Electrode manufacture for the remelting processes

The remelting processes require an electrode which has been made by conventional melting and casting. In this paper, we examine the relation between the electrode manufacturing process and the quality of the remelted ingot which has been made from it. We conclude that the quality of the electrode with respect to segregation, porosity, stress condition and content of non-metallic inclusions is critical to the quality of the remelted ingot. Specific examples of these aspects are presented. It is recommended that the electrode preparation process should be constructed following the specific requirements of the remelting process.
