Kubadda caga -juglaynta (kubbadda kaydinta kulaylka)
1. Kubadda alumina ee sare waxay leedahay astaamaha iska -caabbinta oksaydhka ee xooggan iyo iska -caabbinta slag. Kubbadda dhoobada dhoobada si fudud ayaa loo beddeli karaa loona nadiifin karaa, oo dib loo isticmaali karaa.
2. Tilmaamaha ugu muhiimsan ee kubbadda jaban: Φ40mm Φ50mm Φ60mm Φ70mm
3. Agabka alaabta kubbadda jaban waxay u qaybsan yihiin: aluminium sare, corundum, iyo zirconium corundum.
4. Waxaa jira noocyo badan oo kubbadaha dib -u -ceshada ah, kuwaas oo loo adeegsan karo foornooyinka beddelidda heerkulka sare iyo kuwa hooseeya, dib -u -habeeyayaasha, beddelayaasha hydrogenation -ka, haamaha dhammaystirka, iyo kubbadaha dib -u -dhaca iyo qalabka ku -beddelidda kuleylka kuwaas oo lagu beddelay foorno kulul oo kulul oo ku jira warshadaha birta iyo birta .
5. Kubadaha dib -u -celinta kuleylka ee kaydinta kuleylka waxay leeyihiin faa’iidooyinka xoogga sare iyo iska -caabbinta xirashada; conductivity kaamerada weyn iyo awoodda kulaylka, oolnimada kaydinta kulaylka sare; kubadaha galaasyada kaydinta kulaylka waxay leeyihiin xasillooni kuleyl oo wanaagsan mana fududa in la jebiyo marka heerkulku si kedis ah isu beddelo. Kubadda kaydinta kuleylka ayaa si gaar ah ugu habboon buuxinta kaydinta kuleylka ee kaydinta kuleylka ee qalabka kala -soocidda hawada iyo foornada kuleylka foornada kuleylka kuleylka ee warshadda birta ah. Kubbadda kaydinta kulaylku waxay labanlaabtaa kulaylinta gaaska iyo hawada, iyo kubbadda dhoobada kaydinta kulaylka ayaa ka dhigaysa heerkulka gubashada inuu si dhakhso ah u gaadho birta duuban si uu u kululeeyo biilka. Shuruudaha.
6. Kubadaha dhoobada dhoobada dhoobada ah ee alumina, maadada alumina sare, cufnaanta sare, xoog farsamo sare, iska caabin wanaagsan oo duug ah, guryaha kiimikada deggan, iska caabin kulayl aad u fiican, kubadaha dhoobada alumina sare ayaa si weyn loo adeegsadaa, waxaana loo adeegsan karaa buuxinta kiimikada. Kubadaha dhoobada dhoobada ah ee alumina sare ayaa sidoo kale loo isticmaali karaa sidii warbaahinta shiidi. Kubadaha dhaadheer ee dhoobada dhoobada ah ee alumina ayaa si weyn loogu isticmaalaa kiimikada, farsamada, elektaroonigga, ilaalinta deegaanka iyo beeraha kale.
1. Kubad-celiyaha aluminiumka sare leh waxay badanaa tilmaamaysaa waxa ku jira Al2O3. Qodobka caanka ahi waa waxa ku jira oksaydhka aluminium ee ku jira alaabta ceeriin ee kubbadda jaban. Waxyaabaha aluminiumku waxay go’aamiyaan heerka guryaha kale duwan. Sidaa darteed, waa tusmada waxqabadka ugu weyn ee kubbadda jaban. Kubadaha cagajuglaynta ee aluminiumka sare ah waxaa loo qaybin karaa afar nooc iyadoo loo eegayo waxa ku jira aluminiumka: heerka aluminium ee heerka koowaad 75; kubadaha heerka sare ee aluminium-sare, ZN-65 oo leh 65% aluminium ka kooban; kubbadaha heerka saddexaad ee aluminium-sare, oo leh aluminium 55% ZN-55.
2. Cufnaanta bulk waa saamiga cufnaanta qalalan ee kubbadda jaban iyo muggeeda guud, halbeeguna waa g/cm3. Cufnaanta cufan waxay inta badan tilmaamaysaa isku -darka kubbadda jaban. Guud ahaan, cufnaanta tirada badan ee kubbadaha soo noqnoqda ayaa si aad ah ugu xiran xoolahooda iyo macdanta ay ka kooban yihiin. Kubbadda dib -u -ceshada, cufnaanta cufnaanta sare, ayaa ka sii fiican tayada alaabta. Cufnaanta mugga afarta nooc ee kubbadaha jaban waa: kubbadda alumina ee fasalka koowaad ≥ 2.5; kubbadda alumina ee fasalka labaad ≥ 2.3; kubbadda alumina ee fasalka saddexaad ≥ 2.1.
3. Porosity -ka muuqda waa saamiga mugga daloolada furan ee kubbadda diidmada iyo mugga guud. Guud ahaan, ceeryaanta iyo gaasaska waxyeellada leh ee kuleylku waxay ku baaba’iyaan kubbadda jaban lafteeda iyada oo daloolada furan. Sidaa darteed, waxaa loo baahan yahay in dabacsanaanta muuqata ee kubbadda jaban ay u yar tahay intii suurtogal ah. Dufanka muuqda ee afarta nooc ee kubbadaha jaban waa: kubadaha heerka-sare ee aluminium≤ 24%; kubbadaha heerka labaad ee aluminiumka≤26%; kubadaha heerka sare ee alumina≤28%.
4. Qiimaha iska caabbinta cadaadiska ee heerkulka qolka ayaa saamayn weyn ku leh wax soo saarka, gaadiidka iyo wax -qabadka kubbadda diidmada leh, sidaa darteed waxaa loo baahan yahay qiimaha iska -caabbinta cadaadiska sare. Cutubka waxaa lagu muujiyey KN. Qiyamka iska caabinta cadaadiska ee afarta nooc ee kubadaha soo noqnoqda ee heerkulka qolka waa: kubad aluminium sare oo gaar ah ≥ 25; kubbadda aluminium ee fasalka koowaad ≥ 15; kubbadda aluminium ee fasalka labaad ≥ 10; kubbadda aluminium ee fasalka saddexaad ≥ 8.
5. Heerkulka jilcinta culayska kubbadda jaban waxa loola jeedaa heerkulka uu ku xumaado inta la isticmaalayo.
