Abstract
The process and the device according to the invention relate to the continuous casting of hollow bodies made of metals such as aluminum, copper, steels of all types or other metals or alloys. The process involves introducing the liquid metal into an annular space between an external mold and an internal mandrel, the liquid metal being subjected in the vicinity of the mandrel to the action of a moving magnetic field which drives it upward. This field is created by a magnetic rotor housed in the mandrel comprising a rotating part around which is arranged at least one spiral made of magnetized magnetic material made integral with the rotor by at least one collar. The process is applied, in particular, to the production of blanks intended for the manufacture of seamless tubes.
