Brown oo isku qasan aluminium

Jaad Brown, magaca caanka ah waxaa sidoo kale loo yaqaannaa ciid dheeman, waa nin bunni ah oo lagu sameeyay alumina, walxo kaarboon, iyo saddex walxood oo ceeriin ah oo dhalaalay oo la dhimay foornada dabka ee korontada, markaa waa magacan.Maaddooyinka ugu muhiimsan ee kiimikaad ee jaadka buniga ah waa Al2O3, waxa ku jirana waa 95.00% -97.00%, waxa kale oo jira qadar yar oo kale oo ah Fe, Si, Ti, iwm. wanaagsan, kala duwan codsiga ballaaran, waa raqiis ah, oo si ballaaran loo isticmaalo.

Jaad bunni ah waa alaabta ugu muhiimsan ee leh aluminium aluminium, kookaha (anthracite), oo leh heerkul sare oo dhalaalay foornada koronto.Waxay ku habboon tahay in la shiido biraha sare, sida birta guud ee kala duwan., Bir been abuur ah oo kabka ah, naxaas adag, iwm, sidoo kale soo saari kara refractories horumarsan.Grungy-ga brown wuxuu leeyahay sifooyin nadiifnimo sare leh, crystallization wanaagsan, dareere xoog leh, fidinta fidinta fiilada hoose, iyo iska caabinta daxalka.Iyada oo daraasiin ka mid ah soosaarayaasha dabka u adkaysta, alaabtu waxay leedahay sifooyin qarxa, ma jiro budo, iyo dildilaac la'aan codsiga.Gaar ahaan, waxay aad uga badan tahay waxtarka waxtarka leh ee jasteas brown dhaqameed, taas oo ka dhigaysa isku-darka ugu fiican iyo buuxinta qalabka dib-u-celinta jaad brown.
