Isitena se-Chrome corundum sibhekisela kwimveliso ye-corundum refractory equkethe i-Cr2O3. Kwiqondo lokushisa eliphezulu, i-Cr2O3 kunye ne-Al2O3 zenza isisombululo esiqinileyo esiqhubekayo, ngoko ukusebenza kokushisa okuphezulu kweemveliso ze-chrome corundum kungcono kunemveliso ye-corundum ecocekileyo. Isitena somlilo se-Chrome corundum sisetyenziselwa i-petrochemical gasifier kufuneka ibe yi-silicon ephantsi, intsimbi ephantsi, i-alkali ephantsi kunye nococeko oluphezulu, kwaye kufuneka ibe noxinano oluphezulu kunye namandla.Umxholo we-Cr2O3 ukuluhlu lwe-9% ~ 15%
Iimpawu zezitena zeChrome Corundum
- Ukumelana nomlilo okuphezulu,
- Ubunzima obukhulu,
- Ukumelana kakuhle nokunxiba,
- Ukumelana kakuhle nokothuka kwe-thermal,
- I-asidi elungileyo kunye nokumelana ne-alkali,
- Uzinzo oluhle lweekhemikhali.
Inkqubo yokwenziwa kwezitena yeChrome yeCorundum
Isitena se-Chrome corundum sicutshungulwa nge-post-al2o3, yongeza inani elithile le-chromium oxide powder kunye ne-powder ecocekileyo ye-chrome corundum clinker, eyenziwa kwaye itshiswe kwiqondo lokushisa eliphezulu. Umxholo we-chromic oxide kwisitena se-chrome esine-sintered uphantsi ngokubanzi kunolo lwezitena ezidityanisiweyo ze-chrome corundum. Ibhlokhi ye-Chrome corundum iphinda isebenzise indlela yokuphosa udaka, i-alpha Al2O3 powder kunye ne-chrome oxide powder ukuxuba, yongeza iglue kunye ne-organic adhesives eyenziwe ngodaka olunzima, kwangaxeshanye inxalenye ye-chromium corundum clinker, ngokugalela kwi-adobe, ukudubula kwakhona.

Ukusetyenziswa kweZitena zeChrome zeCorundum kwiziko
Izitena ze-Chrome corundum zisetyenziswa ikakhulu kwiindawo ezifuna ukuqhawuka okuphezulu kunye nokumelana nobushushu, njengezitena zikaloliwe ezityibilikayo kwizitena zentsimbi ezityhalela intsimbi, iqonga lokucofa iziko lokuhamba ngemiqadi, kunye nanjengaphakathi kubabhubhisi, kwii-linings ze-carbon soot furnace. kunye neziko lobhedu elinuka ubhedu lokuchopha iqonga leziko lokusila, ukufudumeza umzila kaloliwe wokushushumbisa.
