Lintho tse refractory

mohopolo:
Sehlopha sa lisebelisoa tsa inorganic non-metallic tse nang le refractoriness eseng ka tlase ho 1580 ° C.Refractoriness e bolela mocheso oa Celsius oo sampole ea refractory cone e hanyetsanang le ketso ea mocheso o phahameng ntle le ho kokobela le ho qhibiliha tlas'a boemo ba ho se be le moroalo.Leha ho le joalo, ke tlhaloso feela ea refractoriness e ke keng ea hlalosa ka ho feletseng lisebelisoa tsa refractory, 'me 1580 ° C ha e na ho feletseng.Hona joale e hlalosoa e le lisebelisoa tsohle tseo thepa ea tsona ea 'mele le ea lik'hemik'hale e lumellang hore e sebelisoe sebakeng sa mocheso o phahameng o bitsoa thepa ea refractory.Lisebelisoa tsa refractory li sebelisoa haholo ho metallurgy, indasteri ea lik'hemik'hale, peterole, tlhahiso ea mechini, silicate, matla le masimo a mang a indasteri.Ke tsona tse kholo ka ho fetisisa indastering ea metallurgic, tse etsang 50% ho 60% ea kakaretso ea tlhahiso.

phello:
Lisebelisoa tsa refractory li sebelisoa mafapheng a fapaneng a moruo oa naha joalo ka tšepe, litšepe tse se nang ferrous, khalase, samente, li-ceramics, lik'hemik'hale tsa petrochemicals, mechini, li-boilers, indasteri ea leseli, matla a motlakase, indasteri ea sesole, joalo-joalo, 'me ke lisebelisoa tsa bohlokoa ho netefatsa ts'ebetso ea tlhahiso le nts'etsopele ea theknoloji ea liindasteri tse ka holimo.E na le karolo ea bohlokoa le e ke keng ea nkeloa sebaka ho nts'etsopele ea tlhahiso ea indasteri ea mocheso o phahameng.
Ho tloha 2001, e susumetsoang ke nts'etsopele e potlakileng ea liindasteri tsa mocheso o phahameng joalo ka tšepe le tšepe, tšepe e sa tsitsang, lik'hemik'hale tsa petrochemical le thepa ea kaho, indasteri ea refractory e bolokile lebelo le letle la kholo mme e fetohile mohlahisi ea ka sehloohong le morekisi oa thepa ea refractory naheng. lefatshe.Ka 2011, tlhahiso ea China e ile ea nka hoo e ka bang 65% ea kakaretso ea lefats'e, 'me palo ea eona ea tlhahiso le thekiso e ile ea lula e le ea pele lefatšeng.
Ntlafatso ea indasteri e hanyetsanang e amana haufi-ufi le ho bolokoa ha mehlodi ya diminerale tsa lehae.Bauxite, magnesite le graphite ke lisebelisoa tse tharo tse kholo tsa refractory.China ke e 'ngoe ea linaha tse tharo tse rekisetsang bauxite kantle ho naha, e leng sebaka se seholo ka ho fetisisa lefatšeng sa polokelo ea magnesite, 'me ke se rekisetsang graphite kantle ho naha.Mehloli e ruileng e tšehelitse lisebelisoa tsa China tsa refractory bakeng sa lilemo tse leshome tsa tsoelo-pele e potlakileng.
Ka nako ea "Leano la Lilemo tse Mehlano", Chaena e potlakisa ho felisoa ha matla a tlhahiso a siiloeng ke nako le a phahameng a ho senya matla.Indasteri e tla tsepamisa maikutlo ho nts'etsopele le nts'etsopele ea libopi tse ncha tse bolokang matla, nts'etsopele ea theknoloji e felletseng ea ho boloka matla, taolo ea matla, taolo ea "litšila tse tharo" le ts'ebeliso ea lisebelisoa tsa "litšila tse tharo" Recycling, joalo-joalo. phepelo ea lisebelisoa le tšebeliso e ncha ea lisebelisoa tse haneloang kamora ho sebelisoa, ho fokotsa ho ntšoa ha litšila, ho ntlafatsa ts'ebeliso e felletseng ea lisebelisoa, le ho khothaletsa ka botlalo paballo ea matla le phokotso ea mesi.
"Leano la Ntšetso-pele ea Indasteri ea Refractory" le bontša hore tšebeliso ea yuniti ea thepa ea refractory indastering ea tšepe ea Chaena e ka bang lik'hilograma tse 25 ka thane e le 'ngoe ea tšepe,' me e tla oela ka tlase ho lik'hilograma tse 15 ka 2020. Ka 2020, lihlahisoa tsa Chaena li tla phela nako e telele. , e baballang matla, ha e na tšilafalo, 'me e sebetsa hantle.Lihlahisoa li tla khotsofatsa litlhoko tsa nts'etsopele ea moruo oa naha joalo ka tšepe, thepa ea moaho, lik'hemik'hale le liindasteri tse ntseng li hlaha, 'me li tla eketsa litaba tsa tekheniki tsa lihlahisoa tse tsoang kantle ho naha.

Lisebelisoa tsa refractory li na le mefuta e mengata le litšebeliso tse fapaneng.Hoa hlokahala ho arola ka mahlale lisebelisoa tsa refractory ho thusa lipatlisiso tsa saense, khetho e utloahalang le tsamaiso.Ho na le mekhoa e mengata ea ho arola lisebelisoa tsa refractory, ho kenyeletsoa karohano ea likarolo tsa lik'hemik'hale, likarolo tsa sebopeho sa liminerale tsa lik'hemik'hale, likarolo tsa ts'ebetso ea tlhahiso, le likarolo tsa morphology ea thepa.
