1282452 Continuous casting; making rod and wire METALLURGIE HOBOKEN 15 July 1969 [15 July 1968] 33834/69 Headings B3A and B3F In a process for continuously casting and hot shaping a copper bar of substantially square or rectangular cross-section, the bar 5 is cooled between four plane cooling surfaces so that heat is removed symmetrically and uniformly from each pair of opposite surfaces, and is then conveyed in a straight line to a device 8 for hot rolling. The copper is melted in a furnace 1 and fed via a tilting oven 2 to a continuous casting machine 3 of the type having two endless belts 4 co-operating to form a mould. Blocks (16), Fig. 2 (not shown), limit the width of the bar. After leaving the casting machine the bar is shielded by a neutral or reducing gas and a sheath 13 before passing through pinch rolls 6 into a rolling mill 8. The distances between the cooling surfaces of the mould and also between the pressure members of the rolling device may be varied. |
