Electric heating systems

Kanthal® electric heating systems for applications such as aluminium and steel processing deliver significant reductions in energy consumption compared to gas-heated systems. In fact, the net efficiency of Kanthal® electric heating systems is 70%, compared with only 20% for gas. The design of the system allows the radiation to be more accurately directed towards the target area – a highly efficient heating method.

Anode pre-heating station

Anode pre-heating station

Prior to pouring molten iron into the anode slot, it is critical that the temperature in the slot is raised to above 100°C (180°F) as quickly (in less than 1 minute) and evenly as possible. This improves the conditions for welding the stubs to the anode and securing the safety of the operation.

Anode stub drying station

Anode stub drying station

For safety reasons, anode stubs must be heated up to at least 100ºC (180ºF) to remove any traces of water or vapor - a potentially dangerous issue that also deteriorates the quality of the welded joint.

Cathode pre-heating station

Cathode pre-heating station

By heating the pre-assembled steel bar and cathode block, the Kanthal® solution eliminates the need to move, lift and/or position hot steel bars, a potentially dangerous process. It also ensures consistent positioning of the bars and even heat distribution.
