Abstract

Historically, cold rolling lubricants have been classified as emulsions or dispersions, depending on emulsion stability and oil droplet particle size. Emulsions generally are used for material requiring moderate reductions and a clean surface. Dispersions allow the mill to take greater reductions but generally leave higher levels of oil on the strip. Stabilized Dispersion Technology combines the benefits of both emulsion and dispersion technologies. Using a novel emulsifier system, a cold rolling lubricant has been formulated which furnishes high lubricity, a clean steel surface, and good tramp oil rejection. The emulsifier system produces a consistent particle size over the life of the solution. This consistency gives predictable lubrication, high detergency, and extended solution life by rejecting tramp oils, iron, and rolling debris. The ability to reject these contaminants produces a virtual self-cleaning system. Several case studies are presented which illustrate the benefits seen on modern cold reduction mills. Data from a range of grades, gauges, reductions and sizes are presented to compare Stabilized Dispersion Technology to previous systems.
