Essay

This thesis describes the development of melting and treatment for the smelt of secondary copper for the manufacturing bars with 55 Siemens conductance and more using the horizontal continuous casting. The thesis proposes a new technology for the production of a cable-conductor product from secondary copper based on horizontal continuous casting that consists of 4 stages namely: - melting secondary copper with an exposed mirror of metal (copper includes less than 0,15% of oxygen); - flux melting metal (flux consists of: soda, quarts sand, borax (1:4,5:4,5)), the results of copper includes less than 0,05% of oxygen; - the treatment of molten copper by argon and then deoxidizing by an alloy of "lithium-calcium" composition (50% per lach), the results of copper have density of 8940 kg/m3, 58 Siemens electroconductivity (then flow raze of argon then being 0,8 m3/t copper); - horizontal continuous casting with the following parameters: - velocity of casting - 0,48 m/min; - space for drawing - 40 mm; - timefor drawing - 1 - 2 s; - time for pause - 5 - 6 s; - the angle of mould inclination to horizon - 15 O. The horizontal continuous casting has been shown to offer many advantages over wirebarce casting. The basic results of the work have found industrial implementation into the melting and treatment of secondary copper.
