METHOD FOR TREATMENT OF DUMP SALT SLAG IN REMELTING OF SECONDARY WASTES OF ALUMINIUM AND ALUMINIUM ALLOYS

摘要

FIELD: metallurgy.;SUBSTANCE: method includes charging of aluminium into a furnace after drain during remelting of secondary wastes of aluminium alloys in a rotor furnace onto the surface of hot salt slag in the furnace, cooled salt dump slag in the volume of 20-30% from rated volume of wastes in the furnace, mixing of cold and hot slag as the furnace rotates for 1-2 min and unloading of the slag into a reservoir.;EFFECT: simplified process of grinding of salt slag produced in remelting of secondary wastes of aluminium and its alloys, reduced energy costs for its grinding and improved environmental capability of the process.
