Nyob rau hauv ib lub caij nyoog uas qhov kev ua kom raug, kev ruaj khov, thiab kev ua haujlwm zoo txhais tau tias kev vam meej hauv kev lag luam,hlau nichrometseem sawv ntsug ua lub hauv paus ntawm kev tsim kho tshiab thermal. Ua los ntawm nickel (55–78%) thiab chromium (15–23%), nrog rau cov hlau thiab manganese me me, cov khoom tshwj xeeb no ua rau nws tsis tseem ceeb thoob plaws kev lag luam - los ntawm cov khoom siv hauv tsev mus rau kev tsim kho aerospace. Ntawm no, peb tshawb nrhiav ntau yam kev siv ntawm nichrome hlau thiab nws lub luag haujlwm hauv kev tsim cov thev naus laus zis cua sov niaj hnub.

 

Cov Khoom Tseem Ceeb Tsav Nichrome's Versatility

Tus nqi ntawm Nichrome nyob rau hauv nws qhov sib npaug zoo ntawm cov yam ntxwv ntawm lub cev thiab hluav taws xob. Nrog rau qhov tsis kam ntawm 1.0–1.1 × 10⁻⁶ Ω·m thiab qhov chaw yaj tshaj 1400 ° C315, nws hloov pauv lub zog hluav taws xob mus rau hauv cua sov thaum tiv taus oxidation thiab corrosion txawm tias nyob rau hauv cov xwm txheej hnyav. Nws tsis yog magnetic xwm, ductility, thiab qis thermal expansion ntxiv txhim kho nws adaptability315. Cov yam ntxwv no ua kom muaj kev ua tau zoo hauv cov chaw ib puag ncig uas xav tau kev ntseeg siab, los ntawm cov cub tawg kub kub mus rau cov khoom siv kho mob precision.

 

Cov Ntawv Thov Tseem Ceeb ntawm Nichrome Wire

1. Cov Khoom Siv Hauv Tsev

Hlau Nichrome yog lub hauv paus ntawm cov khoom siv cua sov txhua hnub. Cov tshuab ci qhob cij, cov tshuab ziab plaub hau, qhov cub, thiab cov lauj kaub hluav taws xob vam khom nws lub peev xwm los tsim cov cua sov sai thiab sib npaug. Piv txwv li,nichrome 60yog siv dav hauv cov khoom siv hluav taws xob nruab nrab xws li cov grills thiab cov cua sov cia khoom, thaum nichrome 80 (Ni80Cr20) zoo tshaj plaws hauv cov ntawv thov siab xws li cov cua sov dej thiab cov hlau soldering vim nws cov oxide adhesion zoo dua thiab lub neej ntev 915.

2. Kev Lag Luam thiab Kev Tsim Khoom

Hauv cov chaw ua haujlwm, cov hlau nichrome muab zog rau cov cub hluav taws xob, cov kilns, thiab cov khoom siv ua kom sov. Nws txoj kev tiv thaiv creep - khaws cia cov qauv ruaj khov hauv qab kev ntxhov siab ntev ntawm qhov kub siab dua 400 ° C - ua rau nws zoo tagnrho rau kev annealing, yaj, thiab kev kho cua sov 315. Cov lag luam xws li metallurgy thiab ceramics siv nichrome strips thiab coils rau lawv qhov ruaj khov hauv kev txo cov huab cua, zam cov teeb meem zoo li "ntsuab rot" pom hauv lwm cov alloys 9.

 

3. Kev Siv Tshuab Aerospace thiab Automotive

Nichrome qhov kev ntseeg tau nthuav dav mus rau qhov chaw xav tau xws li aerospace de-icing systems, engine sensors, thiab cabin heaters. Nws lub peev xwm los tiv taus thermal cycling thiab cov xwm txheej hnyav ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo hauv cov khoom tseem ceeb15. Cov ntawv thov automotive suav nrog lub rooj zaum sov thiab cov xov hlau defrosting, qhov twg nichrome 30 thiab 40 variants muab cov cua sov ruaj khov, txuag hluav taws xob9.

4. Cov Khoom Siv Kho Mob thiab Cov Khoom Siv Kuaj Mob

Hauv kev kho mob, nichrome hlau ua rau muaj kev tswj cua sov kom raug hauv cov cuab yeej phais, cov ntaub qhwv cua sov, thiab cov khoom siv tua kab mob. Cov chaw soj nstuam siv nws qhov tsis muaj zog rau kev sim nplaim taws thiab kev kub hnyiab ntawm cov tshuaj reactive, txo qis kev pheej hmoo ntawm kev ua qias tuaj715.

5. Kev Tsim Kho Tshiab thiab Kev Dais Teeb Meem Tshwj Xeeb

Kev nce qib hauv nichrome alloys tsom mus rau kev txhim kho kev ua haujlwm los ntawm kev sib xyaw ua ke thiab cov txheej txheem tsim khoom. Piv txwv li, vacuum-induction melting tsim cov qib zoo li Ni80Cr20-VI, optimized rau cov khoom siv hluav taws xob muaj kev ntseeg siab3. Tsis tas li ntawd, nichrome lub luag haujlwm hauv cov khoom siv hluav taws xob txuag hluav taws xob thiab cov tshuaj tsuag thermal qhia txog nws lub peev xwm hauv kev lag luam ruaj khov15.

 

Xaiv Cov Hlau Nichrome Zoo

Kev xaiv qib thiab qhov ntsuas kom haum yuav tsum tau soj ntsuam qhov kub thiab txias ua haujlwm, tej yam kev mob ib puag ncig, thiab cov lus qhia txog hluav taws xob. Cov xov hlau nyias dua (qhov ntsuas siab dua) haum rau cov kev xav tau kev tiv thaiv siab, thaum cov qauv tuab dua tswj cov khoom thauj tam sim no ntau dua15. Rau qhov chaw ib puag ncig hnyav, nichrome 70 thiab 80 muab kev ruaj khov tsis sib xws, thaum nichrome 20 sib npaug tus nqi thiab kev ua tau zoo rau cov davhlau ya nyob twg hluav taws xob9.

 

Kev Xav Txog Kev Nyab Xeeb thiab Kev Ruaj Ntseg

Txawm hais tias nichrome qhov kev tiv thaiv cua sov txo qhov xav tau kev saib xyuas, kev tuav kom zoo tseem ceeb heev. Kev rwb thaiv tsev, cov tswj kub, thiab kev tshuaj xyuas tsis tu ncua txo qhov kev pheej hmoo ntawm kev kub dhau thiab kev phom sij hluav taws xob15. Ntxiv mus, nws lub neej ntev thiab kev siv rov qab ua ke nrog kev siv zog thoob ntiaj teb los txo cov khib nyiab hauv kev lag luam.
