METHOD FOR THE COMBINED CASTING AND ROLLING OF COPPER ALLOYS FROM COPPER SCRAP

摘要

The claimed inventions relate to non-ferrous metallurgy. A melt is prepared by melting copper. The copper melt is passed into a dispensing chamber through graphite with a density of 1.56-2.2 g/cm3 in the form of a perforated element at a temperature of 1140-1175°С. The copper is refined and reduced using a carbon-containing material under an elevated temperature. A continuous cast billet is formed and drawn and is rolled by being passed at a linear speed of 1.5-2.5 m/sec through an induction heater which provides high-temperature heating to 650-800°С, after which the billet is cooled suddenly to 50-55°С. This enables the production of a copper alloy with a low oxygen content.
