China Zirconia Corundum Njerwa fakitale ndi opanga | Rongsheng

Kufotokozera Kwachidule:

Zirconia corundum njerwa ndi mtundu wa thupi loyera lolimba lomwe limapangidwa kuchokera ku alumina ufa ndi pafupifupi 65% ZrO2 ndi 34% SiO2 ndi mchenga wa zircon mkati, ndi zirconia corundum firebrick imatsanuliridwa mu nkhungu itatha kusungunuka mu ng'anjo yamagetsi yosungunuka. zirconia corundum moto njerwa ndi zinthu asidi refractory ndi katundu osiyanasiyana mkulu makina mphamvu, zabwino matenthedwe mantha kukana, mkulu refractoriness pansi katundu, amphamvu kukokoloka kukana ndi mkulu kachulukidwe ndi etc. zirconia corundum refractory njerwa akhoza ankagwiritsa ntchito mu galasi ng'anjo, Ladle, ng'anjo yoyera yachitsulo, ng'anjo yosungunula yachitsulo yopanda chitsulo ndi zina zotero.


Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Zircon corundum block imapangidwa ndi mchenga wokhazikika wa zircon komanso zopitilira 64% zircon. zircon corundum fire block imatsanuliridwa mu nkhungu itasungunuka mu ng'anjo yamagetsi yamagetsi. mawonekedwe a lithofacies amakhala ndi eutectoid ndi magalasi magawo a corundum ndi zirconium plagioclase. zircon corundum refractory block petrographic structure imapangidwa ndi eutectoid ndi galasi gawo la corundum ndi zirconium clinopyroxene. midadada ya zircon corundum imakhala ndi mphamvu zamakina apamwamba, kukana kwamphamvu kwamafuta, kukana kwambiri pansi pa katundu, kukana kukokoloka kwamphamvu komanso kachulukidwe kakang'ono.

Makhalidwe a Njerwa ya Zirconia Corundum

  • High refractoriness pansi pa katundu,
  • Kulimbana bwino kwa kutentha kwa kutentha,
  • Kukana bwino kwa dzimbiri,
  • Mphamvu zamakina apamwamba,
  • Kulimbana kwakukulu kwamphamvu,
  • Kuchulukana kwakukulu.

Njira Yopangira Njerwa ya Zirconia Corundum

Njerwa ya Zirconia corundum imakonda kuchuluka kwa 1: 1 mchenga wa zircon ndi ufa wa alumina wa mafakitale ndikuwonjezera ma volume ochepa a NaZO, B20 wothandizila wosakanikirana mukamasakaniza bwino posungunula ndikutsanulira mu nkhungu pa kutentha kwakukulu kwa 1900 ~ 2000 ℃ kuchititsa njerwa zosakanizidwa zomwe zili ndi 33. % ZrO2 zomwe zili. Patsinde, tengani gawo la mchenga wa zircon wa desilicication ngati zopangira kuti mupange njerwa zosakanikirana ndi 36% ~ 41% ZrO2.

Gulu la Njerwa ya Zirconia Corundum

AZS-33
AZS33 zirconia corundum njerwa wandiweyani microstructure imapangitsa galasi kugonjetsedwa ndi kukokoloka kwa magalasi sikophweka kutulutsa miyala kapena zolakwika zina, ndipo kuthekera kopanga thovu laling'ono la gasi ndilotsika kwambiri.

AZS-36
Kuphatikiza pa eutectic yofanana ndi AZS-33 zirconia corundum firebrick, njerwa ya AZS-36 ya zirconia corundum chifukwa chowonjezera makristasi ochulukirapo ngati zirconia, ndipo magalasi amachepa.

AZS-41
Njerwa yamoto ya AZS-41 ya zirconia corundum imakhala ndi kugawa kofanana kwa makhiristo a zirconia, mu zirconia corundum mndandanda, kukana kukokoloka kwake ndikobwino kwambiri.

Kugwiritsa ntchito njerwa ya Zirconia Corundum

Zircon corundum midadada imagwiritsidwa ntchito makamaka mu ng'anjo yamagalasi yamafakitale, ng'anjo yamagetsi yamagalasi, ng'anjo yachitsulo yachitsulo ndi zitsulo, ng'anjo yamafakitale ya sodium metasilicate pokana kukokoloka kwamankhwala ndi makina pakutentha kwambiri.
