Dab tsi yog cov ntawv thov tseem ceeb rau tungsten-rhenium thermocouples?

Ntau hom ntawm thermocouples yog siv nyob rau thaj tsam ntawm ntsuas kub ntsuas nyob ntawm qee qhov kev siv. Nrog rau lawv cov yam ntxwv tshwj xeeb, tungsten-rhenium thermocouples tau ua ib qho tseem ceeb hauv ntau cov haujlwm sib txawv thiab kev ua haujlwm.
Cov ntawv thov nyob rau hauv high-furnaces yog ib qho chaw seem tungsten-rhenium thermoco thermocouples Nrhiav tau tus nqi zoo. Feem ntau mus txog 2300 degree, cov thermocouples tuaj yeem tiv taus ntau kub siab. Kev soj ntsuam qhov tseeb ntawm qib siab yog qhov tseem ceeb hauv kev ua kom muaj kev muaj cov kev ua si xws li steelmaking lossis cov haujlwm ua haujlwm, melting hlau txheej txheem. Los ntawm ua tib zoo taug qab qhov kub thiab txias rau hauv cov chaw ua cua sov, tungsten-rhenium thermoco thermocoucles pab cov txheej txheem cua sov. Qhov no lav tias cov cuab yeej siv hlau tau yaj thiab kho qhov zoo tshaj plaws kub, yog li cuam tshuam cov txiaj ntsig zoo thiab cov yam ntxwv ntawm cov txiaj ntsig zoo.
Ib qho kev siv tseem ceeb ntxiv yog nyob rau hauv ib lub chaw aerospace. Cov dav hlau lub cav sim thiab kev ua haujlwm yuav ua rau kub kom nce qib siab dua. Ntau lub cav sib xyaw ua ke, suav nrog kev sib txuas ntawm chav thiab turnium tuaj, muaj lawv cov ntsuas kub siv tungsten-rhenium thermocouples. Los ntawm txoj kev sau cov ntaub ntawv los ntawm cov thermocouples, engineers yuav ntsuas cov teeb meem cav cav, thiab ua tau ib qho kev kho uas yuav tsum tau kho kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Hauv qhov kev lag luam tseem ceeb no, lawv tseem ceeb heev vim tias lawv lub peev xwm tiv thaiv cov kub thiab muaj kev txhim khu kev qha ib puag ncig.
Hauv txoj kev tshawb fawb txuj ci tshawb fawb, tshwj xeeb tshaj yog cov kev tshawb fawb kub, tungsten-rhenium thermocouples tseem ceeb heev. Nyob rau hauv cov ntaub ntawv tshawb fawb, piv txwv li, cov thermouvoely los saib xyuas kub tus cwj pwm ntawm cov ntaub ntawv ntawm cov ntaub ntawv ntawm cov khoom kub siab. Qhov no pab kom tau txais txiaj ntsig zoo dua li cas cov ntaub ntawv cuam tshuam los ua kom sov, uas yog qhov tseem ceeb tshaj plaws rau kev tsim cov khoom tshiab nrog kev txhim kho zoo. Seb ib tug yog tshawb xyuas theem hloov chaw ntawm cov hlau lossis thermal conductivity ntawm ceramics, muaj peev xwm ntawm kev pom zoo ntawm tungsten-rhenium thermocouples.
Cov iav ua rau lub sector tseem pom siv rau tungsten-rhenium thermocouples. Xav tau qhov kub thiab txias yog xav tau nyob rau hauv iav ua rau yaj cov khoom siv raw thiab tsim cov iav. Qhov kub nyob rau hauv lub melting rauv thiab annealing ncu yog saib xyuas siv cov thermocouples. Qhov tseeb ntsuas kub pab cov chaw tsim khoom kom muaj peev xwm lav tau tias cov iav tau yaj thiab txias ntawm tus nqi yog, yog li zam cov flasness xws li pob txha tsis sib xws. Los ntawm dog dig iav rau cov kws tshaj lij kho qhov muag iav, qhov no yooj yim tsim cov kev tsim cov khoom siv cov iav hwm.
Tsis tas li ntawd siv rau kev saib xyuas kub thiab txias hauv kev ua haujlwm nuclear, uas muaj ntau txoj haujlwm tshwm sim hauv kev mob siab, tungsten-rhenium thermocouples. Lawv muab cov ntaub ntawv ntsuas kub xws li ua kom muaj kev nyab xeeb khiav ntawm cov nroj tsuag raws li lawv tuaj yeem muaj sia nyob ib puag ncig kev ua haujlwm thiab hluav taws xob hauv kev ua kom muaj zog.
Thaum kawg, vim hais tias ntawm nws cov peev xwm zoo tshaj plaws kom pom qhov kub siab ntawm qib siab, tungsten-rhenium thermoco thermocouples pom ntau yam kev siv tseem ceeb. Los ntawm kev tshawb fawb txog cov iav ua lag luam thiab cov tshuab cua sov yog qhov chaw ua haujlwm kom yog, kev tswj hwm zoo, thiab kev nyab xeeb ntawm ntau cov haujlwm. Nyob rau hauv cov xwm txheej kub siab-kub, lawv cov kev tshwj xeeb ua rau lawv tsis pom qhov ntsuas kub.
