Walaxda cayriin waa bir aan bir lahayn, iyadoo la isticmaalayo shooladaha korontada ku shaqeeya kuwaas oo dhalaaliya birta aan lahayn birta si ay u noqdaan dareere birta ah 1500 ~ 1600 ℃, ka dibna leh xawaare sare oo wareeg ah oo wareeg ah oo dhalaalaysa - soo saara fiilooyinka buuxinaya shuruudaha gaarka ah ee macaamiisheena. . Markay hoos u dhalaalayso dusha dareeraha birta taayirrada ah, birta dareeraha ah waxay ku garaacdaa booska iyadoo leh xoog centrifugal xawaare aad u sarreeya oo qaboojin leh. Taayirada ku dhalaali kara biyaha ayaa xajiya xawaaraha qaboojinta. Habkan wax-soo-saarka ayaa ah mid ku habboon oo wax ku ool ah soo saarista fiilooyinka birta ee alaabta iyo cabbirrada kala duwan.
Ku darista fiilooyinka birta aan fiicnayn ee kulaylka u adkeysata walxaha dib-u-soo-celinta amorphous (kabka, alaabta caagagga ah, iyo alaabta la isku dhejiyay) waxay bedeli doontaa qaybinta diiqada gudaha ee maaddada refractory, waxay ka hortagtaa faafinta dillaaca, u beddelo habka jabka jaban ee walxaha dib-u-soo-celinta jabka ductile, iyo si weyn u wanaajiso waxqabadka maaddada refractory.
Meelaha codsiga: korka foornada kuleylka, madaxa foornada, albaabka foornada, leben gubi, jeexjeexa hoose ee foornada, derbiga foornada annular, daboolka foornada, shaabadda ciidda, daboolka dhexdhexaadka ah, aagga foornada korantada, dahaarka birta kulul, qoriga buufinta dibadda sifaynta, daboolka birta kulul ee birta ah, xannibaadda slag, dahaarka kala duwan ee walxaha refractory ee foornada qaraxa, albaabka foornada, iwm.
socodka gaaban ee geedi socodka iyo saamaynta daawaha wanaagsan;
(2) Habka deminta degdega ah wuxuu ka dhigayaa fiilada birta inay leedahay qaab-dhismeedka microcrystalline iyo xoog sare iyo adag;
(3) Qaybta iskutallaabta ee fiber-ku waa bilaha aan caadiga ahayn, oogada ayaa si dabiici ah u qallafsan, waxayna leedahay adhesion xoog leh oo leh jaantuska refractory;
(4) Waxay leedahay awood heerkul sare oo wanaagsan iyo iska caabbinta daxalka heerkulka sare.
