The Aluminium Remelt Plant produces aluminium logs that are used later in the extrusion process to produce extrusion profiles. Billets are short cylindrical solid pieces of aluminium with a diameter of 171mm and at Almin they are cut to lengths of 420mm, 525mm and 630mm respectively.

Re-melting of the scrap and the ingot is done in a reverbatory furnace, which is a liquid fuel fired furnace that has output capacity of about 5000kg per charge.

The furnace can use the following fuels interchangeably: used-oil, diesel, paraffin, or coal tar. Currently Paraffin is the predominant fuel.

This is carried out by heating the logs in an electric furnace at temperatures of 575 +/- 10 oC  depending on the alloy.
