Hot strip mill modernization at JSW Steel Vijayanagar Works, India

Danieli India has executed the revamping of the lower housing part of vertical edger for the existing HSM -1 at JSW Steel Vijayanagar Works, which was designed, manufactured at Danieli India design and manufacturing center, in Chennai.

Danieli Service performed a detailed mill audit, checking wear and tear conditions of the edger stand and other associated equipment, and developed an engineering solution aiming for a quick restoration of the damaged edger housing to original dimensional tolerances.

An accurate preliminary analysis, good organization and round the clock, on-site work during the shutdown phase, allowing the completion of the task 11 days ahead of schedule.

The strategic points of the good job execution which led to JSW high appreciation were:

> Detailed study and condition analysis of the area prior to shut down.

> Setting pre-condition and detailed activity schedule discussion.

> Preparation of effective spindle lifting device and schemes to speed-up dismantling and erection processes.

> Accurate execution plan with contingency to mitigate unplanned downtimes.

> Precise machining of necessary equipment at Danieli quality workshop in Chennai.

> Quick solving of unexpected issues rising from the unpredictable nature of revamping activity.

This experience enriched Danieli India’s ability to better serve customers with similar on-site support through reverse engineering, process and condition analysis, solution engineering and on-site execution.
