Abstract

Furnace (1) for the heat treatment of elongated metal draw pieces (2) including a chamber (3), having an inlet (5) and an outlet (6), heating means (32) of the chamber (3), displacement means (20,120) for transporting the draw pieces (2), in turn moved thanks to actuation means (25) and control means for adjusting the functioning of the furnace (1) itself. In particular, the displacement means (20,120) displace the draw pieces (2) in a direction parallel to their longitudinal extension in the two directions. The furnace may comprise multiple height levels, parallel insulated heating chambers and charging/discharging elevators.
