Abstract:The effects of electromagnetic brake (EMBR) on the flow of liquid melt during continuous casting of cladding aluminium alloys are investigated by numerical simulation and validated by experiments. The results show that the EMBR can effectively damp the strong impingement of the two streams of melt, decrease the jet length and reduce the recirculation zone in the centre of the mould. When the casting speed is 200 mm min(-1), a 0.15 T direct current magnetic field can effectively constrain the mixing of different alloys in the molten pool. According to the parameters suggested by simulation, the cladding billet of Al-Si and Al-Mg alloys is successfully produced.
