Abstract

Abstract:

Based on the redistribution model of solutes for multi-zone refining, zone lengths were optimized to minimize the content of solute in the middle of the sample using a genetic algorithm from biological evolutionary theory. The redistribution of solute in the sample during multi-zone refining was computed with the optimized zone length and a constant zone length. The calculation results showed that the efficiency of zone refining with the optimized zone length was significantly better than that with the constant zone length. A low impurity concentration in the 80% part of the middle sample can be achieved after 15 passes of zone refining using the optimized zone lengths.

Key words: Redistribution model of solute, Genetic algorithm, Optimization, Molten zone length, Redistribution of solute
