Electrically Heated Anode Copper Launder System

Achieve a long service life and lower life-cycle costs with efficient, low temperature operation. Electrically Heated Metso's Outotec Anode Copper Launder System offers a fully automatic, low energy consumption solution. Since all copper runs out of the launder and the launder is empty at the cast end, there is minimal skull to be remelted. The quality and recovery of the cast copper improves as less reject anodes are produced at the cast start.

Benefits

Low energy consumption: <10 kW/m
Automatic, silent operation, with no operator interference needed
Provides a longer launder life as the launder is insulated
Eliminates risks from propane
Always ready for casting
Minimizes fugitive gas emissions even during casting, and they can be easily captured
Increases flexibility:
- The length of the electrically heated launders is not limited
- Operates with low inclination
- An additional anode furnace may be constructed on the same elevation as existing ones.
Offers savings in AF operation:
- Lowers start temperature in casting, as there is less temperature loss
- Increases furnace lining lifetime due to lower furnace operating temperature

Automatic temperature control: reacts to temperature changes both at the cast start and end
Unique heating element means temperatures up to 1100°C can be continuously maintained in the launder
The heating element is resistant against creeping at high temperatures and in the casting atmospher

The launder comprises straight units for symmetry in thermal expansion. The curves made with the skew ends of the launder provide a curve for joints. The cover is insulated with ceramic wool and equipped with an electrical heating element.
