INSTALLATION WITH ROTARY KILN FOR ALUMINIUM MELTING EXCLUDING USAGE OF SLATS WITH SCREENING AND SLAG COLLECTION Russian patent published in 2009 - IPC C22B7/00 C22B21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to installation for melting of the primary and secondary aluminium with screening and collecting of slag. Facility contains rotary kiln for aluminium melting excluding usage of salt bath, inside of which there are helical element, bleed channel implemented with required inclination located in isolated chamber, allowing window between hole of rotary kiln and spherical accumulator tank located lower in blind area and outfitted by rotary joint for providing of the constant inclination of bleed channel and ability of direct and continuous pouring with metal melt into reservoir, device for automatically continuous screening and collection of melting slag, built into the facility and double system of channels for withdrawing of effluent gases.

EFFECT: provision of qualitative removing of pollutants, essential saving of energy in melting furnace, cost saving for waste treatment and maintenance and replacement of worn spots.
