Description
Summary:A mercury model has been developed to investigate the influences of Electromagnetic Mold Brake Ruler(EMBr-Ruler)and Flow Control Mold(FC Mold)on metal flow in slab continuous casting mold with the practical casting speed 1.0,1.3 and 2.0 m/min respectively.FC-Mold can efficiently repress the surface flow and its fluctuation.The expanding space of the jets is compressed by EMBr-Ruler and FC-Mold respectively,then the"flow passage"where the vertical velocity of flow increases sharply is developed near the narrow wall with EMBr-Ruler and FC-Mold.It is bad for the development of the plug like flow.Only the nozzle ports are placed in the braking magnetic field region and the casting speed is suitable,EMBr can be beneficial to the formation of the plug like flow.The flow regime is improved with FC Mold when the casting speed is high(2.0 m/min),but EMBr can improve the flow field with medium casting speed(1.3m/min),but when the casting speed is low(1.0 m/min),the effects of two types of EMBr are both unsatisfactory.
