Waxqabadka lebenka refractory ee shooladda qaraxa kulul

Laydhka dib-u-milicsiga Foornooyinka kulul ee kulul waxaa ka mid ah leben dhoobo ah, leben silica ah, iyo leben ka celinaya aluminium sare (oo ay ku jiraan leben badan, leben sillimanite, leben andalusite, leben kyanite, leben cordierite).

Shuruudaha loo baahan yahay lebenka rogroga ee shooladaha qaraxa kulul waa: heerka gurguurta oo hooseeya, awood heerkul sare oo wanaagsan, iyo iska caabin shoog kulayl oo wanaagsan. Marka laga soo tago buuxinta shuruudaha kor ku xusan, leben la hubiyay oo loogu talagalay shooladaha qaraxa kulul waa in sidoo kale ay leeyihiin awood kulayl oo weyn.

Naqshadaynta foornada kulul ee kulul, si loo doorto lebenka refractory si macquul ah, waxaa lagama maarmaan ah in la fahmo xuduudaha waxqabadkeeda iyo isticmaalka xuduudaha deegaanka. Sababtoo ah cabbirrada farsamada saxda ah ayaa ah saldhigga si loo hubiyo hawlgalka caadiga ah ee qalabka!

Foornada kuleylka kulul waxay qabataa lebennada dahaarka-fudud: lebennada silica-fudud, lebennada dahaarka khafiifka ah ee diatomite, leben dhoobo khafiif ah, leben-aluminium-fudud leh, iwm.
