Stimir of Iceland has recently completed the refurbishment of the stub protection system at Alcan Aluminium Valais – Steg Smelter in Switzerland.
The collar mounting machine and collar filling machine at Steg have been completely rebuilt using Stimir technology to eliminate problems and deficiencies in the original designs by others.
Stímir's Collar Forming technology has been installed to ensure that the existing collar mounting machine is able to handle aluminium coil without blockages. The collar material is automatically fed, cut to length, formed into a collar around the rod stub and securely closed with a punched locking imprint.
Collar Filling technology from Stimir has also been installed; this novel sysem accurately measures and dispenses carbon paste into the alu-coil collars. The dispensing system ensures accurate and even distribution of the carbon paste, and provides a virtually dust-free operation without the spillage which has until now been a significant problem.
Together, the Stimir’s Collar Forming and Collar Filling technologies comprise an integrated Stub Protection System facilitating maximum anode shift life without unwanted anode stub erosion.
Stimir hf. is a solution provider to the primary aluminium industry, with particular focus on the Rodding Plant. All aspects of design and fabrication are undertaken at Stimir’s own facilities, ensuring total quality control and on-time delivery.
