“Zaporizhstal” improves diagnostics of equipment


“Zaporizhstal” of Metinvest Group purchased coordinate measuring system based on laser tracker Leiса АТ403. The high precision device will help improve quality of large-sized production facility diagnostics and efficiency of preventive measures as well as reduce maintenance and repair duration. The plant investments in the equipment amounted to over UAH 6 mln.

“To maintain competitive positions in the markets is a high-priority task for our plant. It requires from us production con-trol at all stages, but in the first place, equipment control, decrease in its scheduled and unscheduled downtime, correct maintenance and repair of the production facilities based upon the data of production unit condition fine monitoring. As the result of the diagnostics improvement, we reduce losses and increase the equipment reliability and, as a conse-quence, our competitive ability”, says Oleksander Myronenko, General Director of PJSC “Zaporizhstal”.

A new laser tracker will make it possible to perform high precision dimensional and positional check of the equipment parts. The slightest deviations from the design position of foundations, housings, stands, gear boxes will be immediate-ly detected by the device, and reference information will be generated based on the findings. Any variations of flat-ness, roundness, straightness, symmetry and other characteristics will also be indicated in the summary intended for the plant specialists. Based on the data received, engineering service specialists will be able to analyse a situation, de-velop and implement corrective activities to eliminate non-conformities and thus increase turnaround time between re-pairs, improve reliability of the equipment and reduce release of nonconformity products.

The specialists of the plant technical diagnostics department took a course of theoretical and practical training in the new equipment and its software operation. A new coordinate measuring system based on laser tracker Leiса АТ403 already confirmed its efficiency at the end of September, during rolling mill equipment major overall in “Zaporizhstal” blooming mill and hot rolling mill.
