Abstract:

In this paper, research on reducing oxygen content and crack in oxygen-free copper strip during horizontal continuous casting process has been taken. First, reform the original copper alloy smelting-holding-casting three stages process. Through developing melting and holding integrative furnace, combine melting process and holding process for one, reforming smelting holding-casting two stages process. Second, pick up and realize on-off valve technics on controlling flow or stop of undercurrents copper liquid. Third, analyze the cracks in oxygen-free copper billet with flakinessratio 6500/20mm. And finally determine reasonable cooling process parameters through experiments. The results shows when oxygen content ≤0.0004% and density rise to 8.94-8.95 g/cm3, the crack has been completely eliminated.
