| Abstract: | Under the condition of electromagnetic self constrained directional solidification, the response of temperature distribution to drawing rate and the effects of convection caused by electromagnetic stirring on temperature distribution and temperature gradient G L on the solid/liquid interface were explored. Influences of meniscus height and solid/liquid interface position on temperature distribution and G L were detected. Finally several effective ways to increase G L were obtained from the experimental results. |
