Walxaha dib-u-celinta ee loo isticmaalo qashinka khatarta ah, weelka rotary-ga waxaa lagu dhalaa qaybo adag oo aan degganayn. Ujeedada calcination waa in la gubo qashinka khatarta ah si loo yareeyo heerka dhimista kulaylka haraaga wax ka yar 5% marka aysan jirin qolof Habka xulashada dib-u-celinta qashinka khatarta ah ee foornada foornada waa ka duwan tahay qaabka foornada wareega.
Qalabka refractory ee loo isticmaalo foornada wareega ee daaweynta qashinka khatarta ah, isku-dhafka kiimikada ee qashinka khatarta ah waa mid adag sababtoo ah noocyada kala duwan, sidaas darteed waxaa la go'aamiyay in isku-dhafka kiimikada ee qashinka khatarta ah lagu gubo heerkulka 700-1000 ee kilns rotary, iyo Halabuurka ugu muhiimsan ee sii daynta gaasta ka dib calcination ee wasakhda khatarta ah waa in yar oo acidic ah.
Dib-u-soo-celinta gaaska aashitada ah waxay leedahay xasillooni wanaagsan, AL2O3 SiO2 qashinka rotary kiln waa iska caabin wanaagsan oo daxalka ah iyo dib-u-soo-celinta shubka ah, marka la dooranayo walxaha soo-celinta, ma aha xulashada alaabta dib-u-soo-celinta, content Fe2O3 inta ugu badan ee suurtogalka ah sababtoo ah Fe2O3 FeCL3 waxay la falgashaa gaaska chlorine, wajiga gaaska, kacsan oo dheellitiran lebenka refractory, foornada wareega sibidhka waxaa caadi ahaan loo isticmaalaa iska caabinta daxalka ee alaabta ilaalinta deegaanka Magnesia leben spinel birta, qashinka khatarta ah ee weelka weelka wax ka celinaya maaha mid ku haboon, khatarta ah. Qashinka foornada wareega ee qashinka iyo kabka laga soo saari karo, waa in sidoo kale la doortaa sibidhka hoose ee kabka ah, sababtoo ah sibidhka CaO iyo falcelinta chlorine, samaynta wajiga dareeraha CaC1 waxay yaraynaysaa caabbinta kulaylka iyo xasilloonida heerkulka sare ee kabka.
Xulashada agabka refractory, kilnka wasakhda halista ah waa in uu isticmaalo walxaha refractory ee leh caabbinta xidhashada wanaagsan, xasiloonida kulaylka shoogga iyo iska caabinta daxalka. Habka wax soo saarka ee foornada wasakhda ah ee khatarta ah waxay guud ahaan qaadataa habka gubashada hoose. Qashinka khatarta ah ee dabaysha aasaasiga ah ee shidaalka ayaa ka soo gala hal jiho dhererka foornadana waa mid gaaban (saamiga dhererka dhexroorka guud ahaan waa 3-5m oo keliya). Dareen-celinta foornada waa mid sahlan, taas oo ah, falcelinta oksaydhka ee gubanaya. Ka mid ah alaabooyinka caadiga ah ee hadda jira, leben sic ah oo loo yaqaan 'mullite sic leben' ayaa ah badeeco ku habboon, iyo walxaha la tuuri karo ayaa la dooran karaa mullite.
