Description
Technical field
The present invention relates to blast-furnace equipment mounting technique fields, specifically, being related to a kind of blast-furnace tuyere flange level measurement
Method.
Background technique
The installation of blast-furnace tuyere equipment is related to the absolute altitude control of multiple tuyere flanges.Fig. 1 is schematic diagram, shows existing skill
The detection method of tuyere flange absolute altitude under art.Referring to Fig. 1, under the prior art, the absolute altitude of blast-furnace tuyere flange is to pass through level
Instrument 10 measures the absolute altitude of each tuyere flange one by one.Specifically, setting up level 10 in furnace bottom, then by blast-furnace tuyere
The installed height mark datum mark of flange is moved to the installed position of blast-furnace tuyere flange, and the point on the basis of the position, to current
The absolute altitude of blast-furnace tuyere flange measures.
However, the quantity of Modern Large Blast Furnaces tuyere flange reaches 30 or more, pair under the above-mentioned this prior art
Flange carries out measuring the mode of absolute altitude is after every what a tuyere flange of installation one by one, it is necessary to set up level and be checked
Measurement.After the installation is completed to all tuyere flanges, the absolute altitude of each tuyere flange of record is compared, to check that confirmation exists
The elevation data of installation tuyere flange whether is influenced in adjustment tuyere flange central process, also, is checked and confirmed adjacent wind
Mouth flange elevation difference, and according to above-mentioned measurement data, the absolute altitude of multiple tuyere flanges is adjusted.In addition, when delivery receiving acceptance,
There is still a need for carry out detection examination to multiple flange absolute altitudes.

Blast-furnace tuyere flange absolute altitude datum mark height it is consistent；Step 3 projects laser beam according to the laser measuring equipment,
Adjust the height of each tuyere flange.
Preferably, in the step 2, the laser measuring equipment can be laser leveler.
Again preferably, in the step 1, the laser measuring device for measuring can be set in any one height to be measured
At hanging scaffold position on the inside of furnace tuyere flange, and using the position as starting point, laser is projected simultaneously to the two sides of horizontal direction, it can be with
The tuyere flange of two sides at the blast-furnace tuyere flange position is measured.
As described above with practice it is found that first will in blast-furnace tuyere flange level measurement method of the present invention
The absolute altitude datum mark of blast-furnace tuyere flange leads to fixed point position on the outside of last furnace shell, is then arranged at any one flange position
Laser leveler, then adjusts the mounting height of the laser level, and the height for the laser that it is projected and current location
The absolute altitude datum mark of the blast-furnace tuyere flange at place is consistent, meanwhile, using the water at laser leveler position as starting point, at the position
Flat two sides emit laser, and according to the height of the laser beam, the elevation location of each blast-furnace tuyere flange are adjusted, when blast furnace wind
Mouth flange after the installation is completed, can set up laser measuring equipment by same step at an arbitrary position, pass through laser beam height
The installation site of blast-furnace tuyere flange is intuitively examined in degree position, horizontal instead of carrying repeatedly is needed in the prior art
The method that instrument measures multiple tuyere flanges on blast furnace one by one improves the standard of measurement while realizing rapid survey
Degree, then improves the installation effectiveness of blast-furnace tuyere flange equipment.In conclusion blast-furnace tuyere flange measurement of the present invention
Method has simplified measuring process, can significantly improve the level measurement accuracy of blast-furnace tuyere flange, effectively improve blast furnace wind
The installation effectiveness of mouth flange, while reducing artificial saving working hour.
