Refractories For Glass Furnace

Ezona zixhobo ziphambili ze-thermal zemveliso yeglasi, ezinje ngoxinaniso lwe-fusing, i-groove yesibini, ijelo lokutya kunye nokuxinana kwe-annealing, ubukhulu becala zenziwe ngezinto eziphikisayo.tinkonzo esebenzayo kunye nobomi benkonzo yesixhobo kunye nomgangatho weglasi ubukhulu becala buxhomekeke kuhlobo kunye nomgangatho wezixhobo ezisetyenziswayo.tInkqubela phambili yetekhnoloji yemveliso ixhomekeke ekuphuculweni kobuchwephesha bokwenziwa kwerefractory kunye nomgangatho kakhulu. Ngoko ke, kuyimfuneko ukukhetha ngokufanelekileyo kwaye wenzeit kubaluleke kakhulu ukusebenzisa i-refractories kuyilo kunye nokusebenza kwansuku zonke kwezixhobo zeglasi ezishushutowesibini yimeko yenkonzo kunye ne-corrosion mechanism yeendawo ezahlukeneyo zezixhobo ezishushufimathiriyeli yokuvutha ibhekisa kwizinto ezingaphiliyo okanye iimveliso ezinokumelana nomlilo ezingekho ngaphantsi kwe-1500 ℃ (1580 ℃ eTshayina nakwindawo eyayisakuba yiSoviet Union)iInokuba yimathiriyeli ekrwada yendalo, nayo inokuba yimveliso eyenziwe ngabantu kunye nemathiriyeli, izichasi ukongeza kwinqanaba elithile lokumelana nomlilo, kodwa kufuneka ube namandla

Umsebenzi ophambili wobugcisa wenkqubo:

① Ukuze kuhlangatyezwane neemfuno zokusebenza kobushushu obuphezulu, akufuneki kuthambe kwaye kunyibilike kwiqondo lobushushu eliphezulu ngokwaneleyo;

② Iyakwazi ukuthwala umthwalo wesithando somlilo kunye noxinzelelo kwinkqubo yokusebenza, kwaye ithwale uxinzelelo oluthile olubi kwiqondo lokushisa eliphezulu.;

Akukho lahleko yamandla esakhiwo, ukuguqulwa kunye nokungaphumeleli;

③ Uzinzo oluphezulu lweqondo lobushushu alukwazi ukuvelisa isithunzi esininzi okanye ukushwabana, ilitye elishinyeneyo lomlilo okanye umzimba othululwayo awuyi kucutheka ngenxa yokwandiswa komthamo.eiintanda okanye iintanda ezikhoyo;

④ Ukuxhathisa ukutshatyalaliswa kwe-thermal akuqhekeki phantsi kokutshintsha kweqondo lokushisa kunye nokutshatyalaliswa kwe-thermal;

⑤ Umsebenzi ochasayo wohlaselo unokumelana nentshukumo yexesha elide yerhasi, ulwelo kunye nendawo eqinileyo enomhlwa ngaphandle kokukhukuliseka okukhawulezayo, kwaye inokumelana nomhlwa.oukunciphisa i-xidation kwiqondo lokushisa eliphezuluitinokumelana nobushushu obuphezulu kunye nesantya esiphezulu sokuhamba kwedangatye kunye nomsi, ukukhukuliseka kwentsimbi engamanzi kunye ne-slag, kunye nokuhla koxinzelelo.iukugaya isinyithi kunye nezinye izinto;

② Uvandlakanyo lobushushu lokumelana nobushushu kunye nepropathi eshiyekileyo yesakhiwo ibhekisa ekuqhekekeni nasekuvavanyeni ukuhla komzimba wezitena okubangelwa kukutshintsha kobushushu. Ulwakhiwo.

Ukuwa kubhekiselele kwinto yokuba ukunyibilika kwee-refractories kuya kungena kwisitena kunye neepores zayo kunye nemijelo yokuqhekeka, kwaye isebenzisane nayo ukwenza isakhiwo esifanayo nesokuqala..

Xa iqondo lokushisa litshintsha ngokuphawulekayo, i-metamorphic layer enesakhiwo sezitena ezahlukeneyo kunye neempawu ziya kuqhekeka kwaye ziwe.

