Theko ea litene tse refractory bakeng sa libono tsa metallurgical?
Theko ea litene tse refractory bakeng sa libono tsa metallurgical? Ena e ka ‘na ea e-ba potso eo metsoalle ea indasteri ea metallurgic e lokelang ho e tseba. Litene tsa refractory tse atisang ho sebelisoa liboping tsa metallurgical li kenyelletsa litene tsa silica, litene tsa corundum mullite, le litene tsa magnesia-iron spinel. Ho na le mefuta e mengata ea litene tsa refractory bakeng sa libono tsa metallurgical, ‘me theko e khethehileng e lokela ho buisanoa le moetsi ho khetha setene se loketseng ka ho fetisisa sa refractory. Lintlha tse latelang li kenyelletsa litene tsena tse sebelisoang hangata tsa metallurgical.
1. Sebopeho sa karolo ea diminerale ea litene tsa silika e entsoe haholo-holo ka tridymite le cristobalite, e nang le palo e nyenyane ea quartz le vitreous. Ka mocheso o tlase, molumo oa tridymite, cristobalite le quartz e setseng e fetoha haholo ka lebaka la phetoho ea sebōpeho sa kristale. Ka hona, botsitso ba mocheso oa litene tsa silika ka mocheso o tlase o futsanehile. Nakong ea tšebeliso, e lokela ho futhumatsoa butle-butle le ho pholile ka tlase ho 800 ° C ho qoba mapetsong. Ka hona, ha e ea lokela ho sebelisoa lioping tse nang le liphetoho tse potlakileng tsa mocheso ka tlase ho 800°C.
2. Setene sa Corundum mullite ke lisebelisoa tse phahameng tsa alumina tse refractory tse entsoeng ka corundum le mullite. Litene tsa Corundum mullite li bua ka lihlahisoa tse refractory tse entsoeng ka bohloeki bo phahameng kapa thepa e tala e batlang e hloekile. E na le matla a matle a mocheso o phahameng, ts’ebetso e phahameng ea mocheso o phahameng, ho hanyetsa mocheso oa mocheso le ho hanyetsa kutu. Ka bobeli li-stoves le litofo tsa ceramic li loketse.
3. Magnesium-iron spinel litene li entsoe ka boleng bo phahameng ba synthetic spinel e le lisebelisoa tse tala ‘me li sebetsoa ka mokhoa o khethehileng. Sehlahisoa se na le litšoaneleho tsa matla a phahameng a khatello, botsitso bo botle ba mocheso oa mocheso, ts’ebetso e ntle ea ho fofa ha mocheso, le mocheso o phahameng o nolofatsang mojaro. Ka nako e ts’oanang, e boetse e na le motsoako o tobileng oa litene tsa magnesia-chrome ‘me ho bonolo ho khomarela letlalo la sebōpi, le rarollang bothata ba tšilafalo ea tikoloho ea hexavalent chromium e hlahisoang nakong ea ho sebelisa litene tsa magnesia-chrome ka libotlolo tsa samente.
