Abstract
In the last three years, cold hearth melting and casting equipment with a total melting capacity of about 15 MW were procured or put in operation in USA and Japan. Further definitive projects of such plants will provide in the near future an additional melting power of the same magnitude. The plants are operating with the so-called ‘continuous flow’ or ‘cold hearth’ melting process, where the liquid metal is flowing from a water-cooled metallic trough into the casting metallic crucible. As heat sources, high power electron beam or plasma guns are used. This paper tries to introduce the present state of the art in this field from the view of a contributing equipment supplier.
