Abstract

Continuous casting of molten metal in a through-flow mould as in NL 6900739. The apparatus comprises a lower, solidification section and an upper, tubular insulating section which limits the heat loss from the molten metal in it. Heat is fed to the insulating section and a restricted passage between the upper and lower sections is formed. The inclusion of surface impurities of non-metallic materials, foam or slag is minimised.
