Izitena ezine-chrome ephezulu zenziwe nge-magnesia (MgO) kunye ne-chromium oxide (Cr2O3) njengesithako esiphambili, i-periclase kunye ne-spinel njengezona zinto ziphambili zezimbiwa zeemveliso ezichaseneyo. Ezi zitena zichaseneyo, amandla aphezulu obushushu, ukumelana nokukhukuliseka okusisiseko kwe-slag, uzinzo oluhle kakhulu lobushushu, i-asidi ye-slag ikwanokuguquguquka. Izinto eziphambili zokwenza izitena ezine-chrome ephezulu yi-sintered magnesia kunye ne-chromite. Izinto eziluhlaza ze-magnesia ezicocekileyo ukuze zibe phezulu kangangoko kunokwenzeka, iimfuno zekhemikhali ye-chromite zezi: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
Iipropati zezitena zeChrome eziphezulu
- Amandla aphezulu,
- Ukumelana nokugqwala,
- Ukumelana nokukhukuliseka komhlaba,
- Ukumelana ne-slag okugqwesileyo,
- Uzinzo oluhle lobushushu.
Ukwakhiwa kwezitena ze-Chrome eziphezulu
Izitena ezine-chrome eninzi ziquka i-Cr2O3, i-monoclinic zirconia kunye ne-alumina powder. Ke ngoko, ukusebenza kwe-chromebricks ephezulu kunxulumene kakhulu nokusebenza kwezi zinto. Izitena ezine-chrome ephezulu ziqulethe i-chromium hemitrioxide 30%, kwaye izitena ezine-chrome ephezulu zinokumelana ne-acid kunye ne-alkali slags, kwaye zisetyenziswa kakhulu kumaleko wokuzihlukanisa, kunye nee-nonferrous smelting furnaces, njl.njl.
Inkqubo Yokuvelisa Izitena Eziphezulu ZeChrome
Izitena ezirhabaxa ze-chrome eziphezulu zenziwe ngomxube we-magnesite okumgangatho ophezulu kunye nomxube we-chrome ore fine charge. Ngokweemfuno ezahlukeneyo, lungisa umxholo we-Cr2O3, Uzinzo lobushushu bemveliso kunye nokusebenza kobushushu obuphezulu kuyanelisa. Izitena ze-chrome eziphezulu zisetyenziswa kakhulu kwi-oven yesamente kunye ne-oven ye-metallurgical engeyiyo i-ferrous njl.

Ukusetyenziswa kwezitena ze-Chrome eziphezulu
Izitena ezinekhromu ephezulu zingasetyenziswa kushishino lwesinyithi, kushishino lwezinto zokwakha, nakwezinye iziko lokunyibilikisa elingenayo i-ferrous, njl. kwaye zingasetyenziswa ukulungelelanisa indawo yokusila yenkqubo entsha yokomisa ii-kilns zesamente kunye neziko zetanki yeglasi njengezitsheki kunye nezinye iziko zoshishino.
Umenzi wezitena ze-Chrome eziphezulu ovela kwi-RS Refractory Factory
I-RS Refractory Factory yinkampani yobungcali yokubonelela ngezitena ezikhazimlayo ezine-chrome ephezulu eyasekwa kwiminyaka yoo-90 kwinkulungwane yama-20. I-RS Refractory Factory ibisoloko igxile kwi-chrome block ephezulu kangangeminyaka engaphezu kwama-20. Iingenelo ze-RS Refractory Factory zezi zilandelayo:
- Indawo efanelekileyo,
- Izikali ezinkulu,
- Udumo oluhle,
- Ixabiso elilungileyo,
- Inkonzo yobungcali,
- Ukuhanjiswa ngokukhawuleza.
