A specialised steel making process in which a
rolled or a cast ingot in the form of an electrode
is remelted in a water cooled copper mold. The
melting is activated by resistive heat generated
in a conductive slag. The resulting product has a
similar basic chemical composition to the original
ingot, but is characterised by high purity and low
inclusion content. Typical applications include
high integrity components for the aerospace
industry.
