Description
Technical field
The utility model relates to a kind of converter of fascinating, this converter has the sustained ring that converter shell is surrounded with spacing, it has the supporting gudgeon of two diametrically contrapositions, and wherein said converter shell is fixed on described sustained ring with a plurality of connect elements and connect elements is rigidly fixed on the one hand on the bottom surface of described sustained ring and is rigidly fixed on the other hand on described converter shell with its opposed end respectively.
Converter be the container of the metallurgy that can fascinate together with suspension, make and process liquid metal and metal alloy in the container of described metallurgy.These converter shells stand higher thermal load in the process of operation, described thermal load causes very large thermal expansion and distortion.Therefore, sustained ring surrounds described converter shell with predetermined spacing.For common now converter size, higher weight loading also appears in connect elements except thermal load extraly, and wherein these loads fluctuate according to the obliquity of described converter shell.Therefore should so arrange described connect elements, thereby can overload not occur on single connect elements in any travel position of described converter shell.In addition, described connect elements should be arranged from the mode of the impact of the slag splash of converter mouth preventing to a great extent being subject to.
Background technology
In order to meet to a great extent these requirements, the system that discloses a series of connect elements that converter shell and sustained ring are coupled together or consisted of by the connect elements of different embodiments from prior art.
In a kind of embodiment of described connect elements, these connect elements are configured to the thin slice group, that is to say, it in most of the cases comprises two or three thin slices as such as comprising a plurality of apart thin slices each other shown in AT 504 664 B1.Be provided with a large amount of thin sheet element at this, described thin sheet element is arranged on circumference and with described converter shell and described sustained ring on the bottom surface of described sustained ring with distributing and couples together.This suspension is also disclosed from EP 1 061 138 A2.The advantage of described suspensions is that it is flexible diametrically.
The plate of the thin rectangle that described thin slice great majority are configured to be formed from steel.By its less thickness, it is easy to bending, only produces thus less stress when the thermal distortion of described converter shell occurring in described thin slice.The layout of the thin slice of group formula should be distributed to the load of described converter shell on larger cross section on the one hand, and the failure conditions if there is single thin slice should provide security on the other hand.The connection that produces by thin slice is representing uncertain system aspect static, that is to say that the stress that occurs in single sheet depends on the distortion of the described total system that is made of converter shell, sustained ring and thin slice group.The numerical analysis that the converter of in the past making is carried out clearly illustrates that, load between the thin slice of different groups, but also between the thin slice of a group, and even at the very big difference that is distributed with of the inside of a thin slice.That is to say, local stress concentration phenomenon can occur, the stress concentration phenomenon of described part greatly reduces the work-ing life of described thin slice.
The reason that differentiated load distributes has different causes.The layout of first precoordinate thin slice make more near the thin slice of the converter shell of heat namely the thin slice of the inside degree that obtains heating obviously greater than the thin slice of the outside of being covered by the thin slice of described the inside.The thin slice of the inside occurs to expand greatly and only bears the part of converter load or extraly to the thin slice loading of described outside thus.
Secondly, if the converter of having loaded is upright (0 ° of position just in time, the opening upwards of described converter shell) or (the 180 ° of positions of standing upside down, Open Side Down in described converter), so described sustained ring just deforms under the load of converter shell, because described sustained ring is bent downwardly with the spacing to the increase of described supporting gudgeon.Therefore thin slice group near the supporting gudgeon bears than those large loads of thin slice further from the supporting gudgeon.
The part that described thin slice group is born described load equally when charging and tapping at last, wherein tilted in charging and the described converter of when tapping+90 ° or-90 °, although converter shell described here mainly is supported on described sustained ring by the link of extra element such as backstop or level.But, be in the width in the scope of hundreds of millimeters and the shear rigidity that is associated therewith due to described thin slice larger, described thin slice bears the part of the load of described converter shell in this case.Shear loading occurs thus and extremely inhomogeneous stress distribution or local stress concentration phenomenon occur in described thin slice in described thin slice and fixed sturcture thereof.
The utility model content
Therefore, task of the present utility model is, a kind of converter of fascinating is provided, and comes distributed load in described connect elements more equably with this converter.
This task solves in the following manner; be that described connect elements just comprises a thin slice; this thin slice covers with protecting component with respect to described converter shell; described protecting component equally not only is connected with described converter shell but also is connected with described sustained ring with its opposed end, but the only end in these ends is rigidly connected with described sustained ring or with described converter shell.
Only be provided with the thin slice of a supporting for each connect elements, all thin slices of all connect elements stand identical condition basically about the thermal radiation of described converter shell.Therefore the differentiated distribution of the load between a plurality of thin slices of connect elements appears never again.
As thin slice, typically refer to the element on the namely plane of thin, narrow and sheet.That is to say, the width of described thin slice than its thickness large manyfold and its width of its Length Ratio is large on the other hand manyfold.The size that has typical 5-20mm thickness, 200-600mm width and 1000-2000mm length by thin slice of the present utility model.
Described thin slice is usually so directed, makes the plane parallel of described thin slice stretch in the tangent plane of described converter, and this is just as the situation of pressing on the thin slice group of prior art.Described thin slice stretches in the mode in the several years of tilting with respect to vertical line, if above the opening of described converter shell is in.
The fixing of rigidity of being connected with sustained ring at converter shell of described thin slice can be threaded connection, sell connection or be welded to connect to carry out.
