zircon firebrick amatanthauza njerwa refractory yomwe ili ndi zipangizo za zircon kapena ZrO2 kuposa 90%. Kupatula apo, pali njerwa zina zokanira zomwe zili ndi zircon, monga njerwa ya Zr-Al, zirconia firebrick zimatha kupititsa patsogolo kukana kwamphamvu kwamafuta; Zr-Cr-Al njerwa, zomwe zimathandizira kukana komanso kukana dzimbiri; ndi njerwa ya Zr-SiC yomwe imapangitsa kuti slag ndi kuvala kukana. Njerwa za zirconia zosiyanasiyana zamphamvu zamakina apamwamba, kukana kwamphamvu kwamafuta, kukana kwambiri pansi pa katundu, kukana kukokoloka kwamphamvu komanso kachulukidwe kake.
Chotchinga chamoto cha zircon chimapangidwa kuchokera ku mchenga wokhazikika wa zircon ndi mtundu wa njerwa zazikulu zosakanizika zomwe zili ndi zircon zoposa 64%. Zircon refractory block ndi acid refractory yokhala ndi mphamvu zamakina apamwamba kwambiri, kukana kwambiri ponyamula katundu, kukhazikika kwamphamvu kwamatenthedwe, kukana bwino kukwawa komanso kukana kwa dzimbiri kwamadzi agalasi.

Njerwa za Zircon zitha kugwiritsidwa ntchito kwambiri mung'anjo yamagalasi, Ladle, ng'anjo yachitsulo yoyera, ng'anjo yachitsulo yopanda chitsulo, komanso njerwa zamoto za zirconia ndizoyenera ng'anjo yamagalasi, ng'anjo yosungunula yopanda chitsulo, ndi ng'anjo ya ladle, ndi zina zambiri.
Fakitale ya Rongsheng refractory yakhala ikulimbikitsa kupanga njerwa zamoto za zircnia kwazaka zambiri. Kampani ya RS ili ndi chidziwitso chokwanira chopanga komanso ukadaulo wapamwamba wopanga. alinso ndi injiniya waluso kuti akupatseni upangiri waukadaulo pakugwiritsa ntchito kwanu kwenikweni. Ngati muli ndi funso lokhudza zirconia block, chonde titumizireni kuti mudziwe zambiri zaukadaulo, malonda athu adzakuyankhani nthawi yoyamba.
