.Isitini se-Magnesia-chromeinto eyisisekelo ephikisayo ene-magnesium oxide (MgO) ne-chromium trioxide (Cr2O3) njengezingxenye eziyinhloko. Inezici ezinhle kakhulu ezifana ne-high refractoriness, ukumelana nokushaqeka okushisayo, ukumelana ne-slag nokumelana nokuguguleka. Izingxenye zayo eziyinhloko zamaminerali yi-periclase ne-spinel. Lezi zici zenza izitini ze-magnesia-chrome zisebenze kahle ezindaweni zokushisa okuphezulu futhi zifanele imishini ehlukahlukene yezimboni ezisezingeni eliphezulu. .
Izithako kanye nenqubo yokukhiqiza.
Izinto zokusetshenziswa eziyinhloko zezitini ze-magnesia-chrome ziyi-sintered magnesia ne-chromite. I-Magnesia inesidingo esiphezulu sokuhlanzeka, kuyilapho ukwakheka kwamakhemikhali e-chromite kuvame ukuba okuqukethwe kwe-Cr2O3 phakathi kuka-30% no-45%, futhi okuqukethwe kwe-CaO akudluli u-1.0% kuya ku-1.5%. Inqubo yokukhiqiza ihlanganisa indlela yokubopha okuqondile kanye nendlela yokungadubuli. Ukubopha okuqondile izitini ze-magnesia-chrome zisebenzisa izinto eziluhlaza ezihlanzekile futhi zishiswa ekushiseni okuphezulu ukuze zenze isigaba esiphezulu sokushisa okuhlangene okuqondile kwe-periclase ne-spinel, okuthuthukisa kakhulu amandla okushisa aphezulu kanye nokumelana ne-slag. .
Izici zokusebenza
.I-refractory ephezulu:I-refractoriness ngokuvamile ingaphezu kuka-2000 ° C, futhi ingagcina ukuqina okuhle kwesakhiwo ezingeni lokushisa eliphezulu.
Ukumelana nokushaqeka okushisayo:Ngenxa ye-coefficient ephansi yokunwetshwa kwe-thermal, ingakwazi ukuzivumelanisa nezinguquko ezinkulu kuzinga lokushisa.
Ukumelana ne-slag:Inokumelana okuqinile ne-alkaline slag kanye ne-acidic slag ethile, futhi ifaneleka kakhulu izindawo ezivezwe ku-slag ephezulu yokushisa.
Ukumelana nokugqwala:Inokubekezelela okunamandla ukuguguleka kwe-acid-base nokuguguleka kwegesi.
.Ukuzinza kwamakhemikhali:Isixazululo esiqinile esakhiwe i-magnesium oxide ne-chromium oxide ezitini ze-magnesia-chrome sinokuzinza okuphezulu kwamakhemikhali.
Izinkambu zohlelo lokusebenza
Izitini ze-Magnesium-chrome zisetshenziswa kabanzi emkhakheni we-metallurgical, imboni kasimende kanye nemboni yengilazi:
Imboni ye-Metallurgical:esetshenziselwa ulwelwesi lwemishini yokushisa ephezulu efana neziguquli, izithando zomlilo zikagesi, izithando zomlilo ezivulekile, ama-ladle kanye neziqhumane eziqhumayo embonini yensimbi, efanelekile ikakhulukazi endaweni yokuphatha i-alkaline slag ephezulu.
.Imboni kasimende:esetshenziselwa indawo yokudubula kanye nendawo yoguquko yezikloni zikasimende ezijikelezayo ukumelana nokuguguleka kwezinga lokushisa eliphezulu kanye nomkhathi we-alkaline.
Imboni yengilazi:esetshenziselwa ukuvuselela kanye nezingxenye zesakhiwo esiphezulu ezithandweni zokuncibilikisa ingilazi, futhi ingamelana nokuguguleka komkhathi wokushisa okuphezulu kanye noketshezi lwengilazi ye-alkaline.
