Cov yam ntxwv ntawm Tungsten-Rhenium Thermocouple

Tungsten-rhenium thermocouple yog qhov kub kub tiv thaiv thermocouple. Nws muaj qhov zoo ntawm txoj kev sib raug zoo ntawm kev sib raug zoo ntawm qhov kub thiab txias ntawm qhov kub thiab txias thiab muaj peev xwm, txhim khu kev qha thermal ruaj khov thiab tus nqi qis. Nws tuaj yeem ncaj qha ntsuas qhov kub ntawm cov kua, chav thiab roj nruab nrab thaum sib phim nrog cov twj paj nruag. Nws tuaj yeem hloov platinum-rhodium thermocouple raws li lub tshuab ntsuas kub me me Kev sib raug zoo ntawm thermoelectric muaj peev xwm thiab kub ntawm rhenium thermocouple conforms rau zbnoup kev qhia rau zbn {6} yog sib npaug rau Astme {7}} txheem. Nws tuaj yeem siv nyob rau hauv ntau ntawm {{8} degree hauv lub tshuab nqus tsev, txo thiab inert cua. Lub Tungsten-Rhenium khub nrog kev tiv thaiv tshwj xeeb kuj tseem siv tau ntev hauv 1600 degree, thiab nws tus nqi qis dua li platinum-rhodium-rhodium thermocouple.
Tungsten-rhenium thermocouple yog thawj zaug tsim los ntawm Goedecoke tau tsim los ntawm xyoo 1931 thiab yog qhov kev ua tiav ntawm kev tsim kho cov hlau thermocouple thermocouple tsim hauv 1960s thiab 1970s. Cov yam ntxwv ntawm tungsten-rhenium thermocouples yog: Kub electrode hlau muaj lub siab melting taw tes (3300 degree), qis vapor siab, thiab yog yooj yim heev rau oxidize; Nws muaj cov tshuaj ruaj khov nyob hauv qhov chaw tsis-oxidizing. Nws muaj lub zog hluav taws xob loj, muaj qhov siab tshaj plaws, thiab tseem ceeb tshaj plaws, nws pheej yig.
Lub tungsten-rhenium thermocouple qib yog w / (w {-3 Re) thiab (w}} dua) / (w} {7}} Re). Lub sijhawm ntev siv ntsuas kub yog 2000 ~ 2400 degree, thiab cov sij hawm luv siv kub yuav ncav cuag 3000 degree.
