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.

Demulsibility is the ability of oil to separate from water. Oil and water naturally separate because like molecules attract each other. Oil sticks with oil, water sticks with water. Oil is "hydrophobic", or "afraid of water," which is a benefit when it comes to fluids like turbine oil.

At the end of Part 2, we discussed the winning nature of vacuum dehydration. If you missed Part 1 in the series, you can find it here.
Did you know that hydrogen is the friendliest molecule - meaning that it is most likely seeking partners to attach to? Similarly, the suspended particles in oil actively look for particles to join forces, so they pair with the water.
This particulate contamination is the catalyst guilty of continuing the degradation of the oil and the increase of emulsified water. The more water there is, the more oxidation that occurrs. This also increases various acids that form as the molecules break down. These acids attack seals, hoses, pumps and metal.

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!
