Chromic corundum

Chrome corundum:
Iyo huru yemaminerari inoumbwa ndeye α-Al2O3-Cr2O3 yakasimba mhinduro.
Iyo yechipiri mineral inoumbwa idiki diki yekomboni spinel (kana isina komputa spinel), uye zviri mukati chromium oxide 1% ~ 30%.
Kune marudzi maviri eakasanganiswa cast chrome corundum zvidhinha uye sintered chrome corundum zvidhinha.
Kazhinji, chrome corundum zvidhinha zvinoreva sintered chrome corundum zvidhinha.Kushandisa α-Al2O3 seyakagadzirwa, kuwedzera huwandu hwakakodzera hwechromic oxide poda uye chromic corundum clinker poda, kuumba, kupisa pakupisa kwakanyanya.Iyo chromium oxide yemukati ye sintered chrome rigid zvidhinha kazhinji yakadzikira pane iyo yakasanganiswa cast chrome corundum zvidhinha.Inogonawo kugadzirwa nenzira yekukanda madhaka.Iyo α-Al2O3 hupfu uye chromium oxide hupfu zvakasanganiswa zvakaenzana, uye degumming agent uye organic binder zvinowedzerwa kuita dope gobvu.Panguva imwecheteyo, imwe chromium corundum clinker inowedzerwa, uye brick billet inogadzirwa negrouting nzira uye inobva yadzingwa.Iyo inogona kushandiswa seyakagadzika yegirazi honi, chidhinha chekuvharira chegirazi chinoyerera gomba uye kutsigirwa kwesimbi inopisa pretreatment mudziyo, tsvina yekupisa, marasha emvura slurry pressure gasifier, nezvimwe.
