Njerwa za Magnesia Carbon Zogwira Ntchito Kwambiri Zogwiritsidwa Ntchito M'mafakitale Otentha Kwambiri

Kwa mafakitale opanga zitsulo ndi zitsulo zopanda chitsulo omwe akufuna njira zolimba komanso zotsika mtengo zopewera kukana, zapamwamba komanso zokhalitsa.njerwa za magnesia carbon (MgO-C)Izi ndi zodziwika bwino kwambiri. Zopangidwa ndi magnesia clinker yapamwamba kwambiri, graphite ya flake, ma antioxidants apadera komanso zomangira za resin zamphamvu kwambiri, njerwa zathu za magnesia carbon zimagwira ntchito bwino kwambiri m'malo otentha kwambiri komanso okhala ndi mankhwala oopsa, zomwe zimakhala zinthu zofunika kwambiri pakupanga uvuni zamakono zamafakitale.

Ubwino waukulu wa njerwa zathu za kaboni wa magnesia uli mu mphamvu zawo zapamwamba kwambiri zokanira. Zili ndi mphamvu zambiri zokanira, zimapirira kutentha kosalekeza kuposa 1700°C popanda kusintha kapangidwe kake kapena kuwonongeka. Mosiyana ndi njerwa wamba zokanira, kuphatikiza kwapadera kwa magnesia ndi graphite kumabweretsa kukana kwa dzimbiri kwa slag komanso mphamvu yoletsa kulowa m'madzi. Gawo la graphite limapanga malo osanyowa motsutsana ndi chitsulo chosungunuka ndi slags zosiyanasiyana, zomwe zimaletsa kuwonongeka kwa slags zokhala ndi alkaline ndi iron, zomwe zimachepetsa kwambiri kuwonongeka kwa ng'anjo popanga nthawi yayitali.

Kukana kutentha kwambiri ndi chinthu china chofunikira kwambiri pa zinthu zathu. Ma uvuni a mafakitale nthawi zambiri amakumana ndi kutentha ndi kuzizira mofulumira, zomwe zimapangitsa kuti njerwa zisweke mosavuta. Njerwa zathu za magnesia carbon zimakhala ndi kutentha kochepa komanso kutentha kwambiri, zomwe zimatha kuchepetsa kupsinjika kwa kutentha kwamkati, kupewa kusweka ndi kusweka, ndikusunga umphumphu wokhazikika pakasintha kutentha kwambiri. Pakadali pano, kuwonjezera ma antioxidants amphamvu kwambiri kumawonjezera kwambiri kukana kwa okosijeni kwa zigawo za kaboni, ndikuwonjezera moyo wa njerwazo m'malo otentha kwambiri.

Njerwa zathu za magnesia carbon, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, ndi zabwino kwambiri pazigawo zofunika kwambiri za furnaces zoyambira za oxygen (BOF), furnaces zamagetsi (EAF), ma ladle achitsulo ndi ma tundishes opitilira kuponyedwa. Zilinso zoyenera kwambiri pa furnaces zosungunulira zitsulo zamkuwa, nickel ndi zitsulo zina zopanda ferrous, komanso zida zotentha kwambiri popanga simenti ndi laimu. Kutsimikizira kogwira ntchito m'mafakitale kukuwonetsa kuti njerwa zathu zimatha kuchepetsa nthawi yogwira ntchito yokonza zida ndi pafupifupi 40% poyerekeza ndi zipangizo zachikhalidwe zotsutsa, zomwe zimapangitsa kuti ntchito yokonza ikhale yogwira ntchito bwino komanso kuchepetsa ndalama zogwirira ntchito.

Timatsatira miyezo yokhwima yowongolera khalidwe la kupanga, kupereka njerwa za kaboni za magnesia zamitundu yosiyanasiyana kuti zikwaniritse zofunikira zosiyanasiyana zogwirira ntchito. Kaya ndi zopangira zitsulo zolemera kapena malo apadera osungunula zitsulo zopanda chitsulo, zinthu zathu zimapereka magwiridwe antchito okhazikika, kulimba kwambiri komanso magwiridwe antchito odabwitsa. Sankhani njerwa zathu zapamwamba za kaboni za magnesia kuti mukweze makina anu oyikamo uvuni ndikuwonjezera phindu lanu popanga mafakitale.
