PROCEDEU SI INSTALATIE PENTRU TURNAREA CONTINUA A PRODUSELOR TUBULARE

摘要

The process is particularly intended for the casting of thin tubes of iron in a vertical annular die defined by a mould and a core. It comprises maintaining in the liquid state metal under pressure poured into the die and in contact with the core so as to create a substantially frustoconical solidification front which extends from a point of the wall of the mould in the vicinity of the input end of the die and reaches practically the lower end edge of the core. The installation for carrying out this process comprises a heating device inside the core and a liquid metal jacket under pressure which surrounds the mould and is surrounded by a water cooling jacket.
