Mhedzisiro yegirafu yekuwedzera pakuita kwe magnesia kabhoni zvidhinha
Mhedzisiro yekuwedzera kwegraphite pakuita kwe magnesia carbon brick
Kazhinji kutaura, chiyero chegraphite chakawedzerwa muMgO-C zvidhinha chinofanira kuva pakati pe15% ne20%. Kana huwandu hwekuwedzera hwakakwirira, kuparara kweMgO-C zvidhinha kunowedzera kuwedzera. Izvi zvinodaro nekuti kana iyo graphite yemukati ichiwedzera, chimiro cheiyo decarburized zvidhinha inova yakaoma. Somugumisiro, kuputika kwe slag per unit volume yezvidhinha inowedzera, zvichiita kuti MgO inyunguduke Kuwanda kwekurasikirwa mu slag kunowedzera kukurumidza; panguva imwechete, sezvo kuwanda kwegraphite kunowedzera, huwandu hwemadota hunounzwa hunowedzerawo, zvichiita kuti kuderedza kusvibiswa kwezvidhinha. Mukuwedzera, kana chiyero che graphite chakawedzerwa chakawandisa, zvakaoma kuumba panguva yekugadzirwa, uye chigadzirwa chacho chiri nyore kuita oxidize panguva yekushandiswa. Mune carbon-bonded refractory material, kana carbon content iri pasi pe10%, iyo inoenderera kabhoni network haigone kuumbwa muchigadzirwa, uye zvakanakira kabhoni hazvigone kushandiswa zvinobudirira; kubva pakuona kwekugadzikana kwekupisa kwekushisa, kuwanda kwegraphite yakawedzerwa iri pasi pe10% ~ 15%, kupisa kwekushisa kwechitinha kunoderedzwa zvakanyanya.
