Abstract Scope |
The continuous aluminothermic reduction of MgO that we have developed uses a suspension of submicron MgO particles in an Al melt as a reaction mixture. The experimental results we collected confirm that the aluminum melt reduces the MgO as effectively as Al powder. The reaction mixture was prepared by applying a dosing wire, with the core made of MgO powder and the cladding made of aluminum. The proposed solution was tested at the pilot level in a melting furnace with an atmosphere of flowing argon, equipped with an electromagnetic pump (EMP). The wire was continuously introduced to the melt through the vortex created in the charge-well of the EMP. This enables the aluminothermic reduction to take place continuously, at a speed regulated by changing the feed rate of the dosing wire, and opens up the possibility of planning a future production line of primary magnesium. |
