A converter comprising a container (2) defining a first axis (X); a support ring (3), coaxial to the container (2) and spaced therefrom, equipped with two diametrically opposite supporting pins (6), defining a second axis (Y) which is orthogonal to the first axis (X), adapted to allow the converter to be rotated about said second axis; suspension elements, connecting said container (2) to said support ring (3), restrained at a first end to the container (2) and at a second end to the support ring (3); in which said suspension elements comprise at least three first bars (7) arranged parallel to the first axis (X) and substantially equidistant from each other along said support ring; at least two second bars (8, 8′), each second bar (8, 8′) being orthogonal to said second axis (Y) and diametrically opposite with respect to the other second bar (8′, 8); at least one third bar (9) being arranged parallel to a first plane (X-Y) defined by said first axis (X) and second axis (Y); wherein all said bars are fixed-end bars.
