I-China Izitini ze-silica ezikwazi ukumelana nomlilo ezinhle kakhulu ezivela efektri yokuthengisa kanye nabakhiqizi | Rongsheng

Incazelo emfushane:

Isitini somlilo se-silicon singokwezinto eziphikisayo ze-silicon, isitini se-silica siwuhlobo lwemikhiqizo yekhwalithi ye-refractory enokuqukethwe okungaphezulu kuka-93% we-SiO2. Isitini se-silicate refractory sinezici ezinhle kakhulu zokumelana nokugqwala kwe-asidi, ukushisa okukhulu, ukuqina okuphezulu ngaphansi komthwalo ongaphezu kuka-1620 ℃. kanye nezitini ze-silica zinokuqhekeka kokumelana nokuguguleka kwe-asidi ye-slag eqinile, i-refractoriness ephezulu ngaphansi komthwalo, kanye nokuzinza kwevolumu ekushiseni okuphezulu. I-silicon rerfractory brik isetshenziswa kakhulu kuhhavini we-coke, iziko elivulekile, ihhavini lengilazi, i-ceramic kiln, i-blast furnace, njll.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isitini se-silica refractory siyayiphikisa i-asidi futhi inokumelana nokuguguleka kwe-acid slag. I-Slica bricks refractoriness ngaphansi komthwalo ifika ku-1640 ~ 1690 ℃, izinga lokushisa elibonakalayo lokuqala lokuthambisa lingu-1620 ~ 1670 ℃ futhi ukuminyana kweqiniso ngu-2.35g/cm3. Isitini somlilo se-silicon singasebenza ngokushisa okuphezulu isikhathi eside futhi sigcine ukuqina kwevolumu ngaphandle kokuguqulwa. Isitini sokuvuselela i-silicon siqukethe okuqukethwe kwe-SiO2 okungaphezu kuka-94%. Isitini se-silicate sinamandla aphakeme okushisa aphezulu kanye nokumelana nokushaqeka okuphansi kokushisa. Isitini somlilo se-silicate senziwe nge-silica ore yemvelo njengempahla eluhlaza, yengeza i-mineralizer efanelekile ukukhuthaza i-quartz emzimbeni oluhlaza oguqulwa ube yi-tridymite futhi iqhunyiswe kancane ngezinga lokushisa elingu-1350 ~ 1430 ℃ ekwehliseni umkhathi. Lapho kushisa kufika ku-1450 ℃, kubalwa u-1.5 ~ 2.2% wesamba sokunwetshwa kwevolumu. Lokhu kwandiswa emva kokwandiswa kuzokwenza ukusika okuhlangene kuvalwe uphawu futhi kuqinisekise ukuthi ukwakhiwa kugcina umoya omuhle ongangenisi kanye namandla esakhiwo.

Izakhiwo ze-Silica Fire Brick

Ukumelana kahle nokuguguleka kwe-asidi,
Amandla okushisa aphezulu,
I-refractoriness ephezulu: 1690 ~ 1710°C,
I-RUL ephezulu: mayelana ne-1620-1670 ℃,
Ukuzinza kwevolumu ekushiseni okuphezulu,
Ukumelana nokushaqeka okuhle kokushisa.

Ukwakhiwa kwesitini somlilo we-Silica

I-Silicon fire block iyisitena esiphikisayo ukuthi okuqukethwe kwe-silica kungaphezu kuka-93%, 50% -80% we-tridymite, 10% -30% wesigaba se-cristobalite, i-quartz nengilazi, cishe u-5% -15%. Ukwakheka kwe-mineralogical yezitini ze-silicate ikakhulukazi i-quartz ne-quartz, kanye nenani elincane le-quartz ne-vitreous. I-quartz yesikali, i-quartz ye-quartz kanye ne-quartz esele ishintsha kakhulu ngevolumu ngenxa yokushintsha kwesimo sekristalu ekushiseni okuphansi, ngakho-ke ukuzinza okushisayo kwesitini esiphikisayo se-silicate akubi kahle ekushiseni okuphansi. Enqubweni yokusebenzisa, ngaphansi kuka-800 ℃ ukunciphisa ukushisa nokupholisa, ukuze ugweme ukuqhekeka. Ngakho-ke akufanele kube ngaphansi kwezinga lokushisa elingu-800 ℃ kuhhavini.

Inqubo Yokukhiqiza Izitini Zomlilo we-Silica

Izitini zomlilo ze-silicate zenziwe nge-quartzite ngenani elincane le-agent ye-mineralizing. Lapho kushiswa ngezinga lokushisa eliphezulu, ukwakheka kwezitini ze-silica refractory amaminerali kwenziwa nge-quartz yesikali, i-quartzite quartz, ingilazi nezinye izicubu zesigaba eziyinkimbinkimbi ezakhiwe ekushiseni okuphezulu, futhi okuqukethwe kwe-AiO2 kungaphezu kwama-93%. Phakathi kwezitini ze-silica ezibaselwe kangcono, okuqukethwe kwe-quartz yesikali kuphakeme kakhulu, kubalwa ku-50% ~ 80%. cristobalit kwaba ngokulandelayo, ibalwa 10% kuphela 30%. Okuqukethwe kwesigaba se-quartz nengilazi kushintshashintsha phakathi kuka-5% no-15%

Ukusetshenziswa Silica Fire Brick

Izitini zomlilo ze-silica zisetshenziswa kakhulu njengezinto eziphikisayo zodonga oluvikelayo lwegumbi lokubhaka kanye ne-combustor kuhhavini ye-coke, igumbi lokuvuselela kabusha kanye nephakethe le-slag esithandweni somlilo esivulekile sensimbi, isithando somgodi esicwiliswayo nesithando somlilo esincibilikisa ingilazi, kanye nezinye izindawo ezithwala isisindo nangaphezulu ku-ceramic. umlilo wokudubula. Izitini ze-silicate nazo zingasetshenziselwa indawo yokuthwala isisindo lapho izinga lokushisa eliphezulu liphezulu nangaphezulu kwesithando somlilo esivulekile esine-asidi.
