Lits'ebetsong tsa indasteri tse nang le mocheso o phahameng joalo ka tlhahiso ea samente, ho etsa tšepe le tlhahiso ea khalase, thepa e hanyetsang ke ea bohlokoa bakeng sa botsitso ba ts'ebetso le taolo ea litšenyehelo.Litene tsa spinel tsa Magnesia alumina, khetho e ntle ka ho fetisisa bakeng sa basebelisi ba indasteri lefatšeng ka bophara, e ikhetha ka botsitso bo ikhethang ba mocheso, ho hanyetsa mafome, le ho ba mosa tikolohong.Tataiso ena e hlalosa lintlha tsa bohlokoa tsa motheo tsa magnesia alumina spinel stone bakeng sa litlhoko tsa hau tsa indasteri.
1. Tlhaloso ea Magnesia Alumina Spinel Bricks
Litene tsa spinel tsa Magnesia alumina ke thepa ea maiketsetso ea alkaline e hanyetsang e entsoeng haholo-holo ka magnesium oxide e hloekileng haholo (MgO, 80%-92%) le aluminium oxide (Al₂O₃, 3%-14%). Mekhahlelo ea tsona e meholo ea kristale—periclase le magnesia-alumina spinel (MgO·Al₂O₃)—li theha sebopeho se tsitsitseng ka ho chesa mocheso o phahameng. Jwalo ka mokhoa o mong o se nang chromium ho fapana le li-refractories tsa setso, litene tsa spinel tsa magnesia alumina li qoba ho ntšoa ha chromium e chefo e nang le hexavalent, li latela ka botlalo maemo a tikoloho a lefats'e.
2. Matlotlo a Bohlokoa a Magnesia Alumina Spinel Bricks
Litšobotsi tse ikhethang tsa litene tsa spinel tsa magnesia alumina li kenyelletsa:
- ① Botsitso bo botle ba ho sisinyeha ha mocheso, bo mamella potoloho ea ho pholisa metsi ea 12-20 ho 1100°C;
- ② E hanela mocheso o phahameng ka ho fetisisa, e na le ntlha ea ho qhibiliha ea 2135°C le ho se sebetse hantle ha e jarisoa >1700°C;
- ③ Ho hanyetsa mafome le slag e matla khahlanong le slags ea alkaline, likhase tse nang le asiti le litšepe tsa alkali;
- ④ Matla a ka tšeptjoang a sebopeho, a nang le bongata bo boholo ba ≥2.90 g/cm³ le matla a ho sila a batang a ≥45 MPa.
3. Litšebeliso tse ka Sehloohong tsa Magnesia Alumina Spinel Bricks
Litene tsa Magnesia alumina spinel li loketse tikoloho e thata ea mocheso o phahameng: libaka tsa phetoho ea setofo sa samente, li-lining tsa tšepe, li-regenerator tsa setofo sa khalase, le li-lining tsa setofo sa petrochemical. Ho tenyetseha ha tsona ho etsa hore litene tsa magnesia alumina spinel li lokele mesebetsi ea alkaline le ea sepakapaka se tsoakiloeng.
4. Malebela a Khetho bakeng sa Magnesia Alumina Spinel Bricks
Ha o kgetha magnesia alumina spinel stones, tsepamisa maikutlo dintlheng tse tharo tsa bohlokwa: bapisa karolelano ya MgO/Al₂O₃ le sepakapaka sa tshebetso ya hao, netefatsa diparamitha tsa motheo tsa tekheniki (bongata ba bongata, ho hanyetsa ho thothomela ha mocheso), mme o hlahlobe disetifikeiti tsa boleng ba mofani wa thepa.Beha pele litene tsa spinel tsa magnesia alumina tse lekiloeng bakeng sa boemo ba hau bo ikhethileng ba indasteri ho netefatsa ts'ebetso e ntle le bophelo bo bolelele ba ts'ebeletso.
Litene tsa spinel tsa Magnesia alumina li kopanya ts'ebetso le botsitso, li etsa hore e be letsete le bohlale bakeng sa liindasteri tsa sejoale-joale tse nang le mocheso o phahameng. Khetha litene tsa spinel tsa magnesia alumina tse nepahetseng ho ntlafatsa ts'epo ea lisebelisoa le ho fokotsa litšenyehelo tsa tlhokomelo.
