Blue Star XH 9655/200-1/3M Case Study
Driving sustainable process improvements within the caster operation of a steel mill is very challenging. The severe environment requires careful planning and control of any operational change to avoid production risks. When this steel manufacturer began experiencing a significant reduction in their average bearing life and reclaim rates, a large increase in maintenance costs was incurred. Bearings have typically been able to be reclaimed seven times before requiring replacement.
• Improve bearing life and reclamation frequency. • Extend the segment tonnage between rebuilds. • Reduce the volume of grease used.
• Determining optimal grease thickener and base oil. • Ensuring that the grease will pump in below zero environment. • Implementing the grease transition without impeding production.
A DuBois team of technical experts partnered with the manufacturer to determine what factors contributed to the reclaim reduction and determine an ideal high-performance lubricant that would protect the bearings and significantly reduce their bearing expenditures. Blue Star XH 9655/220-1/3M was deemed a suitable option through a series of laboratory evaluations. This innovative technology has drastically increased the level of lubrication and water resistance. Compatibility with the existing grease allowed for a seamless transition throughout the caster.
• Doubled the load wear and weld load performance for improved bearing protection. • 87% reduction in water wash out improves the grease’s sealing ability and extends lubrication cycles to reduce usage. • Improved grease performance achieved without sacrificing pumpability during freezing weather conditions. • Compatible grease technologies for seamless transition in grease lubrication system.