By the described protecting component that there is no the function of supporting itself, unique thin slice obtains better protecting to prevent the heat of described converter shell now, thereby the degrees of expansion of present described thin slice is not too violent.This causes the raising of the serviceability of longer work-ing life of described thin slice and described suspension.
Because described protecting component does not have the function of supporting; so another of described protecting component-be not that rigidly connected-end is connected with described sustained ring or described converter shell along the longitudinal direction with the gap, be used for allowing described protecting component-along its longitudinal direction-thermal expansion freely.
Another of described protecting component-not that rigidly connected-end can be connected with described sustained ring or described converter shell by means of the mechanism of blocking (Fangsicherung), make described protecting component can bear its load when described thin slice loses efficacy.
In order to guarantee the thermal protection effect as well as possible of described thin slice, can stipulate, described protecting component has the thickness larger than described thin slice.Described protecting component is such as the twice to three that is described thin slice is times thick for this reason.
In order to guarantee the thermal protection effect as well as possible of whole thin slice, can stipulate, described protecting component has length and the width of described thin slice at least.Whole thin slice is protected to prevent the direct thermal radiation from converter shell thus.Described protecting component this and described thin slice be arranged on the front of described thin slice superimposedly and be arranged on thus described thin slice and described converter shell between.
A kind of possible embodiment regulation, described protecting component is arranged in the capable mode in described thin slice of at least part of Horizon.If protecting component and thin slice are such as stretching in parallel with each other in the zone of its fixed sturcture, that just can be easily-such as by means of spacing pad-be fixed in identical stationary installation.
More be evenly distributed in order to load described be arranged on circumference by between thin slice of the present utility model, can stipulate, described connect elements is arranged in as close as possible described supporting gudgeon or described sustained ring to be used for the opening of supporting gudgeon.Described connect elements can only be arranged abreast rather than up and down with stacking.Therefore preferably it directly be arranged in the following of described supporting gudgeon and continue with to the as far as possible little pitch arrangement of these thin slices left side and the right at described thin slice.The lamellated connect elements of tool has been arranged respectively on the left side and the right of the vertical axis that passes such as in the opening from described supporting gudgeon or described sustained ring (the support pad axis suspension is at this) at this on the bottom surface of described sustained ring and and then another connect elements is also arranged respectively on the left and the right.
If described connect elements all is arranged near described supporting gudgeon, that just must arrange extra being used at the element that is just tilting or the position of negative 90 ° (in charging or tapping time) supported the load of described converter shell, the namely link of level above-mentioned or backstop.In this case, especially more closely being arranged in connect elements on described supporting gudgeon constructs widelyr than the connect elements of adjacent other.Thereby described thin slice can be provided with different width, is used for making the load distribution homogenizing between described thin slice.
For in the inclination of described converter shell just or in the position of negative 90 ° with the load reduction that causes by shearing of described thin slice to bottom line, such as method that can be by the numeral shape to described thin slice is optimized.The stress of the maximum in described thin slice is reduced to bottom line, and method is to make along the nominal rigidity of main direction (longitudinal direction) maximize and shear rigidity is minimized.This can advantageously realize in the following manner, and namely described thin slice attenuates towards the center from its opposed end.
Not only in the situation that described thin slice attenuates in the center can stipulate, described thin slice not only all is configured to symmetrical structure about its longitudinal center line but also about the lateral axis at its center.In the situation that described thin slice attenuates, this means, the described profile that attenuates is not only symmetrical about longitudinal center line on two longitudinal side of described thin slice, and be symmetrical about the lateral axis at center, thereby the distance of two ends leaving described thin slice of the described structure that attenuates equates and the described structure that attenuates is identical.Described thin slice is also superimposed with self again in the plane at described thin slice when having rotated 180 ° in this case.
But described thin slice not necessarily is configured to symmetrical structure, but it also can so consist of, and makes it in the situation that there is no the symmetrical double rotational symmetry that only has about its longitudinal center line or lateral axis.Described thin slice is such as can only tapering to the contact pin with identical width in zone therebetween, and the longitudinal edge in the zone that this contact pin never attenuates stretches towards the longitudinal edge that does not attenuate on another end of described thin slice.
But such " asymmetric " thin slice can be arranged in couples with being mutually symmetrical, especially arranges symmetrically about the vertical axis that passes from described opening for supporting gudgeon.
Press the utility model; only bear load and described protecting component as anti-warmware and as this mode of urgent fixed mechanism (Notsicherung) by described thin slice; with functional separation, each parts in described two parts are optimized for its function thus.Thereby occurring in described thin slice as at the stress that causes due to differentiated thermal expansion by the inside of the thin slice group of prior art.Described thin slice, protecting component and fixed sturcture (great majority are to be threaded) can more easily and with lower one-tenth design thus originally.In addition, improve thus preventing the reliability that lost efficacy and improving its work-ing life of described converter suspension.
By described thin slice being arranged near this mode described supporting gudgeon, realize the distributing more uniformly of load between described thin slice.The load of the maximum in described thin slice is reduced thus.This improves reliability and the work-ing life of described converter suspension on the one hand, and described thin slice can more easily and with lower one-tenth consist of originally on the other hand.
The stiffness characteristics that optimization by described lamella shape so affects described thin slice is shear rigidity and rigidity along the longitudinal direction namely, thus reduce significantly in described thin slice and described fixed sturcture in the stress of the maximum that occurs when charging or tapping.This same work-ing life and described thin slice that improves described converter suspension can more easily and with lower one-tenth consist of originally.
