OEMK completes overhaul of Rolling Mill 700

16 October 2020

OEMK (part of Metalloinvest) completes a scheduled overhaul of the Rolling Mill 700, which produces long steel products and tubular and square billets with a capacity of 2.4 million tonnes.

Rolling Mill 700 is one of OEMK’s most important facilities. The uninterrupted supply of rolled steel to the domestic and international markets depends on its high-quality and seamless operation, and therefore the completion of the overhaul in a comprehensive and timely manner was essential.

Among the key works which have been completed are the replacement of the bearings set in the gearbox of the Vertical Rolling Mill Stand #3 of the first group of the Continuous Billet Mill, repairing of the upper spindle of the Duo-Reversible Stand 1,000 and of the foundations of the tugs of the hot-cutting saw section, replacement of the controller in the technological automation system of the refrigeration section, as well as crane runways in the spans of shipment lots and mechanised rack sections.

Sensors for the stationary diagnostic system for the technical condition of the equipment were installed onto the duo-stand and all rolling mill stands of Rolling Mill 700. These will enable the real-time monitoring of equipment performance. In order to launch the system by the end of the year, installation works for the switch and control cabinets of the system are planned for November.

Roman Soldatkin, Deputy Head of Equipment at Rolling Mill #1, said: “This system has been designed to automatically control and diagnose level of vibrations and temperatures, shock impulses of technological units, as well as identifying various flaws. In the future, we will compile all the data about the equipment in the situational-analytical centre, enabling us to quickly identify faults, and to eliminate them efficiently and systematically in order to prevent equipment failures.”

Alexander Yudin, Equipment Manager at OEMK, added: “The project has been implemented as part of Metalloinvest’s corporate programme to transform its maintenance and repair processes. One of the key priorities of this programme is to introduce the principle of reliability and a risk-focused approach to equipment maintenance. Stationary diagnostic systems of the equipment are critical in this process, allowing us to monitor their technical condition online, plan implementation of the maintenance procedures and accordingly determine repair costs for the most critical sections and units. Significant progress in this field was made in the course of the overhaul of Rolling Mill #1.”
