Izitini ezine-chrome ephezulu zenziwe nge-magnesia (MgO) kanye ne-chromium oxide (Cr2O3) njengesithako esiyinhloko, i-periclase kanye ne-spinel njengezingxenye eziyinhloko zamaminerali zemikhiqizo ephikisayo. Ukuqina kwezitini okunjalo okuphezulu, amandla okushisa aphezulu, ukumelana nokumelana nokuguguleka kwe-slag okuyisisekelo, ukuzinza okuhle kakhulu kokushisa, i-asidi slag nakho kunokuvumelana nezimo. Izinto eziyinhloko zokukhiqiza izitini ezine-chrome ephezulu yi-magnesia ehlanganisiwe kanye ne-chromite. Ukuze izinto zokusetshenziswa ze-magnesia ezihlanzekile zibe phezulu ngangokunokwenzeka, izidingo zokwakheka kwamakhemikhali kwe-chromite yilezi: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
Izakhiwo Zezitini Ezine-Chrome Eningi
- Amandla aphezulu,
- Ukumelana nokugqwala,
- Ukumelana nokuguguleka komhlabathi,
- Ukumelana okuhle kakhulu kwe-slag,
- Ukuqina okuhle kokushaqeka kokushisa.
Ukwakheka Kwezitini Ezine-Chrome Eningi
Izitini ze-chrome eziphakeme kakhulu zakhiwe kakhulu yi-Cr2O3, i-monoclinic zirconia kanye ne-alumina powder. Ngakho-ke, ukusebenza kwe-chromebricks ephezulu kuhlobene kakhulu nokusebenza kwalezi zinto. Izitini ze-chrome eziphezulu ziqukethe i-chromium hemitrioxide engu-30%, kanti izitini ze-chrome eziphakeme zibonakala ngokumelana ne-acid kanye ne-alkali slags, futhi zisetshenziswa kakhulu kungqimba lokuhlukaniswa, kanye nezitofu zokuncibilikisa ezingenayo i-ferrous, njll.
Inqubo Yokukhiqiza Izitini Eziphezulu Ze-Chrome
Izitini eziqinile ze-chrome zenziwe nge-magnesium esezingeni eliphezulu kanye ne-chrome ore fine charge mix. Ngokwezidingo ezahlukene, lungisa okuqukethwe yi-Cr2O3, Ukuqina kokushisa komkhiqizo kanye nokusebenza kokushisa okuphezulu kuyanelisa. Izitini eziqinile ze-chrome zisetshenziswa kabanzi kuhhavini wesamente kanye nesithando sensimbi esingenalo i-ferrous njll.

Ukusetshenziswa Kwezitini Eziphezulu Ze-Chrome
Izitini ezine-chrome ephezulu zingasetshenziswa embonini yensimbi, embonini yezinto zokwakha, nakwezinye izithando zokuncibilikisa ezingenayo i-ferrous, njll. futhi zingasetshenziswa ukuqondisa indawo yokushisisa yenqubo entsha yokucubungula okomile kwama-oven esimende kanye nezithando zethangi lengilazi njengezi-checker kanye nezinye izithando zezimboni.
Umkhiqizi Wezitini Eziphezulu Ze-Chrome ovela ku-RS Refractory Factory
I-RS Refractory Factory ingumhlinzeki wezitini ochwepheshe onama-chrome amaningi owasungulwa ekuqaleni kwawo-90s wekhulu lama-20. I-RS Refractory Factory ibilokhu igxile kuma-block ane-chrome amaningi iminyaka engaphezu kwengu-20. Izinzuzo ze-RS Refractory Factory yilezi ezilandelayo:
- Indawo efanelekile,
- Izikali ezinkulu,
- Idumela elihle,
- Intengo evumayo,
- Isevisi yobungcweti,
- Ukulethwa okusheshayo.
