Document Type and Number:
WIPO Patent Application WO/2018/014663
Kind Code:
A1
Abstract:
A vertical electromagnetic braking device for controlling a flow of molten steel in a continuous casting crystallizer, comprising horizontal magnetic poles (1), a magnet exciting coil (2), vertical magnetic poles (3) and a magnet yoke (5); the device comprises two pairs of the vertical magnetic poles (3), one pair or two pairs of the horizontal magnetic poles (1). When the device comprises one pair of the horizontal magnetic poles (1), the pair of the horizontal magnetic poles (1) are located below an intrusive type water opening (4), and arranged along a wide face of the crystallizer (7); when the device comprises two pairs of the horizontal magnetic poles (1), said poles are respectively referred to as upper horizontal magnetic poles (1) and lower horizontal magnetic poles (1), the lower horizontal magnetic poles (1) are located below an intrusive type water opening (4) and arranged along a wide face of the crystallizer (7), the upper horizontal magnetic poles (1) are located near a surface of the molten steel in the crystallizer (7) and arranged along the wide face of the crystallizer (7). The two pairs of the vertical magnetic poles (3) are respectively arranged near two side face areas of the crystallizer (7) and intersect with the one pair of horizontal magnetic poles (1) or two pairs of horizontal magnetic poles (1); both the magnet exciting coil (2) and the magnet yoke (5) are matched with and mounted on the horizontal magnetic poles (1), a current is applied by means of the magnet exciting coil (2), a steady-state magnetic field is generated between the horizontal magnetic poles (1) and the vertical magnetic poles (3); when passing through the steady-state magnetic field, the molten steel flowing in the crystallizer (7) receives an electromagnetic force opposite to the flowing direction of the molten steel, and the flow of the molten steel in the crystallizer is controlled by means of the electromagnetic force.
