Izitena eziphezulu ze-chrome zenziwe nge-magnesia (MgO) kunye ne-chromium oxide (i-Cr2O3) njengesithako esiphambili, i-periclase kunye ne-spinel njengezona zinto zibalulekileyo zamaminerali kwiimveliso eziphikisayo. Ezo zitena zokuchasa okuphezulu, ukomelela okuphezulu kobushushu, ukuxhathisa kwisiseko sokhukuliseko lwe-slag, uzinzo oluhle kakhulu lwe-thermal, i-acidic slag nayo inokuguquguquka okuthile. Eyona mathiriyeli ikrwada yokwenza izitena eziphezulu ze-chrome refractory yi-sintered magnesia kunye nechromite. Ubumsulwa magnesia ekrwada ukuba ibe phezulu kangangoko kunokwenzeka, iimfuno ukwakheka imichiza chromite yile: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
Iipropati zezitena eziphezulu zeChrome
- Amandla aphezulu,
- Ukuchasa ukubola,
- Ukumelana nokhukuliseko,
- Ukuchasana kakuhle kwe-slag,
- Uzinzo oluhle lokutshatyalaliswa kwe-thermal.
Ukuqulunqwa kwezitena eziphezulu zeChrome
Izitena eziphezulu ze-chrome zibandakanya ikakhulu i-Cr2O3, i-monoclinic zirconia kunye ne-alumina powder. Ngoko ke, ukusebenza kwe-chromebricks ephezulu kuhambelana ngokusondeleyo nokusebenza kwezi zinto. Izitena eziphezulu zomlilo we-chrome ziqulethe i-chromium hemitrioxide 30%, kunye nezitena eziphezulu ze-chrome zibonakaliswe nge-asidi kunye ne-alkali slags ukumelana, kwaye zisetyenziselwa ikakhulu kwi-layer yodwa, kunye neziko zokunyibilikisa ezingenayo i-nonferrous, njl.
Inkqubo yokuVelisa izitena eziPhezulu zeChrome
Isitena esine-chrome esiphezulu se-refractory senziwe ngomgangatho ophezulu we-magnesite kunye nomxube we-chrome ore fine charge charged. Ngokweemfuno ezahlukeneyo, lungisa umxholo we-Cr2O3, Uzinzo lwe-thermal yemveliso kunye nokusebenza kobushushu obuphezulu kuyanelisa. Izitena eziphezulu ze-chrome zisetyenziswa ngokubanzi kwi-sement kiln kunye ne-nonferrous metallurgical furnace njl.

Ukusetyenziswa kwezitena eziphezulu zeChrome
Izitena eziphezulu ze-chrome zingasetyenziswa kushishino lwesinyithi, ishishini loyilo lwemathiriyeli, kunye nezinye iziko lokunyibilikisa elingenawo i-ferrous, njl. njl amanye amaziko oshishino.
Umvelisi wezitena eziPhezulu zeChrome ukusuka kwi-RS Refractory Factory
Umzi-mveliso we-RS refractory ngumboneleli ochwephesha wezitena owenziwe ngechrome ephezulu owasekwa ekuqaleni kweminyaka yama-90 yenkulungwane yamashumi amabini. Umzi-mveliso we-RS refractory ukhethekileyo kwibhloko ye-chrome ephezulu ngaphezu kweminyaka engama-20. Izinto eziluncedo kwi-RS Refractory Factory zezi zilandelayo:
- Indawo elungileyo,
- Imibala emikhulu,
- Isidima esihle,
- Ixabiso elincomekayo,
- Inkonzo yobungcali,
- Ukuhanjiswa ngokukhawuleza.
