METHOD AND INSTALLATION FOR THE CONTINUOUS CASTING OF TUBULAR PRODUCTS

摘要

A method for continuously casting tubular metal produ??? particularly thin cast iron tubes. Metal is cast under pressure in the die, the metal in contact with the core of the die being kept in the liquid state so that a substantially frustoconical solidification front is created starting from a point of the wall of the mould close to the inlet of the die and leading virtually to the extreme edge of the core. The method may be implemented in an installation comprising a device for heating inside the core and, around the mould, a pressurised liquid metal jacket surrounded by a cooling water jacket. The core and the mould define a vertical annular die.
