A combined feed tube and continuous casting mould comprises a copper mould having a refractory feed tube projecting into the inlet end of the mould passage. The feed tube is in abutting relation with the wall of the mould passage and the material from which the feed tube is formed is one which has a low coefficient of friction such as graphite. The portion of the feed tube in the mould provides the surface on which the initial freezing of the molten metal occurs and this surface is cooled by its contact with the mould.
