Aluminium smelter optimization

Save energy,
improve performance,
increase profit.

KAN-NAK is dedicated to the optimization of aluminium reduction cells, with a long know-how on cell design to minimize energy consumption and optimize productivity.

Overview

Smelter upgrade

KAN-NAK helps you maximize the shareholder value by finding the fastest and most economical way of implementing current increase projects. Save energy, save money.

Modeling

To bring your project to successful completion, we use thorough experience in the aluminum field as well as state of the art modeling tools and a long engineering experience.

Consulting

In both primary aluminium production and downstream business, we will share with you our extensive knowledge, acquired over more than 35 years of worldwide activity.

RuC^®

Ready-to-use cathodes will increase your operational margin by saving energy, reducing rodding, optimizing lifetime and increasing productivity.

Our services

Smelter upgrade
& current increase

With measurement campaigns, KAN-NAK checks both the current state of cells and their optimized state. Measurements performed include current distributions, voltage breakdown, shell temperature, heat fluxes, bath and liquidus temperature, ledge profile, magnetic field in the liquid metal, metal upheaval and cell stability.

Busbars can be modified while all cells are under production, with no impact on your production.

Lining can be optimized to achieve significant energy saving and improved cell life

Shells Cells can be restarted with 20 to 50% higher current by the use of a booster rectifier and temporary busbars

RuC^® Cathodes can be used to save energy, increase cell life, increase current efficiency, suppress the rodding operation and many more advantages

Our services
