Stabilnost delovanja elektrolizne celice za pridobivanje aluminija ob uporabi različnih katodnih materialov : doktorska disertacijaČuš, ZlatkoZa lažje uvajanje materialov in kasnejše optimiranje parametrov je zelo koristno uporabiti simulacijski model pričakovanega stanja. V nalogi sem izračunal predvidene ekvipotencialne linije in smeri ... tokovnic znotraj EC s programskim paketom POLJE. Te vrednosti sem seveda poskušal verificirati z meritvami. V ta namen je bil razvit merilni sistem, ki omogoča sočasno merjenje toka skozi vse anode EC. Meritev tudi pomaga oceniti nivo nestabilnosti za posamezna tehnološka stanja in posamezne materiale. Za navedene nove materiale sem definiral metodologijo za določitev parametrov doziranja surovine in nove ravnotežne točke. Vse parametre sem verificiral v industrijskih razmerah. Za ta namen smo nove materiale vgradili v skupino osmih poskusnih EC. Za zmanjšanje stroškov pridobivanja aluminija sem uporabil statistični model standardne Gaussove porazdelitve. Napovedi so v zelo ozkem pasu dejansko doseženega in smatram, da je model zelo primeren za optimiranje industrijskih procesov. Pri vseh modelih sem za robne pogoje večinoma uporabil izmerjene vrednosti, ki se često zelo razlikujejo od teoretično predvidenih. Na osnovi določitve optimalnih parametrov stabilnega vodenja EC sem prišel do ugotovitve, da se lahko poveča produktivnost na račun povečevanja jakosti elekrtičnega toka pri isti tehnologiji. Za naše razmere je optimalna izbira materialov s 30% grafita, pri katerih lahko povečamo tok za okoli 3500 A brez sočasnnega poslabšanja ostalih parametrov.Type of material - dissertation ; adult, seriousPublication and manufacture - Maribor : [Z.
