...Isitena seMagnesia-chromeyinto esisiseko ephikisayo kunye ne-magnesium oxide (MgO) kunye ne-chromium trioxide (Cr2O3) njengezona nxalenye eziphambili. Ineempawu ezigqwesileyo ezifana nokuchasa okuphezulu, ukuxhathisa ukothuka kwe-thermal, ukumelana ne-slag kunye nokumelana nokukhukuliseka. Amacandelo ayo amaminerali aphambili yi-periclase kunye ne-spinel. Ezi mpawu zenza izitena ze-magnesia-chrome ziqhube kakuhle kwiindawo eziphakamileyo zokushisa kwaye zifanelekile kwizixhobo ezahlukeneyo zoshishino oluphezulu. ...
Izithako kunye nenkqubo yokuvelisa...
Izinto eziphambili zezinto ezisetyenziswayo zezitena ze-magnesia-chrome ziyi-sintered magnesia kunye ne-chromite. I-Magnesia inemfuno ephezulu yokucoceka, ngelixa ukubunjwa kweekhemikhali ze-chromite ngokuqhelekileyo kumxholo we-Cr2O3 phakathi kwe-30% kunye ne-45%, kwaye umxholo we-CaO awudluli kwi-1.0% ukuya kwi-1.5%. Inkqubo yokuvelisa ibandakanya indlela yokudibanisa ngokuthe ngqo kunye nendlela yokungaqhubi. Ukudibanisa ngokuthe ngqo izitena ze-magnesia-chrome zisebenzisa izinto ezihlambulukileyo eziphezulu kwaye zitshiswe kwiqondo lokushisa eliphezulu ukuze zenze i-high-temperature ye-high-temperature yokubambisana ngokuthe ngqo kwe-periclase kunye ne-spinel, ephucula kakhulu amandla okushisa aphezulu kunye nokumelana ne-slag. ...
Iimpawu zokusebenza
...High refractory:I-refractoriness ivame ukuba ngaphezu kwe-2000 ° C, kwaye inokugcina uzinzo oluhle lwesakhiwo kwiqondo lokushisa eliphezulu.
Ukumelana nokothuka kweThermal:Ngenxa ye-coefficient yokwandisa i-thermal ephantsi, iyakwazi ukuziqhelanisa nokutshintsha okukhulu kwiqondo lokushisa.
Ukumelana ne-Slag:Inokumelana okuqinileyo ne-alkaline slag kunye ne-acidic slag ethile, kwaye ifanelekile ngokukodwa kwiindawo ezivezwe kwi-slag ephezulu yokushisa.
Ukumelana nokuMhlwa:Inonyamezelo oluqinileyo kukhukuliseko olutshintshanayo lwe-asidi kunye nokhukuliseko lwegesi.
...Uzinzo kwiChemical:Isisombululo esiqinileyo esenziwe yi-magnesium oxide kunye ne-chromium oxide kwizitena ze-magnesia-chrome sinokuzinza okuphezulu kweekhemikhali.
Iinkalo zesicelo
Izitena ze-Magnesium-chrome zisetyenziswa ngokubanzi kumashishini esinyithi, ishishini lesamente kunye neglasi:
Ishishini leMetallurgical:esetyenziselwa ukufakwa kwezixhobo eziphezulu zokushisa ezifana nabaguquli, ii-arc zombane zombane, ii-firnaces ezivulekileyo, iileyile kunye neziqhumiso eziqhumayo kwishishini lensimbi, ngokukodwa ngokufanelekileyo kwimeko yokuphatha i-alkaline slag ephezulu.
...Umzi mveliso wesamente:isetyenziselwa indawo yokudubula kunye nendawo yotshintsho yeekhilni zesamente ezijikelezayo ukuxhathisa ukhukuliseko lobushushu obuphezulu kunye nomoya wealkaline.
Ishishini leglasi:esetyenziselwa ukuhlaziya kunye neengxenye eziphezulu zesakhiwo kwiziko lokunyibilika kweglasi, kwaye inokumelana nokhukuliseko lobushushu obuphezulu kunye nolwelo lweglasi yealkaline.
