Lebenka heerkulka sare u adkaysta ee Kilns, foornooyinka
Sida laga soo xigtay qaybaha kala duwan ee leben refractory, waxaa loo qaybin karaa shan qaybood, kuwaas oo kala ah: leben refractory taxane Silicon-alumina, lebenka taxane alkaline refractory, lebenka refractory kaarboon-ka kooban, leben refractory zirconium-ka kooban, iyo leben refractory kulaylka.
Foorno kasta laguma dhisin hal nooc oo leben ah oo kaliya, waxay u baahan tahay isku-dar ah leben kala duwan oo kala duwan.
(1) Lebennada Silica waxay tixraacaan lebennada refractory oo ka kooban in ka badan 93% SiO2, kuwaas oo ah noocyada ugu muhiimsan ee lebenka caagga ah ee aashitada.Waxaa inta badan loo isticmaalaa foornooyinka kookaha ee dhoobada ah, laakiin sidoo kale waxaa loo isticmaalaa khasnadaha iyo qaybaha kale ee xamuulka qaada ee kilnnada kulaylka ee galaasyada kala duwan, ceramics, calciners carbon, iyo lebenka refractory.Waxaa loo isticmaalaa qalabka kulaylka ee ka hooseeya 600 ° C iyo isbedbeddelka heerkulka weyn.
(2) leben dhoobo ah.Lebenka dhoobada ah waxay inta badan ka kooban yihiin mullite (25% ilaa 50%), wajiga galaaska (25% ilaa 60%), iyo crristobalite iyo quartz (ilaa 30%).Caadi ahaan, dhoobada adag waxaa loo isticmaalaa sida alaabta ceeriin, clinker ayaa horay loo xisaabiyaa ka dibna lagu qaso dhoobo jilicsan.Qadar yar oo galaas biyo ah, sibidh, iyo qalabyo kale ayaa sidoo kale lagu dari karaa si loo sameeyo badeecooyin aan guban iyo walxo aan qaabaysan.Waa bulukeeti caadi ahaan loo isticmaalo foornooyinka qaraxa, shooladaha qaraxa kulul, foornooyinka kuleyliyaha, kululeeyaha korontada, kilnnada lime, kilns rotary, ceramics, iyo foornada toogashada leben refractory.
(3) Lebenka aluminium ee sare u kaca.Halabuurka macdanta ee lebenka aluminium-sare ee bulukeetiga ah waa corundum, mullite, iyo wejiyada galaaska.Maaddooyinka cayriin waa bauxite-alumina-sare iyo sillimanite dabiiciga ah, sidoo kale waxaa jira corundum isku-dhafan, aluminium sinteed, mullite synthetic, iyo clinker calcined leh alumina iyo dhoobo qaybo kala duwan.Inta badan waxaa soo saara habka sintering.Laakin alaabooyinka waxa kale oo ka mid ah leben isku qasan, leben isku daray ah, leben aan guban, iyo leben aan qaabaysanayn.Lebenka refractory High alumina waxaa si weyn loogu isticmaalaa in birta iyo warshadaha birta, warshadaha biraha non-ferrous, iyo warshadaha kale.(4) Lebennada Corundum refractory, lebenka corundum waxay tixraacaan nooc ka mid ah lebennada dib-u-celinta leh oo leh AL2O3 oo aan ka yarayn 90% iyo corundum oo ah wejiga ugu muhiimsan, kaas oo loo qaybin karo leben leben ah oo isku dhafan iyo leben corundum oo isku dhafan (5) Sare- alumina-kuleelka-dahiyaha bulukeetiga-fudud-fudud.Waa leben dahaaran oo iftiin leh oo leh bauxite oo ah nuxurka AL2O3 ugu weyn oo aan ka yarayn 48%.Habka wax-soo-saarka ayaa qaata habka xumbo, iyo habka isku-darka gubashada sidoo kale waa la isticmaali karaa.Lebennada khafiifka ah ee khafiifka ah ee aluminium-alumina-sare leh ayaa loo isticmaali karaa in lagu dhiso lakabyo kulaylka-damiya iyo meelaha aanay ka jirin wax nabaad guur ah oo heerkul sarreeya oo xooggan.Markaad si toos ah ula xiriirto ololka, heerkulka taabashada dusha sare ee lebennada celinaya kulaylka sare ee aluminium waa inuusan ka sarreyn 1350 ℃.Lebennada kululaynta kuleylka-Mullite waxay si toos ah ula xiriiri karaan ololka waxayna yeelan karaan astaamaha iska caabbinta heerkulka sare, xoogga sare, iyo saameynta tamar-badbaadinta cajiibka ah.Waxay ku habboon tahay dahaarka foornada pyrolysis, foornada kulul ee qarxinta, foornada dhoobada dhoobada ah, weelka mashiinka korantada ee korontada, iyo foornooyinka caabbinta ee kala duwan.(6) Lebennada khafiifka ah ee khafiifiya kulaylka dhoobada ah waa lebennada kuleylka kuleylka leh oo leh AL2O3 ka kooban 30% ilaa 48% oo laga sameeyay dhoobo refractory ah oo ah alaabta ugu weyn ee ceyriinka ah.Nidaamkeeda wax soo saarku waxay qabataa gubashada iyo habka dabeecadda iyo habka xumbo.Isticmaalka dhoobada refractory, kuul sabeynaya, iyo dhoobada caaga ah sida alaab cayriin ah, ku darida binder iyo balka, iyada oo loo marayo duubista, isku dhafka, samaynta, qalajinta, iyo toogashada, badeecada leh cufnaanta guud ee 0.3 ilaa 1.5g/cm3.Wax-soo-saarka lebennada kuleylka-celiska ah ee dhoobada ayaa ka dhigan in ka badan kala bar wadarta guud ee wax-soo-saarka leben-ka-celinta kulaylka.
Inta badan waxaa loo isticmaalaa foornooyinka qaraxa, foornooyinka kulul, foornooyinka kululaynta, foornada birta, foornooyinka kookaha, foornooyinka kaarboonka, suunka, hababka wax lagu shubo, kuleyliyaha, kilnnada sibidhka, weelka dhalooyinka, tunnel-ka, foornooyinka rotary, iyo foornada foornada kale ee kilns iyo qalabka kulaylka ayaa si weyn loogu isticmaalaa biraha, warshadaha kiimikada, ceramics, coking, carbon, tuurista, mishiinada, awoodda korontada, qalabka dhismaha, batroolka, iyo warshadaha kale.
