Aluminium features very good recyclability and is one of the most commonly recycled metals. Energy consumption during aluminium smelting is only five to ten percent of the energy used in new production.
The most significant risk in an alumina refinery is the mechanical overpressure of a digester. There, bauxite ore reacts with caustic soda under high pressure and high temperature. In the past, major explosions have occurred due to failures of process instrumentation devices and pressure relief systems, resulting in major damage to vessels and equipment.
The optimal use of raw materials, energy and process steam can be guaranteed by the use of reliable and accurate flow, pressure, level and temperature measuring instruments from WIKA to ensure strict process control.
One of the main requirements of anode baking is that all anodes, regardless of their location, are exposed to the same temperatures. For the anode furnaces, WIKA offers a range of accurate, reliable and robust measuring instruments designed to control high temperatures, ultra-low pressures and primary flow elements to optimise the anode baking process, significantly reducing the risk of low-quality anodes.
Thus, abnormalities in the cell can be detected and necessary measures taken to achieve a stable cell operation (e.g. addition of bath additives). WIKA offers a variety of solutions for reliable temperature measurement in aluminium reduction cells.
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.
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 while it flows through the channels.
For the temperature measurement of molten aluminium, immersion thermocouples from WIKA are durable and extremely precise.
Our particular strength lies in the project planning, development and the building of complete, individual, application-specific systems – from simple manual work stations through to fully automated test systems in production lines.
