Isitini se-Chrome corundum sisho umkhiqizo we-corundum refractory oqukethe i-Cr2O3. Emazingeni okushisa aphezulu, i-Cr2O3 ne-Al2O3 bakha isisombululo esiqinile esiqhubekayo, ngakho-ke ukusebenza kwezinga lokushisa okuphezulu kwemikhiqizo ye-chrome corundum kungcono kunokwemikhiqizo ye-corundum ehlanzekile. Isitini somlilo se-Chrome corundum sisetshenziswa ku-petrochemical gasifier kufanele sibe i-silicon ephansi, insimbi ephansi, i-alkali ephansi nokuhlanzeka okuphezulu, futhi kufanele sibe nokuminyana okuphezulu namandla.Okuqukethwe kwe-Cr2O3 kububanzi obungu-9%~15%
Izici zezitini ze-Chrome Corundum
- Ukumelana nomlilo okuphezulu,
- Ubunzima obukhulu,
- Ukumelana nokugqoka okuhle,
- Ukumelana nokushaqeka okuhle kokushisa,
- I-asidi enhle ne-alkali ukumelana,
- Ukuzinza okuhle kwamakhemikhali.
Inqubo Yokukhiqiza Izitini ze-Chrome Corundum
Isitini se-Chrome corundum sicutshungulwa nge-post-al2o3, sinezela inani elithile le-chromium oxide powder kanye ne-powder enhle ye-chrome corundum clinker, eyakhiwe futhi ishiswe ekushiseni okuphezulu. Okuqukethwe kwe-chromic oxide kusitini se-chrome esifakiwe ngokuvamile kuphansi kunalokho kwesitini se-chrome corundum esihlanganisiwe. I-Chrome corundum block iphinde isebenzise indlela yokulungiselela udaka, i-alpha Al2O3 powder kanye ne-chrome oxide powder mixing, engeza iglue nezinamatheliso eziphilayo ezenziwe ngodaka oluwugqinsi, ngesikhathi esifanayo ingxenye ye-chromium corundum clinker, ngokugxumela ku-adobe, ukudubula futhi.

Ukusetshenziswa kwe-Chrome Corundum Brick yesithando somlilo
Isitini se-Chrome corundum sisetshenziswa kakhulu ezindaweni ezidinga ukuhuzuka okuphezulu kanye nokumelana nezinga lokushisa, njengezitini zesitimela ezitshuzayo ezifundeni zensimbi ze-steel pusher metallurgical, isitayela seplatifomu ethephayo ukuhamba kwezibani zomlilo, kanye nanjengaphakathi lababhubhisi, Emigqeni yesithando somlilo we-carbon soot. kanye neplathifomu yokuthepha yesithando somlilo se-copper yesithando somlilo esiginqikayo, esifudumeza kabusha i-skid rail yesithando somlilo.
