Description
Technical field
The utility model relates to a kind of tiltable converter, it has the backing ring that surrounds converter body apart, this backing ring has two radially opposed bearing journals, wherein converter body is supported on the backing ring by a plurality of web members, wherein a part of web member is made of stack of laminations, described stack of laminations is arranged on the bottom surface of backing ring with distributing, and described stack of laminations is fixed on backing ring and the converter body with its opposed end portion section.
Background technology
Converter is a kind of tilting-type metallurgical tank, can make and handle liquid metal and metal alloy in this container.This converter body will bear the high heat load that causes huge thermal expansion and distortion at run duration.Therefore backing ring surrounds converter body with predefined spacing.On at present general converter size, except heat load, additionally in web member, produce high mass loading, wherein this load changes with the position of fascinating of converter body.Therefore web member is arranged such that when converter body is in any one travel position, does not occur overload on single web member.In addition, web member should be positioned to the splash that prevents as far as possible from the slag of converter mouth.In order to satisfy these requirements as much as possible, from prior art the web member or the web member system that converter body is connected with backing ring of known a series of different embodiments.
A kind ofly known converter is suspended on the embodiment of the converter suspension system on the backing ring, comprises a plurality ofly circumferentially being arranged on the backing ring bottom surface and the lamination element that converter body is connected with backing ring.This suspension system form is known from DE 19 03 685 B2 and EP 1 061 138 B1.Known another kind of embodiment from DE 19 03 685 B2 promptly on the backing ring end face, along the circumferential direction seamlessly is assembled to the circumferential carriage of converter body between the bearing on the backing ring.Guarantee that with this converter body is bearing in the position of fascinating reliably.Though this solution allows circumferential carriage to move along radial direction,, will cause the power of enforcement that can cause bearing to crack with the deviation of the accurate circle of converter body or putting teeth in of circumferential carriage.The body of heater guide rail of the permission radial motion of known a kind of same function principle from EP106 113 8 B1, described body of heater guide rail constitutes by giving prominence to leading wall and leading the guide of seamlessly guiding in the wall on the backing ring top flange.
Known a kind of converter suspension system from DE 29 31 671 A1 though described converter suspension system becomes a reality the principle of above-mentioned lamination suspension system, has been used the connect elements of other structure formations.These connect elements are made of be articulated and connected pivotally the trilateral guide rod on backing ring and converter body or the bolt of distance variable adjusting.Because on the backing ring bottom surface and at backing ring end face upper edge circumference, arranging a plurality of connect elements with all distributing, to produce the installation costs that increases when changing converter, the replacing of described converter is owing to additionally become difficult because of staining with the fire door slagging scorification of causing of slag or steel knurl on the connect elements that is arranged on the backing ring end face.
The converter suspension system that known a kind of system that is made up of trilateral guide rod and fork constitutes from DE 27 39 540 A1, described converter suspension system is arranged on backing ring end face and the bottom surface with distributing and backing ring and converter body is articulated and connected.Wherein connect elements is arranged such that not only the vertical blowing position in converter, and in each position of fascinating, can both guarantee converter load sharing and supporting as far as possible uniformly.In the improvement project of this known embodiment, known, all connect elements from DE 43 27 640 A1, is constructed to fork and is disposed in the zone that prevents steel knurl infringement on the backing ring bottom surface by preferred 6 or 7.This embodiment is by being suspended on converter body still the solution that present best converter suspension system is provided on the backing ring.
Known a kind of converter suspension system from DE 33 41 824 A1, on described converter suspension system, converter body is bearing in the removable hollow supporting on the resting support hangingly with its bearing journal.The pre-tensioned flexible tensioning member that is parallel to converter medullary ray layout connects hollow supporting and resting support.General for this reason localized crosswise fixed tensioning member is bearing in converter the belly position and bears pulling force.On all positions of fascinating between vertical converter position and the belly position, not only tensioning member, and crosswise fixed tensioning member all can bear undesirable stress in bending.
The utility model content
The purpose of this utility model is shortcoming and a difficult point of avoiding above-mentioned, and a task proposed, the advantage of converter that the tiltable converter that promptly provides this paper to start described form, described tiltable converter will have the lamination suspension system of known radial flexibility combines with the advantage of the known fork suspension system that is configured to VAI-CON Link suspension system.
According to the utility model, described task is so to solve, and promptly as to the replenishing of the web member that is made of stack of laminations, another part web member is made of fork, and described fork one end and backing ring are articulated and connected, and the other end and converter body are articulated and connected.
Each one stack of laminations comprises at least two mutually apart laminations each other, when converter body is vertically erect, described lamination be rigidly fixed to be positioned on the backing ring bottom surface and converter body on frame support bracket on.The location of stack of laminations and orientation realize on the bus of imaginary conical surface, and the vertical axis of described conical surface is equivalent to the converter axis and its bus is assembled downwards.This layout allows converter to do radial motion in backing ring.Additional fork bear fascinate between moving period and the position of fascinating on the radial force that occurs, and converter body is supported on the backing ring.Wherein fork can be arranged on the end face or bottom surface of backing ring, perhaps also can be arranged on two sides of backing ring.Another advantage of lamination suspension system and the combination of fork suspension system is that compare with the similar converter suspension system that only is made of fork, fork only need bear littler power here.
If with fork in each bearing journal zone, be roughly parallel to the plane that constitutes by backing ring and be approximately perpendicular to converter body by the axis that fascinates that bearing journal constituted, be arranged on the end face and bottom surface of backing ring, especially can obtain these advantages.According to the direction of fascinating, pulling force or pressure are transmitted to fork.
According to a kind of special embodiment, fork is fixed in the zone on backing ring and the converter body, and described zone is along forming the space between the stack of laminations at direct neighbor in the vertical projection of converter axis direction.
In order to reach the purpose that makes web member as much as possible prevent the fire door slagging scorification, fork is being arranged between the stack of laminations of direct neighbor on the bottom surface of backing ring.
Two fork one ends and backing ring are articulated and connected, and the other end and converter body are articulated and connected.
For the space motion that guarantees fork and avoid importing bending force, fork hingedly is fixed on backing ring and the converter body by means of globe bearing.
