| Abstract: | By regression analysis of the obtained data, a relationship has been found between the bath depth and ingot height, which can be expressed by an exponential function. This model can be used to describe and predict the most bath depth at any current and the variation tendency of the bath depth with the increase of ingot height. The bath depth influences the direction of crystal growth, nonmetallic inclusion removal, and the degassing process. Proper control of the re-melting current and bath depth will do good to the structure and the quality of ESR ingot. |
