Njerwa za kaboni ya Magnesia ndi mtundu wa kaboni wosayaka womwe umapangidwa ndi magnesium oxide ya alkaline oxide yokhala ndi malo osungunuka kwambiri (2800℃), ndi zinthu za kaboni zomwe zimakhala ndi malo osungunuka kwambiri omwe ndi ovuta kuwola ndi slag ya uvuni ngati zopangira, ndipo zimawonjezeredwa mitundu yonse ya zowonjezera zopanda ma oxides ndi carbon binding agent. Njerwa za kaboni ya Magnesia zili ndi mawonekedwe otsika a porosity, kukana kukokoloka kwa slag, kukana kutentha kwambiri komanso mphamvu yapamwamba kwambiri yotentha. Monga mtundu wa compository wosakanikirana, njerwa za kaboni ya Magnesia zimagwiritsa ntchito slag corrosion yamphamvu ya magnesia komanso kutentha kwambiri komanso kufalikira kochepa kwa kaboni bwino, zimatha kubweza vuto lalikulu la spalling resistance ya magnesia.
Katundu wa Njerwa za Magnesia Carbon
- Katundu wabwino wokana kutentha kwambiri,
- Kukana kutentha bwino,
- Kukhazikika kwa kutentha kwabwino,
- Kuyendetsa bwino kutentha,
- Kutentha kochepa kwambiri,
- Kukana kukokoloka kwa nthaka mwamphamvu.
Kuphatikizika kwa Njerwa za Magnesia Carbon
Njerwa za Magnesia carbon zomwe zili m'gulu la zigawo zikuluzikulu ndi magnesium oxide ndi carbon, zomwe magnesium oxide ili ndi 60 ~ 90% ndipo carbon ili ndi 10 ~ 40%. Zipangizo zamtunduwu zimapangidwa ndi tinthu ta magnesia toyera kwambiri, carbon, tar, phula kapena resin monga zopangira zophikira pogwiritsa ntchito kutentha kwambiri. Chifukwa chake, njerwa za magnesite carbon zimakhala ndi mphamvu zotsutsana ndi dzimbiri, kukana kutentha, kutentha, ndi zina zotero.
Njira Yopangira Njerwa za Magnesia Carbon
Malinga ndi njira zosakaniza zozizira, phula lomangira limalimba ndipo limapeza mphamvu yofunikira, motero limapanga isotropous vitric carbon. Njerwa za Magnesia carbon zimapangidwa ndi phula lomangira, lomwe limakhala ndi kutentha kwambiri chifukwa chopanga kapangidwe ka anisotropic graphitization coke mu njira ya pitch carbonation. Mtundu uwu wa kaboni suwonetsa kutentha komwe kungachotsere kuchuluka kwa kupsinjika munthawi yowotcha kapena kugwira ntchito.

Kugwiritsa Ntchito Njerwa za Magnesia Carbon
Njerwa za Magnesia carbon zimagwiritsidwa ntchito makamaka popanga zophimba za converter, ng'anjo yamagetsi-arc ndi ng'anjo yamagetsi ya arc yamagetsi ya direct current, mzere wa slag wa ndevu yachitsulo ndi malo ena. Ndipo zingagwiritsidwenso ntchito popanga ng'anjo ya okosijeni, mzere wa slag wa ng'anjo yamagetsi ndi malo otentha a ng'anjo yamagetsi.
Wopanga Njerwa za Magnesia Carbon kuchokera ku RS Refractory Factory
Fakitale ya RS yokana njerwa monga imodzi mwa opanga njerwa za carbon za magnesite mu uvuni, imatha kupereka njerwa zabwino za carbon za magnesia kwa makasitomala ndi mainjiniya aluso, ukadaulo wapamwamba wopanga komanso ntchito yabwino musanagulitse komanso mutagulitsa. Fakitale ya RS yokana yakhala ikugwira ntchito yokonza njerwa za carbon za magnesite kwa zaka zoposa 20. Ngati mukufuna njerwa za carbon za magnesia, titumizireni kwaulere, malonda athu adzakuyankhani nthawi yoyamba.
