Abstract:A new horizontal electromagnetic stirring method in mold based on the orthogonal interaction between static magnetic field and DC current was put forward to overcome the solidification disadvantages such as micro pore, inclusion and columnar crystals joint in copper thin-slab’s horizontal continuous casting. Commercial production was experimented based on the physical simulation in laboratory. In the simulation, the flow rule of melt metal in mold of horizontal continuous casting with electromagnetic stirring is measured using ultrasonic Doppler velometer, and the result is inter confirmed with the solidification characteristics is tics of zinc cupronickel thin slab in industrial product, some advantageous results are obtained that, when the current is 400 A the inner micro-pores disappear, when the current is 500 A the center equiaxed crystal layers occur and when the current is to 800 A the inner-segregation decreases to zero.
Key words: copper melt; horizontal continuous casting; electromagnetic stirring; flow; solidification
