Kev ceev faj thaum siv Resistance Winding Fecral {{0}}cr21al6nb 0cr25al5 Kauv Coil Heating Hlau

1. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm Resistance Winding Fecral 0cr21al6nb 0cr25al5 Kauv Coil Heating Hlau yog hais txog qhov kub thiab txias ntawm cov hlau nws tus kheej hauv huab cua qhuav, tsis yog qhov kub ntawm lub cub tawg lossis cov khoom raug cua sov. . Feem ntau, qhov kub ntawm qhov chaw yog li ntawm 100 degrees siab tshaj qhov kub ntawm qhov cub. Yog li ntawd, xav txog cov laj thawj saum toj no, yuav tsum tau them nyiaj rau nws qhov kub thiab txias thaum tsim hluav taws xob cua sov hlau. Thaum qhov kev khiav hauj lwm kub dhau ib qho kev txwv, oxidation tus nqi ntawm cov hlau nws tus kheej accelerates thiab cov cua kub kuj txo, tshwj xeeb tshaj yog cov hlau chromium txhuas hluav taws xob cua sov alloy hluav taws xob cua sov hlau yog feem ntau deformation, vau, thiab txawm tawg, uas shortens nws cov kev pab cuam lub neej. .
2. Kev ua haujlwm siab ntawm cov hluav taws xob cua sov xaim kuj tseem muaj feem xyuam nrog cov kab hluav taws xob ntawm cov hluav taws xob cua sov. Feem ntau, txoj kab uas hla ntawm cov hluav taws xob cua sov hlau yuav tsum tsis pub tsawg tshaj 3 hli, thiab lub thickness ntawm lub tiaj tiaj yuav tsum tsis pub tsawg tshaj 2 hli.
3. Cov huab cua corrosive nyob rau hauv lub cub tawg kuj zoo sib xws rau lub siab ua hauj lwm kub ntawm hluav taws xob cua sov hlau, thiab feem ntau cuam tshuam rau kev khiav hauj lwm kub thiab kev pab cuam lub neej ntawm hluav taws xob cua sov hlau vim muaj corrosive cua.
4. Hlau chromium aluminium, npib tsib xee txhuas, thiab lwm yam ntawm cov hluav taws xob cua sov alloys, vim lawv cov tshuaj sib txawv, muaj qhov sib txawv ntawm daim ntawv thov kub, kev ua haujlwm antioxidant, thiab hluav taws xob tiv thaiv, uas txiav txim siab qhov ntev ntawm daim ntawv thov kub thiab kev pab cuam lub neej. Nyob rau hauv cov hlau chromium txhuas hluav taws xob cua sov alloy cov ntaub ntawv, cov khoom uas txiav txim siab hluav taws xob resistivity yog AL lub caij, thaum nyob rau hauv nickel chromium hluav taws xob cua sov alloy cov ntaub ntawv, cov khoom uas txiav txim siab hluav taws xob resistivity yog Ni lub caij. Thaum qhov kub thiab txias, cov oxide zaj duab xis tsim rau ntawm qhov chaw ntawm cov hlau hluav taws xob cua sov kuj muaj hnub nyoog thiab kev puas tsuaj tsis tu ncua. Cov ntsiab lus sab hauv ntawm nws cov hluav taws xob cua sov hlau yog tas li noj. Piv txwv li, AL, Ni, thiab lwm yam, thiab tom qab ntawd ua rau lub neej ua haujlwm luv luv, yog li ntawd, thaum xaiv txoj kab uas hla, cov lus qhia loj ntawm cov xaim lossis cov tuab tuab yuav tsum tau siv.
5. Vim muaj qhov kub thiab txias tsis tshua muaj zog ntawm cov hlau chromium aluminium, Resistance Winding Fecral 0cr21al6nb 0cr25al5 Kauv Coil Heating Hlau yog qhov ua rau deformation ntawm qhov kub thiab txias. Kev xaiv tsis raug lossis kev teeb tsa ntawm txoj kab uas hla ntawm cov xaim hlau tuaj yeem ua rau cov hluav taws xob cua sov xaim tawg thiab luv luv vim qhov kub thiab txias deformation. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xav txog nws cov ntsiab lus thaum tsim hluav taws xob cua sov hlau.
