thermocouple

Detailed kev taw qhia

Nyob rau hauv cov txheej txheem ntawm smelting thiab kub preservation ntawm txhuas thiab txhuas alloys, qhov kub thiab txias ntawm molten aluminium thiab molten aluminium yog lub ntsiab tseem ceeb los xyuas kom meej cov khoom zoo ntawm txhuas.Nws tuaj yeem zam oxidation los ntawm overburning ntawm molten aluminium thiab molten aluminium, yog li txuag lub zog noj.Rau casting ntawm molten aluminium thiab molten aluminium,tNws kub yog feem ntau yog li 720 ° C.Txhawm rau kom ntseeg tau tias cov kua txhuas txhuas thiab cov dej txhuas tau khaws cia ntawm qhov kub thiab txias, cov kua txhuas txhuas cov dejthermocoupleplays lub luag haujlwm tseem ceeb raws li qhov ntsuas kub ntsuas ncaj qha rau hauv cov kua txhuas thiab cov dej txhuas los ntsuas qhov ntsuas kub.

Ua ntej ntawm tag nrho cov, kev nkag siab ntawm cov kua txhuas, kua hlau txhuas yog cov nquag nquag, cov permeability ntawm txhuas atoms muaj zog, thiab nws yog heev corrosive rau hlau.Cov oxide zaj duab xis interlayer muaj ntau cov hydrogen atoms, uas tuaj yeem yooj yim ua raws li cov khoom hlau thiab corrode cov hlau.

Raws li cov laj thawj saum toj no, nws yog ib qho tseem ceeb heev rau aluminium kua thiab txhuas dej ntsuas kub ntsuas thermocouple siv cov khoom siv uas tiv taus corrosion ntawm txhuas kua thiab txhuas dej ua cov thermocouple tiv thaiv raj.Cov hlau-raws li alloy thermocouple tiv thaiv raj lossis Si3N4 ua ke SiC thermocouple tiv thaiv raj,uyog qhov ua tau zoo armored thermocouples ua qhov ntsuas kub ntsuas.Nws muaj lub zog siab, muaj zog corrosion kuj, luv thermal teb lub sij hawm, kev pab lub neej ntev thiab ntsuas kub tsis tu ncua rau 24 teev.

Feem ntau haum rau kev ntsuas kub hauv aluminium ua thiab txhuas electrolysis industrie.

[Txoj kev kho]: Nws tuaj yeem kho nrog flange ruaj khov (customized flange loj)

Lub raj tiv thaiv yog ua los ntawm stainless hlau los ntawm lub neej ntawd.Rau kev ntsuas ntev tshaj li 800 degrees, nws raug pom zoo tias cov raj tiv thaiv tuaj yeem kho nrog 2520 cov khoom, GH3030 thiab GH3039 cov khoom, thiab kev tiv thaiv corrosion tuaj yeem kho nrog 316L khoom.Nws raug nquahu kom siv 2.0mm lossis 2.5mm rau cov kab uas hla ntawm 800 ℃.Cov txheej txheem tiv thaiv ib leeg tuaj yeem siv rau kev ntsuas kub ntawm cov pa taws hauv qhov cub, thiab qhov sib ntxiv ntawm silicon carbide tuaj yeem siv rau kev ntsuas kub ntawm cov tshuaj hlau.

Lub raj sab hauv yog ua los ntawm cov hlau tsis muaj steel, thiab lub raj sab nrauv tuaj yeem nruab nrog silicon carbide tiv thaiv raj, uas yog recrystallized silicon carbide.Sab nrauv ntawm ob txheej txheej casing yog cuam tshuam-resistant thiab corrosion-resistant.Nws yog tsuas yog siv nyob rau hauv metallurgy, tshuaj lom neeg kev lag luam, thiab non-ferrous hlau smelting.Nws yog tshwj xeeb tshaj yog haum rau ntsuas kub ntawm molten aluminium thiab tooj liab.Vim nws qhov siab ceev, nws yuav tsis raug eroded los ntawm molten aluminium thaum ntsuas kub;nws muaj qhov zoo thermal poob siab tsis kam, rwb thaiv tsev thiab oxidation tsis kam, hnav tsis kam thiab kub tsis kam, thiab lub neej ua haujlwm ntev.
