Abstract
The invention relates to a steel-liquid flow-field dynamic control device used for a casting steel crystallizer. The invention comprises two separated magnetic yokes and two magnetic pole groups which are respectively arranged at the outer side of the copper plate of the steel crystallizer. One end of the magnetic pole group firmly contacts the magnetic yoke to form a closed loop. A plurality of magnetic poles are fixed to form magnetic pole groups by two coil frames and the outer wall is winded with the coil. The other end of the magnetic pole group is contacted with the copper plate of the steel crystallizer to form a static magnetic filed between the magnetic pole groups. The invention can control and optimize the steel liquid flow field in the steel crystallizer through regulating the magnetic field strength of different positions on the width of the steel crystallizer or changing the opposite position between the magnetic poles and an invaded water gap, meeting the requirements of high speed, high efficiency and high cast-blank quality.

According to above-mentioned inventive concept, the present invention adopts following technical proposals:
Flow field of molten steel device for controlling dynamically in a kind of continuous cast mold, yoke and two magnetic pole groups of comprising two separation that place the copper plate of crystallizer outside respectively, it is characterized in that each magnetic pole group forms the outer wall winding around of described coil former by a coil former with a plurality of magnetic poles are fixing; One end of each magnetic pole group closely contacts with yoke, produces the closed-loop path, and its other end contacts with copper plate of crystallizer, produces magnetostatic field between the magnetic pole group; A monitoring device that is inserted in the flow field of molten steel is arranged, be used to monitor temperature or the flow velocity of molten steel face or the thickness of liquid slag layer of molten steel in the crystallizer; A signal input/output unit is arranged, connect monitoring device and receive the data-signal of monitoring device by cable, and, connect a hydraulic means of control and a lowering or hoisting gear by cable according to the described data-signal that receives; Hydraulic means produces different magnetostatic field or the identical magnetostatic fields of intensity of intensity in order to change distance between two poles on the width of copper plate of crystallizer; Lowering or hoisting gear is in order to regulate the relative position of magnetic pole and submersed nozzle outlet.
Each above-mentioned magnetic pole group is arranged on the whole width of copper plate of crystallizer, according to the width of copper plate of crystallizer, changes the size of every magnetic pole and the piece number of magnetic pole.
The present invention has following conspicuous outstanding substantive distinguishing features and remarkable advantage compared with prior art:
Pass through temperature or the flow velocity of molten steel face or the thickness of liquid slag layer of molten steel in the monitoring crystallizer among the present invention, dynamically adjust the magnetic field intensity of diverse location on the crystallizer width and the relative position of change magnetic pole and submersed nozzle, thereby realize dynamically control in the casting process and optimize flow field of molten steel in the crystallizer, satisfy at a high speed, the requirement of efficient and high slab quality.
