Likarolo tse ka sehloohong tsa thepa ea refractory joalo ka litene tse phefumolohang, litene tsa li-nozzle block, le li-castable

Lisebelisoa tsa refractory li sebelisoa haholo ho metallurgy, theknoloji ea lik’hemik’hale, peterole le petrochemical, ho etsa mechine, ho sebetsa ka matla le masimo a mang a indasteri, ao palo e kholo ka ho fetisisa e sebelisoang indastering ea metallurgic. Lirapeng tsa tšepe le libōpi tse hloekisang indastering ea ho etsa litšepe, lisebelisoa tsa refractory tse atisang ho sebelisoa ke baetsi ba tšepe li kenyelletsa litene tse phefumolohang, litene tsa li-nozzle block, likoahelo tsa sebōpi sa motlakase, li-castable, lehlabathe la drainage, litene tsa khabone tsa magnesia, joalo-joalo. likarolo tse kholo le likarolo tse ekelitsoeng li fapane haholo. Ho tloha tlhahlobo ea lik’hemik’hale, lisebelisoa tsa refractory li entsoe ka liminerale, tse kang corundum, mullite, magnesia, joalo-joalo Likarolo tse ka sehloohong tsa tsona ke alumina le magnesia.

Ha e le karolo e ka sehloohong ea thepa ea refractory, ke karolo ea matrix e etsang thepa ea refractory, ke motheo oa litšoaneleho tsa thepa ea refractory, ‘me e khetholla ka ho toba thepa ea lihlahisoa tsa refractory. Ka mohlala, litene tse phefumolohang li lokela ho etsoa ka tšepe ea boleng bo phahameng, ebe li etsoa ka mekhoa e thata le e utloahalang, e le ho tiisa hore nako ea bophelo ea litene tse phefumolohang tse sebelisoang ke baetsi ba tšepe li ka finyella litlhoko. Likarolo tse ka sehloohong tsa thepa ea refractory e ka ba oxides (aluminium oxide, magnesium oxide, joalo-joalo), kapa likarolo kapa metsoako e seng oxide (carbon, silicon carbide, joalo-joalo).

Ho ea ka sebopeho sa likarolo tse kholo, lisebelisoa tsa refractory li ka aroloa ka mekhahlelo e meraro: acidic, neutral, le alkaline. Lintho tse nang le acidic refractory haholo-holo thepa e nang le acidic oxides joalo ka silicon oxide. Karolo e ka sehloohong ke silicic acid kapa aluminium silicate, e tla hlahisa letsoai tlas’a ketso ea mocheso o phahameng le alkali. Likarolo tse ka sehloohong tsa lik’hemik’hale tsa alkaline refractories ke magnesium oxide, calcium oxide, joalo-joalo Lihlahisoa tse tloaelehileng tsa refractory li kenyelletsa lehlabathe la drainage le li-slide tsa ladle. Li-refractories tse sa nkeng lehlakore ke li-refractories tsa carbonaceous le chromium. Ho phaella moo, li-refractories tse phahameng tsa aluminium (litaba tsa aluminium tse kholo ho feta 45%) ke li-refractories tse sa nke lehlakore tse atisang ho ba acidic, ha chromium refractories e atisa ho ba alkaline haholoanyane. Bakeng sa lisebelisoa tse sa jeleng paate, lisebelisoa tse tloaelehileng tsa aluminium tse phahameng li kenyelletsa litene tse phefumolohang, litene tsa li-nozzle block le likoahelo tsa sebōpi sa motlakase.

Khamphani ea rona e na le lilemo tse 18 tsa lipatlisiso le nts’etsopele, tlhahiso le thekiso ea thepa ea refractory joalo ka litene tse phefumolohang, litene tse thibelang molomo, li-castable le liforomo tse nang le tokelo ea molao, meralo e ikhethang, le ts’ebetso e thata le e tloaelehileng ea ts’ebetso ka ‘ngoe, e le hore baetsi ba tšepe ba ka li sebelisa. ka kgotso ya kelello le boiketlo.
