ABSTRACT:
A process for continuous production of an extruded section, in particular of aluminum or an aluminum alloy, wherein a prefabricated rod is fed to a die by means of a friction wheel and extruded through the die. The rod is formed by casting the molten metal in an electromagnetic mold and the solidified rod fed directly to the friction wheel the circumference of which advances the rod at the same speed as the rate of casting of the rod in the electromagnetic mold. The process enables high quality extruded sections to be produced at a economic cost.
