PCT No. PCT/SE95/01019 Sec. 371 Date Mar. 17, 1997 Sec. 102(e) Date Mar. 17, 1997 PCT Filed Sep. 11, 1995 PCT Pub. No. WO96/09131 PCT Pub. Date Mar. 28, 1996A device for slowing down the non-solidified portions of a cast strand during continuous casting of billets or blooms. The device comprises a group of at least three separate molds (1-4) which are open in the direction of casting and which are arranged such that each one is supplied with a flow of melt. The device also comprises a number of magnetic core parts (5-8), and at least one magnetic-field generating member (9-13), adapted to generate and transfer, together with the magnetic core parts, a static magnetic field or a periodic low-frequency magnetic field to the inflowing melt in such a way that the movement of the melt is slowed down. The magnetic core parts and the magnetic-field generating members are arranged such that, together with all the molds in the group, they form a common closed magnetic circuit. All the molds included in the group are arranged in series with each other in the closed magnetic circuit. |
