Description
Technical Field
The invention relates to the field of metallurgy, in particular to a converter self-adaptive hanging structure.
Background
The suspension system is one of the key parts of the converter, and in practice, a trunnion ring in the suspension system is positioned outside the converter body through different types of suspension structures to realize the support of the converter body. When the furnace body is in operation, the tilting moment is applied to the trunnion of the trunnion ring, so that the moment is transmitted to the furnace body from the trunnion ring, and meanwhile, the trunnion ring absorbs various stress and form changes of the furnace body caused by temperature changes.
However, the technical difficulty of the suspension support system under the converter is the horizontal support of the converter in a non-vertical working posture, particularly the horizontal support structure and arrangement of the link mechanism and the operation of the converter, and particularly the direct influence on the operation safety and the operation quality (whether the converter tilts stably, whether impact, vibration, abrasion and abnormal sound exist, the safety margin of the converter equipment and the like) when the tonnage of the converter is large, and the core technical idea of the horizontal support of the link mechanism is the number of the link mechanisms and the positions of the link mechanisms arranged on the converter equipment.
Theoretical analysis and engineering practice prove that no matter what suspension structure is adopted, when the converter works and tilts and rotates, under the conditions of frequent impact of huge braking inertial mechanical force during forward and reverse rotation starting and stopping and deformation of high-heat-load equipment, alternating dislocation displacement can be generated between the furnace body and the trunnion ring body, including the alternating dislocation quantity caused by the bending and twisting action of the trunnion ring when the converter tilts and the alternating dislocation displacement generated between the furnace body and the trunnion ring body due to equipment structure, motion inertia, thermal expansion difference and the like, so that a plurality of suspension structures have certain adaptive deformation capacity to adapt to the alternating dislocation displacement.
In patent ZL93117357.4 invention patent "tilting converter", a plurality of link mechanisms are arranged between the lower part of the trunnion ring and the converter body, the types of the link mechanisms are two, namely a vertical link mechanism and a horizontal link mechanism, the horizontal link mechanisms are three groups, except that a pendulum bar 7 static guide mechanism is arranged in the middle part below the trunnion ring of the converter, 1 horizontal pendulum bar is arranged at the weak part of each side trunnion horizontal support below the trunnion ring of the converter, and engineering practice proves that: the 1 horizontal swing rod is arranged at the lug shaft end of each side, which is not beneficial to adapting to the working condition of a large-tonnage converter, when the converter is in a vertical working posture with a furnace mouth facing upwards, the stress is mainly concentrated on the vertical link mechanism, the vertical link mechanism can act in a self-adaptive manner, and when the converter is in a non-vertical working posture, the stress is mainly concentrated on the horizontal link mechanism, and the horizontal link mechanism can also act in a self-adaptive manner according to the stress. However, finite element analysis and engineering practice prove that in the converter, under two postures of erecting and inverting the converter, the bending and twisting action of the horizontal link mechanism at the installation part close to the lower part of the trunnion ring is most obvious, the 'alternating dislocation amount' at the part is obviously increased in the whole converter tilting and rotating process and is close to 7-13 mm, the actual engineering measurement data is up to 15mm at most, although the link mechanism can absorb partial relative displacement through self-adaptive action, the dislocation displacement amount at the part is large and is alternating dislocation impact displacement, the horizontal link mechanism cannot absorb all relative displacement, and not only the working principle working condition of the horizontal link rod piece only under tension pressure is influenced to a certain extent, but also the working life of the horizontal link mechanism is influenced, and the engineering practice proves that: this tilting converter horizontal support structure and arrangement is an inherent "short slab" in the design.
In the invention patent ZL201210291941.6, a four-point connecting rod hanging device arrangement structure of a converter, wherein four vertical connecting rod mechanisms are arranged between the lower edge of a backing ring and a converter shell, and a baffle seat mechanism is arranged between the upper edge of the backing ring and the converter shell, the vertical connecting rod mechanism in the scheme also has certain self-adaptive deformation capability, however, as long as the converter is provided with the baffle seat mechanism, no matter the baffle seat mechanism is arranged at any position of converter equipment, alternating elastic sliding exists between a converter shell baffle seat and a backing ring supporting seat, friction and abrasion can be caused, and a gap between the converter shell baffle seat and the backing ring supporting seat is generated and caused, when the strong inertia positive and negative rotation of the converter is braked, strong impact and sound can be generated, even the baffle seat falls off due to impact, equipment and personal safety hazards can be necessarily caused when the converter runs, therefore, the baffle seat device must be maintained and abraded parts must be replaced, although the proposal disclosed in the patent indicates that the replaceable antifriction cushion block is arranged between the furnace shell baffle seat and the backing ring support seat, the proposal means that the antifriction cushion block is connected with the baffle seat or the support seat by a connecting piece, the connecting piece is required to be removed one by one under the severe smelting working conditions of high temperature, dust, splash and the like in converter steelmaking, and the antifriction cushion block in the narrow space between the baffle seat and the support seat is very difficult to replace because the connecting piece can deform, adhere and seize in the high temperature, dust and splash environment, can not be detached at all, can only be cut and replaced, and increases the maintenance cost and maintenance time of equipment.
In addition, in both the way of the pendulum bar 6 or 7 statically fixing guide mechanism adopted in the patent of tilting converter with the patent number ZL93117357.4 and the way of providing the guide seat for limiting the movement of the converter shell along the axial direction of the trunnion in the scheme disclosed in the patent of ZL201210291941.6, namely the arrangement structure of the four-point connecting rod hanging device of the converter, not only the whole converter suspension support system is complicated and hyperstatic overconstrained, but also the self-adaptive working condition of the converter suspension system is not facilitated, and the maintenance workload of equipment is increased, and in practice, the method is not necessary after engineering application verification.

