This paper discusses a new individual anode current measurement scheme and its
applications in real-time monitoring and control of the Hall-Héroult process. While anode …

Computer control of aluminum reduction cells started in the early 1960s, first for energy input
by anode beam movement and alumina feeding by monitoring the change of cell resistance …

The measurement of individual anode currents in the Hall-Héroult process provides
localized information that can be used to improve cell operation. One promising application …

The strong demand for aluminium challenges the scalability of its primary production due to
the energy-intensity of the Hall-Héroult process, arising from high heat losses and other …

The recent finding of continuous background PFC co-evolution during apparently normal
operations of large operating smelting cells has raised the question as to whether or not …

Aluminium reduction cells consume about 1.9 kg of alumina for each kilogram of aluminum
they produce. Control of the alumina concentration within the electrolyte is of prime …

Alumina is an indispensable raw material for the modern aluminum electrolysis industry. The
distribution and transmission of alumina within the bath is of great significance to maintain …

Anode effects (AE) are considered a nuisance for aluminium production due to the
numerous negative impacts that they generate in an electrolysis cell. Previously, great efforts …

With the growth in sizes of the Hall-Héroult cells, the detection and diagnosis of faults in the
Hall-Héroult process is becoming more difficult, as the information from the cell resistance …

Busbar current distribution is an important aluminium electrolysis cell design and operation
parameter, which determines the electrical and magnetic equilibrium of the cell. Several …
