Smelting metal particles in between conductive rolls linked to voltage source, comprises varying the voltage between the rolls

摘要

Voltage between the electrically conductive rolls (3, 4) is varied during smelting. A method for smelting one or more metals in particle form comprises supplying the particles to a nip between two rolls comprising an electrically conductive material, linked to a voltage source (11). The voltage between the rolls is varied during smelting. An Independent claim is also included for the smelting apparatus.
