Chrome corundum zvidhinha inoreva corundum refractory chigadzirwa chine Cr2O3. Pakupisa kwepamusoro, Cr2O3 uye Al2O3 inoumba inoenderera yakasimba mhinduro, saka tembiricha yepamusoro yezvigadzirwa zve chrome 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 Features
- High moto resistance,
- Kusimba kukuru,
- Kupfeka kwakanaka kuramba,
- Good thermal shock resistance,
- Asidhi yakanaka uye alkali kuramba,
- Kugadzikana kwakanaka kwemakemikari.
Chrome Corundum Brick Manufacturing Process
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. Zvirimo zvechromic oxide mune sintered chrome zvidhinha zvinowanzo kudzika pane izvo zvakasanganiswa 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 imwe chete chikamu chechromium corundum clinker, negrouting muadobe, kupfura zvakare.

Kushandiswa kweChrome Corundum Brick yeFirnace
Chrome corundum zvidhinha inonyanya kushandiswa munzvimbo dzinoda abrasion yakakwira uye tembiricha kuramba, senge kusvetuka njanji zvidhinha musimbi pusher metallurgical furnaces, tapping papuratifomu dhizaini inofamba danda mavira, uye zvakare semukati mevaparadzi, Mumicheka yekabhoni soot choto. uye choto chinonhuhwira chemhangura yekutapa chikuva chemoto cheguyo chinopisa, chinopisa moto wefurnace skid rail.
