China Zabwino kwambiri zosagwira njerwa za silika kuchokera ku fakitale yogulitsa fakitale ndi opanga | Rongsheng

Njerwa ya silika imakaniza asidi ndipo imakhala ndi kukana kukokoloka kwa asidi. Slica njerwa refractoriness pansi katundu ndi mpaka 1640 ~ 1690 ℃, zikuoneka koyamba kufewetsa kutentha ndi 1620 ~ 1670 ℃ ndi kachulukidwe weniweni ndi 2.35g/cm3. Njerwa yamoto ya silicon imatha kugwira ntchito kutentha kwambiri kwa nthawi yayitali ndikusunga bata popanda kusintha. Njerwa za Silicon rectory zili ndi zopitilira 94% za SiO2. Njerwa ya silicate imakhala ndi mphamvu zotentha kwambiri komanso kutsika kwamphamvu kwamafuta. Njerwa yamoto ya silicate imapangidwa ndi miyala ya silika yachilengedwe monga zopangira, zowonjezeredwa ndi mineralizer yoyenera kulimbikitsa quartz mu thupi lobiriwira lomwe limasandulika kukhala tridymite ndikuwotchedwa pang'onopang'ono kutentha kwa 1350 ~ 1430 ℃ pochepetsa mlengalenga. Kutentha mpaka 1450 ℃, pali 1.5 ~ 2.2% ya kuchuluka kwa voliyumu yonse. Kuwonjezeka kumeneku kudzapangitsa kuti mgwirizanowo ukhale wotsekedwa ndikuonetsetsa kuti zomangamanga zimasunga mpweya wabwino komanso mphamvu zomanga.

Katundu wa Silica Moto Njerwa

• Kukana kukokoloka kwa asidi,
• Kutentha kwakukulu,
• High refractoriness: 1690 ~ 1710 ° C,
• Mkulu RUL: za 1620-1670 ℃,
• Kukhazikika kwa Volume pa kutentha kwakukulu,
• Kukana kwamphamvu kwamafuta.

Kupanga kwa Njerwa yamoto ya silika

Silicon fire block ndi refractory njerwa kuti silica zili zoposa 93%, 50% -80% tridymite, 10% -30% ya cristobalite, quartz ndi galasi gawo, pafupifupi 5% -15%. Mapangidwe a mineralogical a njerwa ya silicate makamaka ndi quartz ndi quartz, komanso quartz yaying'ono ndi vitreous. Scale quartz, quartzite quartz ndi quartz otsalira amasintha kwambiri mu voliyumu chifukwa cha kusintha kwa mawonekedwe a kristalo pa kutentha kochepa, kotero kukhazikika kwa kutentha kwa njerwa ya silicate refractory kumakhala kosauka pa kutentha kochepa. Pogwiritsira ntchito, pansi pa 800 ℃ kuti muchepetse kutentha ndi kuzizira, kuti mupewe ming'alu. Choncho sikuyenera kukhala pansi pa 800 ℃ kutentha kudumpha kwa uvuni.

Njira Yopangira Njerwa ya Silica Fire

Njerwa zamoto za silicate zimapangidwa kuchokera ku quartzite yokhala ndi mchere wochepa. Akawotchedwa pa kutentha kwambiri, silika refractory njerwa mchere zikuchokera wapangidwa sikelo quartz, quartzite quartz, galasi ndi zina zovuta gawo timinofu timapanga pa kutentha kwambiri, ndipo AiO2 zili zoposa 93%. Pakati pa njerwa za silika zowotchedwa bwino, zomwe zili mu sikelo ya quartz ndizokwera kwambiri, zomwe zimawerengera 50% ~ 80%. cristobalit inali yotsatira, yowerengera 10% mpaka 30%. Zomwe zili mu gawo la quartz ndi galasi zimasinthasintha pakati pa 5% ndi 15%

Kugwiritsa ntchito njerwa yamoto ya silika

Njerwa zamoto za silika zimagwiritsidwa ntchito ngati zida zodzitchinjiriza zoteteza khoma lachipinda chophika ndi choyatsira moto mu uvuni wa coke, chipinda chotsitsimutsa ndi thumba la slag mu ng'anjo yamoto yopangira zitsulo, ng'anjo yamoto yonyowa ndi ng'anjo yosungunula magalasi, ndi malo ena olemetsa komanso pamwamba pa ceramic. ng'anjo yoyaka moto. Njerwa za silicate zitha kugwiritsidwanso ntchito potengera zolemetsa potentha kwambiri komanso pamwamba pa ng'anjo ya asidi yotseguka.
