Dab tsi yog cov txiaj ntsig ntawm kev siv Molybdenum Sheaths hauv Thermocouples rau Metallurgical Applications?

Molybdenum sheaths muab ci ntsa iab ntau dhau-kub tsis kam. Hauv cov txheej txheem metallurgical, qhov kub thiab txias tuaj yeem ncav cuag cov qib siab tshaj plaws. Molybdenum tuaj yeem tiv taus cov kub uas tsis muaj kev puas tsuaj loj, ua kom cov thermocouple nyob twj ywm thiab muaj tseeb. Piv txwv li, nyob rau hauv steelmaking furnaces los yog smelting ua hauj lwm, molybdenum sheathed thermocouples tuaj yeem ua haujlwm tau zoo ntawm qhov kub thiab txias siab tshaj 1500 degrees Celsius.
Lawv muab cov tshuaj tiv thaiv tsim nyog. Metallurgical ib puag ncig tsis tu ncua muaj kev tshaj tawm rau ntau cov tshuaj lom neeg thiab cov hlau molten. Molybdenum yog pov thawj tiv thaiv ntau yam corrosive, tiv thaiv cov thermocouple los ntawm kev puas tsuaj thiab ua kom qhov ntsuas kub kom raug. Qhov no yog qhov tseem ceeb tshaj plaws hauv txoj hauv kev uas muaj cov tshuaj lom neeg sib tw lossis cov hlau molten.
Molybdenum sheaths muaj ntau lub zog txhua yam. Cov pob zeb metallurgical tuaj yeem muaj cov neeg kho tshuab hnyav, nrog rau kev vibrations, cuam tshuam, thiab puas. Molybdenum yog ib daim ntaub ruaj khov uas tuaj yeem tiv thaiv cov rog, tiv thaiv cov thermocouple thiab ua kom nws lub neej ntev. Qhov no yog qhov tseem ceeb rau kev cia siab rau qhov ntsuas kub hauv cov chaw lag luam cuam tshuam.
Lawv muab cov thermal conductivity tsim nyog. Kev hloov pauv kom sov yog qhov tseem ceeb rau qhov ntsuas kub kom raug. Molybdenum muaj cov thermal conductivity ntau dhau, tso cai rau cov thermocouple kom ceev cov lus teb rau qhov kub thiab txias. Qhov no tshwm sim nyob rau hauv ntau qhov tseeb thiab zoo sij hawm nyeem ntawv kub, uas yog ib qho tseem ceeb rau kev tswj thiab optimizing metallurgical txoj kev.
