Description
Technical field
The utility model is related to a kind of converter bottom height measuring devices, belong to technical field of metallurgical machinery.
Background technology
Capital equipment of the converter as STEELMAKING PRODUCTION, composition includes furnace shell, insulating layer, permanent layer and working lining.Work
Layer is mainly that Mg-C brick masonries form by material, existing to corrode and wash away since working lining is directly contacted with molten steel and clinker
Destruction, be affected to the service life of working lining.
With smelting technique development, the increase of oxygen supply intensity, the application of bottom blowing process and slag splashing technique, for ensure
Good metallurgical effect, working of a furnace stable operation are related to the stability of blowing, directly affect steel quality.The application of bottom blowing process
The mixing power for increasing molten bath, influences the use of refractory furnace bottom, splashes the scrambling of the burner hearth of the application influence of slag technique.Furnace bottom
Normal use is to ensure the premise of metallurgical effect well, with regard to how the next thickness for directly measuring furnace bottom furnace lining is most important.
Some steel mills use infrared thickness measurer of furnace liner at present, and higher due to investing, maintenance cost is higher, and measure essence
Exactness is influenced by slag splashing, directly cannot accurately reflect the height of furnace bottom, and practicability is poor.
Chinese patent（The patent No.：201420636648.3）A kind of tool measuring furnace bottom height is disclosed, was being used
It is had the disadvantage that in journey：（1）It is larger to measure space width, the height of furnace bottom cannot be accurately measured, cannot accurately reflect and come out of the stove
The variation of bottom height.（2）There is security risk in use using measurement tooth different in size, practicability is poor.（3）By
It is directly contacted with furnace bottom in fettling bar tail portion, and in-furnace temperature is higher, fettling bar tail portion flexible type, there are measured deviation asking greatly
Topic.（4）Two people's compounding practices, the convenience of influence used are needed using this survey tool.
Therefore, it is badly in need of developing the device of the thickness of safe and accurate furnace bottom furnace lining.
Utility model content
A kind of simple in structure, safe and reliable, the operation side provided the purpose of the utility model is to overcome disadvantages mentioned above
Just accurate device, is measured.
The utility model realizes described problem using following technical scheme：
A kind of converter bottom height measuring device, by handle, measurement star, measurement ring, measurement bar, measurement bar tail portion solid
Composition, handle are vertically welded in measurement bar one end, and measurement ring set is on measurement bar and can be slided on measurement bar.
The converter bottom height measuring device, it is equal that measurement star is provided in measurement club head one end quarter interval 10mm
Lines, quantity are 6-10 items.
The converter bottom height measuring device, handle are hollow steel pipe with measurement bar.
The converter bottom height measuring device, handle are 45 millimeters -50 millimeters with measurement shank diameter.
The converter bottom height measuring device, measurement bar tail portion solid is solid rod iron.
The converter bottom height measuring device, a diameter of 45 millimeters -50 millimeters of measurement bar tail portion solid, with measurement bar
Diameter it is identical.
The converter bottom height measuring device, measurement pole length be converter height and converter mouth to main operation platform away from
From the sum of more than 2 meters -3 meters.
The utility model is set by measurement of comparison ring set in measurement bar upper metrology championship, and furnace bottom height can be accurately measured.
It only needs one man operation measuring rod to can be achieved with operating, has the effect of reducing site operation personnel.Measuring rod tail portion is using solid
Material avoids deforming during use, measures the phenomenon that being not allowed, influencing measurement accuracy.The utility model is simple in structure, quickly pacifies
Entirely, service efficiency is high, measures accurately, is suitable for converter bottom elevation carrection.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1 handle, 2 measurement stars, 3 measurement rings, 4 measurement bars, 5 measurement bar tail portion solids.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：It is a diameter of 50mm steel pipes to measure bar 4, measures star 2
It is provided in 4 head one end of measurement bar and is carved with 6 ~ 8 equal lines of interval 10mm, measurement ring 3 is covered in 4 outside of measurement bar
An annulus, for comparing out 2 position of measurement star, the long 600mm in 90 ° with measurement 4 head transverse weld of bar of handle 1,
The steel pipe of diameter 50mm, measurement bar tail portion solid 5 is the solid rod irons of a diameter of 50mm.Go out steel in converter or splashes the complete rear survey of slag
Furnace bottom thickness to be measured, converter is shaken to 85 ~ 90 ° of positions, fire door face deslagging side, side fire-screen door reaches fire door and is directed to position,
It measures furnace bottom height devices to be placed on fire-screen door sampling observation panel, measuring rod 4 is pushed by manpower control handle 1 so that degree
After gauge rod tail portion solid 5 arrives at furnace bottom, measures ring 3 and push against fire-screen door sampling observation panel.According to measurement ring 3 in 4 institute of measuring rod
Measurement star 2 position scale, calculate the height of furnace bottom.
