Njerwa ya AZS ndi njerwa yosakanikirana ya zirconia-corundum refractory yomwe ndi yolembedwa mwachidule kuti AZS kuchokera ku A ya Al2O3, Z ya ZrO2 ndi S ya SiO2. Monga No.33 wosakanizidwa kuponyedwa njerwa zirconia-corundum refractory njerwa kutengera AZS-33# monga chidule chake, No.36 wosakanizidwa kuponyedwa zirconia-corundum refractory njerwa kutengera AZS-36 # monga chidule chake ndi No.41 fused cast zirconia-corundum Njerwa yosasunthika imatengera AZS-41# ngati chidule chake.
Katundu wa AZS Njerwa
- Kutentha Kwambiri,
- Kukaniza kukokoloka,
- Katundu Wapamwamba Kwambiri,
- Katundu Wamakina Wabwino,
- Valani Resistance,
- Alkali kukana dzimbiri,
- Nthawi yayitali yautumiki.
Mapangidwe a Njerwa a AZS
Njerwa ya AZS yokhala ndi 33 ~ 45% ZrO2, imagwiritsa ntchito ufa wa alumina wa mafakitale ndi mchenga wosankhidwa bwino wa zircon monga zopangira, zomwe zimatsanuliridwa mu nkhungu zitasungunuka mu ng'anjo yosungunuka yamagetsi. mkati mwa chitsanzo cha jakisoni mutatha kusungunula kuzirala kwa ng'anjo yamagetsi ndi mawonekedwe oyera olimba, mawonekedwe a petrographic opangidwa ndi zirconium corundum ndi eutectoid yokhotakhota mwala ndi mawonekedwe a galasi.

Njira Yopangira Njerwa ya AZS ya Glass Furnace
Njerwa za AZS zimakonda kuchuluka kwa 1: 1 mchenga wa zircon ndi ufa wa alumina wa mafakitale, amawonjezera ma volume ochepa a NaZO, B20 agent of fusion mutatha kusakaniza bwino posungunula ndikutsanulira mu nkhungu kutentha kwa 1900 ~ 2000 ℃. zomwe zidapangitsa kuti chipika cha AZS chinali ndi 33% ZrO2. Patsinde, tengani gawo la mchenga wa zircon wa desilicication ngati zopangira kuti mupange njerwa zosakanikirana ndi 36% ~ 41% ZrO2.
Kugwiritsa ntchito njerwa ya AZS ya Ng'anjo
Njerwa za AZS za ng'anjo zimagwiritsidwa ntchito kwambiri ngati zida zowotcha kutentha kwambiri pokana kutsuka kwa kutentha kwambiri mung'anjo yamagalasi yamafakitale, ng'anjo yamagetsi yamagalasi, slide yachitsulo & chitsulo, silicate of soda industry ng'anjo. Njerwa yamoto ya AZS itha kugwiritsidwanso ntchito mung'anjo yosungunula zitsulo ndi chidebe chokana kukokoloka kwa slag.
