Mipiringidzo ya nangula imaphatikizapo njerwa zoimitsidwa ndi matailosi opindika ndi kupanga njira zamitundu iwiri ya kukanikiza ndi kutsanulira. malingana ndi zofuna za makasitomala, sankhani zida zomwezo zomwe zimakhala ndi ng'anjo yowotchera yomwe imatha kuwombera kutentha kwambiri. nangula chipika ali ndi mphamvu mkulu, zabwino kukokoloka katundu kukana ndi zabwino spalling kukana, amene ali kwenikweni kukulitsa chimodzimodzi ndi ng'anjo akalowa refractory castable.
Njerwa ya nangula imapangidwa ndi bauxite yapamwamba kwambiri monga zopangira zomwe zili ndi aluminiyamu 48 ~ 80% ndipo zimapangidwa kudzera kukanikiza ndi kuwombera kutentha kwambiri. zitsulo za nangula zimagwiritsidwa ntchito kwambiri m'ng'anjo zotentha monga ng'anjo yowotcha, ng'anjo yamakampani a malasha ndi ng'anjo yamagetsi yamagetsi.

Mipiringidzo yamoto ya anchor imagwiritsidwa ntchito kwambiri padenga ndi makoma a ng'anjo yotenthetsera yokhala ndi mphamvu zambiri, makina abwino komanso magwiridwe antchito abwino a anti strip. komanso angagwiritsidwe ntchito mu ng'anjo matenthedwe monga kutentha ng'anjo, malasha mankhwala mafakitale uvuni ndi ng'anjo yamagetsi pamwamba ndi etc.
RS refractory fakitale ndi katswiri wogulitsa njerwa za nangula zomwe zidakhazikitsidwa koyambirira kwa 90s zaka makumi awiri. Fakitale ya RS refractory yakhazikika pa njerwa zozimitsa moto kwa zaka zopitilira 20. ngati muli ndi zofuna za nangula refractory block, kapena muli ndi mafunso pa nangula firebrick zokhudzana ndi zizindikiro zakuthupi ndi mankhwala, chonde titumizireni kwaulere. ndi Rs refractory fakitale monga akatswiri acid nangula refractory njerwa ku China, ali ndi ubwino mpikisano motere:
Mtengo Wopikisana: Pangani zinthu kukhala zopikisana pamsika wanu,
Zochitika Zambiri: Pewani ming'alu ndi kupotoza njerwa,
Mitundu Yosiyanasiyana: Sungani ndalama za nkhungu kwa inu,
Kuwongolera Kwabwino Kwambiri: Kukwaniritsa zofunika zamakasitomala,
Zogulitsa zazikulu: Kutumiza mwachangu,
Professional Packing: Pewani kuwonongeka ndikuteteza katunduyo pamayendedwe.
