Mefuta le mekhoa ea tlhahiso ea li-refractories tse bobebe

Sehloohong sena, baetsi ba litene ba refractory ba Henan ba batla ho bua le uena ka lihlopha le mekhoa ea tlhahiso ea li-refractories tse bobebe. Li-refractories tse bobebe li bua ka li-refractories tse nang le porosity e phahameng, boima bo tlase ba bongata le conductivity e tlase ea mocheso. Li-refractories tse bobebe li na le sebopeho sa porous (porosity ka kakaretso ke 40-85%) le ho kenya mocheso o phahameng.

Ho na le mekhoa e mengata ea lihlopha tsa li-refractories tse bobebe

1. E khethiloe ka boima ba molumo. Litene tse bobebe tse nang le boima bo bongata ba 0.4 ~ 1.3g / cm ~ 2 le litene tse khanyang tse nang le boima bo bongata bo ka tlase ho 0.4g / cm ~ 2.

2. Classified ka tshebetso mocheso. Mocheso oa mocheso oa kopo 600～900℃ ke lisebelisoa tse tlase tsa mocheso; 900～1200℃ ke thepa ea ho kenya mocheso o mahareng; ka holimo ho 1200 ℃ ke thepa ea ho kenya mocheso o phahameng.

3. E arotsoe ka sebopeho sa sehlahisoa. E ‘ngoe e entsoe ka litene tse bobebe tse bobebe, tse kenyelletsang letsopa, alumina e phahameng, silika le litene tse ling tse hloekileng tsa oxide lightweight; e ‘ngoe ke lisebelisoa tse sa tsitsang tse bobebe tse bobebe, joalo ka konkreite e bobebe ea refractory.

Tahlehelo ea polokelo ea mocheso le tahlehelo ea ho felloa ke mocheso holim’a ‘mele oa sebōpi sa indasteri hangata ke karolo ea 24 ho isa ho 45% ea tšebeliso ea mafura. Tšebeliso ea litene tse bobebe tse nang le mocheso o tlaase oa mocheso le mocheso o monyenyane oa mocheso kaha thepa ea sebopeho sa ‘mele oa sebōpi e ka boloka tšebeliso ea mafura; ka nako e ts’oanang, ka lebaka la sebōpi E ka futhumatsa le ho pholile ka potlako, e ntlafatsa ts’ebetso ea tlhahiso ea lisebelisoa, e fokotsa boima ba ‘mele oa sebōpi, e nolofatsa sebopeho sa’ mele oa sebōpi, e ntlafatsa boleng ba sehlahisoa, e fokotsa mocheso oa tikoloho. , le ho ntlafatsa maemo a mosebetsi.

Mefokolo ea li-refractories tse bobebe ke porosity e kholo, sebopeho se hlephileng le ho hanyetsa ha slag ho futsanehile. Slag e potlakela ho kenella ka har’a li-pores tsa setene, e etsa hore e senyehe, ‘me e ke ke ea sebelisoa ka ho toba ha e kopana le slag e qhibilihisitsoeng le tšepe ea metsi; e na le matla a tlaase a mochine, ho se mamelle ho se sebetse hantle, le ho se tsitse ha mocheso. E ke ke ea sebelisoa bakeng sa mehaho e jereng mojaro, leha e le hore e ka sebelisoa bakeng sa ho kopana le lisebelisoa tsa sebōpi le ho apara ka matla. Ea sebaka.

Ka lebaka la mefokolo e boletsoeng ka holimo ea lisebelisoa tsa refractory tse bobebe, likarolo tsa liindasteri tsa liindasteri tse amanang le tefiso, moea o chesang o jara slag, phallo e kholo, le likarolo tse nang le vibrate e phahameng ea mochini hangata ha li sebelisoe. Li-refractories tse bobebe li atisa ho sebelisoa e le ho boloka mocheso kapa lisebelisoa tsa ho boloka mocheso bakeng sa li-kilns.
