The blast furnace body expansion measurement device can conveniently measure conditions of longitudinal rising or/and transverse rising of portions of a blast furnace bottom, a hearth, the furnace body, a furnace top and the like, the measurement is simple, convenient and fast, and high in accuracy, and reliable data can be obtained timely; and the blast furnace body expansion measurement device can take measures in time according to the obtained data, effectively prevents the conditions of pull cracks and deformation of a furnace shell, gas leakage, equipment deformation and dislocation and the like from happening, and is favorable for prolonging service life of a first generation furnace, reducing cost, and guaranteeing safety and smooth running of blast furnace process.
Description
Technical field
The utility model relates to a kind of blast furnace dilatometry device, belongs to field of measuring technique.
Background technology
Modern blast furnace belongs to the free-standing blast furnace mostly, and body of heater separates with perimeter frame.After blast furnace comes into operation, body of heater can be heated and the abnormal erosion of harmful element etc. produces expansion because of refractory materials in the stove, " going up continuously " phenomenon, particularly furnace bottom appears, the cupola well high-temperature area affects by refractory materials and serious erosion, more increased the weight of should the zone expansion.Furnace expansion stress is huge, can't suppress.Blast furnace continuously rise can bring the problems such as furnace shell drawing crack distortion, gas leak, Years Of Service shorten, equipment distortion dislocation.Blast furnace rise situation is monitored, in time to take measures according to monitor data, will be conducive to delay blast furnace rise speed, prolong generation stove labour Years Of Service.Yet blast furnace equipment is huge, and rise speed is very slow again, is difficult to Measurement accuracy body of heater rise speed with conventional direct measuring method.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of blast furnace dilatometry device, exactly blast furnace rise situation is measured in good time.
The utility model provides a kind of like this blast furnace dilatometry device, comprise survey meter, it is characterized in that survey meter is fixed on the support, the measuring junction of survey meter contacts with rigidity level bar outer end, this rigidity level bar the inner is fixed on the blast furnace, so that when swollen rising occurs blast furnace, the rigidity level bar that is attached thereto is synchronous shift thereupon also, thereby touches measuring junction and demonstrate displacement data at survey meter.
Described support comprises a vertical bar, be located at the triatic stay on this vertical bar top, be located at the bearing of this vertical bar bottom, bearing is fixed on the platform of blast furnace corresponding position, survey meter is vertically fixed on the triatic stay by standing bolt and nut, in order to the body of heater situation that vertically goes up is measured in good time.
Described support comprises a vertical bar, is located at the bearing of this vertical bar bottom, and bearing is fixed on the platform of blast furnace corresponding position, and survey meter is horizontally fixed on the vertical bar by standing bolt and nut, in order to the body of heater situation that laterally goes up is measured in good time.
Described support is made as a plurality of, be installed in respectively on the furnace foundation platform corresponding with blast furnace, cupola well platform, shaft platform and the throat platform, in order to after corresponding rigidity level bar and survey meter cooperate, the rise situation of Blast Furnace Bottom, cupola well, shaft, furnace roof is measured in good time.
Described rigidity level bar is made as steel pipe or angle steel or channel-section steel, its quantity is made as many corresponding with support, and be separately fixed at furnace bottom, cupola well, shaft and furnace roof position, in order to after corresponding support and survey meter cooperate, the rise situation of Blast Furnace Bottom, cupola well, shaft, furnace roof is measured in good time.
The utlity model has following advantages and effect: adopt such scheme, can be easily to vertical rise at the positions such as Blast Furnace Bottom, cupola well, shaft, furnace roof or/and laterally rise situation measure, not only easy, quick, accuracy is high, and can obtain authentic data in good time, and in time take measures according to obtaining data, effectively avoid the situations such as furnace shell drawing crack distortion, gas leak, equipment distortion dislocation to occur, be conducive to prolong generation stove labour Years Of Service, reduce cost, ensure blast-furnace smelting safety, direct motion.
