SUSPENSION DEVICE FOR TILTING OXYGEN CONVERTERS AND CONVERTER PROVIDED WITH SAID SUSPENSION DEVICE

摘要

A suspension device (8) for a converter, comprising a central structure (8′), adapted to be fixed to a container (2) of the converter (1), a first lateral structure (29), arranged at a first side of the central structure and adapted to be fixed to a first surface (10, 11) of a supporting ring (3) of the container, a second lateral structure (28), arranged at a second side of said central structure and adapted to be fixed to the surface (10, 11), wherein two wedge-shaped elements (15, 15′) are provided, each element being provided between the central structure and a respective lateral structure and configured so as to slide on sliding surfaces (23, 24, 24′) connected respectively to the central structure and to the respective lateral structure, wherein each wedge-shaped element is crossed by at least one tie-rod (16, 16′) connected thereto, and wherein elastic means (17) are provided, which are associated to or intrinsic with said one tie-rod and configured to maintain a wedging of the wedge-shaped element.

1. A suspension device for a tilting converter, comprising:
a central structure, adapted to be fixed to a container of the converter, a first lateral structure, arranged at a first side of said central structure and adapted to be fixed to a first surface of a supporting ring of the container, a second lateral structure, arranged at a second side of said central structure, opposite said first side, and adapted to be fixed to said first surface of the supporting ring, wherein two wedge-shaped elements are provided, each wedge-shaped element being arranged between the central structure and a respective lateral structure and configured so as to slide on two sliding surfaces of the central structure and of the respective lateral structure, respectively, wherein each wedge-shaped element is crossed by at least one tie-rod connected thereto, and wherein elastic means associated to said at least one tie-rod or wherein said at least one tie-rod with its intrinsic elasticity are configured to produce a constant wedging of the wedge-shaped element whereby, when the suspension device is mounted to the container and to the supporting ring, an automatic adjustment of the suspension device occurs as the expansions produced between central structure and lateral structures vary during the operation of the converter.
