"Setene sa Magnesia-chromeke thepa ea motheo ea refractory e nang le magnesium oxide (MgO) le chromium trioxide (Cr2O3) e le likarolo tse ka sehloohong. E na le thepa e babatsehang e kang ho hanyetsa ho phahameng, ho hanyetsa mocheso oa mocheso, ho hanyetsa slag le ho hanyetsa khoholeho. Likarolo tsa eona tse ka sehloohong tsa liminerale ke periclase le spinel. Litšobotsi tsena li etsa hore litene tsa magnesia-chrome li sebetse hantle maemong a mocheso o phahameng 'me li loketse lisebelisoa tse fapaneng tsa indasteri ea mocheso o phahameng. "

Lisebelisoa le mokhoa oa tlhahiso"

Lisebelisoa tse ka sehloohong tsa litene tsa magnesia-chrome ke sintered magnesia le chromite. Magnesia e na le tlhokahalo e phahameng ea bohloeki, athe lik'hemik'hale tsa chromite hangata ke litaba tsa Cr2O3 pakeng tsa 30% le 45%, 'me CaO ha e fete 1.0% ho 1.5%. Mokhoa oa ho etsa tlhahiso o kenyelletsa mokhoa oa ho kopanya ka ho toba le mokhoa o sa chese. Ho kopanya ka ho toba litene tsa magnesia-chrome li sebelisa lisebelisoa tse tala tse nang le bohloeki bo phahameng 'me li chesoa ka mocheso o phahameng ho etsa karolo ea mocheso oa mocheso o tobileng oa periclase le spinel, e leng ho ntlafatsang haholo matla a mocheso le ho hanyetsa slag. "

Litšobotsi tsa ts'ebetso
"High refractory:Hangata refractoriness e ka holimo ho 2000 ° C, 'me e ka boloka botsitso bo botle ba sebopeho mocheso o phahameng.
Thermal shock resistance:Ka lebaka la coefficient e tlase ea ho atolosa mocheso, e ka ikamahanya le liphetoho tse matla tsa mocheso.
Slag resistance:E na le khanyetso e matla ea slag ea alkaline le slag e itseng ea acidic, 'me e loketse ka ho khetheha bakeng sa libaka tse pepesehileng ho slag e phahameng ea mocheso.
Corrosion resistance:E na le mamello e matla ho khoholeho ea acid-base chenchana le khoholeho ea khase.
"Ho tsitsa ha lik'hemik'hale:Tharollo e tiileng e entsoeng ke magnesium oxide le chromium oxide ka litene tsa magnesia-chrome e na le botsitso bo phahameng ba lik'hemik'hale.

Libaka tsa kopo
Litene tsa Magnesium-chrome li sebelisoa haholo masimong a indasteri ea metallurgic, indasteri ea samente le indasteri ea likhalase:

Indasteri ea metallurgic:e sebelisetsoang lesela la lisebelisoa tse phahameng tsa mocheso tse kang li-converter, libono tsa motlakase tsa arc, libōpi tse bulehileng tsa mollo, li-ladle le libōpi tse phatlohang indastering ea tšepe, haholo-holo e loketseng tikoloho ea ho sebetsana le slag ea alkaline ea mocheso o phahameng.

"Indasteri ea samente:e sebelisetsoang sebaka sa ho thunya le sebaka sa phetoho sa li-kilns tsa samente ho hanyetsa khoholeho ea mocheso o phahameng le sepakapaka sa alkaline.

Indasteri ea likhalase:e sebelisetsoang li-regenerator le likarolo tse ka holimo tsa sebopeho ka liboping tse qhibilihang ka khalase, 'me e ka mamella khoholeho ea sepakapaka se phahameng sa mocheso le mokelikeli oa khalase ea alkaline.
