Determination of deformation and instalation into design position of rotary kilns by means of geodetic methods
AZOVSTAL, September 2015
“Determination of deformation and installation into design position of rotary kilns by means of geodetic methods”
We provide maintenance of rotary kilns at cement factories
We have a patented technology of static and dynamic* rotary kilns measurements.
*(“hot alignment” without technological process shutdown)
Our work consists in the following:
Installation of rotary kilns in the design position
Identification of wear type and mechanisms deformation
Determination of axes straightness
High accuracy of kinematic parameters determination
All work is carried out without interruption of the technological process
All work is carried out without interruption of the technological process, which allows not to influence the activity of the enterprise. Implementation of this technology allows to install the equipment in accordance with projects which reduces percentage of defects in finished products.
For such objects we create a high-accuracy reference network, which will be the basis for measurements. This network is necessary both for static measurements and “hot” alignment. The accuracy of points determination in this network is 0.5 mm for a rotary kiln 90 m in length.
The creation of a high-precision network around the kiln
To factor in the changes in the speed of kiln rotation during execution of geodetic measurements we use a laser triangulation sensor synchronized with other equipment.
Data visualization on PC via a radio channel (online). Data for bandages, rollers, shells is received in reflectorless mode ( without installing anything on the elements of the kiln)
Technical audit of kilns without shutdown reveals the problem parts