Umzi mveliso weglasi ukhethekile kuba indawo ekhukulisekileyo yeglasi eshinyeneyo yesulfure yomzimba iya kuhlala kwiglasi elulwelo ukuba inokunyibilika ngokupheleleyo..

Kwiglasi, ukubunjwa kweglasi kuchaphazeleka kuphela kwinqanaba elincinci, elingenabungozi kwiglasi enye, kodwa hayi kwiglasi ekhethekileyo..

I-Xu: ukuba ayinakuchithwa ngokupheleleyo, uluhlu lweziphene zeglasi ezifana namatye, amaqhuqhuva kunye namaqamza aya kwenziwa, okukhokelela kwimveliso yenkunkuma. Elinye icala.

Okwangoku, ubomi benkonzo yeglasi edadayo yaseTshayina ifikelele kwiminyaka engama-50.

Ngaphezulu kweminyaka esi-8, kodwa kusekho umsantsa omkhulu xa kuthelekiswa namazwe anoshishino lweglasi oluphuhlileyo. Ngoko ke, umgangatho we-refractory ngundoqo kumgangatho weglasi.

Imiba ephambili yophuhliso lwamashishini

Iimpawu zeerefractories zeglasi yomlilo

I-Refractories liqela leenkqubo ezininzi kunye ne-multicomponent complex, eziqulunqwe ngeendlela ezahlukeneyo zeekhemikhali ezahlukeneyo kunye neeminerali ezinezakhiwo ezahlukeneyo.

Iplastiki. Iipropati ze-refractories zihambelana ngokusondeleyo nokwakhiwa kweekhemikhali, ukubunjwa kwesigaba, i-morphology yokubambisana kunye nokusabalalisa, kunye neempawu zesigaba ngasinye.

ukwakheka kweekhemikhali

Ukwakhiwa kweekhemikhali ze-refractories yenye yezinto ezisisiseko ezimisela iimpawu ze-refractories.I-chemical composition of refractories inokwahlulwa ibe ngamacandelo amabini ngokokwakheka kunye nomsebenzi: icandelo eliphambili elibalela isixa esikhulu ngokupheleleyo kwaye lidlala isigqibo. Indima ekusebenzeni kwayo, kunye necandelo elincinci elibalela imali encinci libizwa ngokuba licandelo lesibini. Icandelo lesibini libandakanya icandelo lokungcola elikhapha i-raw material kunye necandelo elongezelelweyo elifakwe ngokukodwa ukuphumeza injongo ethile.

(1) Icandelo eliyinqununu kukuqulunqwa kwexesha lematriksi yomlilo kwii-refractories, ezidla ngokuba luhlobo olunye okanye iindidi ezininzi zee-oksidi zokutshisa ezinyibilikayo okanye ezingezizo ii-oxide ezenziwe zizimbiwa ezihlanganisiweyo. Ukusebenza kwayo kunye nobuninzi buchaza ngokuthe ngqo iimpawu zezixhobo zomlilo zexesha. Izinto zomlilo zexesha zingahlulwa zibe yi-asidi, i-alkaline kwaye ingathathi hlangothi ngokweekhemikhali zazo.

(2) Icandelo lokungcola libhekiselele kwizinto ezichasayo eziziswa okanye ezixutywe kwinkqubo yokuvelisa ngenxa yokusetyenziswa kwezinto zendalo zeminerali ekrwada.

Ngokuqhelekileyo, i-Ko, i-Nao, i-FeO kunye ne-FeO zizinto zomlilo zexesha

Ukungcola okuyingozi kwimveliso. Ukongeza, i-asidi oxide (i-ro2) kunye ne-asidi ye-asidi kwizinto ezisisiseko ze-pyrotechnic (i-RO iyona nxalenye ephambili) nazo zonyuswa.

I-oxides kwizinto ze-pyrotechnic zithathwa njengezinto ezinobungozi, ezinokulungiswa okunamandla kwiqondo lokushisa eliphezulu. Isiphumo asibonakali

Kuphela iqondo lobushushu lokubunjwa kwesigaba solwelo lwe-eutectic liyancipha kwaye inani lesigaba solwelo liyenyuka, kwaye ngokunyuka kwamaqondo obushushu, isixa sesigaba solwelo siyehla.

