Abstract (en)
[origin: EP0499117A2] The invention relates to a process for continuous casting of thin slabs or round ingots, with a diameter of 8-40 mm, of copper alloys which tend to segregate during solidification. <??>To improve the ductility and to prevent segregations, it is provided to electromagnetically stir the melt within the continuous casting mould, the stirring power being about 0.5-100 W/cm<3> and the takeoff speed of the cast strand in the range of 0.05-1.3 m/min. <??>The process according to the invention is preferably suitable for continuous casting of thin slabs of copper-nickel-tin alloys with about 9-18% nickel and 5-10% tin which are to have an extremely fine-grained structure. <IMAGE>
