Hom B Thermocouple Hlau
Txheej Txheem Cej Luam Khoom
Hom B thermocouple hlau yog ib qho thermocouple hlau muaj nqis ua tau zoo uas muaj ob lub platinum-rhodium alloys: ib ceg zoo nrog 30% rhodium thiab 70% platinum, thiab ib ceg tsis zoo nrog 6% rhodium thiab 94% platinum. Tsim los rau qhov chaw kub heev, nws yog qhov kub tshaj plaws ntawm cov thermocouples hlau muaj nqis, zoo heev hauv kev ruaj khov thiab kev tiv thaiv oxidation ntawm qhov kub tshaj 1500 ° C. Nws cov khoom sib xyaw ua ke ob-platinum-rhodium txo qhov kev poob los ntawm platinum evaporation, ua rau nws zoo tagnrho rau kev ntsuas kub ntev.
Cov Qauv Txheem
- Hom Thermocouple: B-hom (Platinum-Rhodium 30-Platinum-Rhodium 6)
- IEC Txheem: IEC 60584-1
- ASTM Tus Qauv: ASTM E230
- Xim Coding: Ceg zoo - grey; Ceg tsis zoo - dawb (ib qho IEC 60751)
Cov Nta Tseem Ceeb
- Kev Tiv Thaiv Kub Heev: Kub ua haujlwm ntev txog li 1600 ° C; siv luv luv txog li 1800 ° C
- EMF qis ntawm qhov kub qis: Qhov tso zis thermoelectric tsawg kawg nkaus hauv qab 50 ° C, txo qhov cuam tshuam ntawm qhov yuam kev sib tshuam txias
- Kev Ruaj Ntseg Siab Tshaj Plaws: ≤0.1% drift tom qab 1000 teev ntawm 1600 ° C
- Kev Tiv Thaiv Oxidation: Kev ua tau zoo heev hauv oxidizing atmospheres; tiv taus platinum evaporation
- Lub Zog Kho Tshuab: Tswj tau qhov ductility ntawm qhov kub siab, tsim nyog rau cov chaw ua haujlwm hnyav

Cov Lus Qhia Txog Khoom
| Khoom | Cov Lus Qhia Tshwj Xeeb |
|---|---|
| Ntev ib lub Spool | 5m, 10m, 20m (vim muaj cov hlau muaj nqis ntau) |
| Qhov Chaw Tiav | Annealed, kaj (tsis muaj kev ua qias tuaj ntawm qhov chaw) |
| Ntim Khoom | Ntim nrog lub tshuab nqus tsev kaw rau hauv cov thawv titanium uas muaj argon kom tiv thaiv kev oxidation |
| Kev kho kom raug | Tau taug qab mus rau cov qauv kub thoob ntiaj teb nrog cov kab EMF uas tau ntawv pov thawj |
| Cov Kev Xaiv Tshwj Xeeb | Kev txiav precision, polishing nto rau cov ntawv thov purity siab |
Cov Ntawv Thov Ib Txwm Muaj
- Cov cub tawg sintering kub heev (cov ntaub ntawv ceramic thiab refractory)
- Kev ua hlau smelting (superalloy thiab cov hlau tshwj xeeb tsim)
- Kev tsim iav (cov cub tawg iav uas ua los ntawm cov iav ntab)
- Kev sim tsav tsheb hauv aerospace (rocket engine nozzles)
- Kev lag luam nuclear (kev saib xyuas reactor kub siab)
Peb muab cov khoom sib dhos hom B thermocouple nrog cov raj tiv thaiv ceramic thiab cov khoom sib txuas kub siab. Vim tias cov khoom siv muaj nqis siab, qhov ntev ntawm cov qauv tsuas yog txwv rau 0.5-1m thaum thov, nrog rau daim ntawv pov thawj tag nrho thiab cov ntawv qhia txog kev tshuaj xyuas impurity. Kev teeb tsa tshwj xeeb rau cov chaw ua kom sov tshwj xeeb muaj.
