Copper mould tube is the heart of the continuous casting machine,
the main function of the mould is to establish a solid shell
sufficient in strength to support its liquid core upon entry into
the secondary spray cooling zone. The mould is basically an
open-end box structure, containing a water-cooled inner lining
fabricated from a high purity copper alloy. The inner face of the
copper mold is often plated with chromium or nickel to provide a
harder working surface, and to avoid copper pickup on the surface
of the cast strand, which can otherwise facilitate surface cracks
on the product.
