Abstract

A tilting converter comprising a container ( 2 ), defining a first longitudinal axis X, having a bottom ( 2 ′); a support ring ( 3 ), coaxial to the container ( 2 ) and distanced from said container, provided with two diametrically opposite supporting pins ( 6 ), defining a second axis Y orthogonal to the first axis X, adapted to allow a rotation of the converter about said second axis Y; a suspension system, connecting said container ( 2 ) to said support ring ( 3 ), comprising groups ( 12 ) of first suspension devices ( 7 ), said groups ( 12 ) being arranged substantially equidistant to each other along a cylindrical side surface coaxial to the first axis X, in a position between the support ring ( 3 ) and the bottom ( 2 ′); each of said first suspension devices ( 7 ) being provided with a plurality of longitudinal elastic elements, each longitudinal elastic element being arranged alongside the next so as to define a laying plane, and a gap ( 15, 15 ′) is provided between one longitudinal elastic element and the next.

First claim

What is claimed is:

1. A tilting converter comprising:
a container, defining a first longitudinal axis X, having a bottom;
a support ring, coaxial to the container and distanced from said container, provided with two diametrically opposite supporting pins, defining a second axis Y orthogonal to the first axis X, adapted to allow a rotation of the converter about said second axis Y;
a suspension system, connecting said container to said support ring, comprising groups of first suspension devices, said groups being arranged substantially equidistant to each other at a cylindrical side surface coaxial to the first axis X, in a position between the support ring and the bottom,
characterised in that each of said first suspension devices is provided with a plurality of longitudinal elastic elements rigidly connected by means of their opposing ends to the container and to the support ring respectively, each longitudinal elastic element being arranged alongside the next so as to define a single laying plane for each of said first suspension devices of each group, and a gap is provided between one longitudinal elastic element and the next one in each of said suspension devices of each group;
wherein the gap between a longitudinal elastic element and the next is defined by a longitudinal notch passing through the thickness of a flat plate defined by the union of said longitudinal elastic elements arranged alongside, the longitudinal notches being obtained in a central area of said flat plate.

2. A converter according to claim 1 , wherein, in each group, the laying plane defined by the plurality of longitudinal elastic elements of one suspension device of said first suspension devices is different from the laying plane defined by the plurality of longitudinal elastic elements of another suspension device of said first suspension devices.

3. A converter according to claim 1 , wherein each of said first suspension devices is parallel to the first axis X and tangential to said cylindrical side surface.

4. A converter according to claim 3 , wherein said longitudinal elastic elements are parallel to the first axis X.

5. A converter according to claim 1 , wherein each of said first suspension devices ( 7 ) is inclined with respect to the first axis X.

6. A converter according to claim 5 , wherein said longitudinal elastic elements are inclined with respect to the first axis X.

7. A converter according to claim 1 , wherein said first suspension devices are restrained at a first end to the container and at a second end to the support ring, preferably by means of locking on respective fastening supports.

8. A converter according to claim 7 , wherein all the longitudinal elastic elements of each of said first suspension devices are together rigidly connected by means of a first single fastening support to the support ring and by means of a second single fastening support to the container.

9. A converter according to claim 7 , wherein a first fastening support to the support ring is integral with a first surface of the support ring, facing the bottom of the container.

10. A converter according to claim 1 , wherein each flat plate is provided with a circular hole at each end of the longitudinal notches.

11. A converter according to claim 10 , wherein the circular holes communicate with the respective longitudinal notch and, preferably, have a diameter equal to a value at least ten times the width of the longitudinal notches.
