Description
Technical field
The utility model belongs to mechanical equipment technical field, discloses the coupling unit of a kind of converter shell and backing ring.
Background technology
The coupling unit of converter installation furnace shell and backing ring, it is installed between the furnace shell and backing ring of converter installation, is used for furnace shell is supported or hangs at backing ring, is used for bearing the various load of converter rotation process, absorbs the relative deformation between furnace shell and the backing ring.The kind of converter installation furnace shell and backing ring coupling unit is more both at home and abroad at present, as 3 two spherical bracetypes, steel cable suspension type, the blue connection of three point method etc.What present domestic use was maximum is 3 two spherical support structures (Nippon Steel) or three connecting rod suspension types and block seat array configuration, find in the actual use, any type of three-point suspension no matter, a because middle part that must be installed in the backing ring ring body in three suspension centres, cause the degree of disturbing at converter trunnion ring middle part bigger, converter is in 360 ° of umklapp processes, can produce the bigger play of elasticity up and down between body of heater and the backing ring, cause block seat contact bearing surface that bigger slip takes place under heavy duty, this slip is particularly evident to mammoth conveter, and theoretical analysis and practical measurement all show this slippage of mammoth conveter is reached 12～15mm.This slippage has been brought bigger negative impact to the quality of converter, mainly contains: converter in tapping later stage and deslagging process, reaches and can send abnormal sound and impact when deslagging course recovery orthostatism in operation process, and this is deleterious to converter.Certainly solve, but finite element analysis shows that also depend merely on the height that increases backing ring, it is limited that it improves effect by the rigidity that strengthens the converter system of connections.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the coupling unit of a kind of converter shell and backing ring is provided.This device can absorb the relative deformation of all directions between furnace shell and the backing ring, has good system's joint stiffness simultaneously, can effectively reduce the play of elasticity up and down between body of heater and the backing ring and the body of heater in the process of fascinating with respect to the swing of backing ring, reduce converter and in operation process, send abnormal sound and impact, by the reliability of each moving member.This system's manufacturing processing is convenient, easy to loading and unloading quick, improves the safety in operation of converter; The reliability of raising equipment reduces maintenance cost, is the desirable converter coupling unit of steel-making converter backing ring and furnace shell.
The utility model is realized in the following way: the utility model comprises backing ring and furnace shell, it is characterized in that four groups of linkage assemblys are symmetrically distributed with the ring trunnion axis by certain angle, backing ring and furnace shell are connected, go up the top that block seat mechanism is installed in the ring trunnion side respectively for two, two following block seat mechanisms are installed in the below of ring trunnion side respectively, above or below the backing ring middle part 1～2 group of guide holder is installed, 1 group of guide holder is installed at least.The angular range of each linkage assembly suspension centre and backing ring axis is 15～60 °, and angle is more little, and system stiffness is good more, but because the gudgeon side will be equipped with down block seat, so must reserve down the installing space of block seat.
The universal connecting mode of the adoptable connecting rod two ends of linkage assembly dress oscillating bearing, bearing pin passes oscillating bearing and furnace shell hanger and backing ring hanger, and the furnace shell hanger is welded on the furnace shell, and the backing ring hanger is welded on the backing ring.The universal connecting mode that linkage assembly also can adopt pinblock and oscillating bearing to be combined into.
The last block seat mechanism of coupling unit is installed in the top two gudgeon sides of backing ring ring body, furnace shell seat on each in the block seat mechanism is welded on the furnace shell, two backing ring block seats are welded on the backing ring, and block seat can contact support by face by supporting backing plate on furnace shell seat and two backing rings.
The following block seat mechanism of coupling unit is installed in the below two gudgeon sides of backing ring ring body, furnace shell seat under each in the block seat mechanism is welded on the furnace shell, two backing ring block seats are welded on the backing ring, and block seat can contact support by face by supporting backing plate under furnace shell seat and two backing rings.
Block seat mechanism and following block seat mechanism all are very important in this device on backing ring and the furnace shell, if have only last block seat mechanism or have only following block seat mechanism, the load of converter block seat in rotation process can strengthen, the relative deformation of furnace shell and backing ring also can strengthen when converter was simultaneously changeed 90 °, this can increase the slip and the load of linkage assembly internal mechanical part, reduces the reliability and the life-span of linkage assembly.
Last block seat mechanism and following block seat mechanism should be installed in by the ring trunnion side, and this meets mechanics principle, and the rigidity of converter coupling unit is better.
There is one to support backing plate between this coupling unit furnace shell seat and the backing ring, following furnace shell seat can contact support by face with backing ring by supporting backing plate, in the converter use, adjust this gap, can more effectively reduce the friction between block seat, can eliminate the abnormal sound and the impact of converter fully, make the converter coupling unit non-maintaining for a long time.
This converter coupling unit can reduce the device fabrication cost, improves the safety in operation of converter; The reliability of raising equipment reduces and safeguards.Be that the ideal converter connects erecting by overhang.
