Abstract
ABSTRACT A 3D mathematical model of 180 mm × 220 mm billet continuous casting process has been established, which includes electromagnetic field, flow field, solidification and solute transport, and the effect of stirrer position on multiple physical fields distribution is investigated. The results show that, when the stirrer centre positions are located at Y = 515 mm, Y = 615 mm and Y = 715 mm, the growth of the solid shell near the stirrer centre slows down. And the solid shell is remelted and thinned at the mould exit for the stirrer centre position placed at Y = 815 mm. As the stirrer centre position is lowered, the carbon concentration at the mould top reduces gradually. Furthermore, when the stirrer centre position is moved from Y = 515 mm to Y = 815 mm, the carbon concentration on the surface of billet reduces from 0.00211 to 0.00197.
