Abstract :
This paper makes an industrial experimental study of the influence of crystal growth characteristics, crystal growth striations and rotating magnetic field on the growth characteristics of ingot cellular crystal in the production process of high purity aluminum by vertical high purity aluminum directional solidification equipment and hereby optimizes productive and technical parameters, thereby successfully producing 5N large-diameter high purity aluminum ingots whose purity is greater than 99.999%.
