1, zitsulo zopangira zitsulo m'dziko lonselo
2, makampani ogwirizana a zitsulo mphero
3, makampani amalonda akunja okhala ndi kasitomala
Mawu Oyamba: mpweya wa chitsulo chosungunula umakhudza kwambiri mtundu wa chitsulo chosungunuka, zokolola, ndi kuchuluka kwa magwiritsidwe ntchito ndi ferroalloy. Monga kukula kwa chitsulo chosungunuka, chitsulo chokhazikika, chitsulo chosalekeza chopanda zitsulo zotayidwa ndi aluminium deoxidation ndi luso loyenga lakunja lazitsulo zosungunuka zimagwiritsidwa ntchito kwambiri, m'pofunika kuwerengera mpweya wa okosijeni muzitsulo zosungunuka mofulumira, zolondola komanso zachindunji, kuti muzitha kulamulira ntchito zopangira zitsulo, kusintha khalidwe, ndi kuchepetsa kumwa.
Kuti akwaniritse zomwe zili pamwambazi, probe ya okosijeni idapangidwa ngati njira yowunikira zitsulo zoyezera kuchuluka kwa okosijeni muchitsulo chosungunuka ndi kutentha kwachitsulo chosungunuka.
1, Ntchito:
Amagwiritsidwa ntchito pa LF, RH ndi malo ena oyeretsera, ma probe a okosijeni amayesa ntchito ya okosijeni yomwe ikufika pamasiteshoni komanso pochiza, zomwe zingatsimikizire kuwonjezereka kwa deoxidizer, kufupikitsa nthawi yoyenga, kuthandizira kupanga mitundu yatsopano, kukonza luso lamakono, ndikulimbikitsa chiyero chachitsulo.
2, Zofunikira Zazikulu ndi Kusiyanasiyana kwa Ntchito
Kufufuza kwa okosijeni kuli ndi mitundu iwiri: kupendekera kwa okosijeni wambiri ndi kupendekera kwa okosijeni kochepa. Yoyamba ndi
amagwiritsidwa ntchito kuyeza kutentha ndi kuchuluka kwa okosijeni wazitsulo zosungunuka mu converter, ng'anjo yamagetsi, ng'anjo yoyenga. Pambuyo pake amagwiritsidwa ntchito kuyeza kutentha ndi mpweya wambiri wa zitsulo zosungunuka mu LF, RH, DH, tundish, etc.
3, Kapangidwe
4, Mfundo:
"Solid dielectric concentration cell cell oxygen-content test" idagwiritsidwa ntchito mu kafukufuku wa okosijeni, womwe umalola kuyeza kutentha ndi mpweya wa chitsulo chosungunuka nthawi imodzi. Pulojekiti ya okosijeni imakhala ndi theka la cell ndi thermocouple.
Mayeso olimba a dielectric cell cell oxygen-content amapangidwa ndi theka-maselo. momwe selo imodzi imadziwika kuti imakhudza mpweya pang'ono, ndipo ina ndi chitsulo chosungunuka. Awiri theka-maselo olumikizidwa ndi oxygen ayoni olimba electrolyte, kupanga mpweya ndende selo. Mpweya wa okosijeni ukhoza kuwerengedwa kuchokera ku mphamvu ya okosijeni yoyezedwa ndi kutentha.
5, mawonekedwe:
1) Ntchito ya okosijeni ya chitsulo chosungunuka imatha kuyeza mwachindunji komanso mwachangu, zomwe zimathandiza kudziwa kuchuluka kwa deoxidizing agent, ndikusintha magwiridwe antchito a deoxygenation.
2) Pulojekiti ya oxygen ndiyosavuta kugwira ntchito. Zotsatira zoyezera zitha kupezeka 5-10s mutatha kuziyika muzitsulo zosungunuka.
1, Mulingo Woyezera
Kutentha osiyanasiyana: 1200 ℃ ~ 1750 ℃
Mphamvu ya okosijeni: -200 ~~ + 350mV
Ntchito ya oxygen: 1 ~ 1000ppm
2, Muyezo Wolondola
Kuchulukitsa kwa batire ya oxygen: Ntchito yachitsulo LOX ≥20ppm, cholakwika ndi ± 10% ppm
Zochita zachitsulo LOX <20ppm, cholakwika ndi ± 1.5ppm
Thermocouple kulondola: 1554 ℃, ± 5 ℃
3, Nthawi Yoyankha
Maselo a oxygen 6 ~ 8s
Thermocouple 2 ~ 5s
Nthawi yoyankha yonse 10 ~ 12s
4, Kuchita bwino kwa kuyeza
hyperoxia mtundu ≥95%; hypoxia mtundu ≥95%
