In an era of rising electricity costs and the need to reduce the environmental impact of industry, energy efficiency has become a key priority for the industrial sector. One area where savings can be particularly high is in liquid aluminium furnaces heated with alumina heaters. These processes require precise temperature control, which is associated with high energy consumption. In this article, we will discuss how the use of PID controllers and thyristor controllers from JUMO can help save energy and improve operational efficiency.
Liquid aluminium furnaces are key equipment in metallurgical processes such as casting or the production of aluminium components. To ensure proper alloy quality and avoid defects in the final products, the temperature in the furnace must be precisely controlled and kept constant. Alumina heaters, known for their high temperature resistance and durability, are used for heating. However, their efficiency and lifespan depends largely on how they are controlled.
Inadequate temperature control leads to excessive energy consumption and frequent overshoot, which can affect product quality and heater life. It is therefore necessary to implement advanced control technologies such as PID controllers and thyristor controllers.
PID controllers are sophisticated tools for maintaining stable conditions in industrial processes. The operation of a PID controller is based on three components:
In liquid aluminium furnaces, PID controllers ensure that heater output is precisely matched to current heat requirements, eliminating excessive temperature fluctuations. As a result, electricity is used more efficiently and the aluminium melting process is more stable.

Thyristor controllers are electronic devices that allow precise control of the power supplied to alumina heaters. They operate on a fast-switching principle, allowing real-time current regulation. Their key advantages are:
In liquid aluminium furnaces, thyristor controllers are crucial in minimising energy losses due to overheating.

The combination of PID controllers and thyristor controllers is the optimal solution for liquid aluminium furnaces. The PID controller precisely determines the amount of energy required to maintain the temperature, while the thyristor controller delivers this energy in a smooth and controlled manner.
Thanks to this synergy:
The implementation of PID controllers and thyristor controllers in liquid aluminium furnaces brings numerous benefits:
In practice, many metallurgical and aluminium processing companies have already implemented systems based on PID controllers and JUMO thyristor controllers. In one production plant, the use of these technologies has reduced energy consumption and increased the life of the heaters.
The use of PID controllers and JUMO thyristor controllers is a proven solution for significantly improving energy efficiency in liquid aluminium furnaces. Their implementation not only reduces operating costs, but also supports the minimisation of the carbon footprint, an increasingly important goal in the industry.
The future of control technology lies in integration with IoT systems and artificial intelligence, which will enable even more precise process management. Investing in these solutions today will give you a competitive advantage and contribute to building a more sustainable industry.
