Abstract：The flow field and temperature field in bloom continuous casting mold with electromagnetic stirring were simulated by numerical method. The effect of the stirring intensity on flow and temperature fields was analyzed. The results show that the molten steel flows distributes circumferentially in the horizontal plane. and the molten steel flowing from submerged entry nozzle collides with the upward recirculation flow in the strand direction. With the decrease of immerged stream depth, the axial temperature decreases rapidly, and the radial temperature increases which will improve the heat transfer of molten steel in mold. The greater the stirring intensity, the more prominent the secondary flow phenomena is and the higher the position of hot area is.
