Isitini se-Chrome corundum sibhekisela kumkhiqizo ophikisayo we-corundum oqukethe i-Cr2O3. Uma izinga lokushisa liphezulu, i-Cr2O3 ne-Al2O3 zakha isisombululo esiqinile esiqhubekayo, ngakho-ke ukusebenza kwezinga lokushisa eliphezulu kwemikhiqizo ye-chrome corundum kungcono kunokwemikhiqizo ye-corundum emsulwa. Isitini somlilo se-Chrome corundum sisetshenziswa ku-gasifier ye-petrochemical kufanele sibe yi-silicon ephansi, insimbi ephansi, i-alkali ephansi kanye nobumsulwa obuphezulu, futhi kufanele sibe nobukhulu obuphezulu namandla. Okuqukethwe kwe-Cr2O3 kuphakathi kuka-9% ~ 15%
Izici Zezitini Ze-Chrome Corundum
- Ukumelana nomlilo okuphezulu,
- Ukuqina okukhulu,
- Ukumelana okuhle nokuguguleka,
- Ukumelana okuhle nokushaqeka kokushisa,
- Ukumelana okuhle kwe-asidi ne-alkali,
- Ukuqina okuhle kwamakhemikhali.
Inqubo Yokukhiqiza Izitini ze-Chrome Corundum
Isitini se-Chrome corundum sicutshungulwa nge-post-al2o3, kufakwe inani elithile le-chromium oxide powder kanye ne-fine powder ye-chrome corundum clinker, ezakhiwe futhi zishiswe ekushiseni okuphezulu. Okuqukethwe kwe-chromic oxide esitini se-chrome esicwebezelayo ngokuvamile kuphansi kunokwesitini se-chrome corundum esihlanganisiwe. I-Chrome corundum block isebenzisa nendlela yokulungiselela ukuthungwa kodaka, i-alpha Al2O3 powder kanye ne-chrome oxide powder mixing, engeza i-glue kanye ne-organic adhesives ezenziwe ngodaka olujiyile, ngesikhathi esifanayo ingxenye ye-chromium corundum clinker, ngokufaka i-grout ku-adobe, bese kuqhuma futhi.

Ukusetshenziswa Kwesitini Se-Chrome Corundum Sesithando Somlilo
Izitini ze-Chrome corundum zisetshenziswa kakhulu ezindaweni ezidinga ukuguguleka okuphezulu kanye nokumelana nokushisa, njengezitini zesitimela ezishelelayo ezitsheni zensimbi ezisebenzisa insimbi, izitofu zokuhamba zesitayela seplatifomu yokuthepha, kanye nangaphakathi lababhubhisi, Ezingxeni zesithando se-carbon soot kanye nesithando se-copper smelling esisekelweni sesithando sokugaya esigoqayo, ukuphinda kufudumale isithando se-skid esisetshenziswayo.
