Qalabka dib u celinta ee foornada lime

Foornada lime waxay inta badan u qaybsantaa foorno labajibbaaran iyo foorno wareegsan. Marka loo eego kala soocida alaabada la eryay, waxaa jira foorno lime iyo dhoobo dhoobo ah. Waxay u qaybsantaa aagga kulaylka ka hor, aagga rasaasaynta iyo aagga qaboojinta.

Dhab ahaantii, heerkulka isticmaalka aagga preheating ee sare ee foornada lime ma aha mid aad u sarreeya, laakiin alaabta ceeriin waxay u badan tahay inay keenaan nabar weyn oo ku saabsan lebenka refractory marka alaabta la gubo, iyo gaaska foornada waxay keeni doontaa kiimiko halis ah. daxalka lebenka refractory. Sidaa darteed, waa in aan fiiro gaar ah u leh xoogga, cufnaanta, xirashada caabbinta iyo iska caabinta daxalka ee lebenka refractory.

Inkasta oo aagga preheating uma baahna heerkul sare oo lebenka refractory, shuruudaha guryaha kale ee leben refractory aad u adag. Warshado badan ayaa isticmaala leben aluminium sare ah iyo leben dhoobo ah, kuwaas oo kala duwan.

aagga calcination. Aagga calcining waa meesha fal-celinta kiimikaad ee lebennada refractory ee loo isticmaalo foornada lime ay ugu xooggan tahay, aagga calcining sidoo kale waa heerka heerkulka ugu sarreeya. Markaa ka digtoonow markaad leben leedahay. Leh caabbinta shoogga kulaylka wanaagsan, iska caabinta daxalka iyo xirashada caabbinta. Isticmaal leben aluminium sare ah oo cufan.

Aagga calcination wuxuu markii hore isticmaalay leben cufan oo aluminium ah oo cufan. Si kastaba ha ahaatee, sannadihii ugu dambeeyay, isticmaalka lebenka refractory alkaline ayaa ka fiicnaaday, oo la jaan qaada gaaska lime. Waqtigan xaadirka ah, sababaha qiimaha awgeed, waxaa jira leben badan oo aluminium ah oo sarreeya, laakiin lebbiska fosfatetada iyo lebenka fosfatetada ah ayaa sidoo kale faa’iido leh. Waxay kuxirantahay caadooyinka isticmaalka iyo qiimaha unug kasta.

Si kastaba ha ahaatee, suurtagal maaha in la isticmaalo leben alkaline aagga rasaasta. Qaybaha u dhow aagga kulaylka ka hor iyo aagga qaboojinta, xidhashada iska caabbinta ayaa ka muhiimsan iska caabbinta daxalka. Warshado badan ayaa wali isticmaala lebenka refractory-alumina-sare leh oo leh iska caabin wanaagsan oo heerkul sare ah.

Kadibna waxaa jira aagga qaboojinta. Sababtoo ah marka lime-ku soo galo aagga qaboojinta, waxaa weli jiri doona kulayl badan oo gadaal iyo gadaal u qulqulaya aagga qaboojinta. Lebenka refractory ee aagga qaboojintu waa inay sidoo kale lahaadaan iska caabin xoqid, caabbinta qaboojinta degdega ah iyo kuleylka, iyo iska caabinta diirka. Laakiin marka foornada shafka ay leedahay dhexroor yar, warshado badan ayaa sidoo kale dooranaya leben dhoobo ah.
