Nta
● Kev tswj qhov kub thiab txias ntawm molten aluminium yog qhov txuas tseem ceeb hauv kev lag luam aluminium, yog li kev ntseeg siab ntawm cov cuab yeej ntsuas kub yog qhov tseem ceeb tshwj xeeb. SG-28 silicon nitride ceramic tau dav siv nyob rau hauv ntau zaus raws li lub thermocouple tiv thaiv raj.
● Vim nws qhov ua tau zoo ntawm qhov kub thiab txias, lub neej ua haujlwm ib txwm tuaj yeem ncav cuag ntau tshaj ib xyoos.
● Muab piv nrog cam khwb cia hlau, graphite, carbon nitrogen thiab lwm yam ntaub ntawv, silicon nitride yuav tsis corroded los ntawm molten aluminium, uas ua kom qhov tseeb thiab rhiab heev ntawm kev ntsuas kub ntawm txhuas.
● Silicon nitride ceramics muaj tsawg wettability nrog molten aluminium, txo qhov kev xav tau ntawm kev tu txhua hnub.
● Ua ntej kev teeb tsa, xyuas qhov nruj ntawm cov pob qij txha stainless hlau thiab cov ntsia hlau ntawm lub thawv sib txuas.
● Rau kev nyab xeeb, cov khoom yuav tsum tau preheated saum 400 ° C ua ntej siv.
● Txhawm rau ua kom lub neej ua haujlwm ntev ntawm cov khoom, nws raug nquahu kom ntxuav thiab tswj qhov chaw tsis tu ncua txhua 30-40 hnub.
Nta:
Kev kub siab ua haujlwm: Isostatically nias silicon carbide tiv thaiv cov raj tuaj yeem ua haujlwm txog li 2800 ° F (1550 ° C), ua rau lawv tsim nyog rau feem ntau cov kev siv kub kub.
Nto glaze txheej: Sab nrauv yog coated nrog tshwj xeeb silicon carbide glaze uas txo cov porosity thiab minimizes cov tshuaj tiv thaiv cheeb tsam nrog molten hlau, yog li ncua kev pab cuam lub neej ntawm lub raj tiv thaiv.
Corrosion resistance thiab thermal shock resistance: Lub raj tiv thaiv muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog thaum nyob rau hauv kev sib cuag nrog molten aluminium, zinc thiab lwm yam hlau, thiab tuaj yeem tiv taus slag yaig. Tsis tas li ntawd, nws zoo heev thermal shock kuj ua kom muaj kev ruaj ntseg thaum lub sij hawm hloov kub ceev.
Tsawg porosity: qhov porosity tsuas yog 8% thiab qhov ceev yog qhov siab, uas ntxiv rau cov tshuaj corrosion thiab tshuab zog.
Ntau yam specifications: Muaj nyob rau hauv ntau qhov ntev (12 "mus rau 48") thiab diameters (2.0" OD), thiab tuaj yeem nruab nrog 1/2 "los yog 3/4" NPT threaded kev sib txuas kom tau raws li cov khoom siv sib txawv.
Daim ntawv thov:
Aluminium smelting txheej txheem: Isostatically pressed silicon carbide tiv thaiv tube yog heev haum rau siv nyob rau hauv txhuas yaj, thiab nws anti-oxidation thiab high-temperature zog zoo ncua lub neej kev pab cuam ntawm lub thermocouple.
High-temperature industrial furnaces: Nyob rau hauv high-temperature furnaces los yog corrosive gas ib puag ncig, isostatic silicon carbide tiv thaiv tubes muab kev tiv thaiv mus sij hawm ntev los xyuas kom meej txhim khu kev qha kev lag luam ntawm thermocouples nyob rau hauv hnyav ib puag ncig.
Khoom zoo:
Txuas lub neej ntawm thermocouple thiab txo qhov zaus hloov
Zoo thermal conductivity, txhim kho qhov ntsuas kub kom raug
Zoo mechanical zog, siab tsis kam thiab hnav tsis kam
Tus nqi tu qis, tsim nyog rau kev ua haujlwm siab kub mus ntev
Isostatic silicon carbide thermocouple tiv thaiv raj yog qhov kev xaiv zoo tshaj plaws rau kev ntsuas kub niaj hnub no vim lawv qhov kev ua tau zoo thiab ua haujlwm ntev. Lawv tau dav siv nyob rau hauv high-temperature teb xws li casting, metallurgy, ceramics, thiab iav manufacturing
