These pages treat essentially cell operation topics like alumina feeding, the aluminum fluoride balance or environmental issues. You find there the relations AlWeb is using on the interactive web pages and AlPrg employs for the PC software.

This website contains the basic equations and all the other relations that AlWeb, AlPrg and ATab are using to solve their tasks and problems (see Theory Contents). However you must be logged in on this website with your username and password to access some of these theory web pages.

The carbon anodes of the conventional conventional Hall-Héroult process are consumed during electrolysis and have to be replaced by new anodes. ATab investigates the behavior of the anode table during an entire anode change cycle period. With ATab you set the anode numbering layout and the anode change schedule. You observe visually and numerically the behavior of the anode table during the lifetime of individual anodes. In this way you optimize the anode table layout according to predefined criteria.

AlPrg is a collection of several PC program modules to determine production values or optimal parameters for aluminum smelting. With these modules you investigate production and consumption data or you determine the optimal setting of the cell voltage or alumina feeders. Interactive graphic user interfaces show the reaction of the electrolytic cell to changing input values. Please see the for the AlPrg users' guide the AlPrg Contents.
