Mobil Vacuoline™ 525 circulating oil helped decrease oil consumption by 50%

Situation

Located in Russia, the Severstal Cherepovets Steel Mill is one of the world’s largest integrated steel mills. The mill had used a competitor’s oil in the circulation system of the hot rolling mill. Plain bearings were frequently damaged. Bearing wear, emulsion problems and deposit formation increased bearing temperatures, leading to a reduction of rolling speed.

Recommendation

ExxonMobil recommended Mobil Vacuoline™ 525 circulation oil, with excellent water separation performance and anti-wear properties. The Mobil Vacuoline™ 500 Series of lubricants are high-performance, heavy-duty circulating oils designed for steel mills.

Result

During three years of successful service, Mobil Vacuoline™ 525 oil helped the customer decrease their oil consumption by 50%*, eliminating lubricant-related bearing failures. The customer no longer experienced emulsion problems, oil deposit formation or equipment corrosion.

*This proof of performance is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.
