Aluminium industry Today, aluminium is the second most-frequently used metal in the world. This is because aluminium has a unique combination of attractive properties - light weight, high strength, very easy to mould and excellent corrosion resistance are only the most important ones. Aluminium is one of the materials of the future. In the long term, the global trend in primary aluminium is very positive. According to forecasts, demand is expected to increase by 50 percent by 2050 and reach well over 100 million tons. Aluminium features very good recyclability and is one of the most commonly...

Alumina refinery for the highest demands Globally, most commercial alumina refineries use the Bayer process to refine aluminium oxide from bauxite ore. Extraction of aluminium from its ore and subsequent processing into finished products takes place in a series of successive operations that are largely independent of each other. The process conditions within the alumina refinery caustic concentration, temperature, pressure, flow and level - are set depending on the properties of the bauxite ore.The most significant risk in an alumina refinery is the mechanical overpressure of a digester. There,...

After the mixture of petroleum coke, resin, aggregates and recycled used anodes, the mass is shaped (“green anodes”). In the anode furnace, the green anodes are gradually heated to the range of 1,100 to 1,120 °C and slowly cooled again. The entire heating cycle can take 16 to 28 days. The goal of firing the green anode is to produce properties such as sufficient mechanical strength, thermal shock, high electrical conductivity, and low chemical reactivity. One of the main requirements of anode baking is that all anodes, regardless of their location, are exposed to the same temperatures. For the...

Primary aluminium smelter Productivity and cell efficiency The bath temperature is one of the most-important parameters for achieving optimum cell operation. It is necessary to measure the bath temperatures as frequently and as accurately as possible. Precise temperature control is crucial for the efficiency of aluminium plants. Our experience in manufacturing and calibrating temperature measuring instruments enables you to meet your exact requirements and standards. Thus, abnormalities in the cell can be detected and necessary measures taken to achieve a stable cell operation (e.g. addition...

Casting house High reliability for high availability Low weight with high strength, high load capacity and extreme flexibility – these are the characteristics of modern sophisticated aluminium alloys. The use of aluminium in the construction of modern transportation can save up to a third of the weight – and thus fuel. In the age of mobility, aluminium is the material of choice. The efficiency of a casting house is measured in cost per ton of aluminium produced. To increase this, it is essential to monitor the temperature of liquid aluminium. The flow temperature of the hot metal is determined...
