Njerwa za silicon carbide ndizofunika kwambiri zomangira ng'anjo zosiyanasiyana ndi ng'anjo zomwe zimatentha kwambiri komanso kukokoloka kwamphamvu. Njerwa za silicon carbide refractory zimakhala ndi ntchito yabwino kwambiri polimbana ndi kukokoloka koyipa kwa chilengedwe, monga kutentha kwambiri, kukana bwino kwa abrasive, kukana kugwedezeka kwakukulu, kugonjetsedwa kwambiri ndi asidi ndi kukokoloka kwa alkali slag komanso kuchuluka kwa kutentha kochepa. Refractory silicon carbide castable makamaka ntchito mbali zosiyanasiyana za uvuni simenti ndi denga la magetsi arc ng'anjo ndi zitsulo ladel.
Njerwa ya Silicon carbide imapangidwa kuchokera ku SiC yakuda yakuda. Gawo lalikulu la kristalo ndi SiC. Njerwa ya Refractory silicon carbide imapangidwa pofananiza chomangira, kusakaniza, kuumba ndi kuwombera. Kulimba kwa njenjete kwa njerwa ya silicon carbide ndi 9, motero, njerwa ya Silicon insulation carbide imakhala ndi kukana kwa asidi kwa slag.
Zopangira za njerwa za silicon carbide ndi silicon carbide, pafupifupi 72% -99%. Silicon carbide imatchedwanso moissanite, corundum sand kapena refractory sand. Njerwa ya silicon carbide refractory imapangidwa ndi mchenga wa quartz, petroleum coke kapena phula la malasha, ndi matabwa amatabwa, omwe amapangidwa ndi kutentha kwambiri kusungunuka mung'anjo yamagetsi.
Njerwa za Silicon carbide refractory zitha kugawidwa kukhala njerwa zadongo zomangika za silicon carbide, njerwa za Si3N4 zomangika za silicon carbide, njerwa za Sialon zomangira silicon carbide, njerwa za β-SiC zomangira silicon carbide, Si2ON2 njerwa zomangika za silicon carbide ndi njerwa za recrystal silicon carbide.

Refractory silicon carbide castable imagwiritsidwa ntchito makamaka pazigawo zosiyanasiyana za ng'anjo ya simenti ndi denga la ng'anjo yamagetsi yamagetsi ndi ladel yachitsulo. Komanso angagwiritsidwe ntchito m'malo otsatirawa.
RS refractory fakitale monga katswiri pakachitsulo carbide castable wopanga ku China, ndi ubwino zambiri mpikisano mu msika. ngati mukufuna refractory silicon carbide castable, kapena muli ndi mafunso pa silicon carbide refractory castable za zizindikiro zakuthupi ndi zamankhwala, chonde titumizireni kwaulere, tidzakupatsirani zida zapamwamba za silicon carbide.
