Abstract:The double-ingot equipment of electromagnetic casting that consists of inductor, cooling water box, etc, was designed. The effects of inductor current and screen position on magnetic field distribution were investigated according to the measured results of series-connection inductor. From these results, the solidification front of melt should be controlled to the bottom of inductor. The key parameters such as casting speed, liquid column height and flow rate of cooling water are about 0.6~1.5 mm/s, 30~45 mm and 1.5~2.5 m3/h, respectively. And the round double-ingot with a diameter of 240 mm and a length of 400 mm was cast.

Key words: electromagnetic casting; double-ingots; forming experiment
