Abstract
Abstract A supporting ring for metallurgical vessel, such as a tiltable or revolvable steel mill converter, includes straps secured around the periphery of the vessel and in heat exchange relation therewith. These straps are connected to a support ring for the vessel, which also surrounds the vessel but is not in heat exchange contact therewith. The supporting arrangement includes adjustable connecting screws which have a hinge-like connection at one end to the supporting ring, for displacement in at least a radial plane, and the other ends of which screws are hingedly connected to the projections of the vessel shell or wall, such as projections on the straps.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
242 words
A supporting arrangement for vessels used in metallurgical processing involving heat, such as tiltable, revolvable and tiltable and revolvable steelmill converters, of the type in which the vessel is supported in at least one supporting ring, said supporting arrangement comprising, in combination, support elements secured on the vessel wall and supporting the vessel on at least one axial end face of a supporting ring when the vessel is in an upright position; at least one first apertured projection member on the associated supporting ring; at least one second apertured projection member on the vessel wall; the apertures of associated first and second projection members being substantially aligned; respective tension rods extending through the apertures of associated first and second projection members and projecting beyond the two associated member, fastening means on the projecting ends of each rod cooperable with the two associated projection members to prestress the respective rods in tension when said vessel is in said upright position; and bearing means on the opposite projecting ends of each tension rod and engaged at least between the adjacent projection member and the adjacent fastening means to transmit tension stresses of the associated tension rod; said tension rods extending in a direction to suspend the vessel from the supporting ring when the vessel is tilted to at least the horizontal position; said bearing means providing for swinging displacement of the associated tension rods in a radial plane of the supported and tilted vessel.
Claim 2
Dependent Claim
242 words
A supporting arrangement for vessels used in metallurgical processing involving heat, such as tiltable, revolvable and tiltable and revolvable steelmill converters, of the type in which the vessel is supported in at least one supporting ring, said supporting arrangement comprising, in combination, support elements secured on the vessel wall and supporting the vessel on at least one axial end face of a supporting ring when the vessel is in an upright position; at least one first apertured projection member on the associated supporting ring; at least one second apertured projection member on the vessel wall; the apertures of associated first and second projection members being substantially aligned; respective tension rods extending through the apertures of associated first and second projection members and projecting beyond the two associated member, fastening means on the projecting ends of each rod cooperable with the two associated projection members to prestress the respective rods in tension when said vessel is in said upright position; and bearing means on the opposite projecting ends of each tension rod and engaged at least between the adjacent projection member and the adjacent fastening means to transmit tension stresses of the associated tension rod; said tension rods extending in a direction to suspend the vessel from the supporting ring when the vessel is tilted to at least the horizontal position; said bearing means providing for swinging displacement of the associated tension rods in a radial plane of the supported and tilted vessel.
Claim 3
Dependent Claim
30 words
