BRIQUETTE MADE OF SECONDARY ALUMINIUM Russian patent published in 2009 - IPC C22B7/00 C22C21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to non-ferrous metallurgy field, particularly it relates to manufacturing of briquettes from secondary raw materials, particularly from secondary aluminium. Briquettes from secondary aluminium is received by pressing of mixture from grinned aluminium with admixture. In the capacity of aluminium it contains aluminium scrap with fraction size from more than 3 till 10 mm. In the capacity of addition it is included slag-forming component quicklime CaO in amount from more than 10 till 30% from the common mass of mixture, at that mass of received briquette is 15-2000 g. For receiving of AB-91 in the capacity of aluminium scrap briquette contains alimentary aluminium tin as the basis and no more than 10% of foil, for receiving of AB-87 in the capacity of aluminium scrap it contains alimentary aluminium tin as the basis no more than 10% of foil and no more than 10% of aluminium alloys chips, with briquette is implemented in the form of cylinder of diametre 10-15 mm and height from 15 till 200 mm.

EFFECT: increasing of cost-effectiveness of briquettes from the secondary raw materials.
