Chrome corundum zvidhinha inoreva corundum refractory chigadzirwa chine Cr2O3. Pakupisa kwepamusoro, Cr2O3 uye Al2O3 inoumba inoenderera yakasimba mhinduro, saka tembiricha yepamusoro yezvigadzirwa zvechrome corundum iri nani pane iyo yakachena corundum zvigadzirwa. Chrome corundum moto zvidhinha inoshandiswa mu petrochemical gasifier inofanira kuva yakaderera silicon, yakaderera simbi, yakaderera alkali uye yakakwirira kuchena, uye inofanira kuva nepamusoro density uye simba.Zviri muCr2O3 zviri muhuwandu hwe9% ~ 15%
Chrome corundum brick inogadziriswa ne-post-al2o3, ichiwedzera imwe chromium oxide poda uye poda yakanaka ye chrome corundum clinker, iyo inoumbwa uye inopisa pakupisa kukuru. Zviri mukati chromic oxide mune sintered chrome zvidhinha kazhinji yakaderera pane iyo yakasanganiswa cast chrome corundum zvidhinha. Chrome corundum block inoshandisawo madhaka ekukanda nzira yekugadzirira, iyo alpha Al2O3 hupfu uye chrome oxide poda kusanganisa, wedzera guruu uye organic adhesives akagadzirwa kubva mumatope gobvu, panguva imwechete chikamu chechromium corundum clinker, negrouting muadobe, kupfura zvakare.
