SIMULATION OF MULTIPASS ZONE-REFINING PROCESSES

This study discusses the application of analog simulators to multipass zone-refining processes. The structure, operation, and mathematical r epresentation of none-refining simulators are discussed. The results o btained from the proposed zone-refining simulators are in excellent ag reement with analytical solutions. Furthermore, the simulators can als o be used to simulate zone-refining with different initial distrbution s of solute, variable distribution coefficient, and variable zone leng th along the ingot.
