Embodiment 1

[0044] like figure 1 , figure 2 As shown, an electromagnetic braking device for controlling the flow of molten steel in a tundish according to this embodiment includes a first yoke 100, a second yoke 200, and the first yoke 100 and the second yoke 200 are arranged opposite to the middle On both sides of the package, the first yoke 100 and the second yoke 200 are wound with electromagnetic coils, and two magnetic fields are generated between the first yoke 100 and the second yoke 200, and the directions of the two magnetic fields are both directed from one side. On the other side, the two magnetic fields brake the molten steel in the tundish twice. The electromagnetic braking device of this embodiment does not directly contact the molten steel. Compared with the prior art, it will not cause secondary pollution of the molten steel due to the erosion and corrosion of the turbulence controller or refractory materials such as dams and weirs by the molten steel. , The device gene...

Embodiment 2

[0069] like image 3 , Figure 4 As shown, an electromagnetic braking device for controlling the flow of molten steel in the tundish according to this embodiment is arranged on both sides of the single-flow tundish as the electromagnetic braking device for the single-flow tundish. Specifically, the device is vertically installed on the front and rear sides of the tundish, and is placed facing the impact zone 300. The two magnetic field directions are both directed from one side to the other, and both are parallel to the bottom of the tundish, and the range is determined by the long nozzle ( That is, the molten steel starts from the position where the ladle flows into the inflow port of the tundish). Since the height of the yoke is higher than that of the single-flow tundish, when the molten steel is poured from the ladle to the single-flow tundish, the molten steel vertically passes through the upper magnetic field from top to bottom at high speed, and the bottom-up electroma...

Embodiment 3

[0072] like Figure 5 , Image 6 As shown, an electromagnetic braking device for controlling the flow of molten steel in the tundish according to this embodiment is arranged on both sides of the double-flow tundish as an electromagnetic braking device for the double-flow tundish. Specifically, the device is installed vertically on the front and rear sides of the tundish, and is placed facing the impact zone 300. The two magnetic field directions are both directed from one side to the other side, and both are parallel to the bottom of the tundish. Location is the center. Since the height of the yoke is higher than the double-flow tundish, when the molten steel is poured from the ladle to the double-flow tundish, the molten steel vertically passes through the upper magnetic field from top to bottom at a high speed, and the generated bottom-up electromagnetic force is applied to the molten steel. A deceleration is caused. After the molten steel reaches the impact zone 300, it f...

Abstract

The invention discloses an electromagnetic braking device and method for controlling flowing of molten steel in a tundish, and belongs to the technical field of steel continuous casting production. The electromagnetic braking device comprises a first yoke and a second yoke, the first yoke and the second yoke are oppositely arranged on the two sides of a tundish, electromagnetic coils are wound around the first yoke and the second yoke, two magnetic fields are generated between the first yoke and the second yoke, the two magnetic fields point to the other side from one side, and the electromagnetic coils are wound around the first yoke and the second yoke. And the two paths of magnetic fields are used for braking the molten steel in the tundish twice. According to the electromagnetic braking device, the purposes of flow control and cleaning are achieved under the conditions that the electromagnetic braking device does not make direct contact with molten steel and does not occupy the effective volume in the tundish, and floating removal of inclusions is facilitated.

Description

technical field [0001] The invention belongs to the technical field of iron and steel continuous casting production, and more particularly relates to an electromagnetic braking device for controlling the flow of molten steel in a tundish. Background technique [0002] The flow phenomenon of molten steel in the tundish is of great significance to improve the quality of steel, which is determined by the design of the tundish and its flow control device. As the key link of the tundish affecting the composition of molten steel in the continuous casting process, in order to better play its role in controlling the flow and cleaning the molten steel, it is very important to study and improve the flow field in the tundish in metallurgical work. At present, the common tundish has various shapes, and the structure is a shell welded by steel plates, which is lined with a thermal insulation layer, a permanent layer and a working layer. The main function of the tundish is to stabilize t...
