Isitena se-Chrome corundum sibhekisa kwimveliso enganyangekiyo ye-corundum equlethe i-Cr2O3. Kubushushu obuphezulu, i-Cr2O3 kunye ne-Al2O3 zenza isisombululo esiqinileyo esiqhubekayo, ngoko ke ukusebenza kobushushu obuphezulu kweemveliso ze-chrome corundum kungcono kunokweemveliso ze-corundum ezicocekileyo. Isitena somlilo se-Chrome corundum sisetyenziswa kwi-gasifier ye-petrochemical kufuneka sibe yi-silicon ephantsi, i-iron ephantsi, i-alkali ephantsi kunye nobunyulu obuphezulu, kwaye kufuneka sibe noxinano oluphezulu kunye namandla. Umxholo we-Cr2O3 ukwi-9% ~ 15%
Iimpawu zeCrike yeCorundum yeChrome
- Ukumelana nomlilo okuphezulu,
- Ubunzima obukhulu,
- Ukumelana nokuguguleka okuhle,
- Ukumelana kakuhle nobushushu,
- Ukumelana okuhle kwe-asidi kunye ne-alkali,
- Uzinzo oluhle lweekhemikhali.
Inkqubo yokwenziwa kwezitena zeChrome Corundum
Isitena se-Chrome corundum sicutshungulwa nge-post-al2o3, songeza inani elithile le-chromium oxide powder kunye ne-fine powder ye-chrome corundum clinker, ezithi zenziwe kwaye zitshiswe kubushushu obuphezulu. Umxholo we-chromic oxide kwisitena se-chrome esitshisiweyo udla ngokuba sezantsi kunowesitena se-chrome corundum esitshisiweyo. I-Chrome corundum block ikwasebenzisa indlela yokulungiselela i-mud casting, i-alpha Al2O3 powder kunye ne-chrome oxide powder mixing, yongeza iglu kunye ne-organic adhesives ezenziwe ngodaka olukhulu, ngaxeshanye inxalenye ye-chromium corundum clinker, ngokuyi-grouting ibe yi-adobe, itshaye kwakhona.

Ukusetyenziswa kweSitena seCorundum seChrome kwiSitovu
Izitena ze-Chrome corundum zisetyenziswa kakhulu kwiindawo ezifuna ukurhawuzelelwa okuphezulu kunye nokumelana nobushushu, njengezitena ze-gliding rail kwii-oven ze-metallurgical pusher zentsimbi, ii-ovens ze-walking beam style ze-tapping platform, kunye nangaphakathi kwi-destructors, Kwi-linings ye-carbon soot furnace kunye ne-copper smeling furnace tapping platform ye-rolling mill furnace, i-reheating furnace skid rail.
