Abstract

In this paper, for ϕ800mm round billet vertical continuous casting process, a computational study of the effect of Final electromagnetic stirring (F-EMS) at positions (7.5 m, 9 m, 10.5 m and 12 m) from the meniscus of mold on fluid flow and heat transfer has been carried out. Considering the influence of the solidified shell thickness on magnetic field. The thicker the solidified shell, the smaller the magnetic induction intensity and electromagnetic force inside the billet. Once the position is shifted down by 1.5 m, the thickness of the solidified shell increases by about 21 mm and the magnetic induction intensity at the center of the billet decreases by about 6mT. According to the velocity and the 3-D streamline distribution, at the position 7.5 m from the meniscus of mold, the flow velocity is 0.01158 m·s−1 and part of the molten steel has an obvious upward recirculation zone. Moving the position from 9 to 10.5 m, the stirring range and flow velocity are reduced. The flow velocity is 0.00206 m·s−1 at the position 12 m from the meniscus of mold and the molten steel has no effective flow. Electromagnetic stirring accelerates the heat transfer and uniform temperature. It has a great effect on the core temperature, but a little effect on the solidified shell temperature. After adding F-EMS, the core temperature decreased by 2–5 K. As the position moves down from 7.5 to 12 m from the meniscus of mold, the radial length of the action range decreases from 0.13 to 0.03 m. The effective action range of uniform temperature is basically equal to the radial length of liquid fraction fl ≥ 0.7. The industrial experimental results show that adding F-EMS at 9.3 m away from the meniscus of mold can improve the porosity, crack and segregation to a certain extent.
