Copper mould tube for CCM Cr-plating NiCr-coating NiFe-plating
Situated in a critical position of continuous casting machine,
copper mould requires extreme high thermal-conductivity and high
strength. The molten steel will be formed into a certain shaped
steel billets immediately after it passes through the copper mould.
Besides basic function of shaping and solidifying the steel strand,
copper mould is of great influence on the economics of continuous
casting lines.
Not only the cost, the service life of copper mould and the quality
of the cast product are also considered as important factors by the
users.
Therefore, suitable mould design as well as study of continuous
casters and working conditions is making stringent demands on the
manufacturers.