Isantya esikhulayo sikhawuleza, esichaphazela kakhulu ukusebenza kobushushu obuphezulu beemveliso eziphikisayo. Ngoko ke, kuyimfuneko ukulawula ukubunjwa kokungcola ngokuncinci kunokwenzeka

Ngokomzekelo, inxalenye ephambili yezitena ze-silica yi-SiO, kunye nezinto ezinobungozi ziquka i-Ao, ukuya kunye ne-alkali metal oxides. Umgangatho waseMelika

Kufunwa ukuba umxholo opheleleyo wokungcola kwi-silicon breaker yebakala elikhethekileyo ungaphantsi kwe-0.5%, kwaye umxholo we-Ao kwi-British standard silicon breaker yi-0.3%

Kukho iintlobo ezimbini zeziphumo eziguquguqukayo zokungcola kwi-refractories kunye nomxholo we-a1o ngaphantsi kwe-0.6%

(1)Ngenxa yokusabela kweekhemikhali, isigaba solwelo olunyibilikayo oluphantsi lwenziwa;(2)Isigaba solwelo esenziwe kubushushu obufanayo asikuko ukunyibilika okuphantsilubungakanani be-arge.

(3) Ukuze kuphuculwe ukusebenza komzimba, ukusebenza kwemveliso kunye nokusebenza kwe-refractory, ukongezwa kokwakheka kweekhemikhali kwimveliso okanye ukusetyenziswa kwe-refractory..

Inani elincinci lezongezo ezinokuthi zongezwe ukuphucula ukusebenza kwemveliso kuthiwa yi-additive. I-dosage yezongezo iyahluka kunye neempawu zabo kunye nemisebenzi, kwaye iphantsi ngokubanzi.

Ngamawaka alishumi ukuya kwipesenti ezimbalwa zokwakheka okupheleleyo kwezinto zepyrotechnic. Izongezo zinokwahlulwa ngokwezi ndidi zilandelayo ngokweenjongo kunye nemisebenzi yazo:

(1）Ixesha lezinto zomlilo ezidibeneyo zokudibanisa iklasi yokusebenza: i-binder, eyaziwa ngokuba yi-arhente yesamente okanye i-arhente emileyo;(2）lungelelanisa isethingi kunye nenqanaba lokuqina komgangatho: kubandakanya iarhente yokukhawulezisa, iarhente yepolar njalo njalo;(3）ukutshintsha iimpawu ze-rheological: kubandakanywa isinciphisi samanzi, iplastiki, i-gelling agent kunye ne-degumming agent, njl.(4）Lungisa umbutho wangaphakathi Iklasi yesakhiwo: kubandakanywa ne-agent ekhupha amagwebu, i-defoamer, i-agent shrinkable, i-ejenti yokuvuvukala, njl.;(5）ukuphucula iklasi yokuqina: kubandakanywa inhibitor, i-preservative, i-agent echasene nokudumba, njl njl. I-Cryoprotectants, njl. Ukuphucula ukusebenza, kuquka i-sintering aid, i-mineralizer, i-arhente yokomisa ngokukhawuleza, i-stabilizer, njl..

Kukho iintlobo ezininzi zezongezo, eziziizinto eziphambili zophando kwishishini lezinto zomlilo

Ngaphantsi: 2. Iyakwazi ukutshintsha ngokucacileyo imisebenzi ethile okanye iimpawu zeemveliso ezichasayo; 3. Ayinayo impembelelo enzulu kwiipropati eziphambili zeemveliso, ezifana nokuveliswa kwezitena ze-silica.

Ukongezwa kobisi lwekalika kunye nentsimbi yi-mineralizer ukuququzelela ukubunjwa kwe-quartz; I-Cao eyongeziweyo kwimveliso yi-stabilizer yokwenza imveliso izinzile.

Iziphumo zibonisa ukuba i-cubic ZrO 2 eyenziwe kubushushu obuphezulu izinzile kwiqondo lokushisa eliphantsi: i-MgO kunye nezinye izongezo ezicocekileyo eziphezulu ze-Al 2O iiseramics zi-sintering aids.hI-igh density sinter inokufumaneka kwiqondo lobushushu eliphantsi.
