Use of Thickened High Water Hydraulic Fluid in Flat Rolled Steel Production

摘要

Thickened HFA-E hydraulic fluid is in the class of most fire-resistant hydraulic fluid as tested according to ISO 15029-2. A thickened HFA-E hydraulic fluid demonstrated improved lubricity, load carrying capabilities, corrosion protection, and bacterial resistance in comparison to the standard HFA-E (95/5) high water hydraulic fluid while in operation in the roughing and finishing mill hydraulic systems at the ArcelorMittal Dofasco steel production complex. The improvements in hydraulic fluid properties and hydraulic system operation resulted in increased system reliability, decreased maintenance costs, and extended equipment life for the roughing and finishing mill hydraulic systems.
