Abstract:The electron beam cold hearth melting (EBCHM) technology has been widely used due to the technical advantages of eliminating high-density inclusions and low cost. According to the technology feature of EBCHM and integrating the productive practice, the advantages and limitations of EBCHM were discussed. Some ideas and references for optimizing the melting techniques and producing the best titanium and titanium alloy ingots based on EBCHM technology which is reasonably applied were provided.
Key words: electron beam cold hearth melting (EBCHM); melting; metallurgical quality
