Ibhulokhi ye-Magnesite chrome isebenzisa ikhwalithi ye-magnesia ne-chromic oxide njengento eluhlaza, ebunjwe ngomshini wokucindezela ophezulu futhi eshiswa kuzinga lokushisa eliphezulu. izitini ze-magnesia chrome zinezici zekristalu enkulu nezinga eliphezulu lokubopha okuqondile. kanye nezitini zomlilo ze-magnesite chrome zinokuphikiswa okuhle kokuqhekeka kanye nokumelana nokuguguleka kwe-acid slag enempahla ephansi ye-alkali. I-magnesite chrome block iyinsimbi efanelekile yezitini yokuhlobisa ngaphandle kwesithando somlilo, isithando somlilo sikagesi, isithando somlilo sengilazi, isithando somlilo esincibilikayo kanye nomlilo ojikelezayo usimende.
Ngenxa yekhwalithi yezitini ze-magnesia chrome, isitini se-magnesia chrome sihlukaniswe ngezitini ezijwayelekile ze-magnesia chrome, isitini se-chrome esiboshwe ngokuqondile, isitini se-chrome se-magnesia esihlanganisiwe, isitini se-chrome esiboshiwe nokunye.
Izitini ze-Magnesia chrome zenziwe ngezinto ezijwayelekile eziboshiwe, futhi zisusa umphumela oxegayo obangelwa ukunwetshwa lapho kukhiqizwa i-spinel ngokusabela kwe-MgO ne-Cr2O3, i-Al2O3 noma i-FeO. Ngaphezu kwalokho, kukhona nezitini zomlilo ze-magnesite chrome ezingashisiwe ezifana ne-chrome block ye-magnesite eyenziwe nge-inorganic magnesia saline solution. kanye nezitini ze-chrome ze-magnesia ezingashisiwe zilula futhi zibiza kancane. lolu hlobo lwesitini se-magnesia chrome sinokuzinza okukhulu kokushisa, kodwa amandla alo okushisa aphezulu aphansi kunezitini ze-chrome ezishisiwe ze-magnesia.

Isitini se-Magnesia chrome sisetshenziswa kakhulu embonini ye-metallurgical, njengokwakha isithando somlilo esivulekile, phezulu kwesithando somlilo kagesi, ngaphandle kwempahla ecolekileyo kanye nazo zonke izinhlobo zesithando somlilo esincibilikisayo esingeyona ayoni. Ibhulokhi ye-magnesite chrome nayo isetshenziswa endaweni yokushiswa kwendawo yomlilo kasimende ojikelezayo kanye negumbi elivuselelwe kabusha lesitsha sengilazi.
I-RS refractory factory ingumnikezeli wezitini we-magnesia chrome ochwepheshile owasungulwa ekuqaleni kwawo-90s wekhulunyaka lamashumi amabili. Ifektri ye-RS refractory ikhethekile ngezitini zomlilo ze-magnesite chrome iminyaka engaphezu kwengu-20. uma unesidingo esithile se-magnesite chrome block, noma unemibuzo ethile ngesitini se-magnesia chrome mayelana nezinkomba ezibonakalayo namakhemikhali, sicela usithinte mahhala. Imboni ye-Rs refractory njengomkhiqizi wezitini zomlilo we-magnesite chrome e-china, inezinzuzo ezithile zokuncintisana ngale ndlela elandelayo:
