Description
Technical field
The utility model is about a kind of converter steelmaking equipment, particularly relates to the coupling device of a kind of converter body and backing ring.
Background technology
The body of heater of converter is a container that can vert, belong to shell structure, converter body support is on backing ring, drive end gudgeon and travelling end gudgeon is respectively equipped with in the both sides that backing ring is diametrically symmetrical, point-blank and through backing ring diameter, body of heater is divided into both sides by the axis of this gudgeon, side is tapping side to the axis of two ends gudgeon, opposite side is loading side, and body of heater can vert around the axis of gudgeon together along with backing ring.Body of heater and backing ring have heavy duty, fascinate and the feature of high temperature, and not only bear quiet and dynamic mechanical stress load during work, also bear thermal stresses load, these two kinds of loads produce three kinds of stress on body of heater: 1. the stress produced by mechanical load; 2. thermal expansion stress; 3. furnace body temperature skewness and the thermal stresses produced.Therefore, the basic demand that the coupling device of body of heater and backing ring designs is:
(1) can ensure that body of heater is connected on backing ring securely;
(2) owing to no matter being body of heater or backing ring in production operation, under thermal load effect, all thermal expansion deformation will be produced, and furnace body temperature is much higher compared with backing ring temperature, all can occur relative displacement both therefore during thermal expansion radial and axial.If this relative displacement is restricted, will produce additional stress, also can cause destruction time serious, therefore, coupling device should allow, between body of heater and backing ring, relative displacement occurs.
The coupling device principal mode of existing converter body and backing ring is suspension connection device under 3 converters, the patent documentation of " under converter body suspension connection device " is specifically called see utility model name, its application number is CN200720005492, its primary structure is: the hanger of lower portion of furnace body welding and the hanger of backing ring lower weld are linked together by connecting rod and oscillating bearing, suspension connection device under forming one group, suspension connection device under being provided with three groups altogether, wherein two are located at tapping side, from vertical view, the line angle at 45 ° with the axis of gudgeon respectively at two lower suspension connection devices and body of heater center, another is located at loading side, from vertical view, and the line at itself and body of heater center and trunnion axis angle in 90 °.When displacement is expanded with heat and contract with cold in body of heater generation, connecting rod swing, makes body of heater central position remain unchanged.In addition, backing ring is also provided with upper and lower seat device of card in two gudgeon positions; Body of heater being welded with bracket, coordinating with adjusting backing plate between bracket with the seat device of card be welded on backing ring.When converter inclining is to level attitude, by the bracket on body of heater, the load of body of heater is passed to backing ring.This structure belongs to three sling point statically determinate structures.
Under existing 3 converters, suspension connection device was from the practical effect of nearly 6 years, mainly there is following defect:
Under (1) three converter, in suspension connection device, loading side connecting rod is hit comparatively large, and the oscillating bearing life-span is herein shorter, and the recoverable deformation of loading side and tapping side exists larger difference, and body of heater has a small amount of swing in the process of fascinating.
Adjustment backing plate under (2) three converters in suspension connection device is owing to requiring that manufacturing accuracy is very high, therefore, require if the finished product of processing and manufacturing does not reach and come into operation, the ball ring of oscillating bearing is there will be by conquassation after for some time, and lose the function of automatic positoning, and then may appear under the impact force action that fascinates by the situation of cutting off.This can cause no small hidden danger to the safety in production of converter, and stop production to overhaul Ye Huishi enterprise suffers no small financial loss.
Under (3) three converters, suspension connection device is owing to adjusting the replacing of backing plate by space constraint, repair and maintenance difficulty.
Visible, under above-mentioned existing 3 converters, suspension connection device is in structure with in use, still has inconvenience and defect, and urgently improves further.
Thus, the present inventor relies on experience and the practice of being engaged in relevant industries for many years, proposes the coupling device of a kind of converter body and backing ring, to overcome the defect of prior art.
