Njerwa ya Alumina Ccarbon ndi mtundu wa zinthu zosakanikirana ndi kaboni zomwe zimapangidwa ndi alumina ndi zinthu za kaboni, nthawi zina zosakanikirana ndi silicon carbide, silicon yachitsulo ndi zomangira zina zachilengedwe, monga utomoni. Njerwa za alumina carbon fire fire flakes zimakhala ndi njerwa za aluminiyamu carbonaceous slide, njerwa za cast nozzle, njerwa za aluminiyamu carbon zosagonjetseka ndi fire fire aluminium carbon stone. Mbali za njerwa za alumina carbon refractory ndi kukana dzimbiri, kukhazikika bwino kwa kutentha, mphamvu yayikulu komanso kutentha kwambiri.
Njira Yopangira Njerwa ya Alumina Carbon
Njerwa za kaboni za Alumina zimapangidwa pogwiritsa ntchito bauxite clinker yapadera, corundum, graphite ndi mid alumina ngati zopangira zazikulu, kuphatikiza mitundu ingapo ya zowonjezera ufa wabwino kwambiri. Njira yopangira njerwa za alumina kaboni yokana ndi kuwonjezera Aluminium oxide, carbonaceous, silicon powder ndi zinthu zina zochepa zopangira ku zopangira, kenako gwiritsani ntchito phula, chomangira, resin kapena zosakaniza, kusakaniza, kukanikiza, pafupifupi 1300 ℃ kusungunula mlengalenga.
Makhalidwe a Njerwa ya Alumina Carbon
- kukana dzimbiri mwamphamvu,
- kukhazikika bwino kwa kutentha,
- mphamvu zambiri,
- kutentha kwakukulu.
Gulu la njerwa ya kaboni ya Alumina
Njerwa za kaboni za Alumina zitha kugawidwa m'magulu awiri, njerwa za kaboni za magnesia alumina ndi njerwa za kaboni za alumina magnesia.
Njerwa ya kaboni ya Magnesia alumina, yokhala ndi magnesite, corundum, spinel ndi graphite yapamwamba kwambiri ngati zopangira, yolumikizidwa ndi utomoni, imadziwika ndi kukana bwino kwa slag.
Njerwa za kaboni za Alumina magnesia, zokhala ndi bauxite yapamwamba kwambiri, corundum, spinel, magnesite yoyera kwambiri ndi graphite ngati zopangira, zolumikizidwa ndi utomoni, zimadziwika ndi kukokoloka ndi dzimbiri, kukana kuphulika.

Kugwiritsa Ntchito Njerwa ya Alumina Carbon
Njerwa ya kaboni ya Alumina imagwiritsidwa ntchito popangira khoma la bosh, stack ndi kuziziritsa khoma la ng'anjo yophulika. Njerwa ya kaboni ya Magnesia alumina imagwiritsidwa ntchito makamaka popangira mzere wa slag wapamwamba ndi wotsika. Njerwa ya kaboni ya Alumina magnesia imagwiritsidwa ntchito makamaka popangira ladle slag pansi ndi pansi.
