Case Aluminium electrolysis

Production of aluminium is a power consuming process where large amounts of electric power is needed. Alumina, processed from bauxite, reacts with anode carbon in Hall-Héroult electrolysis cells to produce the aluminium metal.

Case Electric arc smelting furnaces

A key challenge in large industrial submerged arc electric furnaces is the lack of direct measurements of the furance hearth. The operating conditions in the furnace hearth, typically consisting of a coke-bed or a crater are so harsh with extreme temperatures and aggressive chemical conditions that measurement equipment will not survive long enough to make proper measurements.

Case Metal refining processes

In metal refining the aim is to obtain the specification of one or several chemical components within product specifications, while at the same time obtain a product temperature within a preferred narrow window within a defined margin above the melting temperature. At the same time, production amounts should be optimized, at a lowest possible cost.
