Ibhloko ye-Magnesite chrome isebenzisa umgangatho we-magnesia kunye ne-chromic oxide njengento ekrwada, ibunjwe ngoxinzelelo oluphezulu kwaye itshiswe kwiqondo lokushisa eliphezulu. izitena ze-chrome ze-magnesia zineempawu zekristale enkulu kunye nezinga eliphezulu lokudibanisa ngokuthe ngqo. kunye nezitena zomlilo ze-magnesite chrome zinokuxhathisa okulungileyo kokuqhekeka kunye nokumelana nokukhukuliseka kwe-asidi ye-slag enepropati ephantsi ye-alkaline. Ibhloko ye-magnesite ye-chrome yeyona nto ifanelekileyo yezitena zombane zokuhombisa eziko, iziko lombane, iziko leglasi, isithando somlilo esinyibilikayo kunye ne-rotary cement kiln.
Ngenxa yomgangatho wezitena ze-magnesia chrome, isitena se-magnesia se-chrome sahlulwe ngokwezitena eziqhelekileyo ze-magnesia chrome, izitena ezidibeneyo ze-magnesia ye-chrome, isitena se-semi bonded magnesia se-chrome, isitena se-chrome esibotshiweyo njalo njalo.
Izitena ze-Magnesia ze-chrome zenziwe ngezinto ezidibeneyo eziqhelekileyo ze-sintered, kwaye ziphelise umphumo okhululekileyo obangelwa ukwanda xa uvelisa i-spinel ngokusabela kwe-MgO kunye ne-Cr2O3, i-Al2O3 okanye i-FeO. Ngaphezu koko, kukwakho nezitena zomlilo ze-magnesite ze-chrome ezingatshiyo ezifana nebhloko ye-chrome ye-magnesite engatshiyo yenziwe ngesisombululo se-saline ye-inorganic magnesia. kunye nezitena ze-chrome ze-magnesia ezingatshiyo zilula kwaye ziphantsi. olu hlobo lwezitena ze-chrome ze-magnesia lunozinzo olukhulu lwe-thermal, kodwa amandla alo aphezulu okushisa aphantsi kunezitena ezitshisiweyo ze-chrome ze-magnesia.

IMagnesia chrome isitena sisetyenziswa ikakhulu kushishino lwesinyithi, olufana nokwakha iziko elivulekileyo leziko, umphezulu womlilo weziko lombane, ngaphandle kwezinto ezihonjisiweyo kunye nazo zonke iintlobo zeziko lokunyibilikisa elingenawo i-ferrous. Ibhloko ye-magnesite chrome ikwasetyenziswa kwindawo yokutshisa indawo yeziko lesamente ejikelezayo kunye negumbi elihlaziyayo leziko leglasi.
Umzi-mveliso we-RS refractory ngumthengisi wezitena we-magnesia we-chrome owasekwa ekuqaleni kwe-90s yenkulungwane yamashumi amabini. Umzi-mveliso we-RS refractory ukhethekileyo kwizitena zomlilo ze-magnesite chrome iminyaka engaphezu kwama-20. ukuba unemfuno ethile yebhlokhi ye-chrome ye-magnesite, okanye unemibuzo malunga nezitena ze-magnesia chrome malunga nezikhombisi zomzimba kunye neekhemikhali, nceda uqhagamshelane nathi simahla. Umzi-mveliso we-Rs refractory njengomenzi wezitena zomlilo we-magnesite chrome e-china, uneengenelo ezithile zokukhuphisana ngolu hlobo lulandelayo:
