Abstract
A plant for metallization of a metal pipe obtained by upward vertical continuous casting and displaced vertically in a continuous manner, includes, along the path of the pipe, a metallization station having a passage for the pipe, a metallization enclosure (6), spray guns (11) mounted inside the enclosure on an oscillating plate (10) surrounding the path, means for supplying each gun with metallization material (12), and a device for causing oscillation of the support plate and for displacing the guns inside the enclosure with an oscillating movement, the frequency and angular amplitude of which ensure the formation of a coating of uniform thickness.