Here, the symmetry center of the vertical link mechanism 3 itself substantially refers to the center plane n; here, the horizontal link mechanism 4 is located above the vertical link mechanism 3, which means that: when the furnace body 1 is in the vertical posture, the horizontal link mechanism 4 is completely positioned right above the vertical link mechanism 3 or positioned slightly deviated from the position right above the vertical link mechanism 3.

In some embodiments, referring to fig. 2, the centers of symmetry of each set of vertical linkages 3 themselves are coplanar with the trunnion ring body 21 axis. Of course, in practical implementation, the symmetry center of the vertical link mechanism 3 may not be coplanar with the trunnion ring body 21, as long as it is located in the area of the first included angle radiation.

The invention has the beneficial effects that:
1. the verification of finite element analysis and a large amount of engineering practice: according to the hanging structure, the vertical connecting rod mechanism 3 is arranged in a specific angle area (namely, an area with a first included angle alpha radiation), and the horizontal connecting rod mechanism 4 is arranged over the vertical connecting rod mechanism 3, so that the vertical connecting rod mechanism 3 also becomes a main mechanism for restraining the alternating dislocation displacement of the horizontal connecting rod mechanism 4 on a supporting surface, no matter the vertical connecting rod mechanism 3 and the horizontal connecting rod mechanism 4 are far away from the position with the maximum alternating dislocation amount (15 mm) between the furnace body 1 and the backing ring 2, the horizontal connecting rod mechanism 4 is positioned in the position range with the minimum alternating dislocation displacement (1 mm-2 mm) between the furnace body 1 and the backing ring 2, the 'base surface' of the horizontal connecting rod mechanism 4 is more firm to install, the working condition is more ideal, the service life is longer, and the arrangement optimization of the whole lower hanging self-adaptive hanging structure of the converter is realized. Patent ZL93117357.4 discloses that the main reason for placing the horizontal link support mechanism close to the underside of the trunnion ring is to direct the tilting force to the load-bearing trunnion as much as possible, so as to keep the trunnion ring in the stress-free state to the maximum extent, but neglecting that this position is the position where the "alternating offset" of the entire trunnion ring is the largest due to the bending and twisting action and the most unfavorable working condition of the horizontal link, in fact, the overall rigidity and strength of the ring body of the converter trunnion ring and the trunnion device are much greater than those of the horizontal link mechanism, and in contrast, the horizontal link mechanism installed here has very weak mechanical properties in rigidity and strength, so that it is the best position to install the horizontal link mechanism at the position of small "alternating offset" between the body of the converter device and the trunnion ring.
2. The guide seat for limiting the converter shell to move along the axial direction of the trunnion in the tilting process is removed from a pendulum rod 7 statically determined guide mechanism in the patent ZL93117357.4 and a guide seat used for limiting the converter shell to move along the axial direction of the trunnion in the patent ZL201210291941.6, so that a horizontal support mechanism for suspending the converter is simplified, the problem of hyperstatic over-constraint of the existing suspension structure is solved, the self-adaptive working condition of a converter suspension connecting rod mechanism is facilitated, and the equipment maintenance workload is reduced.
3. More importantly, the converter self-adaptive hanging structure of the utility model utilizes the paired horizontal link mechanism and vertical link mechanism to form two-point supporting structure on the upper and lower sides of the supporting ring, compared with the mode that only the horizontal link mechanism is arranged below the trunnion on each side to form single-point support in patent ZL93117357.4, the hanging structure of the invention can be more suitable for the working condition of the large-tonnage converter.
4. The simple and reliable hanging system under the converter, perfect and optimum static design between the backing ring and the furnace shell, flexible and strong connection between the backing ring and the furnace shell, uniform load distribution of each connecting rod and self-adaptive compensation of thermal deformation. High mechanical force and heat load, long service life and harsh environment.

6. Compared with the mode of a blocking seat mechanism, the connecting rod mechanism does not need to be adjusted, and in the hanging structure, both the horizontal connecting rod mechanism and the vertical connecting rod mechanism have the self-adaptive action capability, are insensitive to the environment lacking of grease lubrication, can not generate abnormal sound when the converter tilts and operates, have longer service life and ensure that equipment is free of maintenance for a long time.
