom neeg kev lag luam, yog ib qho tseem ceeb structural khoom nyob rau hauv lub tshuab nqus tsev twj.
N6 nichrome hlau rau cua sov
N6 nickel hlau yam ntxwv: N6 npib tsib xee hlau ntxiv rau lub cev thiab tshuaj lom neeg ntawm cov hlau npib tsib xee, tab sis kuj muaj zog alkali tsis kam, nruab nrab thiab tsis muaj zog acid, thiab nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv. Nws yog tsuas yog siv los ua txhua yam ntawm cov khoom muaj zog alkali resistant, thiab nws cov khoom zoo li lub raj, phaj, pas nrig, siv, hlau thiab lwm yam.
