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 kuneemveliso ezicocekileyo ze-corundum. 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 noxinzelelo oluphezulu kunye namandla.Umxholo we-Cr2O3 ukuluhlu lwe-9% ~ 15%
Isitena se-Chrome corundum sicutshungulwa nge-post-al2o3, yongeza inani elithile le-chromium oxide powder kunye nomgubo ococekileyo we-chrome corundum clinker, owenziwe kwaye utshiswe kwiqondo lokushisa eliphezulu. Umxholo we-chromic oxide kwizitena ze-chrome esintered 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 ukuxuba umgubo, yongeza iglue kunye ne-organic adhesives ezenziwe ngodaka olunzima, kwangaxeshanye inxalenye ye-chromium corundum clinker, ngokugalela kwi-adobe, ukudubula kwakhona.

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, kwiilayini zesithando somlilo sekhabhoni. kunye neqonga lobhedu elinuka ubhedu lokusila kwiziko lokusila, ukufudumeza umzila kaloliwe wokushushumbisa.
