Improving Rolling Mill Lube Oil Performance and Useful Life - Part 2: Prevention

By Aaron Hoeg on Fri, Feb. 22, 2013

If you're just tuning in and didn't catch the first part of our steel mill and lube oil series, click here.

When we left off, we just determined how the high levels of emulsified water and high particulate contamination levels work together to cause bearing failure and reduce oil life. So, how do we prevent this expensive combination from happening? We're glad you asked!

Improving Rolling Mill Lube Oil Performance and Useful Life - Part 1: Quality

By Aaron Hoeg on Fri, Feb. 15, 2013

steel mill equipment and lube oil

Premium oils keep steel mills running. It's crucial to protect their quality in order to keep the mills fully functioning. 

In both hot and cold steel mill production, high-demulsibility lubricant is used for backup roller bearing lubrication. Some of these oils are referred to as SD, which stands for super-demulsibility. Not surprisingly, these SD oils are a premium product and come at a premium price. If a manufacturer wants to invest in these big-ticket oils, they obviously want to go to great lengths in order to keep them clean and fully functioning.

Join us for this three-part series as we take an in-depth look at improving rolling mill lube oil performance and useful life.

Hy-Pro Vacuum Dehydrators Improve Mill Reliability

 We Hy-Pro Vacuum Dehydrators already know that maintaining low levels of water in rolling mill lubricating oil can help improve uptime, extend oil life, prevent bearing failures and increase profitability. But, what about an actual example of how a vacuum dehydrator has improved mill reliability?

Oil Vacuum Dehydrators: Managing Water in Rolling Mill Lubricating Oil

By Aaron Hoeg on Fri, Aug. 31, 2012

In our last post, Improving Rolling Mill Oil with Vacuum Dehydration, we discussed how the demulsibility (ability of the oil to separate from water) of oil is an important characteristic that greatly influences the effectiveness of the lubricant and how a loss of demulsibility can result in poorly lubricated bearings, unplanned downtime and premature fluid replacement.

Improving Rolling Mill Lubricant Oil with Vacuum Dehydration

By Aaron Hoeg on Tue, Aug. 07, 2012

Benefits of Vacuum Dehydration for Rolling Mill Lubricant Oil

Steel mills typically use lubricants with high demulsibility for rolling mill back-up roller bearings and chocks since relatively high levels of water contaminate the oil from quenching and descaling processes. These rolling mill lubricant oils may be known as Morgoil as they are commonly used on Morgan rolling mill systems.
